6 templates across principal software, standard, ML/AI, senior principal, hardware, and first-principal-at-a-scaling-company roles, each with the IC-leveling clarity and FLSA exemption guidance generic templates skip. Download as DOCX.
A principal engineer is the most senior individual contributor on an engineering team, setting technical direction across many teams through architecture, standards, and influence rather than people management. Writing the job description well starts with two things most templates skip: placing the rung precisely on the IC ladder, since Principal is a distinct level from Staff, Senior, and Distinguished, and stating the FLSA classification, which turns on duties rather than the title.
At FirstHR, these six templates cover the role across contexts: principal software, a discipline-agnostic standard version, principal ML or AI, senior principal, hardware or mechanical, and a dedicated version for a company introducing its first Principal level. The guide to writing a job description covers the fundamentals behind any posting.
TL;DR
A principal engineer is the top individual-contributor rung, setting technical direction across teams through architecture and influence, not people management. It is a distinct level from Staff, Senior, and Distinguished, and the role is FLSA-exempt under the computer-employee or learned-professional exemption, by duties rather than title. There is no federal code for the title; the closest proxy, software developers, has a median near $133,080. Download six templates as DOCX, by rung and discipline.
What a Principal Engineer Does
A principal engineer owns the technical direction of major systems or programs, solves the hardest and most ambiguous problems, sets engineering standards, and multiplies the effectiveness of the teams around them through mentorship and influence. The role is defined by technical scope and organization-wide impact, not by the number of people reporting to it, since a principal leads as a senior individual contributor rather than a manager.
There is no dedicated federal occupation code for the title, because Principal is a seniority designation rather than an occupation. The closest proxy for the most common version is software developers (15-1252), which the Bureau of Labor Statistics defines as designing and developing software, though the principal premium sits well above the base-occupation figures. The templates here are organized by rung and discipline so you can match the posting to the exact level you are filling.
Principal Engineer Duties and Responsibilities
Principal engineer duties cluster into four areas: technical direction, cross-org influence, the hardest problems, and multiplying the team. A strong job description picks the responsibilities from each area that match the specific rung and discipline you are hiring for.
Technical direction
Own architecture for major systems
Set technical strategy across teams
Make high-impact build and buy decisions
Cross-org influence
Lead through influence, not authority
Drive standards across the organization
Advise leadership on technical tradeoffs
Hardest problems
Solve the most complex, ambiguous problems
Identify and mitigate technical risk
Lead design of large, novel systems
Multiplying the team
Mentor senior and staff engineers
Raise the engineering bar
Grow technical capability across teams
The emphasis shifts by version: a software principal leans into systems architecture, an ML principal into model and pipeline design, and a senior principal into company-level strategy. For a structured way to scope the role, the guide to defining job responsibilities walks through the process.

Employment type: Full-time
FLSA status: Exempt [confirm by duties]
Compensation: Base $_____ + bonus + equity; level: __
JOB SUMMARY
[Company Name] is a growing engineering organization introducing its first
Principal Engineer level as the team scales. This version is for a company that has
outgrown a flat ladder and now needs a top IC rung: you will set technical
direction across teams, anchor architecture as the codebase and headcount grow, and
help define what the Principal level means here. Read the note below on when this
level makes sense.
KEY RESPONSIBILITIES
•Set technical direction as the organization scales
•Own architecture for the systems that must scale with growth
•Establish engineering standards and review practices
•Mentor a growing team of senior engineers
•Partner with the CTO or VP on the technical roadmap
•Help define the IC ladder and the Principal level itself

WHEN TO INTRODUCE THIS LEVEL (read before posting)
Engineering-leveling guidance suggests a Principal rung makes sense once an
organization is large enough to need five or more IC levels, often around the scale
of a technical lead for an organization of roughly 50 to 150 engineers. Below that,
a smaller team is usually better served by a Staff or Lead level. If you are using
the title for a top contributor at a smaller company, define the scope clearly so
the level is meaningful.

Leveling and FLSA Classification
This is the part the generic templates skip, and it is what makes a principal engineer posting accurate: placing the rung correctly on the IC ladder, knowing when the level makes sense at all, and stating the FLSA classification. Get these right and the posting reflects a real level rather than a borrowed title.
Principal is a rung on the IC ladder, not a manager title
The first thing to get right is that Principal Engineer is the top of the individual-contributor track, not a people-management role. A Principal leads through technical influence, architecture, and mentorship rather than by managing direct reports, and the role is deliberately distinct from an engineering manager who owns headcount, performance, and delivery. The two tracks usually run in parallel at the same seniority. Define the role around technical scope and impact, not team size, and make the IC nature explicit in the posting so candidates understand they are being hired to multiply the engineering organization, not to manage it. This is general information, not legal advice.
Senior, Staff, Principal, and Distinguished are different levels
Principal sits within a ladder of senior IC rungs, and each is a separate job with distinct scope and pay, so they are not interchangeable. Broadly, Senior owns a feature or service, Staff influences a team or group, Principal sets direction across an organization, and Distinguished operates at the company or industry level. At big tech the mappings are well known: Principal aligns roughly with Amazon L7, Google L8, and the Meta E8 level, with Senior Principal and Distinguished above. Write a dedicated description for the specific rung you are filling rather than reusing a Senior or Staff posting, because the expectations and compensation differ materially at each level. This is general information, not legal advice.
The level only makes sense at sufficient scale
A Principal rung exists to coordinate technical direction across many teams, so it emerges only once an engineering organization is large enough to need it. Common leveling guidance places a Principal as the technical lead for an organization on the order of 50 to 150 engineers, and large companies run only a handful of principals per hundred engineers. Practitioner advice is explicit that smaller teams should keep a flat ladder of three or four levels and not create Principal or Distinguished rungs prematurely, since an inflated title without the scope to back it confuses leveling and pay. If you are a smaller, scaling company, define the scope carefully before adopting the level.
The role is FLSA-exempt, and the title does not decide that
A Principal Engineer is almost always exempt from overtime, but the classification turns on duties and pay, not the title. A software principal typically qualifies under the computer-employee exemption, which the Department of Labor sets at a salary basis of at least 684 dollars a week or an hourly rate of at least 27.63 dollars for a computer systems analyst, programmer, software engineer, or similarly skilled worker performing qualifying systems-analysis and development work. A non-software principal usually qualifies under the learned-professional exemption instead. Because job titles do not determine exempt status, confirm the classification against the actual duties and the salary or hourly test rather than assuming it from the level. This is general information, not legal advice.
Principal Is the Top IC Rung, and Exempt by Duties
Principal Engineer is the senior end of the individual-contributor track, above Staff and Senior and below Distinguished, leading through technical influence rather than people management. It is almost always FLSA-exempt, under the computer-employee exemption for software (salary basis of at least $684 a week or $27.63 an hour) or the learned-professional exemption otherwise. Job titles do not determine status; confirm by duties. This is general information, not legal advice.
The most common leveling confusion is between the senior IC track and the management track. Principal and engineering manager are usually parallel roles at a similar seniority, but they own different things. Use this comparison to decide which role you are actually hiring.

Growing and running teams
If you need someone to own architecture and technical direction, hire a principal; if you need someone to run and grow a team, the engineering manager templates fit better. Many organizations hire both and run the tracks in parallel.
Principal Engineer Pay
Principal engineer pay is high and varies by discipline, location, and company tier. Because the title is a seniority designation, there is no single federal figure for it; benchmark to the discipline and present base, bonus, and equity separately.
No Federal Code for the Title; Proxies Sit High
There is no dedicated federal occupation code for principal engineer, since it is a seniority designation. The closest proxies, as of the May 2024 data, are software developers at a median of about $133,080 (lowest ten percent under about $79,850, top ten percent over about $211,450) and computer hardware engineers at about $155,020 (BLS via O*NET). A principal sits well above these base medians, and total compensation with bonus and equity runs higher still at large tech companies.
Industry pay sources put principal engineer base averages roughly in the $133,000 to $175,000 range, with senior principal and distinguished levels and big-tech total compensation reaching substantially higher. The software developer occupation is projected to grow about 15 percent from 2024 to 2034, much faster than average, so senior technical talent stays in demand. National compensation surveys and BLS data are the best references for setting a range.
Introducing the Level at a Scaling Company
Most companies hiring a principal engineer are large, but the decision that matters for a growing company is when to introduce the level at all. Here is how to think about adding a top IC rung as the organization scales, and how to write the posting once you do.
Most companies that hire a Principal Engineer are large, but a scaling company eventually introduces the level
The Principal title belongs to large engineering organizations, big tech, and later-stage companies that have grown a deep individual-contributor ladder, and those companies usually have dedicated recruiting and leveling functions. The moment that matters for a growing company is the transition: the point where a flat ladder of three or four levels no longer fits, headcount and system sprawl create cross-team technical scope, and a top IC rung becomes worth defining. This page is written to serve both, with standard and discipline-specific versions for established organizations and a dedicated version for the company introducing its first Principal level. Pick the version that matches whether you are filling an established rung or defining a new one.
Introducing a senior IC level is as much a leveling decision as a hiring decision
Before posting a Principal role, a scaling company has to decide what the level means: the scope it owns, how it differs from Staff or Senior below and from an engineering manager beside it, and the compensation band that goes with it. Getting this right keeps the ladder coherent and pay defensible as the team grows, and getting it wrong creates title inflation that is hard to undo. The leveling section and the dedicated scaling-company template on this page are built to help define the rung deliberately. Settle the scope and the level definition first, then write the description, so the posting reflects a real rung rather than a title borrowed from a larger company.
However senior the hire, the offer and onboarding still have to be handled
Once you hire a Principal Engineer, the people side is ordinary operations made specific by seniority: a clear offer that states the level, base, bonus, equity, and exempt classification, the I-9 and tax forms, system and repository access, and a focused first-quarter plan for a senior IC who will set technical direction. FirstHR fits the people-operations side for a scaling company: e-signature for the offer letter, an onboarding wizard and task workflows for access and the first-quarter plan, document management for signed forms and agreements, and an org chart to place a senior IC alongside the management track. To be clear about scope, FirstHR is an onboarding and HR platform, not a leveling, compensation, or payroll system, and it does not run payroll or administer benefits, so pair it with those providers. Applicant tracking is coming soon.
From Hiring to Onboarding
The job description is step one. Once a candidate accepts, the same document becomes the basis for the offer and the onboarding, and for a senior IC who will set technical direction, getting the level, classification, and first-quarter plan right from the start matters.
Send the offer with the level
Confirm the level, base, bonus, equity, and exempt classification in writing, with the offer letter ready to e-sign.
Confirm the classification
Document the exempt basis, computer-employee or learned-professional, against the actual duties and the salary or hourly test, not the title.
Set up access and the first quarter
Provision systems and repository access, and give a senior IC a focused first-quarter plan for the technical scope they will own.
Store the records
Keep the signed offer, equity and IP agreements, I-9, and tax forms organized and current.
Once your offer is ready, the offer letter template handles the next step, and an onboarding template gives a senior hire a structured start. FirstHR connects the offer, e-signatures, the onboarding workflow, document management, and org-chart placement in one place, so a scaling company can run the same process every time it hires. FirstHR is an onboarding and HR platform, not a leveling, compensation, or payroll system, so connect those separately. Applicant tracking is coming soon to FirstHR.
For early-stage hiring more broadly, the startup hiring guide covers the basics of building a team from the first hires up.
Key Takeaways
A principal engineer is the top individual-contributor rung, setting technical direction across teams through architecture and influence, not people management.
Principal is a distinct level from Staff, Senior, and Distinguished; write a dedicated description for the exact rung rather than reusing a Senior or Staff posting.
The role maps roughly to Amazon L7, Google L8, and the Meta E8 level, and exists only once an organization has a deep IC ladder.
It is FLSA-exempt by duties, not title: software under the computer-employee exemption, non-software under the learned-professional exemption.
There is no federal code for the title; the closest proxy, software developers, has a median near $133,080, and a principal sits well above it.
A scaling company should define the scope and pay of the level deliberately before introducing it, around the point an org needs five or more IC levels.
Frequently Asked Questions
What does a principal engineer do?
A principal engineer is the most senior individual contributor on an engineering team, setting technical direction across multiple teams rather than managing people. The work clusters into four areas: technical direction (owning architecture for major systems and making high-impact build and buy decisions), cross-org influence (leading through influence rather than authority and driving standards across the organization), the hardest problems (solving the most complex and ambiguous technical problems and mitigating risk), and multiplying the team (mentoring senior and staff engineers and raising the engineering bar). The title spans software, machine learning, hardware, mechanical, electrical, and systems engineering. It is a technical-authority role defined by scope and impact, not headcount. This is general information, not legal advice.
What is the difference between a principal engineer and a staff engineer?
They are adjacent rungs on the same individual-contributor ladder, with Principal sitting above Staff. Broadly, a staff engineer influences a team or a group of teams, owning the technical direction of a significant area, while a principal engineer sets direction across an entire organization and is expected to have broader, longer-horizon impact. Above Principal sit Senior Principal and Distinguished Engineer, which operate at the company or industry level. In big-tech mappings, Principal aligns roughly with Amazon L7, Google L8, and the Meta E8 level, with Staff a rung below. Because scope and compensation differ materially at each level, write a dedicated job description for the specific rung you are filling rather than reusing a Staff or Senior posting. This is general information, not legal advice.
Is a principal engineer exempt or non-exempt under the FLSA?
A principal engineer is almost always exempt from overtime, but the classification depends on duties and pay, not the title. A software principal typically qualifies under the computer-employee exemption, which the Department of Labor sets at a salary basis of at least 684 dollars a week or an hourly rate of at least 27.63 dollars, for a computer systems analyst, programmer, software engineer, or similarly skilled worker performing qualifying systems-analysis, design, and development duties. A principal in a non-software discipline such as mechanical or electrical engineering usually qualifies under the learned-professional exemption instead. Because job titles do not determine exempt status, confirm the classification against the actual job duties and the applicable salary or hourly test rather than assuming it from the level. This is general information, not legal advice.
Is a principal engineer the same as an engineering manager?
No. A principal engineer and an engineering manager are typically parallel roles at a similar seniority, but on different tracks. A principal engineer is the top of the individual-contributor track, leading through technical influence, architecture, and mentorship without managing direct reports. An engineering manager is on the management track, owning headcount, hiring, performance, and delivery for a team. Many organizations deliberately run the two tracks side by side so that deep technical talent can advance without being forced into management. When writing the job description, make the track explicit: a principal posting should emphasize technical scope and influence, while a manager posting should emphasize people leadership and team outcomes. Confusing the two leads to mis-hires and leveling problems. This is general information, not legal advice.
How many years of experience does a principal engineer need?
Most principal engineers have roughly 10 to 20 years of experience, and the level is generally two to three rungs above Senior. There is no genuine junior or entry-level principal engineer, because the role is defined by a track record of organization-wide technical impact that takes many years to build. A senior principal engineer usually has even more experience, often 15 or more years, reflecting company-wide or industry-level scope. That said, years of experience are a rough proxy, not the real bar: the actual test is demonstrated technical depth and the ability to set direction and influence across many teams. Write the requirement around scope and impact, with an experience range as a guide, rather than treating a year count as the qualification. This is general information, not legal advice.
How much does a principal engineer make?
Principal engineer compensation is high and varies widely by discipline, location, and company tier. There is no dedicated federal occupation code for the title, since it is a seniority designation rather than an occupation, so the closest proxies come from the broader engineering occupations. As of the May 2024 data, the federal median for software developers was about 133,080 dollars and for computer hardware engineers about 155,020 dollars, and a principal sits well above those base-occupation medians. Industry pay sources put principal engineer averages roughly in the 133,000 to 175,000 dollar base range, with total compensation including bonus and equity reaching far higher at large tech companies. Benchmark to the specific discipline, level, and market, and present base, bonus, and equity separately. This is general information, not compensation advice.
When should a company create a principal engineer level?
A company should introduce a Principal level only once its engineering organization is large enough to need a deep individual-contributor ladder. Common leveling guidance places a principal as the technical lead for an organization on the order of 50 to 150 engineers, and large companies run only a handful of principals per hundred engineers. Practitioner advice is explicit that smaller teams should keep a flat ladder of three or four levels and avoid creating Principal or Distinguished rungs prematurely, because a title without the scope to support it creates leveling and pay problems that are hard to undo. A scaling company approaching that size should define the scope and compensation of the level deliberately before posting the role. This page includes a dedicated template for that situation. This is general information, not legal advice.
What should a principal engineer job description include?
Start by naming the exact rung and discipline, whether principal software engineer, principal ML engineer, senior principal, or a hardware or mechanical principal, since scope and pay differ at each. Include a short company summary, a job summary that frames the role as a senior individual contributor and technical authority, and responsibilities grouped into technical direction, cross-org influence, the hardest problems, and multiplying the team. State the experience range and the technical depth expected. The most valuable additions that generic templates skip are an explicit level-and-ladder note that distinguishes Principal from Staff, Senior, and the management track, and an FLSA classification line covering the computer-employee or learned-professional exemption. Close with an equal opportunity statement and clear apply instructions. This is general information, not legal advice.
