HR Roles and Responsibilities: Every Role Explained, From Coordinator to CPO

Human resources roles range from entry-level administrative positions to C-suite executives who shape company strategy. I run a small company and build HR software for the owners, office managers, and HR managers who run HR at small businesses, and the mistake I watch for most is hiring for an HR title before the work calls for it.

Titles, responsibilities, and salary ranges change at every level, and which roles a company actually needs depends on its size and on how much HR work it carries. A small startup needs a very different HR setup than an enterprise, yet most guides describe HR roles as though every business has a full HR department.

This guide covers every major HR role from coordinator to Chief People Officer (CPO) or Chief Human Resources Officer (CHRO), the 7 core functions these roles support, salary benchmarks, and the generalist vs specialist question. Above all, it answers the practical question: which HR roles you actually need at each stage of growth, and which ones software can handle instead.

The 7 Core Functions of HR

Every HR role exists to support one or more of seven core functions: recruiting and talent acquisition, onboarding, compensation and benefits, learning and development, employee relations, compliance, and HR technology and data. Start with the functions and the roles fall into place, because each role is essentially a bundle of responsibilities drawn from this list.

At an enterprise, each function may have its own specialist or team. At a small business, one person (the founder or an HR generalist) covers all seven.

HR Job Titles: The Complete Hierarchy

HR titles run in six bands: entry, mid-level, senior, director, VP, and executive. Each band is a step up in scope rather than a different kind of work, and the wage benchmarks below are read off the Bureau of Labor Statistics occupational codes closest to those jobs.

Every figure in that column comes from the Bureau of Labor Statistics Occupational Employment and Wage Statistics survey (May 2025). Note what the classifications do and do not cover: BLS publishes no occupation for an HR director, a VP People, or a CPO, so those rows are benchmarked against the nearest published code rather than measured directly.

Make two adjustments before you put any of these numbers in an offer. Industry moves them, and the same title pays differently in technology than in education. Geography moves them more: BLS publishes OEWS estimates by state and by metropolitan area, so benchmark against your own metro rather than the national median.

Entry-Level HR Roles

Entry-level HR roles are administrative. They run the paperwork, the scheduling, and the records that every other HR activity depends on. At a small business, these are the exact tasks the founder or the office manager is already doing by hand between other work.

HR Assistant / HR Coordinator

HR Assistants and Coordinators handle the administrative backbone of HR: scheduling interviews, processing new hire paperwork, maintaining employee files, updating the human resources information system (HRIS), coordinating benefits enrollment, and responding to routine employee questions. They are the first point of contact for employees with HR inquiries and the people who ensure the day-to-day machinery runs.

In a small business, that work looks like filing I-9s, updating the employee spreadsheet, sending onboarding documents, and answering questions about PTO policy.

Recruiting Coordinator

Recruiting Coordinators manage the logistics of hiring: posting jobs, scheduling interviews, coordinating between candidates and hiring managers, and tracking applicants through the pipeline. At companies with steady hiring volume, this becomes a dedicated role. At a small business, recruiting coordination is part of the generalist or founder role.

Mid-Level HR Roles

Mid-level HR roles are where judgment enters the job. A generalist, a specialist, or a business partner decides things rather than processing them, and one of the three is almost always the first HR hire a growing business makes.

HR Generalist

The HR Generalist is the most common first HR hire for growing businesses. Generalists handle a broad range of HR functions: onboarding, employee relations, compliance, benefits coordination, basic recruiting, and policy management. They do not specialize in one area. They cover all of those functions at a level appropriate for a company that does not yet need specialists.

For most small businesses making a first HR hire, the generalist is the right choice. At that point, the volume of work in any single HR function (recruiting, learning and development, compensation) does not justify a dedicated specialist. The business needs someone who can handle an I-9 audit, mediate a workplace conflict, coordinate benefits enrollment, and run onboarding, all in the same week.

HR Specialist

HR Specialists focus deeply on a single function: recruiting (Talent Acquisition Specialist), compensation (Compensation Analyst), learning and development (L&D Specialist), HRIS (HRIS Analyst), or employee relations (Employee Relations Specialist). They bring deeper expertise than a generalist in their specific domain but do not cover the full range of HR work.

Specialists make sense when the volume in a single function justifies dedicated attention. A company hiring 30+ people per year may need a full-time recruiter. A company with complex compensation structures across multiple states may need a compensation analyst. For most small businesses, the generalist model works. Specialists are added as the HR team grows to three or more people.

HR Business Partner (HRBP)

The HRBP partners with business leaders to align people strategy with business goals. Unlike generalists (who execute processes) or specialists (who go deep in one area), HRBPs advise managers on organizational design, workforce planning, talent development, and change management. You will typically find the role at enterprise companies, where business units are large enough to warrant dedicated HR support.

Senior HR Roles

Senior HR roles carry the function itself, not the tasks inside it. From this level up, the job is policy, budget, and the employment law exposure the company is running, and the person is accountable to leadership for all three.

HR Manager

HR Managers oversee the HR function and typically manage a small team of generalists, coordinators, or specialists. They set policies, ensure compliance, handle complex employee situations (terminations, investigations, accommodation requests), and serve as the primary HR point of contact for company leadership. At mid-size companies, the HR Manager is often the most senior HR role.

HR Director / Director of People Operations

HR Directors set the strategic direction for HR and manage HR Managers or functional leads beneath them. They are responsible for workforce planning, compensation strategy, talent development programs, and HR budgeting. This role typically exists at mid-size and larger companies where the HR function has grown beyond a single manager.

Day to day, those responsibilities land in four buckets: the annual headcount and compensation plan, the performance and promotion cycle, the employment law exposure the company is carrying, and the HR systems and vendor contracts everything else runs on. A director carries all four at once and reports on them to the executive team.

The line between an HR Director and an HR Manager is ownership rather than seniority. The manager runs the HR calendar and handles whatever lands in it. The director sets that calendar, defends the headcount and compensation budget to the CEO, and answers for the result when a hiring or retention target is missed.

Executive HR Roles

Executive HR roles exist to put people strategy in front of the people who set company strategy. What separates them from a director is not the scope of the work but who they answer to: the CEO and the board, rather than another functional leader.

VP People / VP Human Resources

The VP People is the most senior HR leader below the C-suite. They own the HR function end-to-end, report to the CEO or CPO, and make strategic decisions about talent, culture, compensation, and organizational development. At many mid-size companies, the VP People is the top HR role.

Chief People Officer (CPO) / CHRO

The CPO or CHRO sits in the C-suite, reports to the CEO, and represents people strategy at the board level. The role covers talent strategy, culture, compensation, organizational design, people analytics, and executive development. CPO signals an employee-experience orientation. CHRO signals a compliance-and-operations orientation. In practice, the responsibilities overlap significantly. This role typically exists at enterprise companies.

HR Generalist vs HR Specialist: Which Does Your Company Need?

A small business needs a generalist. The specialist question only arrives once the volume inside one function (recruiting, compensation, or learning and development) is enough to keep someone busy full time, which in practice means an HR team of three or more.

When a small business is ready for its first HR hire, hire a generalist. Before that point, HR software plus a fractional consultant covers most of the same ground for less.

On cost alone, the comparison is lopsided. A generalist sits in the BLS human resources specialists classification at a $75,940 median, and BLS Employer Costs for Employee Compensation puts private-industry benefits at about 43 percent on top of wages (June 2026).

HR software runs $1,176 to $2,376 a year at FirstHR list pricing. Fractional consulting is billed by the hour, and published rates vary too widely to quote.

Software plus a consultant holds up until the workload is steady enough to keep a full-time generalist busy, and it does so without carrying a salary. But cost is only half the decision. The other half is whether the judgment work has become frequent enough to need someone on site every day.

HR Roles by Company Size

The HR roles a business needs grow with it. At a small business, the founder handles HR with software support until a generalist becomes the first HR hire. A mid-size company runs it through an HR Manager and a coordinator with specialized tools, and at enterprise scale a VP People oversees a team of specialists, HRBPs, and managers.

The functions themselves are the same at every size. Onboarding, compliance, employee records, and offboarding happen in a two-person shop and in a global company alike. What changes from one stage to the next is who handles them and how.

When to Make Your First HR Hire

The question is not "at what headcount do I need HR?" but "is the current setup causing problems?" Four signals indicate the founder can no longer manage HR alone.

Before the first hire, the combination of HR software and a fractional HR consultant covers most needs. FirstHR handles the operational layer: onboarding workflows, e-signature, employee database, document management, training delivery, and org chart. A fractional consultant handles the strategic and sensitive work: termination guidance, accommodation requests, policy development, and compensation benchmarking. Together, they cover the scope of an HR generalist without carrying a full-time salary.

What to Look for in an HR Professional

When you do hire, weigh the shape of the experience first and the credentials second. An HR professional who has run onboarding, an I-9 audit, and a termination at a company your size will be useful within a month. Someone who owned one slice of a large HR department may never have carried any of the three end to end.

How much a certification says about real experience depends on which one a candidate holds. According to SHRM certification eligibility criteria, the SHRM-CP requires no degree and no previous HR experience to apply, while the SHRM-SCP expects at least three years of strategic-level HR work at 1,000 hours or more a year.

The PHR and SPHR come from HRCI, a separate body, and gate on years of professional-level HR experience instead. HRCI asks PHR candidates for one year with a master's degree, two with a bachelor's, or four with neither, and SPHR candidates for four, five, or seven years on the same scale.

On a resume, then, a SHRM-CP tells you someone passed an operational exam, while a PHR tells you someone has been paid to do HR for a defined number of years.

No credential substitutes for asking what someone has handled alone. In a business with no HR department, your first hire has nobody to escalate to, so the question that predicts success is plain: which of the three did you own from start to finish, and what went wrong when you did?

What HR Software Replaces (and What It Does Not)

HR software does not replace HR people. It replaces the administrative and process-driven tasks that fill much of the week for HR professionals, freeing them (or the founder acting as HR) to focus on the work that requires human judgment.

According to SHRM (2016), 60 percent of 1,030 HR and non-HR business leaders surveyed in October 2015 said HR spends more time on administrative and maintenance tasks than on strategic ones. That administrative layer is what a system takes over. The strategic part is judgment work, and at small business scale it comes up infrequently enough that a fractional consultant or the owner covers it.

The automatable layer is not the low-value layer. Research reported by SHRM (2017) found that up to 20 percent of employee turnover occurs within the first 45 days of employment, so the onboarding steps a system can run sit directly on the metric that matters most.

The labor market is already pricing this in. Bureau of Labor Statistics employment projections for 2025 to 2035 put human resources specialist employment on track to grow 6 percent, faster than the average across all occupations, and human resources managers at the same 6 percent.

Human resources assistants, the classification that covers the administrative work, are projected to decline over those same ten years. The administrative layer is shrinking. The judgment layer is not. For a small business, the practical move follows: let software carry the administrative work now, and hire when the judgment work needs someone every day.
