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. The titles, responsibilities, and salary ranges differ significantly across each level, and which roles a company actually needs depends primarily on its size. 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, the 7 core functions these roles support, salary benchmarks, the generalist vs specialist question, and the part most guides skip entirely: which HR roles your business actually needs at each stage of growth, and which ones can be handled by software instead.

The 7 Core Functions of HR

Every HR role exists to support one or more of these seven functions. Understanding the functions first makes the roles make sense, 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. The functions exist regardless of company size. The question is how they are staffed.

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 that actually cover 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.

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 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.

At a small business, these tasks are exactly what the founder or office manager is doing manually. Filing I-9s, updating the employee spreadsheet, sending onboarding documents, 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 them at a level appropriate for a company that does not yet need specialists.

The generalist role is the right hire for most small businesses making a first HR hire. At that point, the volume of work in any single HR function (recruiting, L&D, 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. This role typically exists 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 misses.

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 or 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.

The arithmetic settles it. A generalist sits in the BLS human resources specialists classification at a $75,940 median, and BLS Employer Costs for Employee Compensation puts benefits at roughly 40 percent on top of wages. 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.

Until the workload is steady enough to keep a full-time generalist busy, that combination covers the same scope without carrying a salary. The question is not which is cheaper in the abstract. It is whether the judgment work has become frequent enough to need someone on site every day.

HR Roles by Company Size

This is the section most HR role guides skip, but it is the most practical question for a growing business: which roles do you actually need at your size?

The key insight: the functions 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 is who handles them and how. At a small business, the founder handles it with software support. At a mid-size company, an HR Manager and a coordinator handle it with specialized tools. At enterprise scale, a VP People oversees a team of specialists, HRBPs, and managers.

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, compliance tracking, 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.

Certifications tell you what kind of work a candidate has been doing. 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: one year with a master's degree, two with a bachelor's, and four with neither. So 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 these 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 HR people spend most of their time on, freeing them (or the founder acting as HR) to focus on the work that requires human judgment.

According to SHRM, 60 percent of HR professionals spend their time on administrative and maintenance tasks and the rest on HR practices and policies. That administrative layer is what a system takes over. The rest is judgment work, and at small business scale it comes up infrequently enough that a fractional consultant or the owner covers it.

The automatable half is not the low-value half. Up to 20 percent of all employee turnover happens in the first 45 days, according to SHRM, so the onboarding functions a system can run end to end sit directly on the metric that matters most.

The labor market is already pricing this in. Bureau of Labor Statistics employment projections for 2024 to 2034 put human resources specialist employment on track to grow 6 percent, faster than the average across all occupations, and human resources managers in the same band. 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.
