6 templates by level for the firms that hire auditors as staff: staff, senior, manager, IT, government, and a general CPA-firm version, with the independence, CPA, and standards detail generic templates skip. Download as DOCX.
An external auditor independently examines a company's financial statements and issues an opinion on whether they are accurate and conform with accounting standards. The defining feature of the role is independence: the auditor is engaged by a company's board or shareholders, employed by a separate CPA firm, and kept structurally apart from the company being audited. That independence is what makes the role valuable, and it is also what makes hiring one different from hiring almost any other position.
The employer who actually hires an external auditor as an employee is a public accounting or CPA firm, because audit and assurance is the firm's product. The six templates below are built for that firm, by level: staff or associate, senior, manager, IT, government, and a general CPA-firm version. Each leads with the independence, CPA credentials, and professional standards that generic templates skip. For the fundamentals behind any posting, the guide to writing a job description is a useful companion.
TL;DR
An external auditor independently examines financial statements and issues an opinion, engaged by a company's board, employed by a CPA firm. The role is defined by independence, strengthened for public companies by the Sarbanes-Oxley Act and SEC rules. Key point: if you are the company being audited, you engage a firm, you do not hire an employee; the firms that hire auditors as staff are public accounting firms. BLS reports a median of $81,680 for accountants and auditors (May 2024). Download six templates by level as DOCX.
What an External Auditor Does
An external auditor independently examines financial statements and issues an opinion on their accuracy and conformance with accounting standards. The work is structured assurance: planning the audit, testing transactions, balances, and controls, documenting evidence in workpapers, and reporting findings, all under Generally Accepted Auditing Standards.
What sets the role apart is independence. The external auditor is engaged by the board or shareholders and is not part of company management, so the opinion can be trusted by outside parties. That independence shapes the duties, the credentials, and even who can hire the role. For scoping any role before posting, the guide to defining job responsibilities walks through the process.
External vs Internal Auditor
These two titles are often confused, but they are different roles with different hiring paths. The difference matters before you write a posting, because it determines whether you are hiring an employee at all.
Who employs them
External: A CPA firm or self-employed; engaged by the client's board or shareholders
Internal: The company itself, as a regular employee
Independence
External: Independent third party; required by law for public companies
Internal: Reports inside the organization, often to the audit committee
What they audit
External: Financial statements, for an independent opinion to outside parties
Internal: Internal controls, risk, and processes, for management
When you hire one
External: You engage a CPA firm as a vendor; you do not onboard an employee
Internal: You hire and onboard an employee onto your team
Who hires them as staff
External: Public accounting and CPA firms (this is their core staff)
Internal: Mid-size and larger companies with an internal audit function
Engage a Firm, or Hire an Employee?
If you are the company that needs an audit, an external auditor is not a role you onboard. You engage a CPA firm as a vendor, and independence requires that separation. If you want someone in-house reviewing controls and risk on an ongoing basis, that is an internal auditor, a different role you hire as an employee. The templates here are for the firms that hire external auditors as their own staff. This is general information, not legal advice.

Independence, CPA, and Standards
These four points define a serious external auditor posting and are what generic templates leave out: the independence that is the legal core of the role, the limits on what the firm can do for an audit client, the CPA and specialty credentials, and the professional standards the work follows.
Independence is the legal core of the role
What makes an external auditor an external auditor is independence. For public companies, the Sarbanes-Oxley Act of 2002 strengthened external auditor independence, and the Securities and Exchange Commission's rules require that the auditor be genuinely independent of the company it audits. An external auditor is engaged by the client's board or audit committee, not hired into management, precisely so the opinion carries weight with investors, lenders, and regulators. When a firm writes an external auditor job description, independence is not a nice-to-have line; it is the defining feature of the job and should be stated plainly. This is general information, not legal advice.
The auditor cannot also run the client's books or HR
Independence rules limit what an audit firm can do for an audit client. Under the SEC's auditor-independence rules, a firm that audits a public company generally cannot, at the same time, provide that client services like bookkeeping, financial-system design, internal-audit outsourcing, or management and human-resources functions, because doing so would have the auditor reviewing its own work or acting as management. This is why an external auditor is structurally separate from the company's own staff and systems. A firm hiring auditors should build this separation into how it staffs and rotates engagements. This is general information, not legal advice.
CPA licensure and credentials anchor the qualifications
External audit is a credentialed profession. The audit opinion on a public company's financial statements is signed by a licensed CPA firm, and career progression runs from CPA-eligible staff through licensed senior, manager, and partner. Specialized tracks add their own credentials: CISA for IT audit, CIA for internal-audit-adjacent work, CGFM for government auditing. When writing the job description, scale the credential requirement to the level: CPA eligibility and 150 credit hours for staff, an active CPA for managers and above, and the relevant specialty certification for IT or government audit roles. This is general information, not legal advice.
Standards define the work, not just the title
External audit work is governed by professional standards, and naming them signals a serious posting. Audits follow Generally Accepted Auditing Standards, financial statements are evaluated against Generally Accepted Accounting Principles, public-company audits fall under PCAOB standards, and government audits follow the Yellow Book. A strong external auditor job description references the standards relevant to the engagements the role will serve, rather than listing only generic duties. This tells qualified candidates the work is real assurance work and helps the firm attract auditors who already know the frameworks. This is general information, not legal advice.
Independence Is Required by Law
For public companies, the Securities and Exchange Commission's auditor-independence rules, adopted under the Sarbanes-Oxley Act of 2002, require external auditors to be independent of the companies they audit and generally prohibit the audit firm from also providing that client bookkeeping, internal-audit outsourcing, or management and human-resources services. Independence is the legal foundation of the role.
Duties and Skills
External audit duties cluster into four areas: audit fieldwork, documentation, standards and independence, and client and team work. A strong job description picks the responsibilities from each area that match the level, rather than listing every possible task.
Audit fieldwork
Test transactions, balances, and controls
Gather and document audit evidence
Perform risk-based substantive procedures
Documentation
Prepare clear, supported workpapers
Review staff workpapers (senior and up)
Draft findings and report sections
Standards and independence
Follow GAAS and firm methodology
Apply GAAP and reporting frameworks
Maintain auditor independence
Client and team
Communicate with client management
Supervise and coach staff
Manage engagement budgets and deadlines
Staff auditors weight fieldwork and documentation; seniors add review and supervision; managers add engagement and client ownership. Scale the responsibilities to the level. Keep the posting neutral and inclusive, since the EEOC prohibits job advertisements that show a preference based on a protected characteristic, and the SHRM guide covers the standard sections of a job description.
External Auditor Pay
External auditor pay rises sharply with level and credentials. Use government data for the occupation as a baseline, then set ranges by level and your local market.
Median $81,680 for the Occupation (BLS, May 2024)
External auditors are part of the accountants and auditors occupation, which the U.S. Bureau of Labor Statistics reported had a median annual wage of $81,680 in May 2024, with the lowest 10 percent under $52,780 and the highest 10 percent over $141,420 (U.S. Bureau of Labor Statistics). Employment is projected to grow 5 percent from 2024 to 2034.
Within that occupation, staff auditors start lower while seniors, managers, and partners earn substantially more, and an active CPA lifts pay at every stage. Published aggregator figures for external auditor specifically vary widely by methodology, so the BLS occupation median is the most neutral benchmark. Set ranges by level using government data and national compensation surveys, and include a good-faith range where your state requires it.
Who Actually Hires an External Auditor
This is the question to settle before writing the posting, because the answer determines whether you are hiring an employee at all. The external auditor is hired as staff by accounting firms, and engaged as a vendor by the companies that need an audit. Here is how each side should think about it.
If you run a CPA firm, the external auditor is your core staff hire
The employer who actually hires an external auditor as an employee is a public accounting or CPA firm, because audit and assurance is the firm's product. For that firm, the templates here are built for the real career ladder: staff or associate, senior, manager, plus IT and government specializations and a general CPA-firm version. Pick the level you are hiring, fill in the brackets, and post. The job description should lead with independence, the relevant standards, and CPA or specialty credentials, since those are what qualified auditors look for and what separate a serious assurance posting from a generic one.
If you are the company being audited, you engage a firm, you do not hire an auditor
If you run a business that needs an audit, an external auditor is not a role you hire and onboard. By design, the external auditor is independent of your company: you engage a CPA firm as a vendor, through a proposal and engagement process, and the firm staffs the audit. That separation is the point, and for public companies it is required by law. So if you are searching for an external auditor to bring onto your team, what you most likely need is either a CPA firm to engage for the audit, or, if you want someone in-house reviewing controls and risk, an internal auditor, which is a different role and a different hire.
External and internal auditor are different roles with different hiring paths
The two titles get confused, but they are not interchangeable. An external auditor is independent, employed by a CPA firm, and gives an opinion to outside parties; you engage the firm, you do not employ the auditor. An internal auditor is your own employee, reviewing internal controls and risk for management, and is a genuine hire you onboard, though typically at mid-size and larger companies rather than the smallest. Decide which problem you are solving: an independent opinion for outside parties points to engaging a CPA firm, while ongoing internal assurance points to hiring an internal auditor as staff. Naming the right role first saves a great deal of wasted effort.
Onboarding a new auditor into a firm is repeatable, credential-heavy work
For the CPA firm that does hire auditors, onboarding is a recurring, credential-heavy process: an offer letter, the new hire paperwork, signed independence and confidentiality acknowledgments, CPA or specialty-credential tracking, and methodology and software training before the first engagement. FirstHR fits this people side for a public accounting firm: e-signature for the offer letter and independence acknowledgments, document management for signed forms and credential records, training modules for firm methodology and standards onboarding, and task workflows for a first-engagement ramp. To be clear about scope, FirstHR is an onboarding and HR platform, not an audit, accounting, or assurance tool, and it does not run payroll or administer benefits, so pair it with those providers. Applicant tracking is coming soon.
From Hiring to Onboarding
For the CPA firm that hires auditors, the job description is step one. Once a candidate accepts, the same details flow into the offer, the independence acknowledgments, and a credential-heavy onboarding. Because audit hiring is recurring and standards-driven, a repeatable process pays off every busy-season ramp.
Send the offer and acknowledgments
Send the offer letter and collect signed independence and confidentiality acknowledgments, which matter more for audit roles than almost any other.
Collect paperwork and credentials
Complete the new hire paperwork and record CPA eligibility or license, plus any CISA, CIA, or CGFM credential the role requires.
Train on methodology and standards
Assign firm audit methodology, software, and standards training, with signed completion records, before the first engagement.
Ramp on a first engagement
Pair the new auditor with a senior on a first engagement, and keep signed acknowledgments and training records organized.
Once your offer is ready, the offer letter template handles the terms, and an onboarding template structures the new auditor's first weeks, alongside the usual new hire paperwork. FirstHR connects the offer, independence acknowledgments, paperwork, e-signatures, credential records, training, and onboarding workflow in one place so a public accounting firm can manage the full process from one system. FirstHR is an onboarding and HR platform, not an audit, accounting, or assurance tool, and it does not run payroll or administer benefits, so connect those separately. Applicant tracking is coming soon to FirstHR.

Frequently Asked Questions
What does an external auditor do?
An external auditor independently examines a company's financial statements and issues an opinion on whether they are accurate and conform with applicable accounting standards. Day to day, that means planning the audit, testing transactions, balances, and internal controls, gathering and documenting audit evidence in workpapers, evaluating risk, and reporting findings. The defining feature is independence: an external auditor is engaged by the company's board or shareholders, not hired into management, so the opinion carries weight with investors, lenders, and regulators. External auditors work for CPA or public accounting firms, or are self-employed, and follow Generally Accepted Auditing Standards. Their opinion is what outside parties rely on to trust a set of financial statements, which is why the role is structurally separate from the company being audited.
What is the difference between an external and an internal auditor?
The core difference is independence and who employs them. An external auditor is an independent third party, employed by a CPA firm or self-employed, engaged by a company's board or shareholders to give an opinion on financial statements for outside parties. An internal auditor is an employee of the company, reviewing internal controls, risk, and processes for management and the audit committee. You engage a CPA firm to provide an external auditor; you hire and onboard an internal auditor onto your own team. External audit is required by law for public companies and is performed by the firm's own staff, while internal audit is an in-house function more common at mid-size and larger organizations. If you are deciding which to bring in, an independent opinion for outside parties means engaging an external audit firm, while ongoing internal assurance means hiring an internal auditor.
Is an external auditor an employee or a contractor?
From the perspective of the company being audited, an external auditor is neither an employee nor a contractor of that company. The external auditor is independent: employed by a separate CPA or public accounting firm, or self-employed, and engaged by the company's board or shareholders to provide an independent opinion. For public companies, this independence is required by law, and the audit firm generally cannot also provide the client services like bookkeeping or management functions. So a company does not hire and onboard an external auditor the way it would an employee; it engages an audit firm as a vendor through a proposal and engagement process. From the perspective of the CPA firm, however, the external auditor is very much an employee, hired and onboarded onto the firm's assurance staff. This is general information, not legal advice.
Does a small business need to hire an external auditor?
Usually not as an employee, and often not at all. Most small private companies are not legally required to have an external audit, though one may be requested by a lender, an investor, or a buyer. When a small business does need an audit, it engages a CPA firm as a vendor rather than hiring an external auditor onto its staff, because independence requires that separation. If what a small business actually wants is someone in-house reviewing its finances, controls, or compliance on an ongoing basis, that is an internal role, such as an accountant, controller, or internal auditor, not an external auditor. Decide whether you need an independent opinion for an outside party, which points to engaging a CPA firm, or ongoing internal oversight, which points to an in-house hire. This is general information, not legal advice.
What qualifications does an external auditor need?
External auditors need an accounting background and, as they advance, CPA licensure. Entry-level staff auditors typically hold a bachelor's degree in accounting and are CPA-eligible, meaning they have or are completing the 150 credit hours required to sit for the CPA exam. Senior auditors are often CPAs or active candidates, and audit managers and partners hold an active CPA license, since the audit opinion on a public company is signed by a licensed CPA firm. Specialized roles add their own credentials: a CISA for IT audit, a CIA for internal-audit-adjacent work, and a CGFM for government auditing. Beyond credentials, external auditors need strong analytical skills, attention to detail, knowledge of GAAP and GAAS, proficiency with audit software, and the professional skepticism and integrity the role demands. Scale the credential requirement to the level you are hiring.
Why is independence so important for external auditors?
Independence is what gives an external audit its value. The whole point of an external audit is that an objective third party, with no stake in the outcome, vouches for the financial statements, so investors, lenders, and regulators can trust them. If the auditor were an employee of the company or were also running its books, the opinion would be worthless. After major accounting scandals, the Sarbanes-Oxley Act of 2002 strengthened external auditor independence, and the Securities and Exchange Commission's rules require auditors of public companies to be genuinely independent and generally prohibit the audit firm from also providing the client services like bookkeeping, internal-audit outsourcing, or management functions. That is why an external auditor is engaged by the board, kept separate from management, and rotated periodically. Independence is not a formality; it is the foundation of the role. This is general information, not legal advice.
How much does an external auditor make?
External auditors are part of the accountants and auditors occupation, which the U.S. Bureau of Labor Statistics reported had a median annual wage of $81,680 in May 2024, with the lowest 10 percent under $52,780 and the highest 10 percent over $141,420. Pay rises sharply with level and credentials: staff auditors start lower, often in the mid-$50,000s to $70,000s at public firms, while seniors, managers, and partners earn substantially more, and an active CPA license lifts pay at every stage. Specialization in IT or a busy market also raises compensation. Because published aggregator figures for external auditor specifically vary widely by methodology, the BLS occupation median is the most neutral benchmark, and a firm should set ranges by level and local market. Include a good-faith range where your state requires it. This is general information, not legal advice.
What should an external auditor job description include?
A strong external auditor job description names the level up front, whether staff, senior, manager, IT, or government, and includes a short firm summary, a job summary that makes the independent assurance focus clear, and responsibilities grouped into audit fieldwork, documentation, standards and independence, and client and team work. The qualifications should scale the CPA or specialty credential to the level and name the relevant standards, such as GAAP, GAAS, PCAOB, or the Yellow Book. The details that signal a serious posting and that generic templates skip are independence expectations, the specific credentials, and the standards the engagements follow. Close with the compensation, an equal opportunity statement, and clear apply instructions. Pick the matching template, fill in the brackets, and post. This is general information, not legal advice.
