Generative AI for Writing Job Descriptions: A Step-by-Step Guide
Job descriptions are one of the first and best uses of generative AI in HR. Done well, AI produces clearer, more inclusive adverts in minutes. Done carelessly, it produces generic copy that attracts no one.
Short answer
To write job descriptions with generative AI, start from a short role brief agreed with the hiring manager, prompt the AI with the role's purpose, responsibilities, genuine requirements and your employer brand, then review the draft for accuracy, inclusive language and legal compliance. AI saves drafting time and can flag exclusionary wording, but the recruiter and hiring manager must confirm every requirement is real.
Key takeaways
- The quality of an AI job description depends on the quality of the role brief you give it.
- Ask the AI to separate must-have from nice-to-have requirements, and challenge inflated criteria.
- Use AI to check drafts for gendered, age-related or exclusionary language.
- Always review for accuracy, pay transparency rules and local employment law.
Why use generative AI for job descriptions
Writing a good job description is harder than it looks. Many are copied from old templates, packed with jargon and inflated requirements, and written for internal approval rather than for candidates. Generative AI helps in three ways: it produces a structured first draft quickly, it can rewrite for clarity and tone, and it can review text for language that might discourage qualified people from applying.
The five-step process
Step 1: Agree a role brief
Before opening any AI tool, spend fifteen minutes with the hiring manager on the essentials: why the role exists, what success looks like after six and twelve months, the three to five outcomes the person will own, the skills genuinely needed on day one, location and working pattern, and the pay range.
Step 2: Prompt the AI with the brief
Act as an experienced recruiter writing for [company], a [description] known for [employer value proposition]. Using the role brief below, write a job description for a [job title]. Include: a two-sentence summary of the role's purpose; 5 to 7 responsibilities written as outcomes; must-have skills (maximum 5); nice-to-have skills; what we offer; and how to apply. Use plain, inclusive language, address the reader as "you", and keep it under 550 words. Role brief: [paste brief]
Step 3: Challenge the requirements
Review the requirements in this job description. Identify any that may be unnecessary barriers for capable candidates, such as degree requirements, years of experience or specific tools that could be learned quickly. For each, explain the risk and suggest a skills-based alternative.
Discuss the suggestions with the hiring manager. This step often widens the talent pool significantly, particularly for skills-based hiring.
Step 4: Check language and compliance
Review this job description for words or phrases that could discourage applicants based on gender, age, disability, ethnicity or caring responsibilities. List each, explain why, and suggest neutral alternatives.
Then check legal requirements yourself. Some jurisdictions require salary ranges in job adverts, and many prohibit age-related language such as "digital native" or "recent graduate" unless justified. AI can prompt you to check, but it is not a substitute for legal knowledge.
Step 5: Finalise and test
Get hiring manager sign-off, publish, and track the results: applicant numbers, quality of shortlist and diversity of the pool. Use these results to improve your prompt for next time.
Quality checklist
| Check | Question to ask |
|---|---|
| Accuracy | Does every responsibility and requirement reflect the real job? |
| Clarity | Would a candidate outside the company understand every sentence? |
| Inclusion | Have exclusionary or coded words been removed? |
| Requirements | Are must-haves genuinely necessary on day one? |
| Compliance | Are pay, location and legal disclosures correct for the jurisdiction? |
| Brand | Does it sound like your organisation, not a generic template? |
| Length | Is it scannable, with the key information near the top? |
Mistakes to avoid
- Prompting with a title only. "Write a job description for a marketing manager" produces generic text.
- Accepting inflated requirements. AI tends to add plausible-sounding requirements. Remove what is not needed.
- Publishing without hiring manager review. Invented responsibilities mislead candidates.
- Losing your voice. Provide examples of your best adverts so the AI matches your style.

How do I make an AI job description more inclusive?
Ask the AI to identify gendered, age-related or exclusionary language and to suggest neutral alternatives, reduce must-have requirements to those genuinely needed, and use plain language addressed to the candidate.
Is there a free AI job description generator?
Most general-purpose AI assistants can generate job descriptions, and many applicant tracking systems include the feature. See free AI tools for recruiters.
Should I tell candidates that a job advert was written with AI?
There is generally no legal requirement to disclose AI-assisted drafting of adverts, but transparency about AI use in selection decisions is increasingly expected and in some places required.
