AI Job Descriptions: Write Them Fast, Check Them for Bias
TL;DR
- What it is: An AI job description is a job post drafted by AI — fast to produce, and only as fair as the check you run on it.
- Who it's for: Anyone writing job posts without a recruiting team — see the Recruiting & Hiring Skills Pack.
- How it works: Draft around the real must-haves, then run a bias check that flags loaded language — age cues, gendered terms, coded "culture fit" — and rewrites it with an explanation.
- Bottom line: A generic AI draft ships the same biased phrasing it learned from a million old job ads. The bias check is the step that makes AI worth using.
This is general information for employers using AI in hiring, current as of August 2026. It is not legal advice, does not create an attorney-client relationship, and does not assess whether any particular hiring practice is lawful. Employment law varies by federal, state and local jurisdiction and has changed materially more than once in the last two years. Confirm your obligations with qualified employment counsel before adopting or changing a hiring process.
How do you write a good AI job description?
Give the AI the role's real must-haves (not a wish list), have it draft a clear, structured post, and then run a bias check on the draft: flag loaded language like age cues, gendered terms, coded "culture fit," and inflated requirement lists, and rewrite each one inclusively with a short explanation of what was flagged. A human approves the final text, and anything legal-adjacent goes past HR or counsel. The bias check is what separates an AI job description that widens your pool from one that quietly screens people out.
Best for: founders and managers who write their own job posts — the Recruiting & Hiring Skills Pack ships a job-description writer with this bias check built in.
The job post is the first screen in your hiring process — it filters people before a single résumé arrives. That's why an AI job description is both the easiest win and the easiest mistake. Paste "write a job description for a marketing manager" into a chatbot and you get a polished post in ten seconds. You also get everything the model learned from decades of job ads: the age cues, the gendered verbs, the "culture fit" code, the requirement list nobody on earth fully meets. Faster, yes. Better, no. This is the first stage of the process we map in AI for recruiting and hiring.
The language that screens people out
Most biased job-post language isn't malicious. It's inherited — copied from the last post, which was copied from the one before. That's exactly why an explicit check matters: nobody is choosing these phrases, so nobody is catching them either.
| Pattern | Example phrasing | Why it's a problem | Better direction |
|---|---|---|---|
| Age cues | "Young and energetic," "digital native," "recent grad" | Signals an age preference — commonly risky under age-discrimination law | Describe the work: "comfortable in a fast-changing toolset" |
| Gendered language | "Rockstar," "ninja," "he will manage…" | Research on job-ad wording suggests coded terms narrow who applies | Plain role language: "you will manage…" |
| Coded "culture fit" | "Work hard, play hard," "like a family" | Vague fit language invites bias in, because anyone can fail it for any reason | Name actual working norms: hours, feedback style, remote setup |
| Inflated requirements | "10+ years, MBA preferred, expert in 9 tools" | The wish list reads as exclusionary — strong candidates self-select out | 3–5 true must-haves; move the rest to "nice to have" or cut |
| Unneeded physical terms | "Must be able to lift 50 lbs" (for a desk job) | Requirements not tied to the real job raise disability-discrimination risk | Only list physical requirements the job genuinely demands |
Not legal advice: these patterns are commonly flagged as risky, but employment law varies by country, state, and city and changes over time. Many states and cities also restrict asking about criminal history until later in the process (ban-the-box), or asking salary history at all — verify local rules before you screen or make an offer. Treat every flag as a prompt to check with HR or counsel — not as legal clearance either way.
Must-haves first, or the AI drafts a wish list
The single biggest input decision is separating must-haves from nice-to-haves before the AI writes a word. Give a model a vague role name and it pads the requirements section with everything plausible — and every padded requirement shrinks your pool. Studies of applicant behavior have long suggested that many qualified candidates, and disproportionately women, skip roles where they don't meet the full stated list. The inflated list doesn't protect quality. It filters for confidence.
A good AI workflow pushes back here. When RedHub's job-description-writer skill gets a wish list, it asks which items are genuinely required to do the job in the first year — and structures the post around those. That question, asked every time, is worth more than any phrasing polish.
The workflow: draft, check, explain, approve
- Define 3–5 real must-haves. If a requirement wouldn't disqualify an otherwise-great candidate, it's not a must-have.
- Have AI draft the post — structured around must-haves, responsibilities, team context, and pay transparency where appropriate or required.
- Run the bias check as a separate, named pass. Flag age cues, gendered terms, coded fit language, inflated lists, and unneeded requirements.
- Read the explanations. A good check names what was loaded about each phrase and why. Silent rewrites teach you nothing — the explanation is where your team learns.
- Human approves; HR or counsel reviews anything legal-adjacent. The AI drafted and checked. You decide what ships.
Notice what's missing from that list: nowhere does the AI decide anything about a person. The job post shapes who applies — the decisions about who advances belong to the screening stage, which has its own rules. We cover those in how to use AI to screen candidates fairly.
A JD writer with the bias check built in
The Recruiting & Hiring Skills Pack ($79) includes a job-description-writer skill that drafts around real must-haves, flags loaded language with a one-line explanation per flag, and ships with an inclusive-JD reference covering the patterns to hunt. Plus five more skills for the rest of the hiring lifecycle. Not legal advice — the skill tells you what to have HR or counsel review.

A bias-checked, must-have-first job post pays off past the applications inbox. The must-haves become the screening criteria. The screening criteria become the interview dimensions. The interview dimensions become the scorecard. One clean definition of the role, written at the top, keeps the whole process consistent — which is the theme of the full AI-for-hiring guide. And when the interviews start, the same discipline applies to what you ask: see AI interview questions that are structured, predictive, and flag the risky territory.
Decision Guide
Use an AI job description if: you write your own job posts, you can name the role's real must-haves, and you'll run a bias check and approve the final text yourself.
Skip it if: you want to paste a role title into a chatbot and publish whatever comes back. That ships inherited bias at speed.
Best first step: run your current live job post through a bias check before writing anything new. The flags tell you what your old process was shipping.
FAQ
Can AI write a good job description?
Yes — if you feed it real must-haves and run a bias check on the draft. Without those two steps, AI reproduces the padded, coded job-ad language it learned from, just faster.
What biased language should I check a job post for?
Age cues ("young and energetic," "digital native"), gendered terms ("rockstar," gendered pronouns), coded culture-fit phrasing ("like a family"), inflated requirement lists, and physical requirements the job doesn't genuinely demand.
Is a biased job post illegal?
Some phrasing can create real legal exposure under anti-discrimination law, and the risk varies by jurisdiction. Treat flagged language as something to fix and, where you're unsure, something to run past HR or counsel. This article is not legal advice.
How many requirements should a job post have?
Three to five true must-haves. Everything else is nice-to-have or noise. Long requirement lists shrink your pool and read as exclusionary — they filter for confidence, not competence.
Should the AI rewrite flagged language automatically?
It should rewrite it and explain each flag. Silent rewrites fix one post; explanations teach your team to stop writing the pattern. Either way, a human approves the final text.
Does the Recruiting & Hiring Skills Pack do this?
Yes. Its job-description-writer skill drafts around real must-haves, runs the bias check as a separate named section, explains every flag, and reminds you to have HR or counsel review before you rely on it. It's one of six skills in the $79 pack.
Stop shipping inherited bias at speed
Draft the post fast, catch the loaded language, and know what to send past counsel — with a human approving every word that ships.
