AI Job Descriptions: A Proven Way to Attract the Right People

Quick answer: Good AI job descriptions start with your own facts, not the tool: the real tasks, the must-have skills, the pay range, hours and location. Feed those into an AI assistant with clear instructions, then edit the draft for accuracy, plain English and fairness under the Equality Act 2010 before you publish it.

Small businesses rarely have time to craft the perfect advert. The usual result is a hurried list of duties copied from an old post, or a generic template that could describe any job anywhere. Neither attracts the people you want. AI writing assistants can turn rough notes into a clear, well-structured description in minutes, but only if you give them the right material and check what comes back.

Why most job descriptions miss the mark

Candidates skim adverts quickly and decide within moments whether a role is for them. Descriptions fail when they are vague about the work, pile on requirements that are not really needed, bury practical details such as hours and pay, or use jargon that means something only inside the business.

AI tools do not fix this on their own. Left to their defaults, they often produce enthusiastic but empty wording: phrases about exciting environments, rockstars and passion that say nothing specific. The value comes from using AI to organise and polish your own knowledge of the job. For a wider look at where automation helps and hinders recruitment, see our guide to using AI in hiring.

Gather the facts before you open an AI tool

Spend ten minutes on this and the draft will be far better. Write down:

• The purpose of the role in one sentence: why it exists and what would be different if the right person joined.
• A typical week: the five or six tasks that take most of the time.
• Essential requirements: only the skills, licences or experience genuinely needed from day one.
• Desirable extras: things that would help but can be learned.
• Practical details: pay or pay range, hours, shift patterns, location, travel, contract type and start date.
• What you offer: training, progression, flexibility, team size and anything that makes the job worth having.
• How to apply and what happens next.

Be honest about the less appealing parts too. If the role involves early starts or heavy lifting, saying so saves everyone time and reduces early departures.

How to write AI job descriptions step by step

1. Set the context. Tell the assistant you are a small UK business, what you do and who the advert is for.
2. Paste in your facts. Include the notes above. The more specific they are, the more specific the draft will be.
3. Give clear instructions. Ask for British English, plain language, short paragraphs, a clear essential/desirable split, and no clichés or buzzwords.
4. Ask for structure. A summary, what you will do, what you will need, what we offer, and how to apply works well for most roles.
5. Request a fairness check. Ask the assistant to point out wording that might put off particular groups or that sets requirements not linked to the job.
6. Edit by hand. Correct anything inaccurate, remove anything you cannot deliver, and add your own voice.
7. Test it on a colleague. Ask someone who does similar work whether it describes the job they would recognise.

A simple instruction to try: “Using only the facts below, write a job advert for a small UK business in plain British English. Avoid buzzwords. Separate essential and desirable requirements. Flag any requirement that may not be necessary for the role.” The phrase “using only the facts below” matters, because it discourages the tool from inventing benefits or duties.

Useful follow-up requests

The first draft is a starting point. Short follow-up instructions can improve it quickly:

• “Cut this to around half the length without losing any facts.”
• “Rewrite the opening so it explains what the person will actually do in their first month.”
• “List any statements here that are not supported by the facts I gave you.”
• “Suggest a clearer job title that someone searching job boards would use.”
• “Rewrite the requirements as skills rather than years of experience.”

That third request is especially useful, because it asks the tool to audit its own additions. Treat its answer as a prompt for your own check rather than a guarantee.

Tool types and effort

You do not need specialist recruitment software to produce good AI job descriptions. A general AI assistant will do the drafting, and many job boards and applicant tracking systems now include built-in writing helpers. Specialist tools may add features such as bias checking or templates for particular sectors, usually on a subscription. For an occasional hire, a general assistant plus careful editing is normally enough; if you recruit often, a system that stores approved templates can save repeated effort.

Keep your finished descriptions in one folder. Next time you hire for a similar role, give the AI your previous approved version and the changes, rather than starting from scratch. Over time, your AI job descriptions will build into a consistent, recognisable set that reflects how your business actually works.

A worked example: a bakery in Milton Keynes

Imagine a family bakery in Milton Keynes recruiting a part-time counter assistant. The owner’s first attempt says the business wants a “dynamic, customer-focused team player with at least two years’ retail experience and excellent communication skills”.

She lists the real facts instead: early weekend shifts, serving customers, packing online orders, keeping the counter clean and following food hygiene rules. Experience is helpful, but she is happy to train someone reliable. She adds the hours, the pay, the location near the market and the free staff lunch.

The AI draft that comes back is clear and specific, but it adds “must have a food hygiene certificate”, which she had not said. She changes it to “we will provide food hygiene training” and drops the two-year experience requirement, which would have excluded capable school leavers and people returning to work. The final advert is shorter, more honest and attracts applicants who know what the job involves. That is the right way to use AI job descriptions: the tool drafts, the owner decides.

Fairness and the law

Under the Equality Act 2010, adverts must not discriminate on protected characteristics such as age, sex, race, disability, religion or belief, sexual orientation and others. AI tools learn from existing text, and existing adverts contain plenty of biased habits, so check the wording carefully.

• Avoid age-coded phrases such as “recent graduate”, “young team” or “digital native” unless there is a genuine, lawful reason.
• Only list physical requirements that are truly part of the job, and mention that you will consider reasonable adjustments.
• Question requirements for years of experience; describe the skills needed instead.
• Ask for qualifications only where the role genuinely needs them.
• Use gender-neutral job titles and wording.
• Confirm the right to work in the UK is checked for all successful candidates in the same way.

If you use AI later in the process, for example to screen applications, tell candidates, keep a person responsible for decisions and handle their data in line with UK GDPR. Acas offers free, practical guidance on recruitment and discrimination, and a qualified employment adviser can help with anything unusual.

Common mistakes to avoid

• Publishing the first draft. It will sound polished and may still be wrong.
• Letting the tool invent details. Remove any benefit, duty or requirement you did not provide.
• Endless requirement lists. Long lists put off good applicants who do not tick every box.
• Hiding the pay. Clear pay information helps candidates decide quickly.
• Copying a big company’s tone. Your advantage as a small business is being direct and human.
• Pasting in personal data. You do not need names or details of current staff to write a job advert.

Checklist before you publish

• Every fact in the advert is accurate and approved by you.
• Essential and desirable requirements are clearly separated.
• Pay, hours, location and contract type are stated.
• No buzzwords, jargon or internal abbreviations.
• Wording checked for bias and Equality Act issues.
• Reasonable adjustments mentioned.
• Clear instructions on how to apply and what happens next.
• Read aloud once to check it sounds like your business.

Key takeaways

• Strong AI job descriptions depend on specific facts you supply.
• Tell the tool to use only your information and to avoid clichés.
• Edit every draft for accuracy, tone and fairness.
• Cut requirements that are not genuinely needed.
• Keep people in charge of hiring decisions and seek advice when unsure.

AI job descriptions: frequently asked questions

Is it acceptable to use AI job descriptions?

Yes. Many employers use AI to draft adverts. What matters is that the final text is accurate, fair and approved by a person, because the business is responsible for what it publishes.

Will candidates notice the advert was written by AI?

They may notice generic wording, which is why editing matters. A description full of specific detail about the real job reads as genuine, however it was drafted.

Can AI help me decide the right pay?

It can suggest factors to consider, but it may not have reliable, current local pay data. Check the legal minimum wage rules on GOV.UK, look at comparable local adverts and use your own judgement.

How long does it take?

Once your facts are gathered, drafting and editing AI job descriptions usually takes well under an hour, much of it spent on the careful review that makes the advert work.
