Write Better Job Descriptions in a Fraction of the Time.
Your consultants know the role inside out, but translating that knowledge into a compelling, compliant job description still takes hours. AI handles the drafting so your team can focus on filling the role.
The Job Description Bottleneck
A good job description is the foundation of every successful placement. It shapes who applies, how many apply, and whether the right people see themselves in the role. Yet writing one properly is surprisingly time-consuming. Optimus Performance estimates that a thorough job description, including discussion with the hiring manager, takes 2 to 3 hours to produce.
That time adds up fast. A consultant handling 15 to 20 vacancies simultaneously cannot afford to spend half a day wordsmithing each posting. The result is often a rushed copy-paste from a previous listing, with outdated requirements and generic language that fails to attract the right candidates. Research from Insight Global found that more than half of job seekers say the quality of a job description directly influences their decision to apply, and job posts that include salary details receive 67% more clicks.
The knock-on effects extend beyond application volume. Poorly written descriptions attract irrelevant applications, and Totaljobs found that 72% of UK recruiters cite irrelevant applications as their biggest barrier to efficiency. Every weak job description creates downstream admin that could have been avoided at source.

How AI Changes the Process
AI drafting does not replace the recruiter who understands the role. It accelerates the translation from briefing notes into a polished, structured listing. The CIPD found that 66% of UK organisations using AI in recruitment reported improved hiring efficiency. For agencies looking to go further, agentic workflows can connect your ATS to an AI drafting pipeline that generates compliant, on-brand descriptions automatically whenever a new vacancy is created.
Brief the AI on the role
Provide the job title, key responsibilities, must-have qualifications, salary range, and any specific requirements from the hiring manager. The more context you give, the stronger the first draft.
Generate a structured draft
The AI produces a complete job description with sections for responsibilities, requirements, benefits, and company overview. It follows best practices for inclusive language and readability.
Review and refine
Your consultant reviews the draft, adjusts the tone to match the client brand, and adds any nuances that only a human who has spoken with the hiring manager would know.
Check for bias and compliance
AI can flag potentially discriminatory language, gendered wording, and unnecessarily restrictive requirements that might exclude qualified candidates. Neutral job descriptions receive 42% more responses.
Publish and iterate
Post the listing and track application quality. Over time, you build a library of high-performing descriptions that the AI can reference for similar roles.

Example Prompt
Role: You are a senior recruitment copywriter specialising in UK job descriptions for agency recruiters. Context: I need a job description for a [job title] role based in [location], paying [salary range]. The client is a [company type/industry]. Key information from the hiring manager: [paste briefing notes or bullet points here]. Task: Write a complete, professional job description that includes: a compelling opening paragraph (no more than 3 sentences), a clear list of responsibilities (6-8 bullet points), essential and desirable requirements (separated clearly), benefits and package details, and a brief company overview paragraph. Use inclusive, gender-neutral language throughout. Flag any requirements that might unnecessarily narrow the candidate pool. Format: Present the job description in a ready-to-post format with clear section headings. After the description, include a short "Suggestions" section noting any requirements that could be broadened and any missing information that would strengthen the listing. Constraints: British English spellings. Do not use superlatives like "world-class" or "rockstar." Keep the total length under 600 words. Ensure compliance with UK employment advertising regulations.

Frequently Asked Questions
Will AI-written job descriptions sound generic?
Only if you give the AI generic input. The quality of the output depends on the quality of your briefing. Provide specific details about the role, team, culture, and client, and the draft will reflect that specificity. Your consultant then adds the final human touch that makes each listing distinctive.
Can AI help with inclusive language in job descriptions?
Yes, and this is one of its strongest applications. Research shows that job descriptions using neutral language receive 42% more responses. AI tools can flag gendered words, unnecessarily restrictive requirements, and jargon that might discourage qualified candidates from applying.
How does this work for niche or technical roles?
AI performs well with technical roles when you provide the right context. Include the hiring manager briefing notes, relevant technical terminology, and examples of previous successful hires. The AI structures and polishes the content; it does not need to understand the technology to write a clear description of it.
Should I still get the hiring manager to review the description?
Absolutely. AI accelerates the drafting, but the hiring manager sign-off remains essential. The difference is that instead of reviewing a rough first draft after three hours of work, they review a polished draft produced in minutes. This often leads to faster approvals and fewer revision cycles.
Do I need specialist software for this?
No. You can start with a general-purpose AI tool like ChatGPT or Claude and the prompt on this page. Specialist recruitment platforms offer additional features such as ATS integration and compliance checking, but the core capability is available for free today.
