UK engineering hire
Hire AI evals engineers for UK teams.
Build evidence for your AI release decisions. We source engineers who can design meaningful tests, investigate failures and explain what an evaluation result does—and does not—show.
Standard recruitment
Your search at a glance
Standard: 18% of first-year salary. $2,000 is paid at launch and credited toward that total; the balance is due when your hire starts. We agree the salary basis and search scope before payment.

- Seniority
- Mid-level · Senior · Staff / Eval Lead
- Compensation guide
- £66–88K indicative annual CEE contractor budget for senior.
- Search markets
- CEE candidates for UK teams; working-hour overlap and work location agreed in your brief.
Compensation is indicative. We agree the salary band, locations and working-hour overlap before search; the placement fee is separate.
Focus your engineers’ interview time
We assess technical and soft skills before introducing candidates, so your engineers meet people who have passed the agreed requirements. Review the evidence, run your own technical and team interviews, and choose who to hire. We support coordination and the offer process.
UK-specific hiring context
Choose an evals engineer for the decisions you need to make
Hire an evals engineer when your team cannot reliably explain whether an AI change improved the product. Define the decision first: choosing a model, deciding whether to release, comparing agent behaviour, or investigating failures in a customer workflow. The evaluation should answer that question with evidence your team can interpret.
Screen for dataset construction, coverage of relevant failure modes, scorer validation, repeatability and clear reporting of uncertainty. A strong candidate can explain why an aggregate score may hide a serious regression and how they would investigate it. Where fairness matters to the use case, agree the populations, outcomes and appropriate review with the responsible specialists.
For teams using Inspect, include a task that covers datasets, execution and scoring. Equivalent experience can be relevant when the brief allows it. Public contributions, a particular university or familiarity with one library should not replace an assessment of the work the candidate will actually do.
In a regulated UK organisation, separate engineering delivery from governance ownership. The engineer can implement evaluations and produce evidence; your firm decides which obligations apply and who independently reviews the results. If you mainly need someone to build the product feature itself, compare LLM engineers or AI/ML engineers.
Across Recruo searches
Our recruitment results so far
Company-wide observations reported by Recruo’s founder on 11 September 2026. These describe our overall experience, rather than a separate cohort for this role or region.
- Pass every client assessment stage
≈9/10
Presented candidates who successfully pass the client’s full assessment process, including technical interviews.
- Candidates the client would offer to
≈4/5
Client willingness to make an offer after assessment. Offers sent, accepted and hires are separate outcomes.
- Completed probation periods passed
100%
All placed candidates whose probation has concluded have passed so far. Ongoing probation periods are excluded.
How to read these results
Pass every client assessment stage: Candidates who pass all client assessment stages, relative to candidates presented. Around 9 in 10 is an approximate company-wide observation, not a published sample of exactly ten people. Offers, acceptance and starts are separate outcomes; sample size, reporting period and treatment of ongoing assessments are not yet published.
Candidates the client would offer to: Presented candidates the client considers suitable for an offer, divided by candidates presented. Around 4 in 5 describes willingness to offer; it does not mean four offers or hires for every five candidates.
Completed probation periods passed: Placed candidates who passed probation, divided by placements whose probation period has ended. Probation lengths vary by engagement; this is not a 90-day retention measure or a guarantee of future outcomes.
Sample sizes and the reporting period are not yet published. The candidate ratios are approximate; none of these results is a forecast for your vacancy.
Plan your hiring budget
Indicative planning ranges: annual UK employee base salary and annual CEE contractor budget. Confirm the location, scope and engagement model before comparing total costs.

| Seniority | UK employee salary | CEE contractor budget | 18% of CEE contract budget | 22% of UK salary (example) | Illustrative fee difference |
|---|---|---|---|---|---|
| Mid-level | £90–115K | £52–68K | £9.36–12.24K | £19.8–25.3K | £10.44–13.06K |
| Senior | £120–150K | £66–88K | £11.88–15.84K | £26.4–33K | £14.52–17.16K |

Total recruitment fee: 18% of the CEE contractor budget shown versus 22% of the UK-local salary shown. $2,000 is paid at launch and credited toward the total; the balance is due when your hire starts. The difference combines two effects: different compensation bases and different fee rates. It is not a like-for-like saving on the same salary. Employer taxes, benefits, EOR costs and other engagement costs are excluded. The comparison agency rate is an assumption, not a market-wide standard. Figures are rounded; the fee difference on the same salary is 4 percentage points.
Budget assumptions
Understand the fee and the engagement budget
Illustrative fee comparison: on the same £100,000 first annual salary, Recruo’s 18% Standard fee is £18,000. A 22% fee would be £22,000, a £4,000 difference. The 22% rate is an illustration, not a claim about the UK market standard or a quote from another agency.
For a senior hire, the table uses £120–150K UK employee base salary or £66–88K annual CEE B2B contract value. These are Recruo planning estimates, not verified market medians or equivalent total employment costs. Compare employer contributions, benefits, paid leave, equipment, provider charges and any agreed on-call or travel costs separately. The table’s fee difference uses different compensation bases as well as different fee rates; it is not a like-for-like agency saving. Confirm the candidate’s expectations and the fee base in the mandate.
Search timeline
First qualifying finalist: First qualifying finalist by business day 15, or stop for a full $2,000 refund; 60-calendar-day search
Finalists have passed the agreed assessment stages. The 60-calendar-day search begins on the agreed launch date; your team makes the final hiring decision.
What affects the start date
Depends on interview stages, candidate notice and the engagement setup
Final conversations, offer decisions and notice periods affect the hire’s start date.
Recruo service target, with feasibility agreed per brief. No role-specific market median or completed-hire promise is implied.
Visa & work-authorisation patterns
- • Remote engagement: agree the country of work and whether a contractor or local employment arrangement fits the role.
- • Employer of Record: confirm the employing entity, local employment terms and provider fees. This does not automatically mean UK employment or UK payroll.
- • UK-based work or relocation: check right to work and any sponsorship requirements before agreeing onsite commitments.
Level of ownership
Choose mid-level to extend an established harness, senior to own evaluation design, or a lead to coordinate measurement across products and reviewers. Framework familiarity alone does not establish seniority.
Remote setup
Agree UK collaboration hours for engineering and review sessions. Establish access to evaluation datasets, handling of sensitive examples and who signs off changes to scoring or release criteria.
Contracting and candidate data: what to agree before search
UK contracting review
UK contracting needs an engagement-specific assessment.
Work location, UK tax and National Insurance liability, and the actual working arrangement matter. Overseas business registration alone does not settle the question. Review B2B or EOR terms with your adviser using HMRC international guidance and CEST where applicable.
Privacy and human oversight
Human-in-the-loop by design, not as an afterthought.
A human recruiter reviews the shortlist and its supporting evidence before handoff. Confirm the data-processing roles, candidate notices, hosting, retention and transfer terms for your engagement. Human review supports oversight; it does not certify the entire hiring process.
