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
Hire against your retrieval failure modes
A RAG engineer connects your source material to useful answers. Start the brief with the documents, access rules, languages, update frequency and failure cases. A legal-document search, an internal knowledge assistant and customer-support retrieval can require different relevance tests and operational controls.
Our screening focuses on how a candidate diagnoses a retrieval problem. Can they separate missing context from poor generation? Explain a change to chunking, filtering or reranking? Design a useful evaluation set and measure whether a change helped? We also examine how source updates and deletions reach the retrieval system.
For sensitive UK customer documents, define the allowed development workflow before sharing material. A candidate should be able to discuss permission-aware retrieval, logging and data minimisation, while your data-protection and security owners approve the actual access model. Technical screening does not certify the system’s legal compliance.
Ask for a walkthrough of one relevant system, the candidate’s own contribution and the limits of the evidence. A redacted diagram or a practical exercise can serve where previous work is confidential. If most of your roadmap concerns broader LLM application delivery, compare the UK LLM engineer role; use evals engineers when measurement is the main missing capability.
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.

| Seniority | UK employee salary | CEE contractor budget | 18% of CEE contract budget | 22% of UK salary (example) | Illustrative fee difference |
|---|---|---|---|---|---|
| Mid-level | £80–100K | £45–58K | £8.1–10.44K | £17.6–22K | £9.5–11.56K |
| Senior | £110–140K | £58–78K | £10.44–14.04K | £24.2–30.8K | £13.76–16.76K |
| Staff / RAG platform lead | £145–175K | £80–105K | £14.4–18.9K | £31.9–38.5K | £17.5–19.6K |
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 £110–140K UK employee base salary or £58–78K 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.

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 for an established retrieval pipeline, senior for end-to-end retrieval quality, or staff for a search platform used by several products. Match scope to demonstrated responsibility.
Remote setup
Confirm core UK collaboration hours and the environments available for corpus inspection and debugging. Record document-access restrictions and whether work can use synthetic or redacted examples before interviewing.
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.
