Hire RAG developers
Senior RAG developers design and ship retrieval pipelines end to end, covering chunking strategies, embedding models, vector store configuration and reranking. Every candidate is tested on evaluation design, because an engineer who can't measure retrieval quality can't improve it.
01
Embedding models shifted the retrieval baseline
A few years ago retrieval meant keyword search and BM25 tuning. Engineers now choose between dense, sparse, and hybrid retrieval, and the choice changes meaningfully depending on corpus size and query distribution.
02
Evaluation is now a first-class engineering task
RAG pipelines fail quietly, so engineers who don't instrument recall and faithfulness metrics ship systems that look fine in demos and degrade in production. Writing evals has become as central to the role as writing the pipeline itself.
03
Context-window growth changed chunking decisions
Larger context windows made naive chunking appear to work, so engineers now need sharper intuition about when chunking strategy still matters and when retrieval quality is the actual bottleneck. That judgement comes from experience with real production queries.
How we assess RAG developers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For RAG developers, these criteria carry the most weight.
- Technical understanding
In the fundamentals assessment, engineers explain chunking trade-offs and embedding model selection. Assessors look for decisions grounded in corpus structure and query patterns rather than defaults.
- AI output verification
In the second assessment, with their own agents running, engineers validate generated retrieval code against real query results. RAG engineers who trust model output without checking it ship silent regressions.
- Debugging
Engineers get a broken retrieval pipeline in a real codebase, and assessors watch how they isolate whether the failure is in chunking, embedding, retrieval or the generation step.

What is RAG
RAG connects a language model to an external knowledge source at inference time, so answers draw on retrieved documents rather than training data alone.
What is an eval
An eval is a test that measures how well a language model or AI system performs on a defined task. Teams use evals to check whether a change makes the system better or worse.
What is an AI gateway
An AI gateway is a proxy layer that sits between your application and one or more model APIs, handling routing, auth, rate limits, logging and cost controls.
Questions about hiring RAG developers
How senior are these engineers?
The RAG developers we put forward are senior, with 6+ years' experience on average and production RAG systems they've shipped and maintained. Every one has passed both assessments, and you see their scorecards before you meet them.
How do you test RAG skills specifically?
Both assessments are sixty minutes in a real codebase. In the first assessment, with AI tools off, engineers work through chunking strategy, embedding model trade-offs and debugging a broken retrieval pipeline. In the second assessment, they build and verify pipeline components with their own agents and tools, and you get both scorecards.
How quickly can an engineer start?
You get a shortlist within five working days. From shortlist to first commit takes around three weeks, which covers your interviews, any trial work, and contract setup.
What does a RAG developer cost?
You pay a fixed monthly fee of €5,600 to €8,000 per full-time engineer, with employment, payroll and compliance included and no recruitment fee. The pricing page compares it with the all-in cost of a senior local hire in your country. Engagements are full-time with a three-month minimum, and if a placement doesn't work out, we replace them at our cost.
Do they use our tools or their own?
A full-time RAG developer costs €5,600 to €8,000 a month, with no recruitment fee and nothing upfront. Engagements are full-time with a three-month minimum. If the fit is wrong, we replace the engineer at our cost.
Get a shortlist within five working days
You share the roles and the stack in a short form or a thirty-minute call. Within five working days you get named senior engineers to review, each with both scorecards.
