Hire senior AI engineers for UK teams
Senior AI engineers own the model layer: retrieval pipelines, evaluation frameworks, fine-tuning, serving and production guardrails. Each one is tested on evaluation design, tool orchestration and knowing when a model is the wrong tool entirely. A senior local hire in the United Kingdom takes 4 months on average.
01
The role shifted from research to engineering
Two years ago an AI engineer was mostly doing research. Now they're handling evals, latency, cost and retrieval quality.
02
Production failures are now the real problem
The systems that catch a model failing quietly in production didn't exist two years ago, and building them is core to the role now.
03
Model work and product work are distinct roles
An AI engineer works at the model layer while an AI-native engineer builds product with AI tools, and you hire for them differently.
How we assess AI engineers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For AI engineers, these criteria carry the most weight.
- Evaluation design
An AI engineer who can't design evals can't tell whether a model change made the system better or worse.
- AI output verification
At the model layer, trusting output without verification is how production systems degrade silently over time.
- Tool orchestration
Retrieval pipelines and serving infrastructure involve chaining tools, and poor orchestration shows up immediately in latency and cost.
- Evaluation design
Building the eval that tells you whether a model change made things better or worse, before it ships.
- Knowing when a model is the wrong tool
Recognising the problems a rule, a query or a lookup table solves better, cheaper and more predictably.
IR35 compliance
Miyagami employs every engineer directly, so IR35 status determinations don't fall on you. Contracts are with your UK entity, in GBP if you prefer.
Hiring locally in United Kingdom
- 4 months on average to hire
- Recruitment, payroll and compliance on you
Hiring with Miyagami
- Three weeks to first commit, contracts and payroll handled
- Wrong fit: we replace at our cost
AI-native engineer vs AI engineer
AI-native engineer and AI engineer are not the same role. This entry explains the difference, the overlap, and when you need which.
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 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.
Questions about hiring AI engineers
How much does it cost to hire a senior AI engineer in United Kingdom?
A senior local hire in the United Kingdom costs about £7,700 a month all-in, based on a senior software engineer median salary, statutory employer contributions and an amortised recruitment fee. Through us you pay a fixed monthly fee with employment and compliance included, and the pricing calculator shows the two side by side.
How long does it take to hire an AI engineer?
You get a shortlist in five working days and a first commit three weeks later. A local senior hire in the United Kingdom typically takes 4 months.
What do you test an AI engineer on?
Every AI engineer does both assessments, and two criteria apply only to this role: evaluation design, and knowing when a model is the wrong tool for the problem.
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.
