Hire senior frontend engineers for French teams
Senior frontend engineers own interfaces, state, performance and accessibility. Each one is tested on fundamentals with AI tools off, then on checking AI-generated components that look correct but fail keyboard and screen-reader checks. A senior local hire in France takes 4 months on average.
01
Models produce UI that looks finished
A generated component can pass a visual check and still fail a keyboard or screen-reader test, and the model won't flag it. Your frontend engineer has to find that gap before your users do.
02
AI struggles with state and performance
Models are good at producing screens that look right, and they're much worse at state management, performance and accessibility. The engineer has to catch what the model misses.
03
Verification replaced building as the core skill
The role has shifted from turning designs into components to checking whether AI-generated components hold up on slow phones and with screen readers. Spotting confident mistakes is now a central part of the job.
How we assess frontend engineers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For frontend engineers, these criteria carry the most weight.
- AI output verification
Engineers review generated components that look correct visually but fail keyboard navigation or screen-reader tests, and must catch the failure without a prompt from us.
- Debugging
The first assessment puts engineers in a real codebase without AI tools, so we see whether they can trace accessibility or state bugs through to the root cause on their own.
- Technical understanding
We check that engineers understand why a generated component fails, covering accessibility semantics, state behaviour and performance characteristics.
Cost against a local hire
Engineers are Miyagami employees who work full-time in your team under a service agreement, so there's no individual contractor risk for you. Invoices are monthly, in EUR if you prefer.
Hiring locally in France
- 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
How to review AI-generated code
Reviewing AI-generated code changes some of what reviewers look for and keeps the rest. This entry covers both, plus the specific failure modes to check for.
How do you test software you didn't design
Standard coverage metrics mislead when you test software you didn't design. This entry explains what engineers should do instead when reviewing AI-generated code.
What is a coding agent
A coding agent is an AI system that writes, edits, runs and debugs code autonomously across multiple steps, without a human directing each action.
Questions about hiring frontend engineers
How much does it cost to hire a senior frontend engineer in France?
A senior local hire in France costs about €12,200 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 a frontend engineer?
You get a shortlist in five working days and a first commit three weeks later. A local senior hire in France typically takes 4 months.
What do you test a frontend engineer on?
Every frontend engineer completes both assessments, and in the second they have to catch a model that's confidently wrong about accessibility. The generated components look right and pass a visual check but fail a keyboard or screen-reader test.
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.
