Hire React developers
These senior React developers build production interfaces with AI tools and review what those tools produce. Each one is tested on component architecture, state management, accessibility and reading design systems they didn't write.
01
Generated components still need checking
AI tools generate component scaffolding in seconds, so engineers spend less time writing boilerplate. What they spend more time on is verifying that generated output handles edge cases, meets accessibility standards, and fits the design system correctly.
02
State is where generated UI breaks
AI-generated components tend to handle happy-path rendering well and state logic poorly. Engineers who understand derived state, synchronisation and side-effect boundaries catch those breaks before they reach production.
03
Reading a design system you didn't write
Most React work today means joining an existing design system, so engineers need to read tokens, constraints and component APIs quickly. The ones who can do that without reworking what's already there ship sooner.
How we assess React developers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For React developers, these criteria carry the most weight.
- AI output verification
In React, this means catching generated hooks that introduce stale closures, incorrect dependency arrays, or accessibility violations that a tool won't flag on its own.
- Debugging
Engineers trace component re-renders, state synchronisation failures, and hydration mismatches in a real codebase under time pressure, without hints.
- Spec-driven development
Engineers build against a design-system spec and accessibility requirements, so we can see whether they read constraints first or generate first and patch later.

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 React developers
How senior are these React developers?
They're senior, with 6+ years' experience on average, and they've shipped and maintained production systems in React. Every one has passed both assessments, and you see their scorecards before you meet them.
How do you test React specifically?
Every React developer completes two assessments in a real codebase. The first assessment covers component architecture, state management and debugging without AI tools. The second assessment uses their own AI agents on a React task, so we can see how they verify and correct generated output.
How quickly can a React developer start?
You'll have a shortlist within five working days. From shortlist to first commit is typically three weeks. Engineers are available full-time and the minimum engagement is three months.
What does a React 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 React developers work in our tools or their own?
Engineers bring their own AI tools, agents and workflows, and you provide codebase access and context. The vetting confirms they can adapt to a design system and toolchain they haven't seen before.
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.
