How to hire a React developer — a guide for non-technical recruiters
- React developers build user interfaces for web applications — the part users see and interact with
- The skills that matter change significantly between junior, mid, and senior levels
- You can evaluate React skills without coding knowledge using structured assessments
- Red flags include no testing experience, no TypeScript, and only tutorial-level projects
1. What does a React developer actually do?
A React developer builds the user-facing part of web applications using React, a JavaScript library created by Meta. They turn designs into interactive interfaces, manage application state, and ensure the UI performs well across devices.
React is the most widely used frontend framework. When a company says they need a "React developer," they need someone who can build, maintain, and improve the user interface of their web application.
2. The skills that matter — junior vs mid vs senior
Junior (0–2 years): Can build components, use hooks (useState, useEffect), and work within an existing codebase. Needs guidance on architecture decisions.
Mid (2–5 years): Understands component architecture, state management patterns, TypeScript integration, testing, and performance optimization. Can work independently.
Senior (5+ years): Makes architectural decisions, mentors junior developers, thinks about scalability and maintainability, and can evaluate tradeoffs between approaches.
3. What good looks like on a React developer résumé
Specific React projects with described scope. TypeScript alongside React. Testing frameworks mentioned (Jest, React Testing Library). State management experience. Production deployments, not just side projects.
4. Red flags to watch for
- • Lists React but all projects use jQuery or vanilla JavaScript
- • No testing experience mentioned anywhere
- • Only tutorial-level or bootcamp projects — no production experience
- • Lists every frontend framework (React, Vue, Angular, Svelte) without depth in any
- • Can't articulate component architecture decisions in conversation
5. Questions to ask in the recruiter screen
- • "Walk me through a React project you built. What was your role?"
- • "What state management approach did you use and why?"
- • "How do you decide when to break a component into smaller pieces?"
- • "What's your approach to testing React components?"
- • "Tell me about a performance issue you diagnosed and fixed."
6. How to evaluate React skills without coding knowledge
You don't need to read code. You need structured data. A well-designed assessment evaluates hooks, architecture, state management, TypeScript, testing, and performance — then delivers results you can read, share, and act on.
7. Using Beaverhand to assess React candidates
Beaverhand's React Developer assessment evaluates 7 skill areas in 45–60 minutes. The candidate completes it async. You receive a plain-language report with skill ratings, red flags, seniority signal, and 3 suggested interview questions — in under 5 minutes. No engineer required.
