How to get a
React developer job in 2027

React developers build interfaces from components — reusable pieces that take props, manage state and render UI. Day to day that means designing component structure, managing state and data, handling forms and interactions, keeping things fast and accessible, and testing behaviour. Most React work now happens inside frameworks like Next.js, with TypeScript, and with React 19 features such as actions and form hooks, and Server Components where the framework supports them.⁵

React is the most requested front-end skill in job listings across India's product companies and global capability centres. AmbitionBox shows typical React developer pay of ₹5.7–6.3 lakh in October 2026, rising to ₹7–7.7 lakh at 3–6 years;¹ the broader front-end developer title typically earned ₹6.1–6.7 lakh.²

Table: How React hiring has changed (editorial summary)

• Two deployed apps — with real APIs, not static data.
• All states handled — loading, error, empty and success.
• TypeScript — typed props and API responses.
• Sensible structure — small components, custom hooks for shared logic.
• Tests — key user flows with React Testing Library.
• Accessibility — keyboard support and labelled controls.

Recruiters filter on: React Developer, React.js Developer, Front-End Engineer, UI Engineer; React, Next.js, TypeScript, JavaScript, Redux Toolkit, TanStack Query, React Hook Form, Tailwind, Jest, React Testing Library, Storybook, accessibility, Web Vitals.

Write bullets with outcomes: "Replaced effect-driven data fetching with TanStack Query; removed 30% of re-renders on the product page and fixed stale-results bugs."

function ProductSearch() {
  const [query, setQuery] = useState("");
  const debounced = useDebounce(query, 250);
  const { data, isLoading, error } = useQuery({
    queryKey: ["products", debounced],
    queryFn: ({ signal }) => fetch(`/api/products?q=${encodeURIComponent(debounced)}`, { signal }).then((r) => r.json()),
    enabled: debounced.length > 1,
  });

  return (
    <div role="combobox" aria-expanded={!!data?.length} aria-haspopup="listbox">
      <label htmlFor="q">Search products</label>
      <input id="q" value={query} onChange={(e) => setQuery(e.target.value)} />
      {isLoading && <p>Searching…</p>}
      {error && <p role="alert">Couldn't load results.</p>}
      {data?.length === 0 && <p>No matches.</p>}
      <ul role="listbox">{data?.map((p) => <li role="option" key={p.id}>{p.name}</li>)}</ul>
    </div>
  );
}

What to say while writing it: the debounce limits requests, the query key and abort signal prevent stale responses from overwriting newer ones, every state is handled, keys use stable IDs, and the roles and label make it usable with a keyboard and screen reader. In a full answer, add arrow-key navigation.

"When does a component re-render?"

When its state changes, its parent re-renders or a context it reads changes. Props changing is a consequence of the parent rendering.

"Why do lists need keys?"

Keys let React match items between renders; using array indexes breaks when items are reordered or removed, causing wrong state to attach to wrong items.

"useMemo or useCallback — when?"

Only when a calculation is expensive or a stable reference prevents measurable re-renders of memoised children. Measure first.

"Controlled vs uncontrolled inputs?"

Controlled inputs keep their value in React state; uncontrolled ones keep it in the DOM, read with refs or form actions. React 19's form actions make uncontrolled forms more common again.

"What are Server Components?"

Components that render on the server, can access data directly and send no JavaScript for themselves to the browser. Interactive parts are Client Components.

"How do you share logic between components?"

Custom hooks for stateful logic, components for shared UI, context for values many components need.

"How would you find a performance problem?"

React DevTools Profiler to see what renders and why, then fix state placement or expensive work before adding memoisation.

"How do you test a component?"

Render it, interact as a user would (Testing Library queries by role and label) and assert on what the user sees — not on internal state.

• Component — a function that returns UI from props and state.
• Hook — a function like useState or useEffect that lets components use React features.
• Re-render — React calling a component again to compute updated UI.
• Server Component — a component rendered on the server that ships no client JavaScript itself.
• Controlled input — a form field whose value is held in React state.
