Senior Front End Developer, React.js

About the Role Techylla is looking for a Senior Frontend Developer who doesn't just write components - who builds experiences people actually enjoy using. This is a role for someone who's already fluent in the modern React ecosystem and wants to bring that craft to fast-moving, client-facing products from day one.

You'll own the front-end architecture for enterprise-grade applications — working with the latest React patterns, performance techniques, and tooling, alongside a team that values clean code, thoughtful UX, and shipping fast without cutting corners. If you're the kind of developer who reaches for the newest stable tooling because it makes the product better (not just because it's new), this role is built for you.

We need someone who can start immediately and hit the ground running — no lengthy ramp-up, no hand-holding on fundamentals.

Why This Role Stands Out

Work with the newest stack: React 19, Next.js App Router, TypeScript, and modern state/data tooling — not a legacy codebase you'll spend a year modernising

Own the front end end-to-end: From architecture decisions to performance and accessibility — your calls shape the product

Direct client visibility: Work closely with US-based stakeholders and see your work ship to real users, fast

Immediate impact: Join a lean, high-trust team where a strong contributor is felt from week one, not lost in process

Must-Have Qualifications

Overall experience: 5–8 years of hands-on front-end development experience, with strong, demonstrable expertise in React

Bachelor's or Master's degree in Computer Science, Information Technology, Engineering, or a related discipline

Immediate availability: Available to join within 0–15 days — this is a mandatory requirement for this role

• Core React & Modern Front-End Engineering

React (latest): Strong hands-on experience with React 18/19, functional components, Hooks, Concurrent Rendering, and Suspense

Next.js: Practical experience with the App Router, Server Components, SSR/SSG/ISR, and route-level optimization

TypeScript: Strong typing discipline across components, hooks, and API contracts

State & data management: Redux or Redux Toolkit for client state, and TanStack Query (React Query) or SWR for server-state/data-fetching

Styling: Tailwind CSS, CSS-in-JS (styled-components/Emotion), or modern CSS Modules with responsive, design-system-driven UI

• Performance, Quality & Tooling

Build tooling: Vite or Turbopack, module federation/micro-frontend exposure a strong plus

Testing: Jest, React Testing Library, and Playwright or Cypress for end-to-end coverage

Performance engineering: Code-splitting, lazy loading, bundle analysis, Core Web Vitals optimization

Component systems: Experience building or consuming design systems with Storybook

Accessibility: Working knowledge of WCAG standards and semantic, accessible component design

• Integration & Collaboration

API integration: REST and GraphQL (Apollo Client or urql) consumption experience

Version control & CI/CD: Git-based workflows, PR review discipline, and familiarity with CI/CD pipelines (GitHub Actions, Azure DevOps, or similar)

Cross-functional collaboration: Comfortable working directly with designers, backend engineers, and US-based product stakeholders

Preferred Qualifications

Exposure to micro-frontend architectures (Module Federation, single-spa)

Experience with React Native for cross-platform mobile development

Familiarity with AI-assisted development tools (GitHub Copilot, Cursor) to accelerate delivery

Exposure to Web Components or design tokens for multi-framework design systems

Prior experience in a client-facing or consulting environment

Role & Responsibilities

Design, build, and maintain scalable, high-performance React applications used by real clients in production

Translate UX/UI designs into pixel-accurate, accessible, and responsive components

Own front-end architecture decisions — state management, folder structure, rendering strategy, and performance budget

Write clean, well-tested, well-documented code and actively participate in code reviews

Optimize applications for speed, accessibility, and cross-browser/cross-device compatibility

Collaborate directly with backend engineers to define and consume APIs (REST/GraphQL)

Contribute to and evolve a shared component/design system

Stay current with the React ecosystem and proactively recommend tooling or pattern upgrades

Communicate progress, blockers, and technical trade-offs clearly to both technical and non-technical stakeholders

Behavioral Attributes

Self-starter who can move fast with requirements

Strong ownership mentality — treats the product like it's their own

Detail-oriented with a genuine eye for UI polish and user experience

Comfortable working directly with clients and handling ambiguity

Curious and current — actively follows the React/front-end ecosystem rather than working off outdated patterns
