Core Responsibilities (React / React‑Native Engineer)

• Component Development

  • Design, implement, and maintain reusable UI components using React.js and React Native.
  • Translate wireframes & mockups (Figma/Sketch) into pixel‑perfect, responsive interfaces.

• Performance & Optimization

  • Profile and fine‑tune components for speed and low memory footprint across browsers & devices.
  • Apply lazy‑loading, code‑splitting, memoization, and other performance patterns.

• Code Quality & Architecture

  • Write clean, modular, and scalable code following SOLID, DRY, and KISS principles.
  • Enforce consistent code style with ESLint/Prettier and conduct thorough code reviews.

• Testing & Reliability

  • Develop unit and integration tests with Jest, Mocha, and Enzyme; achieve ≥ 80 % coverage.
  • Implement Test‑Driven Development (TDD) where appropriate.

• Collaboration & Delivery

  • Partner with designers, product owners, and backend engineers to align UI with business goals.
  • Participate in Agile ceremonies (Sprint Planning, Daily Stand‑ups, Retrospectives).

• Documentation & Knowledge Sharing

  • Produce component documentation (props, usage examples, edge‑case handling).
  • Maintain technical specs in Confluence and keep the codebase well‑commented.

• Security & Best Practices

  • Integrate security measures (input sanitization, CSP, secure storage) to protect user data.
  • Stay current on OWASP top‑10 vulnerabilities and apply mitigations.

• DevOps & CI/CD

  • Configure build pipelines (Azure DevOps, GitHub Actions) for automated linting, testing, and deployment.
  • Containerize front‑end services with Docker; orchestrate with Kubernetes when needed.

• Continuous Learning

  • Keep abreast of emerging React ecosystem trends (React 18, Server‑Side Rendering, Concurrent Mode).
  • Experiment with new libraries (e.g., React Query, Recoil) and share findings with the team.

Nice‑to‑Have Extras

• Hands‑on experience with API Gateways (Kong, Azure API Management, AWS API Gateway, CA API GW).
• Familiarity with Agile methodologies (Scrum, Kanban) and Test‑Driven Development.
• Exposure to Gradle, Maven, and Azure DevOps build pipelines.
