The main role of a Frontend Specialist is to independently deliver medium-complexity frontend features across web and mobile applications using React.js and React Native. The Frontend Specialist is responsible for translating product requirements into scalable technical solutions, building reusable UI components, integrating APIs and backend services, optimizing application performance, and contributing to frontend architecture and code quality standards. The role also includes mentoring junior developers, participating in code reviews, collaborating with cross-functional teams, and ensuring seamless user experiences across platforms.
Key Responsibilities:- Independently design and deliver medium-complexity features across React.js and React Native applications, with limited senior oversight.
- Translate product requirements into technical designs, breaking work down into estimable tasks and flagging risks early.
- Build, optimize, and maintain reusable UI components and contribute to the team’s shared component library.
- Implement and review integrations with RESTful APIs, payment endpoints, and back-end microservices, with attention to error handling and security.
- Apply performance optimization techniques in day-to-day work: lazy loading, memoization, bundle awareness, and React Native rendering performance.
- Conduct meaningful code reviews for junior developers and provide technical guidance during pair-programming and onboarding.
- Write and maintain unit and integration tests; contribute to the team’s end-to-end testing strategy under senior guidance.
- Participate in sprint planning, refinement, and estimation; own delivery of committed sprint work.
- Investigate, reproduce, and fix production defects, including participation in incident triage when frontend issues are involved.
- Contribute to internal documentation, coding standards, and knowledge-sharing sessions.
- Collaborate closely with UI/UX designers, backend engineers, and QA to deliver coherent end-user experiences.
Requirements
- 2–4 years of professional frontend development experience with hands-on production work in React.js and/or React Native.
- Bachelor’s degree in Computer Science, Software Engineering, IT, or a related technical discipline.
- Demonstrable track record of delivering features end-to-end with limited supervision.
- Portfolio, GitHub profile, or case studies showing real production work.
- Excellent communication and teamwork capabilities.
- Strong proficiency in JavaScript (ES6+) and working proficiency in TypeScript.
- Solid command of React.js: hooks, context, component composition, and common performance pitfalls.
- Practical experience building and shipping React Native features to iOS and Android, including debugging native build issues at a basic level.
- Hands-on experience with at least one state management library (Redux, MobX, or Zustand).
- Comfortable consuming and debugging RESTful APIs; basic exposure to WebSocket-based integrations.
- Confident with Git workflows: branching, rebasing, resolving conflicts, and structured pull requests.
- Experience writing unit tests with Jest and React Testing Library; familiarity with at least one E2E tool (Cypress, Playwright, or Detox).
- Working understanding of CI/CD pipelines (GitHub Actions, GitLab CI, or Jenkins).
- Awareness of common web security risks (XSS, CSRF, JWT/OAuth 2.0).
- Familiarity with responsive design, accessibility basics, and cross-browser/cross-device compatibility.
- Working knowledge of Angular (components, services, routing, reactive forms, RxJS, NgRx).
- Prior experience in fintech, banking, payments, or any regulated industry.
- Exposure to micro-frontend concepts or modular frontend architectures.
- Familiarity with performance monitoring tools (Lighthouse, Sentry, Datadog) and Core Web Vitals.
- Experience with UI component libraries (Ant Design, Material UI, PrimeNG) and/or Storybook.
- Basic understanding of native iOS (Swift) or Android (Kotlin).
- Exposure to server-side rendering frameworks (Next.js, Nuxt.js, or Angular Universal).
- Awareness of PCI-DSS or similar compliance considerations for frontend applications.
- Excellent communication and collaboration skills.
- Ability to work under pressure and manage multiple priorities effectively.
- Willingness to mentor junior developers and contribute to knowledge-sharing initiatives.
