Customer-aligned requirement | React, TypeScript and Micro-Frontend Engineering

Target profile: Senior / Lead-capable engineer with strong React and TypeScript fundamentals, practical micro-frontend understanding, unit-testing capability, and end-to-end production ownership.

Role Summary

The Senior Front-End Developer will build scalable, production-ready web applications and take ownership of features from solution design through release and operational support. The role requires strong hands-on React and TypeScript skills, sound front-end architecture knowledge, and the ability to communicate technical decisions clearly and work independently across engineering disciplines.

Mandatory Technical Skills

• Strong hands-on proficiency in React, React Hooks, reusable component design, and component-driven architecture.
• Strong TypeScript and modern JavaScript (ES6+) capability, with solid HTML5 and CSS3 fundamentals.
• Practical understanding of micro-frontend architecture, preferably including Webpack Module Federation. Candidates with exceptional React and TypeScript strength may be considered where they can demonstrate readiness to learn and apply the pattern quickly.
• Solid knowledge of front-end architecture and React patterns, including modular design, code splitting, lazy loading, performance optimization, scalability, and maintainability.
• Experience with scalable state-management approaches, including Redux, Redux Toolkit, Context API, or equivalent patterns.
• Ability to build responsive, mobile-first, accessible, and cross-browser-compatible user interfaces.
• Ability to write meaningful unit tests. Experience with Jest and React Testing Library, or comparable frameworks, is expected.
• Strong debugging and problem-solving skills using browser developer tools, performance profilers, tracing, and systematic root-cause analysis.

Engineering Ownership and Production Readiness

• Own initiatives end to end, from requirements and solution-architect discussions through implementation, testing, production release, and post-release support.
• Write clean, maintainable, secure, and production-oriented code while following agreed architectural patterns and engineering standards.
• Understand and use feature flags, environment variables, application configuration, utilization monitoring, data tracing, observability, and user analytics.
• Understand how applications move across development, test, release, and production environments. Direct ownership of deployment tooling is not mandatory.
• Apply performance optimization techniques and assess application behavior using Chrome DevTools, React profiling, browser performance tooling, or equivalent tools.
• Demonstrate independent delivery, sound technical judgement, and the ability to explain implementation choices and trade-offs.

Micro-Frontend and Practical Exercise Expectations

• Be able to build a simple static micro-frontend application and explain the architecture without depending on existing business logic or APIs.
• Be able to fetch and render data in a React application and structure the solution using appropriate components, state, error handling, and tests.
• Demonstrate the ability to validate, troubleshoot, and simplify an implementation rather than relying uncritically on generated guidance.
• Explain how independently deployable front-end modules can be integrated, versioned, tested, and operated within a broader application.

Testing Expectations

• Unit testing is mandatory for this senior-level role.
• Integration-testing experience is desirable.
• Cypress, BDD, and broader automation-testing expertise are useful but are not mandatory selection criteria.

Collaboration and Code Quality

• Work effectively with solution architects, designers, backend engineers, QA, product teams, and other stakeholders.
• Use Git workflows confidently, including branching, merging, pull requests, code review, and conflict resolution.
• Clearly articulate technical reasoning, design decisions, risks, assumptions, and trade-offs.
• Contribute to front-end standards, reusable patterns, engineering best practices, and continuous improvement.
• Mentor or support other engineers where required and contribute at a senior or lead-capable level.

Preferred / Nice-to-Have Skills

• Experience with Sass, Less, or another CSS pre-processor.
• Experience with CMS platforms.
• Exposure to analytics libraries or platforms such as Adobe or Google solutions.
• Experience with CI/CD concepts, application monitoring, telemetry, and production support.
• Good visual judgement and understanding of UI and UX design principles.

Candidate Screening Guidance

• Prioritize candidates who strongly demonstrate React and TypeScript capability and can independently complete practical coding exercises.
• Validate micro-frontend understanding through practical implementation or a clear explanation of the pattern and its trade-offs.
• Confirm unit-testing experience and request examples of tests written for components, hooks, state, and asynchronous behavior.
• Assess whether the candidate has taken features from early design discussions through production and can describe operational considerations.
• Target candidates who meet approximately 8090% of the overall expectations, without compromising the mandatory engineering fundamentals.
