Participate in code reviews, providing and receiving constructive technical feedback
Technical Contribution:
Take meaningful ownership of micro-frontend architecture decisions — module federation, shared dependencies, and deployment boundaries.
Identify and resolve performance bottlenecks in rendering, state management, and data fetching
Apply security best practices (XSS, CSRF prevention, secure payment data handling) in all frontend work
Support CI/CD pipelines and assist in maintaining build tooling
Collaboration:
Work within an agile team, actively participating in sprint planning, standups, reviews, and retrospectives
Partner with backend and platform engineers to design clean API contracts
Unblock teammates through technical guidance and knowledge sharing
Communicate technical tradeoffs clearly to teammates and product stakeholders
Growth:
Mentor junior and mid-level developers through code reviews, pairing, and documentation
Stay current with React ecosystem trends and advocate for adoption where appropriate

Experience consuming RESTful APIs and integrating frontend applications with backend services
Familiarity with CI/CD pipelines and DevSecOps practices
Strong communication skills and a collaborative working style
Skills:
React.js: Strong command of hooks, context API, component lifecycle, and performance optimization patterns
Micro-Frontend Architecture: Proven experience owning and evolving module federation (Webpack 5) and MFE composition patterns
State Management: Experience with Redux, Zustand, or similar; sound judgment on global vs. local state, including complex multi-step transactional flows
Testing: Proficiency with Jest and React Testing Library; experience with Cypress or Playwright for E2E testing
Build Tools: Working knowledge of Webpack, Rollup, or Vite
