• 4+ years of hands-on experience, with demonstrated ownership of production services in a distributed systems environment.
• TypeScript and React, including functional components, hooks, context, and custom hooks.
• Proficiency with Webpack (bundling, code splitting) and component styling using SCSS/CSS Modules and Styled Components.
• Building and maintaining micro-frontend applications using Webpack Module Federation or similar platform-integrated remote module architectures.
• Strong working knowledge of GraphQL — writing queries and mutations, consuming them via Apollo Client (caching, reactive variables), and generating type-safe hooks with GraphQL Code Generator or similar tooling.
• Solid experience with React Router for client-side navigation and for building and validating complex forms.
• Strong production engineering mindset, including frontend telemetry, error logging, feature flags, gradual rollouts, and debugging user-facing production issues.
• Building accessible (a11y-compliant) and internationalized user interfaces using shared design systems, reusable component libraries, and localization workflows.
• Proficiency testing at all levels — unit and integration testing with Jest and React Testing Library, end-to-end testing with TestCafe, Cypress, or Playwright, and familiarity with automated accessibility testing tools.
• Comfort working in CI/CD pipelines (GitLab CI or equivalent) with strong command of ESLint, Prettier, and collaborative Git workflows, including branching, code reviews, and merge requests.
• Comfortable using modern coding assistants responsibly to accelerate code comprehension, implementation, refactoring, and test creation while maintaining ownership of quality, security, and correctness.
• Deep backend and distributed-systems experience, including exposure to async messaging and multi-datastore consistency challenges.
• Upper-intermediate English level.
NICE TO HAVES
• Prior experience in the Billing or Payments domain.
• Experience with high-scale, mission-critical frontend systems where UX quality, state-management correctness, accessibility, and performance are paramount.

• Strong collaboration with backend partners on API contracts.
WHAT YOU WILL DO
• Develop and maintain React micro-frontend solutions and web applications that power the Payments platform.
• Add new payment methods to the existing Payments platform capabilities.
• Contribute to feature development, bug fixes, and reliability improvements across these services.
