#110 - Frontend Software Engineer - Payments Platform

We are seeking a frontend engineer to build and maintain high-scale web applications for a payments platform.

You will extend payment capabilities, add payment methods, and improve the reliability of mission-critical web applications using React and TypeScript.

Enterprise experience strongly preferred.

Key Responsibilities - Develop and maintain React micro-frontend solutions and web applications for a payments platform. - Add new payment methods to existing platform capabilities. - Deliver features, bug fixes, and reliability improvements. - Deliver production-ready changes through automated CI/CD pipelines with strong test coverage. - Write comprehensive unit, integration, and end-to-end tests to support application reliability.

Must-Have Skills - BS or MS in Computer Science, or equivalent. - 5+ years of hands-on experience at a mid-to-senior level, with demonstrated ownership of production services in a distributed systems environment. - TypeScript and React, including functional components, hooks, context, and custom hooks. - Webpack bundling and code splitting, with component styling using SCSS/CSS Modules and Styled Components. - Experience building and maintaining micro-frontends using Webpack Module Federation or similar platform-integrated remote module architectures. - Strong working knowledge of GraphQL queries and mutations, Apollo Client caching and reactive variables, and type-safe hooks generated with GraphQL Code Generator or similar tooling. - Solid React Router experience for client-side navigation, plus experience building and validating complex forms. - Production engineering experience with frontend telemetry, error logging, feature flags, gradual rollouts, and debugging user-facing production issues. - Experience building accessible and internationalized interfaces using shared design systems, reusable component libraries, and localization workflows. - 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. - CI/CD experience with GitLab CI or equivalent, plus ESLint, Prettier, and collaborative Git workflows including branching, code reviews, and merge requests. - Responsible use of modern coding assistants for code comprehension, implementation, refactoring, and test creation while retaining ownership of quality, security, and correctness. - Strong working knowledge of backend and distributed systems, including asynchronous messaging and multi-datastore consistency.

End-to-end ownership of backend systems is not required, but limited understanding of these concepts is insufficient.

Nice-to-Have Skills - Prior billing or payments domain experience. - Experience with high-scale, mission-critical frontend systems where user experience, state-management correctness, accessibility, and performance are essential. - Clear reasoning about client-side architecture, including micro-frontends, module federation, and caching strategies. - Strong collaboration with backend partners on API contracts.
