#110 - Frontend Software Engineer - Payments Platform

Experience level: not applicable.

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.

Required Tools & Platforms

• TypeScript, React, and React Router.
• Webpack, with Module Federation or a similar remote-module architecture.
• SCSS/CSS Modules and Styled Components.
• GraphQL, Apollo Client, and GraphQL Code Generator or similar tooling.
• Jest, React Testing Library, and TestCafe, Cypress, or Playwright.
• GitLab CI or equivalent, Git, ESLint, and Prettier.
• Shared design systems, localization workflows, and automated accessibility testing tools.
