Frontend Developer

Senior Front End Developer (Contract Position)

Team: Global Fulfillment and Technology — Digital Experience

Experience

Required:

5–8 years (Front End / React)

Education: Bachelor’s / Master’s in Computer Science, Software Engineering, or equivalent experience

We are seeking a skilled and motivated Senior Front End Developer to join a Global Fulfillment and Technology team. You will work within a cross-functional digital product squad — collaborating with product managers, UX/UI designers, back-end engineers, and platform architects — to build and evolve high-quality, performant, and accessible consumer-facing web experiences.

• Design, develop, and maintain scalable, reusable React component libraries and front-end applications aligned with enterprise design systems and brand standards.
• Integrate front-end applications with RESTful and Graph
  
  QL APIs, collaborating closely with back-end and platform engineering teams to define and validate API contracts.
• Implement and manage application state using Redux Toolkit, Zustand, or React Query, selecting the right pattern based on complexity and performance requirements.
• Own front-end build tooling and bundler configuration (Webpack, Vite, or Turbopack), optimizing for Core Web Vitals, bundle size, and time-to-interactive metrics.
• Contribute to and enforce front-end coding standards, patterns, and practices through pull request reviews and internal documentation.
• Partner with UX/UI designers (Figma) to translate design specifications into pixel-accurate, interaction-rich implementations with smooth animation and micro-interaction fidelity.
• Write and maintain unit, integration, and end-to-end tests using Jest, React Testing Library, and Playwright/Cypress to sustain a robust regression safety net.
• Work within Git Lab CI/CD pipelines to automate build, lint, test, and deployment stages; maintain and improve pipeline configurations as the team’s front-end coverage evolves.
• Monitor and triage front-end performance and error signals using observability tooling (Datadog RUM, Sentry, or equivalent); participate in incident response and post-incident reviews.
• Collaborate in Agile ceremonies — sprint planning, stand-ups, retrospectives, and backlog refinement — contributing front-end estimates and technical perspective to team planning.
• Drive continuous improvement in front-end architecture, identifying opportunities to reduce technical debt, improve developer experience, and adopt emerging web platform capabilities.

• 5–8 years of professional front-end development experience, with at least 3 years building production applications in React.js and Type Script.
• Deep expertise in the React ecosystem: hooks, context, concurrent rendering, code-splitting, Suspense, and server-side/static generation patterns with Next.js.
• Hands-on experience with state management libraries (Redux Toolkit, Zustand, Jotai) and data-fetching patterns (React Query / SWR / Apollo Client for Graph
  
  QL).
• Solid understanding of web performance fundamentals:
  Core Web Vitals (LCP, FID/INP, CLS), lazy loading, image optimization, CDN strategies, and caching.
• Proven experience writing front-end tests with Jest, React Testing Library, and at least one E2E framework (Playwright or Cypress).
• Practical knowledge of CI/CD workflows (Git Lab CI preferred) and developer tooling — ESLint, Prettier, Husky, Storybook, and Chromatic for component-level visual regression.
• Experience consuming and shaping REST and Graph
  
  QL APIs; familiarity with OpenAPI/Swagger specifications and mock-server tooling.
• Familiarity with cloud-hosted front-end delivery: AWS Cloud Front, S3 static hosting, or equivalent CDN/edge deployment patterns.
• Strong grasp of web accessibility standards (WCAG 2.1 AA) and experience using screen reader testing and automated accessibility tooling (axe, Lighthouse).
• Excellent communication skills — able to articulate technical trade-offs clearly to non-engineering stakeholders and contribute to design and architecture discussions.
• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or equivalent practical experience.

• Experience with micro-frontend architecture (Module Federation, single-spa) in a large-scale e-commerce or retail digital environment.
• Familiarity with A/B testing and feature flag tooling (Launch Darkly, Optimizely, or Statsig) integrated into front-end delivery pipelines.
• Understanding of Design Tokens, headless CMS integration (Contentful, Sanity), or composable commerce architectures.
• Prior experience working in a direct-to-consumer (DTC) retail or e-commerce environment.
