We are currently looking for a Frontend Developer to join a fast-growing U.S.-based e-commerce marketplace.

The team is responsible for building the platform that powers how sellers list, price, and fulfill products. They focus on the seller experience, developing tools for listing management, bulk price updates, and pricing rules.

Their frontend supports thousands of sellers across categories such as sneakers, apparel, and collectibles, managing real-time pricing updates, complex data tables, and interactive workflows at scale.

In this role, you will:

- Own the frontend for seller listing management and repricing tools end-to-end: from technical design to deployment, monitoring, and iteration

- Build and maintain React applications that power complex seller workflows — bulk editing, pricing rules, inventory views, and real-time data displays

- Use AI-assisted development workflows daily (Claude Code, Cursor, Copilot) to ship features faster, write tests, debug issues, and prototype UI

- Write well-tested code as a matter of course — unit tests, integration tests, and end-to-end coverage are part of how you ship, not an afterthought

- Work closely with product and design to translate requirements into polished, performant interfaces

- Understand the Express/Node.js server layer and API contracts that connect the frontend to backend microservices, and debug across that boundary when needed

- Contribute to technical design decisions, code reviews, and architecture documentation that shapes how the seller platform evolves

We are looking for:

- 3+ years of frontend software engineering experience, with strong proficiency in React and TypeScript

- Deep experience with React ecosystem tools: Redux, React Router, styled-components, and state management patterns. Comfort working in large, mature React codebases.

- Experience with modern frontend frameworks and patterns: Next.js, TanStack Query, Tailwind CSS, React Hook Form, Zod

- Working knowledge of Node.js/Express server-side rendering and API layers — you can read and reason about server-side code, understand API contracts, and debug issues that span the client-server boundary

- Strong understanding of component architecture and design system principles — you build reusable, well-structured components without needing to be told

- Proven, daily use of AI-assisted development tools (Claude Code, Cursor, Copilot, or similar). You use AI to accelerate feature development, generate tests, debug complex issues, and iterate on UI.

- Experience with frontend testing frameworks (Jest, React Testing Library, Playwright, or similar)

- Comfort with build tooling and bundlers (Webpack, Next.js build pipeline)

- Bias towards action: you pick up ambiguous problems and drive them forward without waiting for direction

- Curiosity: learning new tech is invigorating. You stay up to date with the latest because it's fascinating.

Nice to have:

- E-commerce or marketplace platform experience

- Experience with search UI (Algolia, InstantSearch)

- Frontend observability and performance monitoring (Bugsnag, FullStory, Core Web Vitals)

- Experience with internationalization (i18next or similar)

- Familiarity with gRPC / Protocol Buffers consumed from a frontend context

- Experience with Storybook or similar component development environments

The role involves working closely with U.S.-based teams, requiring strong English communication skills and a high level of autonomy and proactivity to collaborate effectively in a global environment.
