Descripción del empleo

We are seeking an experienced Frontend Developer with strong React, React Router, and TypeScript skills to build and continuously improve a headless ecommerce storefront running on Cloudflare Workers and backed by our own commerce platform. This is primarily a frontend position (roughly 80% frontend, 20% backend). Most of your time will go into the React storefront: product and collection pages, search, cart, checkout, and customer accounts. The storefront talks to our Python/Django backend over a typed JSON API, and you'll make small, well-scoped backend changes when a frontend feature needs them, such as adding a field to an API response or a new endpoint, with support from the backend team.

You'll work in an established, well-tested codebase and collaborate with technical and nontechnical stakeholders to build polished ecommerce experiences, troubleshoot issues, evaluate feature feasibility, and recommend practical solutions.

Responsibilities

• Build and improve a server-rendered React storefront using React Router (framework mode) and TypeScript
• Build responsive, accessible interfaces with HTML, CSS, and Tailwind CSS
• Consume our REST/JSON API (types generated from its OpenAPI schema) for products, variants, collections, search, cart, checkout, orders, and accounts
• Build and maintain the checkout experience with Stripe Elements
• Build pages and content components with the Storyblok headless CMS
• Translate business requirements and rough mockups into intuitive, functional ecommerce experiences
• Evaluate proposed features for technical feasibility and recommend alternatives when API or platform limitations exist
• Troubleshoot issues across the storefront, the API, browser behavior, and third-party integrations
• Make light backend changes in Python/Django (API fields, small endpoints, tests) when a frontend feature needs them
• Implement and troubleshoot analytics and marketing integrations (GA4, Klaviyo)
• Support ecommerce SEO requirements including redirects, canonical tags, structured data, breadcrumbs, metadata, and indexability
• Improve frontend performance (Core Web Vitals), usability, and maintainability
• Write unit tests (Vitest, Testing Library) and end-to-end tests (Playwright) as part of a test-first workflow
• Communicate technical constraints, tradeoffs, and recommendations clearly to technical and nontechnical team members

Requirements

• 3+ years of professional experience with React, TypeScript, JavaScript, HTML, and CSS
• Hands-on experience with React Router 7 / Remix or a similar server-rendering React framework (e.g. Next.js)
• Experience building or maintaining ecommerce storefronts (product pages, faceted search, cart, checkout)
• Experience consuming REST/JSON APIs and integrating third-party services
• Working knowledge of a backend language and framework, preferably Python/Django, enough to read the code and make small changes
• Experience writing automated tests for frontend code
• Strong debugging and troubleshooting skills, including browser dev tools and network inspection
• Proficiency with Git and pull-request-based workflows
• Ability to work within and improve an existing codebase

Frontend / Product

• Strong UI/UX judgment
• Ability to translate business requirements or rough mockups into functional interfaces
• Understanding of responsive and accessible frontend development
• Ability to identify technical or usability limitations before implementation
• Ability to recommend practical alternatives when a requested approach is not technically appropriate

Communication

• Excellent English communication skills
• Able to clearly explain technical constraints and tradeoffs to both technical and nontechnical stakeholders
• Comfortable working independently and taking ownership of assigned work

Nice to Have

• Cloudflare Workers or another edge runtime
• Tailwind CSS
• Storyblok or another headless CMS
• Stripe (Payment Element, Payment Intents)
• Django, Django Ninja/FastAPI, or PostgreSQL
• Elasticsearch-backed search UX (facets, autocomplete, recommendations)
• Ecommerce analytics and event tracking, including GA4
• Klaviyo or similar marketing integrations in a headless environment
• Ecommerce SEO and replatforming/site migrations
• Playwright, OpenAPI-generated types, and CI/CD workflows
• AI coding assistants as part of daily development
