Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Mid/Senior Full-Stack Engineer (Web-first) - **Company:** SMG Swiss Marketplace Group - **Location:** Valbonne, France (Remote available) - **Experience:** Experienced - **Contract:** Permanent contract - **Skills:** Java (Programming Language), Application Programming Interfaces (APIs), Artificial Intelligence, Software Quality, Code Review, Cursor (Graphical User Interface Elements), Python (Programming Language), Node.Js, Open Source Technology, TypeScript, Web Applications, Web Services, ReactJS, Backend, Kotlin, Front End Software Development, Marketplace, Microservices - **Published:** July 9, 2026 - **Apply:** https://fr.indeed.com/viewjob?jk=4b6bf3f8c60efdd9 ## About the Role * 3-5 years shipping production web apps in React and TypeScript * Real backend experience - you've owned APIs and services in production (not only "called REST from the front") * Comfortable in a large web codebase (monorepo, multi-app, or shared design system) * You integrate front and back - schemas, errors, auth, idempotency, and "what happens when this fails" * You can explain your design choices - in a PR, to a teammate, or in an interview * Good English - our team is international and English is our working language Nice-to-haves: * Go already (bonus, not required) - most backend here is Go; strong Node, Java, Python, or Kotlin backgrounds are a great fit to learn Go with us * Marketplace, e-commerce, or high-traffic consumer products * Feature flags, analytics events, and i18n (e.g. Phrase) * Open-source or side projects that show full-stack craft You'll thrive here if... * You're strong on the web and genuinely want to keep writing backend code, not delegate it away * You're fine with uneven weeks - deep in React one sprint, in Go services the next * You can build a feature without waiting for a spec on every line * You're comfortable saying "I think there's a better way" and backing it up * You care about code quality and shipping - not one at the expense of the other This role isn't for you if... * You want frontend-only or backend-only - we need both, with a web-first home base * You haven't shipped to production in the last 2 years * You need full remote - this role is 2 days per week on site in Sophia-Antipolis (Valbonne) * You treat AI-generated code as ready to merge without review ## Description * Build features end-to-end - React/TypeScript in our web monorepo and changes in existing Go microservices when the feature needs it. * Own vertical slices - UI, API contract, backend implementation, tests, and production follow-up. * Ship on the web monorepo - orders, checkout, listing, shared packages, design-system and platform work * Contribute to Go services - extend and maintain existing services (separate repos); no prior Go required - we'll help you ramp up * Review and be reviewed - we take code reviews seriously; expect to give and receive honest feedback * Collaborate cross-functionally - Product, Design, mobile, and Backend peers (our squad is Go-first; Java exists elsewhere in the group - you might cross paths occasionally, not every day). * Work AI-augmented - Cursor, Copilot, and similar tools are part of how we work; fast iteration and careful review. ## About SMG Swiss Marketplace Group **Welcome to SMG Swiss Marketplace Group AG** We are a pioneering network of online marketplaces and a cutting-edge European digital company that simplifies people’s lives with innovative products.
