Mid/Senior Full-Stack Engineer (Web-first)

• 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.

• 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

SMG Swiss Marketplace Group runs some of Switzerland’s most-loved digital marketplaces. Our Sophia-Antipolis team builds Ricardo’s digital products - a TypeScript web monorepo (multiple SPAs) backed by Go microservices in separate repositories.
