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

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. We're a small team that ships fast, debates trade-offs openly , and cares about doing things right — not just getting things done . Work ebbs and flows: sometimes we're web-heavy, sometimes the squad needs more backend — you'll be part of both. What you'll do ️️️🛠️ ● 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. What you bring 💻 Must-haves: ● 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 What we offer 🤝 ● Hybrid work : 2 days in office per week, up to 3 days from home — you choose which office days ● 37 days off : 25 holidays + 12 recovery days ● Learning budget : Conferences, courses, books — invest in yourself (including Go if that's new to you) ● Great gear : MacBook Pro, ergonomic setup, and all the coffee and tea you need ☕ ● Swiss trips : Regular visits to our Zurich HQ ● Team culture : Apéros, team events, and people who actually like working together Hiring process 📆 We believe hiring is a two-way street. Here's what to expect: 1. Intro call with Sébastien (45 min) — role, how we balance web vs backend, your questions 2. Design session (45 min) — how you'd approach a real product slice across web monorepo and Go services 3. Coding session (60 min) — practical work in React/TypeScript plus discussion of backend design (Go welcome, not mandatory in the room) 4. Team fit & HR (90 min) — meet the squad, discuss logistics Location: You need to be commutable to Valbonne (Sophia-Antipolis) with a valid workpermit. Full remote is not available. Ready? 🚀 Send your CV in English and let's talk. Include GitHub or examples of work that shows web + backend — even if backend was Node, Java, Python, or Kotlin; we'll teach you the Go we use day to day.
