About the Role
Groupon connects 42 million customers with local experiences - restaurants, events, wellness and travel - and the million-plus merchants who deliver them.

We're an AI-native company in the middle of a platform transformation, moving from a deals marketplace to an experience discovery platform that works for customers and merchants at the same time.

Full-Stack Builder — B2C Mobile Experience
Groupon's B2C mobile experience spans the full customer journey — homepage, browse, deal pages, voucher creation, receipts, post-purchase. This role owns front-end delivery for MobileNext, the pre- and post-purchase experience used by millions of customers daily. When this hire is operating well, customer journeys ship faster and the team spends less time on rework.
Who you'll work with
Report to Tomáš Rous, Engineering Director - B2C. A 4-person team working across product, design, and engineering on the consumer-facing product. One honest signal: this team expects you to take features from problem definition to production without handholding — if you need a fully scoped ticket before moving, this environment will frustrate you.
What you'll be doing
- Owning customer-facing features end-to-end across homepage, browse, deal pages, and post-purchase flows — from problem definition through production deployment, your name is on it
- Using AI tools (Claude Code, Cursor, Copilot) as your primary development accelerant, shipping faster without trading away engineering quality
- Maintaining code quality in a fast-moving codebase, catching the regressions before they reach customers
- Supporting end-to-end testing so what ships works and what breaks gets caught before production
- Navigating ambiguity and delivering under pressure — priorities shift, and you adjust without waiting to be told
What success looks like
Day 30: Environment set up, first PR merged, first feature shipped or in active review. You can describe the key customer journeys and the technical dependencies between them.
Day 60: Independently owning a feature from kick-off to production. Your AI tooling setup is established and visibly accelerating your output.
Day 90: Shipping consistently without supervision. You've identified at least one area of the codebase that needs improvement and proposed a concrete plan.
What this role demands
- Production TypeScript, React, Next.js, and Node.js — shown through shipped consumer-facing software
- AI-first working practice: Claude Code, Cursor, or Copilot is already how you work, not something you'd consider adopting
- Independent problem-solving — you unblock yourself, not your manager
- Sound debugging skills across the stack — you find root causes, not nearest workarounds
- Ability to work from Madrid or Prague with regular in-office attendance
How we operate
Extreme Ownership: Your name is on the features you ship. End-to-end means end-to-end — including what breaks after deploy.
Speed Over Comfort: Working features in front of customers beat polished designs still in review. Ship and iterate.
Impact Obsessed: Conversion rates and customer journeys that break less are the measure of success, not story points closed.
