Groupon is a marketplace where customers discover new experiences and services everyday and local businesses thrive. To date we have worked with over a million merchant partners worldwide, connecting over 16 million customers with deals across various categories. In a world often dominated by e-commerce giants, we stand out as one of the few platforms uniquely committed to helping local businesses succeed on a performance basis.
Groupon is on a radical journey to transform our business with relentless pursuit of results. Even with thousands of employees spread across multiple continents, we still maintain a culture that inspires innovation, rewards risk-taking and celebrates success. The impact here can be immediate due to our scale and the speed of our transformation. We're a "best of both worlds" kind of company. We're big enough to have the resources and scale, but small enough that a single person has a surprising amount of autonomy and can make a meaningful impact.
About the Role
We are hiring a full-stack builder (AI-First) with a strong focus on front-end delivery for our B2C MobileNext pre-purchase and post-purchase experience. The team owns key customer journeys across homepage, browse pages, deal pages, voucher creation, receipts, and post-purchase pages. This is a hands-on role for someone who can move fast, solve problems independently, and use AI tools as part of everyday engineering work.
Key Responsibilities
- Use AI tools to accelerate coding, debugging, and problem solving without losing engineering quality.
- Build and improve customer-facing experiences
- Own features end to end, from understanding the problem to shipping and debugging in production.
- Work closely with product, design, and engineering partners to improve pre-purchase and post-purchase flows.
- Contribute to code quality, maintainability, and practical technical decisions.
- Support testing and validation, including end-to-end testing where relevant.
- Help the team move through ambiguity and delivery pressure with a calm, structured approach.
Key Requirements
- Hands-on experience with TypeScript, React, Next.js, Node.js, and GraphQL.
- Solid front-end engineering skills and comfort working in a modern JavaScript ecosystem.
- Proven ability to solve problems independently with minimal hand-holding.
- Practical AI-first mindset: uses AI tools to work faster and smarter.
- Good debugging skills and sound technical judgment.
- Clear communication and ownership in a fast-changing environment.
- Ability to work from one of the supported hubs, with regular office attendance as required.
Nice to Have
- Experience with GraphQL.
- Experience with end-to-end testing.
- Experience working on customer-facing B2C products.
- Experience improving conversion, or purchase-related journeys.
- Exposure to full-stack work beyond the front end.
- Familiarity with tools such as Claude, Cursor, Copilot, or similar AI coding assistants.
What Success Looks Like
Build and improve the experiences that customers use before and after purchase, with a strong focus on speed, quality, and AI-assisted engineering. You will help shape the web and app journeys that directly affect how customers discover deals, complete purchases, and manage their orders.
We Are Interested In
- Candidates who like solving real product problems, not just writing code.
- People who learn quickly and can work through changing priorities.
- Engineers who are proactive, curious, and easy to trust with ownership.
- Candidates who can explain how they think, not only what they have built.
What We Offer
- Impact at scale: Help shape the experiences millions of customers use before and after purchase, with real influence on how the product evolves.
- Ownership, not just delivery: You’ll own key journeys end to end
- AI‑first environment: Full access to AI coding tools, including a Claude Max plan and other approved assistants, integrated into your everyday workflow.
- Flexible working hours and hybrid model
- Attractive bonus and benefits package
- Growth across stacks: Plenty of opportunity to stretch beyond front‑end into full‑stack, testing, and automation.
- Culture of speed and learning: A team that values data‑informed decisions, experimentation, and smart automation over pure process.

About the Role
Senior Full-Stack Engineer — CoreApps Platform (AI-native, Encore)
A builder role on the team that powers Groupon's global commerce engine.
CoreApps Platform is the foundational engineering group powering Groupon's global commerce engine — every customer interaction and every transaction, worldwide. This is a builder role: you take features from problem statement to production across backend, frontend, CI/CD, and test automation, using Claude Code as your daily leverage tool. You own the whole slice. You unblock yourself. You ship.
What You'll Do
- Drive features end-to-end. Backend services, frontend surfaces, CI/CD pipelines, test coverage, deploy, monitor — the whole vertical slice. No handoffs, no "that's someone else's team."
- Ship on legacy and cutting-edge together. Modernize Java / Ruby systems into TypeScript / Node.js on Encore, while keeping services at 100K+ RPM running cleanly.
- Operate Claude Code natively. Daily agentic workflow with MCPs, skills, hooks, evaluation patterns — AI is not a productivity add-on, it's how you collapse FE + BE + DevOps + QA into a single-engineer scope.
- Cut through red tape. Find the path. Kill process that doesn't protect anything. Respect process that does. Escalate when you can't, ship when you can.
- Lift your peers. Share patterns, unblock teammates, leave the codebase cleaner than you found it.
Must Have
- 5+ years shipping production software, with deep production TypeScript / Node.js as your primary backend stack (NestJS / Fastify / Encore or similar, named and used).
- Full-stack range. You've owned features across backend and frontend, and you're comfortable in CI/CD pipelines, test automation, and production debugging. Specialist-only profiles (backend-only, frontend-only) will not fit this role.
- Claude Code native. Daily use with a demonstrable personal setup — MCPs, skills / agents, hooks, or equivalent automation. You can screen-share it. Autocomplete-only and Cursor-only do not qualify.
- Builder bias. Evidence of projects you drove beginning to end — scoped the problem, designed the approach, shipped it, operated it. No "I contributed to…" answers — we want what you built.
- Distributed systems fundamentals — API design, SLOs, structured observability, on-call ownership.
- High-bandwidth communication — written and verbal, across technical and non-technical audiences.
Nice to Have
- Java or Ruby reading fluency (for navigating the source systems being migrated).
- E-commerce / marketplace scale experience.
- Encore, Temporal, or similar workflow frameworks.
- Frontend frameworks used in anger (React, Next.js).
What Success Looks Like
First 30 days: operating in the team's AI workflow on day one — Claude Code setup running, first PR merged, owning a service.
First 90 days: shipped at least one end-to-end feature across the full stack, reduced a real bottleneck, demonstrably faster velocity than traditional backend-IC pace.
First 180 days: the team points to work only you could have driven at that pace — migration cutovers, FE + BE features shipped as single units, tooling peers now depend on.
We Are Interested In
Builders. Engineers who take scope from "this is a problem" to "this is in production" without waiting for permission. Fluent in Claude Code as the force multiplier that makes one engineer effective across backend, frontend, DevOps, and QA. Deep in TypeScript, comfortable anywhere in the stack, energized by cutting through noise and shipping. If you wait to be told what to do, this role will frustrate you.
