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
📍Hybrid from Madrid or Valencia
You will engineer the core of our proprietary internal platform that democratizes AI across the company. This is not a standard full-stack role maintaining existing systems, you will build the factory that enables other teams to create autonomous AI Agents. You will design Chain of Thought reasoning flows, integration layers, and agent logic that allow AI to execute complex business tasks at scale. This is applied AI engineering: no model fine-tuning, just sophisticated system design and relentless execution. You will join a new focused team of two engineers, collaborating daily with the AIGO team and cross-functional partners across Global Operations, Customer Satisfaction, and Engineering.
Key Responsibilities
- Develop and expand our internal AI platform, enabling internal teams to build autonomous AI Agents without deep ML expertise
- Engineer Chain of Thought reasoning flows and integration layers that power agent logic
- Build reliable, long-running AI Agent systems that handle failures at scale and prevent cascading outages when external LLM providers go down
- Design node-based tools for intent retrieval, context management, and API routing
- Program agent logic using TypeScript, Node.js, Express, React, Next.js, and SQL
- Maintain a high bar for software quality and reliability while innovating at speed
- Integrate AI-native tooling (Cursor, Claude Code) into your development workflow without sacrificing code quality
Key Requirements
- Experience with TypeScript, Node.js, Express, React, Next.js, and SQL
- Practical knowledge of Docker, Kubernetes, and Linux environments
- Hands-on experience with Chain of Thought (CoT), Agent building, and RAG concepts
- An AI-First mindset: you already use Cursor or Claude Code and possess the engineering rigor to validate AI-generated code
- Proven track record of shipping software to production
Nice to Have
- Proficiency with Cursor or Claude Code
- Knowledge of ML theory (helpful for context, though fine-tuning is not part of the role)
What Success Looks Like
First 30 days: Set up your development environment, adopt AI-first workflows, gain a functional understanding of our internal AI platform, ship a bug fix to production, and build your first AI Agent using our platform.
First 60 days: Deep dive into a key product area’s architecture, design and implement a small-scale AI feature, and demonstrate independence in troubleshooting and shipping without hand-holding.
First 90 days: Take ownership of a significant AI feature from concept to production, contribute to internal documentation on Agent best practices, and actively participate in architectural reviews as a fully integrated team member.
One year: Transform a portion of our AI platform with a major AI-driven application feature, become recognized as a stakeholder in building and optimizing AI Agents across Groupon, and maintain a high bar for software quality while innovating at speed.
We Are Interested In
A true builder who wants to engineer the platform that powers AI Agents, not just write prompts. You bring a balance of “Old School” engineering discipline (reliability, structure) and “New Wave” AI agility. You are excited to use the latest AI-native stack to create sophisticated internal tools that drive global operations and shape how a global company operationalizes AI.

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.

-
Set and enforce engineering standards — code quality, CI/CD pipelines, microservices patterns, and incident response
-
Participate actively in architectural decisions, design reviews, and technical direction within your team's scope
-
Champion AI/ML integration where it delivers measurable outcomes — intelligent routing, automation, personalization; target at least 2 AI-driven features shipped per year
-
Own hiring across your team: sourcing, interviewing, onboarding, and ongoing development
Key Requirements
-
Hands-on software engineering and leadership experience
-
Hands-on background in Java and distributed systems; comfortable reviewing architecture and code when needed
-
Proven experience managing platform or communications infrastructure at scale in a microservices, cloud-native environment
-
Strong AI-First approach and working knowledge of AWS or GCP; familiarity with Kubernetes, Terraform, and messaging systems (Kafka, RabbitMQ)
-
Experience leading geographically distributed teams across time zones
-
Demonstrated ability to manage ambiguity, balance competing priorities, and deliver in fast-moving environments
-
Track record of performance management, career development, and team building
