The Mission: Build the Brains Behind Groupon’s Merchant AI

Groupon is undergoing a massive AI-first transformation, and this role is at its core. We’re building our first intelligent copilot for merchants—a chat-based assistant that can answer their toughest questions, automate deal creation, and redefine our entire partner experience.

As our AI Agent Engineering Lead, you will be the technical architect behind this new agent. You won't just be prototyping; you will architect, build, and ship the foundational agentic system that will power Groupon’s future interactions with our millions of merchant partners.

🚀What You’ll Build & Own

Architect & Build our Merchant AI Copilot: Design and deliver our first agentic chat assistant from the ground up, using Retrieval-Augmented Generation (RAG), callable tools (LangSmith), and live internal data sources.
Connect Real-World Data & Business Logic: Integrate the agent with complex merchant data—performance metrics, payout history, and fees—and encode Groupon’s specific business rules, content policies, and deal lifecycle logic.
Implement Smart, Scalable Architecture: Create robust, structured question-response flows with clear fallback and Human-in-the-Loop (HITL) escalations. Your work will be the scalable foundation for future support bots, onboarding assistants, and deal insight tools.
Deliver with Engineering Excellence: Build and maintain the RESTful APIs and microservices that power the agent, ensuring high performance, scalability, and reliability on our cloud platforms (GCP & AWS).

🔎 Who You Are: The Ideal Candidate

A Proven AI/LLM Builder: You are a hands-on engineer who has built and shipped AI agents or chatbots. You’re fluent in modern agentic patterns like RAG, tool-chaining, and prompt engineering and have connected them to real business data to solve complex problems.
A Pragmatic Software Engineer: With 5+ years of experience, you have a strong background in backend engineering, distributed systems, and microservices. You are a polyglot at heart—your expertise is in building great software, not just in one language.
A Collaborative Leader & Mentor: You thrive in a team environment and are passionate about mentoring others. While this is an individual contributor role to start, you will lead by example, guiding the team on technical decisions and best practices.
A Product-Minded Problem Solver: You understand how to translate messy, real-world business needs into clean, effective technical solutions. Experience in marketplaces, e-commerce, or B2B SaaS (especially seller/merchant platforms) is a huge plus.
