Job Description:

Join the CoreApps Platform team, the foundational engineering group at Groupon responsible for the global commerce engine. Our platform handles every customer interaction and transaction worldwide. This is a high-impact, senior-level Individual Contributor (IC) role with a dual mandate: ensuring KTLO stability at massive scale and accelerating a major platform modernization effort using an AI-first approach. You will own mission-critical services that handle 100,000+ Requests Per Minute (RPM) and champion the shift from legacy Java/Ruby systems to a cutting-edge TypeScript/Node.js microservices architecture, leveraging state-of-the-art AI coding tools to achieve unprecedented speed and quality.

Job Responsibility:

  • Architect and Develop high-throughput, low-latency Core Platform services (e.g., API Gateway, Deal Catalog, User Identity)
  • Drive Modernization by actively refactoring and migrating critical services from legacy stacks to a modern TypeScript/Node.js microservices architecture
  • Champion AI-Assisted Development by leveraging AI coding tools (e.g., Copilot, Cursor) to accelerate feature delivery, navigate complex codebases, and mentor team members on best practices
  • Ensure Operational Excellence for global, production systems, including incident response, system resilience design (circuit breakers, retry logic), and participation in the on-call rotation
  • Design Distributed Systems that are fault-tolerant, self-healing, and resilient, including sophisticated caching and rate-limiting strategies
  • Own Complex Commerce Logic for financial systems, order management, and payment processing within the platform

Requirements:

  • 6+ years of professional backend software development experience (or 3+ years with proven, exceptional AI-driven impact)
  • Strong professional experience in building backend systems with TypeScript and Node.js
  • Mandatory: Proven track record using AI coding tools (e.g., Cursor, GitHub Copilot, Claude Code) to successfully deliver production features and refactor complex, multi-service codebases
  • Proven experience designing and building high-throughput distributed systems (e.g., handling 100K+ RPM)
  • Strong understanding of microservices, event-driven architecture (e.g., Kafka), and transactional systems
  • Proficiency with SQL/NoSQL databases (MySQL/PostgreSQL, MongoDB) and leveraging Kubernetes in a cloud environment (GCP/AWS)

Nice to have:

  • Prior experience with Java, J2EE, or Ruby (to aid in migration/refactoring)
  • Familiarity with complex e-commerce or marketplace platform logic
  • Knowledge of modern orchestration patterns (e.g., Temporal)
  • Deep expertise in cloud infrastructure and services (GCP/AWS)
