• Drive architectural and design decisions for ticketing event management, ticket checkout (digital presale and POS), reserved-seating systems, redemption flows and concessions. • Collaborate with peer Staff Engineers in Shared Services and Fintech, as well as engineering managers and product leaders, to co-define priorities, surface trade-offs, and run proofs-of-concept for new directions. • Lead major initiatives such as: migrating microservices from ECS and Lambda to EKS; optimizing performance for high-volume ticket transactions; resolving data-model alignment between ticketing and other domains; improving consistency and maintainability of frontend and backend stacks. • Drive observability, automated governance and cross-surface reliability (web/mobile/backend) under load. • Mentor senior engineers and contractors, lead design review forums, own major RFCs, refine engineering process (CI/CD, load testing, monitoring). • Work with external vendors and partners (payment providers, reserved-seating / scanning hardware, POS integrations), evaluate technical risk, and drive vendor-agnostic solutions that support our scale and flexibility goals.
