You'll work on complex, high-scale systems that enable merchants to optimize payment performance while building secure, extensible infrastructure for the future of payments.
You'll collaborate closely with Product, AI, and Engineering teams, mentor junior engineers, and play a key role in shaping the architecture of a platform used by substantial enterprise customers.

Collaborate closely with other service owning teams to integrate via APIs and real-time data streams, ensuring seamless data flow across the stack & overall platform
Raise the bar: Lead code reviews, champion backend standards, and drive architectural decisions that keep the codebase healthy as we scale.
Multiply the team: Mentor engineers around you and elevate backend engineering quality across the organization through pairing, documentation and leading by example.
Own the full lifecycle: Work across requirements, implementation, testing, and deployment. We don't throw things over the wall here.
