Responsibilities

Design, build, and own critical systems of the Fabric Gateway from the ground up — this is founding-level engineering work.
Lead architecture decisions for distributed systems that need to be fast, reliable, and correct at scale — handling high request volumes across a diverse ecosystem of services.
Drive technical direction and make high-leverage decisions; you'll be setting patterns the rest of the team follows.
Own observability, performance, and reliability end-to-end — SLA targets, monitoring, and on-call are your personal responsibility, not a handoff.
Collaborate closely with the EM and PM to scope milestones, prioritize ruthlessly, and iterate toward Early Access and GA.
