Senior Engineer - Fabric Gateway

Postman Postman · Enterprise · Bangalore, India · Product Engineering

This role is for a Senior Engineer to build the Fabric Gateway, a new product acting as a policy-driven control plane for how AI agents connect to APIs, services, and each other. It's a 0-to-1 infrastructure product focused on the runtime layer for agent interactions within the Postman ecosystem.

What you'd actually do

  1. Design, build, and own critical systems of the Fabric Gateway from the ground up — this is founding-level engineering work.
  2. 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.
  3. Drive technical direction and make high-leverage decisions; you'll be setting patterns the rest of the team follows.
  4. Own observability, performance, and reliability end-to-end — SLA targets, monitoring, and on-call are your personal responsibility, not a handoff.
  5. Collaborate closely with the EM and PM to scope milestones, prioritize ruthlessly, and iterate toward Early Access and GA.

Skills

Required

  • 6+ years of experience building infrastructure-level or platform software in cloud-native or SaaS environments.
  • Proven 0-to-1 track record — you've taken something from whiteboard to production and operated it at scale.
  • Deep systems design expertise: you've built distributed systems that handle high throughput, stay resilient under load, and scale horizontally without breaking operational simplicity.
  • Proficiency in Go.
  • Strong fundamentals in systems programming and performance-sensitive code are essential.
  • Solid grasp of security primitives: mTLS, JWT, OAuth 2.0, RBAC/ABAC.
  • High ownership mindset — reliability, performance, and security are your problem, not someone else's ticket.
  • Strong communication skills; comfortable driving clarity in fast-moving, ambiguous environments.

Nice to have

  • Prior experience building or extending platform or gateway products.
  • Familiarity with modern protocol ecosystems (HTTP/2, gRPC, WebSockets).
  • Kubernetes-native deployment experience: Helm, operators, CRDs.
  • Contributions to open-source infrastructure or developer tooling projects.
  • Experience working in an early-stage 0-to-1 environment inside a larger company.
