About the role

APIs are how software talks to software, and the volume and variety of that traffic is growing rapidly. AI agents now discover and call APIs directly, and MCP servers are a new kind of endpoint with the same questions attached: what exists, what it's supposed to do, and who is allowed to call it. Enterprises are challenged to respond to those questions. This role owns Fastly's answer.

What they're looking for

  • Experience: 5+ years in product management or technical product leadership, ideally on API, security, or platform infrastructure products
  • Platform thinking: a track record of building capabilities that serve more than one product or team. Shared primitives, enforcement points, or controls others build on, rather than features scoped to a single surface
  • Execution focus: a demonstrated bias for shipping. You are hands-on and comfortable owning outcomes in ambiguous, fast-moving conditions rather than waiting for perfect clarity
  • Hands-on work with API gateways and OpenAPI-driven validation: schema generation from live traffic, drift detection as APIs change, and the gap between the spec a team publishes and what their API actually does
  • The agentic traffic stack — workload and agent identity (SPIFFE/WIMSE, mTLS), OAuth 2.1 for delegated agent authorization, and agent protocols like MCP and its authorization spec
  • Request-path enforcement at scale: WASM filters, eBPF, or policy engines like OPA and Rego
