We are seeking a foundational engineer to own our single greatest strategic asset: our unique, privileged access to network-level intelligence via the GSMA CAMARA API standard. Own and build the Security Signal Ingestion path, the secure, low-latency, and out-of-band data channel connecting to our founding members' network API gateways. Ensure all network API integrations meet the stringent P99 latency budgets (e.g., < 150ms) required to support our sub-500ms Time-to-Trust product goal. Collaborate with the platform team to build a parallel development path using mocked data to mitigate risks of network API delays. Deep understanding of API design (REST, gRPC, Webhooks) and API security (OAuth 2.0, mTLS, JWTs).
