Platform Engineer, APIs and Security
About this role
Build the foundational multi-tenant platform that secures and controls access to inference infrastructure for enterprise customers.

- Own public inference APIs including streaming, versioning, compatibility, and migration strategies
- Build accurate usage metering, credit reservation, and entitlement enforcement systems
- Implement enterprise features like SSO, SAML/OIDC, access controls, audit logs, and data residency
- Test and continuously strengthen tenant boundaries to prevent data leakage
- Ensure idempotency, reconciliation, and audit trails across billing and entitlement systems
What they're looking for
- Backend or platform engineering (5+ years)
- Multi-tenant API and control plane architecture
- Authentication and credential management
- Rate limiting, quotas, and tenant isolation patterns
- Python programming
- High-throughput and streaming API design
- Metering, billing, and entitlement systems
- Enterprise security (SSO, SAML/OIDC, SOC 2, data residency)
Benefits
