Platform Engineer, APIs and Security

The Role

You'll build the multi-tenant platform that turns our inference infrastructure into a product enterprises and sovereign customers can trust.

You'll own the systems between customers and our inference stack: authentication, tenant isolation, quotas, metering, entitlements, and the public API. Security and auditability are core product requirements, not layers added later.

Responsibilities

• Build the multi-tenant control plane, including credentials, quotas, rate limits, and tenant isolation.
• Own our public inference APIs, including streaming, versioning, compatibility, and migrations.
• Implement accurate usage metering, credit reservation, and entitlement enforcement.
• Build enterprise capabilities such as SSO, access controls, audit logs, and data residency.
• Test and continuously strengthen the tenant boundary.

Qualifications

• 5+ years in backend, infrastructure, or platform engineering, including ownership of a multi-tenant API or control plane.
• Deep knowledge of authentication, credential management, rate limiting, quotas, and tenant isolation.
• Strong Python skills and sound API design judgment, ideally with high-throughput or streaming APIs.
• Experience with metering, billing, credits, or entitlements, including idempotency, reconciliation, and audit trails.
• Experience with enterprise or regulated environments, such as SSO, SAML/OIDC, SOC 2, data residency, or sovereign deployments.

Above all, we're looking for great teammates who make work feel lighter and aren't afraid to go out on a limb with bold ideas. You don't need to be perfect, but you do need to be adaptable. We encourage you to apply, even if you don't check every box.
