About the job
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.
ABOUT US
Most AI is frozen in place - it doesn't adapt to the world. We think that's backwards. Our mandate is to build efficient intelligence that evolves in real-time. Our vision is AI systems that are flexible, personalized, and accessible to everyone. We believe efficiency is what makes this possible - it's how we expand access and ensure innovation benefits the many, not the few. We believe in talent density: bringing together the best and most driven individuals to push the boundaries of continual adaptation. We're looking for builders and creative thinkers ready to shape the next era of intelligence.
BENEFITS
- Flexible work: In-person collaboration in the Bay Area, a distributed global-first team, and team offsites.
- Adaption Passport: Annual travel stipend to explore a country you've never visited. We're building intelligence that evolves alongside you, so we encourage you to keep expanding your horizons.
- Lunch Stipend: Weekly meal allowance for take-out or grocery delivery.
- Well-Being: Comprehensive medical benefits and generous paid time off.
