## Requirements

- 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.

## Description

### **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.
