## Description

### About the Role

As a Software Engineer on the Model Routing & Inference team at Cursor, you'll build the inference platform that powers every AI interaction in the product.

This team owns the full inference path: making Cursor's AI faster, more reliable, and more cost-effective at a scale few teams in the world get to operate at. Every agent session, every tab completion, and every chat message flows through your stack.

### Example Projects Include...

- Building and evolving our inference gateway, a single abstraction over every provider's API semantics, so model onboarding becomes a config change.

- Designing intelligent cross-provider failover so no single provider outage causes user-visible degradation.

- Designing routing backpressure and admission control so traffic spikes don't cascade into providers.

### You May Be a Fit If...

- You have deep experience building high-throughput, low-latency distributed systems, especially in inference serving, traffic routing, or real-time data pipelines.

- You're comfortable reasoning about cost/performance tradeoffs at scale (GPU utilization, provider economics, capacity planning).

- You have strong software engineering fundamentals and enjoy shipping production systems that handle millions of requests.

- You make good calls in the gray area: weighing reliability, cost, latency, and user experience when there isn't a single 'right' answer.
