Role overview
A senior backend engineer is needed to help shape and grow both the open source and cloud versions of a platform used to run production AI agents and workflows. The managed cloud service auto-scales customer code from zero to high throughput, currently handling hundreds of millions of monthly executions for thousands of teams building AI applications. This is a high-impact role that blends hands-on engineering with strategic influence on architecture and roadmap.

- Build backend systems that meet production standards for reliability, throughput, and durability
- Design and implement API endpoints and services that handle real customer traffic
