## About the role

We're looking for a Software Engineer who builds and operates the AI-native backend systems powering our go-to-market motion. You'll design multi-agent architectures, build reliable integrations across complex business systems, and own services end-to-end from prototype through production.

## What they're looking for

- 2+ years of software engineering experience building backend services in Python
- Production experience building multi-step AI agent systems — stateful workflows where models make decisions, call tools, and operate across multiple turns, not single-shot API wrappers
- Experience testing and evaluating non-deterministic AI systems — you understand that assert output == expected doesn't work and have built or used alternatives
- Solid software architecture fundamentals: API design, state management, fault tolerance, and graceful degradation when upstream services fail
- Production experience with containerized deployments (Docker, Kubernetes) and CI/CD pipelines
- Experience integrating with external APIs at scale — auth flows, rate limiting, retries, data normalization, and managing the operational complexity of multiple third-party dependencies
