ABOUT THE ROLE
Build backend systems and infrastructure for reliable agent execution at a SaaS company.

WHAT YOU'LL DO
- Build backend services and data models to track operational work, ownership, and outcomes over time.
- Develop asynchronous workflows that handle retries, timeouts, external events, and interrupted execution reliably.
- Create shared APIs and tool-execution interfaces with authorization and customer-data isolation.
- Improve how operational knowledge is stored, versioned, and served.
- Strengthen testing and observability as the platform evolves.
- Investigate production issues, design clear interfaces, and deliver maintainable solutions.
WHAT WE'RE LOOKING FOR
- At least 3 years of experience building and maintaining production backend services.
- Practical experience with Python and/or TypeScript/Node.js, and relational databases such as PostgreSQL, including data modeling and transactions.
- Experience with background jobs, queues, or event-driven processing, including failure handling and data consistency.
- Experience designing asynchronous workflows that account for retries, timeouts, external events, and interrupted execution.
- Strong backend fundamentals and the ability to investigate production problems and design maintainable interfaces.
- Experience with workflow engines, multi-tenant applications, authorization, FastAPI, or agent tooling is helpful. Prior LLM experience is not required.
