Backend / Systems Engineer, Agent Infrastructure

ABOUT THE ROLE

Build backend systems and infrastructure for reliable agent execution as part of a SaaS engineering team. You will take ownership of foundational architecture for persistent state, safe execution, permissions, and recovery, connecting people, agents, and external systems.

WHAT YOU'LL DO

• Build backend services and data models that track operational work, ownership, and outcomes over time.
• Develop asynchronous workflows that reliably handle retries, timeouts, external events, and interrupted execution.
• 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 backend engineering experience building and maintaining production services.
• Practical experience with Python and/or TypeScript/Node.js, and willingness to work across both.
• Experience with PostgreSQL or another relational database, including data modeling and transactions.
• Familiarity with background jobs, queues, or event-driven processing, including failure handling and data consistency.
• Experience building resilient asynchronous workflows and investigating production problems.
• Experience with workflow engines, multi-tenant applications, authorization, FastAPI, or agent tooling is helpful. Prior LLM experience is a plus, not a requirement.
