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.

Responsibilities

  • 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.

Requirements

  • 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.
