Backend / Systems Engineer, Agent Infrastructure

Stellenbeschreibung:

About the Role

Build the backend systems and infrastructure that support reliable agent execution at an early-stage SaaS company. Working with the technical leadership and AI engineering team, you will own foundational architecture for persistent state, safe execution, permissions, and recovery.

What You'll Do

Build backend services and data models to 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.
Experience with background jobs, queues, or event-driven processing, including failure handling and data consistency.
Strong backend fundamentals and experience designing reliable asynchronous workflows.
Experience with workflow engines, multi-tenant applications, authorization, FastAPI, or agent tooling is a plus. Prior LLM experience is not required.
