Backend / Systems Engineer, Agent Infrastructure (m/f/x)

Requirements

What Makes You a Great Fit

• Strong backend engineering skills in Python and/or TypeScript/Node.js, with willingness to work across both.
• Practical experience with PostgreSQL or another relational database, including data modeling and transactions.
• Experience shipping and maintaining production backend services.
• Familiarity with background jobs, queues, or event-driven processing, and an understanding of failure handling and data consistency.
• The ability to investigate production problems, design clear interfaces, and deliver maintainable solutions.

Around 3+ years of backend engineering experience is a useful guide, not a hard requirement. The systems you've owned matter more than the number.

Nice to have: experience with workflow engines, multi-tenant applications, authorization, FastAPI, or agent tooling. Prior LLM experience is not required. Strong backend fundamentals and an interest in learning the agent domain matter more.

You May Not Be a Great Fit If

• You want to configure infrastructure, not design the systems underneath it.
• You need a fully scoped spec instead of investigating ambiguous problems yourself.
• You've never shipped and maintained a production backend service.
• You favor clever or complex solutions over simple, maintainable ones.
• You're looking for a defined 9-to-5.

Benefits

Why Join xHeron

• Real ownership: you're working on foundational product architecture, not cloud configuration, with substantial technical ownership from day one.
• Direct founder access: you'll work directly with our CTO, shaping how humans and agents work together.
• We invest in our own: your ownership grows as the system does, this isn't a role with a ceiling.
• Upside: VSOP alongside salary; you're building this with us.

Our Process

• Intro call (30 min): a conversation with Friedrich (CTO) about your background, what you've built, and why this role.
• Technical take-home case study: a short, real engineering problem, close to what you'd actually be building.
• Case study interview (1 hour): you walk us through your thinking, not just the final code.
• Culture fit (30 min): meet both Founders and make sure it's a fit both ways.
