Job description

The role

As a Product Engineer at calliora, you don't just write code, you build. You take a real problem and turn it into something that ships. You build the platform that lifts the manual work off the hospital: the agents that carry a case end to end, the infrastructure they run on, and the product clinicians and administrators actually use. The agents do the work themselves, with full context and without waiting for anyone to log in, not a copilot sitting beside someone clicking through screens. We work fast and hands-on, but what we ship runs in hospitals, one of the most regulated environments there is. Speed is how we find the right product. Rigor is how we earn the right to run it.

Examples of what you might ship

• An eval harness that regression-tests every prompt and model change against golden cases before it ships
• The abstention logic that decides when an agent acts on its own and when it stops and asks a human
• A replay layer that makes agent runs deterministic, so you can debug a bad case exactly as it happened

Your Responsibilities

• Building, not just coding: owning a problem from the first conversation about it through prototype to running in production.
• Developing the agents that carry cases through real clinical-administrative workflows, and the infrastructure they run on.
• Building the product that clinicians and administrators touch every day.
• Prototyping quickly and iterating together; we don't write specs and hand them off, the best version becomes the product.
• Shipping at production quality for a regulated environment: tested, observable, secure.
• Talking to the people who use what you develop and turning what you learn into product decisions.

What We Look For

We hire for trajectory, not credentials alone. We've hired people early in their careers who taught themselves and proved it. What matters is what you've built.

Ideal Candidate Profile:

• You think in product, not tickets. You form opinions about the user and the problem, you want to talk to the people who use what you develop, and you push back when something is wrong.
• Excellent engineering, from blank file to working product, cleanly and fast. Testing, observability, and security are not afterthoughts for you.
• You push the frontier, in the product you build and in how you build it. When a new capability shows up, you're already using it.
• Comfort across the stack: frontend, backend, infrastructure, ML. You've proven you can work in several of these and pick up the rest fast. Strong fundamentals matter more than matching our exact tools.
• High self-drive and end-to-end ownership: you ship without being asked twice.
• Very good written and spoken German.

What We Offer

• Real ownership from day one: the hard problems, end to end, with the people closest to them. Meaningful equity, so you own a real piece of what you build.
• Competitive salary in one of Europe's most ambitious AI companies.
• A flat structure and direct access to the founders, where your work shapes both the company and the product.
• An exceptional team that holds a high bar and values action, clarity, and craft.
• A frontier worth your career: making the operational backbone of European healthcare dramatically better.

Location & Logistics

• Based in Munich, primarily in-person.
• Full-time, permanent. Start as soon as possible.

About Us

calliora is building the AI operating layer for hospital economics. Hospitals deliver care when it matters most, but documentation, coding, review and reimbursement move across teams and systems that rarely share the same context, and too much of the value of that care gets lost along the way. Our technology carries every case from admission to reimbursement: it connects the context, takes on the routine work, brings in human expertise where judgment makes the difference, and closes each case at its full worth. A double-digit number of hospitals already run calliora in production. Founded by AI researchers and backed by healthcare-industry veterans and top-tier investors, we're an ambitious, in-person team in Munich, looking for people who want to do the hard, exact work that keeps hospitals running.
