Principal Robotics Engineer - Autonomy & Behavior in München

What we’re looking for

The day-to-day

• Own the behavior layer: design the nodes, the ports, and the structure that makes a flight readable and testable as data rather than as code.
• Move the remaining flight authority out of hand-written logic and into the tree, and prove that the new path behaves like the old one before we delete the old one.
• Define how the companion computer asks the autopilot for a flight skill, and how it reads back whether that skill is running, finished, or refused.
• Draw the line between what is shared across robots and what each robot writes for itself, so that a second platform reuses the stack instead of forking it.
• Make failures legible: a log and a trace should tell a reader which check said no, and why.
• Work across the autonomy, perception, platform, and testing teams, since the behavior layer touches all of them.
• Raise the technical bar: design reviews, code reviews, and the written arguments that go with them.
• Mentor engineers, without holding a management line.

You should apply if you

• Have around 5 years or more of robotics software experience. Leadership experience is not required.
• Have deep C++ expertise, and the judgment to design a system that other people will extend.
• Have real experience with behavior trees, or with another explicit way of expressing robot behavior, and clear opinions about where that approach breaks.
• Have a breadth of knowledge across robotics: state estimation, motion planning, control, or perception. Depth in at least one of them.
• Have Experience withrobotsthatrun in the physicalworld, not only in simulation.
• Possess the ability to take a design apart in a discussion and put it back together bette

Nice to haves

• Experience with PX4, ArduPilot, orMAVLink, and with the split of workbetween an autopilot and a companioncomputer.
