Our new flight-control system is already alive and flying. Now we want to make it faster, sharper and more capable.
As our Flight Control & State Estimation Engineer, you will push the performance of our interceptor to the next level. You will improve how precisely it estimates its state, how quickly it reacts and how aggressively it can operate without compromising stability or robustness.
From advanced estimation and control algorithms to embedded Rust optimization and flight-test analysis, your work will have a direct and measurable impact on aircraft performance.
You do not need to cover every discipline equally. We are looking for deep expertise in either state estimation or flight control, and the ability to understand their interaction as one complete system.

The company’s range of electric vertical take-off and landing (eVTOL) sUAS are built to maximize range and versatility and to provide operators with a seamless user experience. By integrating cutting-edge software capabilities, like edge computing and real-time AI-powered data processing, Quantum Systems is building next-generation UAS for clients in the defense, security, and public sectors.
Please include as your cover letter:

Quantum Systems is a leading European deep-tech company specialising in unmanned systems. We develop, produce, and scale integrated hardware, software, and AI solutions that are operational across air, ground, and sea today.
Headquartered near Munich and operating globally, we build all core technologies in-house: platforms, mission software, and AI-driven analytics. This stands for technological excellence, scalability, and European sovereignty.
Armed forces, security agencies, and critical infrastructure operators rely on our systems when situational awareness and speed of decision-making define the outcome.
What we build is already in the field. What we're building next will redefine the category.
We're looking for people who want their work deployed, not presented. Who believe sovereignty is something you engineer, not something you declare.
