Senior) Navigation Engineer (m​/f​/d

At Quantum Systems, we develop cutting‑edge unmanned aerial systems that redefine what autonomous flight can achieve. Our mission is to deliver highly reliable, mission‑ready UAV solutions for governmental and professional applications worldwide. To further strengthen the performance and resilience of our platforms, we are looking for a passionate and experienced Navigation Engineer (m/f/d) who is eager to push the boundaries of GNSS/INS‑based navigation in complex and challenging environments.

• Conceptualize, design, implement, and validate GNSS/INS navigation algorithms: state estimation, sensor fusion, and fault handling in line with project requirements.
• Analyze real flight data to diagnose complex issues, drive root‑cause analysis, and implement robust algorithmic and software improvements.
• Refactor and generalize existing navigation modules to further improve our robustness in challenging environments.
• Participate across the full system development lifecycle: concept, design, prototyping, flight testing, and operations support.
• Lead technical discussions and contribute to architecture decisions, design reviews, interface definitions and system documentation.
• Collaborate closely with multidisciplinary teams including flight control and embedded software engineers, systems engineers and test engineers.
• Improve navigation performance through sensor characterization and calibration.
• Drive technical decisions within the navigation domain and support code reviews and mentoring as needed.

• M.S. in Robotics, Aerospace engineering, Computer Science, Electrical, Mechanical, Mechatronics or related field.
• Multiyear professional experience in navigation and/or sensor fusion for robotics or UAVs (GNSS/INS strongly preferred).
• Strong theoretical and practical expertise in estimation and filtering techniques (e.g., EKF, Factor Graphs, etc.).
• Solid understanding of fixed‑wing and multirotor flight dynamics and flight mechanics.
• Proven ability to take ownership in complex systems: working independently, driving technical decisions and delivering results end‑to‑end.
• Ability to quickly understand and extend complex systems and established codebases.
• Strong programming skills: proficiency in MATLAB/Simulink and at least one of Python, C++, or Rust (proficiency in all three is a plus).
• Fluent in written and spoken English.

• We believe in the power of combined efforts: straightforward tech expertise paired with a customer‑centric focus.
• We are industry pioneers who are ambitious, bold, and visionary.
• We push limits, think outside‑the‑box and strive for technological excellence to shape the future of aerial data.
• We promise to be your runway for individual and professional growth.

• Company pension scheme: we support you so that you can already make provisions for later.
• Flexible working hours: with trust‑based hours you are responsible for your work‑life balance.
• Mobile working: if it gets too turbulent for you in our office, you can work from wherever you need.
• Bike‑leasing: we support you in staying environmentally mobile and healthy.
• Corporate benefits: attractive offers and discounts from well‑known suppliers and brands, e.g., Adidas, Apple, Expedia.
• Employee events: we celebrate successes together.
• Lunch card: a daily lunch budget is sponsored.
• Company shuttle: convenient shuttle service picks you up from Pasing in Munich and brings you to our location, with return trips at the end of the workday.
