Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.
Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.
About the RoleAs a Navigation Engineer within our Precise Navigation team, you will design and develop high-precision navigation and positioning solutions based on tightly-coupled IMU/GNSS filtering, improving localisation accuracy, integrity, and robustness to jamming and spoofing for our autonomous systems – from concept to field deployment. You will work hand-in-hand with the Navigation and Radar teams, as well as software and Electronic Warfare (EW) teams, to deliver robust, resilient Position, Navigation and Timing (PNT) and ensure overall performance, robustness and reliability.
Navigation Architecture: Drive the architecture and implementation of navigation / PNT solutions for autonomous platforms.
Resilient PNT: Develop navigation resilient to GNSS degradation, jamming and spoofing (anti-jam / anti-spoof).
Sensor Fusion: Design multi-sensor fusion (GNSS, INS/IMU, RF, vision) and the associated estimation and filtering algorithms.
Testing & Validation: Design test plans (e.g. GNSS receiver testing in jamming environments), run simulations and replays, and report on findings and performance against targets.
Technical Coordination: Collaborate across HW, software, EW and ML teams on technical interfaces and system-level trade-offs.
System Reviews & Documentation: Contribute to design and architecture reviews and maintain requirements traceability and documentation.
Strong mathematical background combined with good physical intuition.
Experience with GNSS, INS/IMU and navigation/estimation filters (e.g. Kalman filtering) is a strong plus, particularly in tightly-coupled architectures.
Experience with navigation in GNSS-denied / contested environments is a strong plus.
Familiarity with RF and EW constraints (GNSS jamming / spoofing) is a plus.
Solid software / algorithm skills; combined algo + software profile rather than a pure coder.
MSc in Engineering (aerospace, robotics, EE or related); PhD is a plus.
Broad engineering culture with understanding of electrical, embedded and mechanical systems.
Rigorous, structured and mission-driven mindset with strong analytical skills.
Excellent communication and documentation abilities.
We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
