ABOUT US
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 ROLE
As a Navigation Engineer within our Electronic Warfare (EW) team, you will design and develop the navigation and positioning solutions that keep our autonomous systems operational in contested and GNSS-denied environments – from concept to field deployment. You will work hand-in-hand with hardware, software, GNC and ML teams to deliver robust, resilient Position, Navigation and Timing (PNT) and to ensure overall performance, robustness and reliability.
RESPONSIBILITIES
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.
Integration & Validation: Oversee integration, prototyping and field validation against performance 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.
CANDIDATE REQUIREMENTS
Strong background in navigation systems (GNSS, INS/IMU) and sensor fusion.
Solid experience with estimation and filtering (e.g. Kalman filtering) and real-time implementation.
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.
