Autonomous defense systems and C2 platforms
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.
As 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.
MSc in Engineering (aerospace, robotics, EE or related); PhD is a plus.
Strong mathematical background combined with good physical intuition.
Experience with GNSS, INS/IMU and navigation/estimation filters (e.g. Kalman filtering), particularly in tightly-coupled architectures.
Experience with navigation in GNSS-denied / contested environments.
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.
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.
Autonomous defense systems and C2 platforms
Harmattan AI builds vertically integrated autonomous defense systems for NATO and allied forces. Its products include layered air defence, coordinated ISR and strike UAVs, electronic-warfare tools, and command-and-control platforms, all powered by a software-defined autonomy stack. The systems are designed to operate together, with autonomous decision-making, sensor fusion, and mission execution through its C2 framework. The company differentiates itself through large-scale industrial manufacturing, secured Programs of Record with European and UK defense ministries, and a strategic partnership with Dassault Aviation to embed Harmattan’s controlled autonomy into combat-air systems such as Rafale F5 and UCAS. The goal is to provide trusted, scalable autonomous solutions for defense missions, expanding globally and embedding autonomy into partner platforms to strengthen allied capabilities.
