Navigation Engineer, Precise PNT & Sensor Fusion

Harmattan AI; Paris; On-site; EUR 90,000 - 130,000; Full time

Job summary

Harmattan AI in France is seeking a Navigation Engineer to design high-precision navigation and positioning solutions using tightly-coupled IMU/GNSS filtering, improving localisation accuracy and robustness to jamming. You will collaborate with the Navigation, Radar, software and EW teams to deliver robust PNT and ensure performance in field deployments.

This role requires strong mathematical background and experience with GNSS/INS filtering, system-level design reviews, and clear documentation.

Qualifications

• Strong mathematical background with solid physical intuition.
• Experience with GNSS, INS/IMU and navigation/estimation filters (Kalman) in tightly-coupled architectures.
• Experience navigating GNSS-denied or contested environments.
• Familiarity with RF and EW constraints (GNSS jamming / spoofing).
• Solid software / algorithm skills; combined algo + software profile.
• MSc in Engineering (aerospace, robotics, EE or related); PhD is a plus.
• Broad engineering culture across electrical, embedded and mechanical systems.
• Rigorous, structured and mission-driven mindset with analytical skills.
• Excellent communication and documentation abilities.

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.
• 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.
