Navigation Architect for GNSS-Denied Autonomy (EW)

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

Job summary

Harmattan AI is seeking a Navigation Engineer within its EW team to design and implement robust PNT solutions for autonomous platforms operating in contested environments. You will collaborate with HW, SW, and ML teams to ensure accuracy, reliability, and GNSS-denied capability while maintaining clear documentation.

Strong background in navigation, sensor fusion, and real-time estimation is essential; MSc or PhD is a plus.

Qualifications

• 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.

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.
