• 5+ years of experience in avionics navigation systems engineering.
• Hands-on experience with GPS/GNSS-based navigation systems.
• Strong understanding of GPS, GNSS (GPS, Galileo, GLONASS, BeiDou) and related navigation technologies.

Responsibilities

• Design, develop, integrate, and validate GPS/GNSS-based navigation solutions for airborne systems.
• Develop navigation algorithms utilizing GPS, GNSS, INS, AHRS, IMU, air data, radio navigation sensors, and sensor-fusion techniques.
• Perform system requirements development, decomposition, traceability, and verification.
• Support architecture development for integrated avionics and navigation systems.
• Analyse navigation performance, integrity, continuity, availability, and accuracy requirements.
• Evaluate navigation system behaviour in challenging RF environments, including jamming and spoofing conditions.
• Develop system-level test plans, procedures, and verification reports.
• Execute laboratory, simulation, hardware-in-the-loop (HIL), and flight-test activities.
• Support integration with Flight Management Systems (FMS), Multi-Mode Receivers (MMR), Terrain Awareness Systems, and Autopilot/Flight Director systems.
• Conduct failure modes analysis, safety assessments, and fault-tree analysis.
• Review and analyse customer and regulatory requirements.
• Collaborate with software, hardware, systems, verification, certification, and flight-test teams.
• Support FAA, EASA, and military certification activities.
• Participate in technical design reviews and customer presentations.
