83 Position, Navigation and Timing Engineer

• What You’ll Do
• Architect and develop multi-sensor state estimation systems (e. g. Kalman filters) for mission‑critical navigation
• Design and implement the full navigation software pipeline, from sensor ingestion to fused state output
• Develop GNSS navigation solution in contested or GPS‑denied environments
• Build solutions robust to non‑ideal conditions: sensor drift, noise, bias, dropouts, and adversarial environments
• Fuse data from non‑GNSS sources (e. g. IMU, vision, radar, altimeters, etc.) to maintain navigation accuracy in GPS‑denied environments
• Deliver deterministic, real‑time software suitable for flight‑critical systems
• Define and execute validation frameworks, including simulation and Hardware‑in‑the‑Loop (HIL) testing
• Establish navigation system interfaces and APIs, ensuring clean integration with guidance, control, and flight software
• Model system‑level failure modes and implement fault‑tolerant designs (e. g. FMEA‑driven architecture)
• Work closely with GNC, software, hardware, and integration teams to ensure system performance under real constraints
• Iterate rapidly using test data to improve robustness and reliability

Who You Are

• An experienced PNT or GNC Engineer with a strong record of delivering real, deployed hardware.
• Expertise in state estimation under real‑world conditions (e. g. Kalman filtering with drift, bias, and noise)
• Proven experience delivering hard real‑time, deterministic software systems
• Strong understanding of system‑level failure modes and fault modelling (e. g. FMEA in complex systems)
• Experience with GNSS‑denied or degraded navigation systems
• Background in aerospace, defence, robotics, or autonomous systems
• Experience integrating multi‑modal sensors (IMU, vision, radar, Li DAR, etc.)
• Familiarity with trajectory generation, guidance, or control systems
• Experience with simulation, HIL testing, or flight validation
• Understanding of safety‑critical software architecture and standards
• You’ve built systems that work outside the lab, not just in theory
• You are comfortable working with imperfect data and hard constraints
• You combine mathematical depth with engineering pragmatism
• You take ownership and deliver, even when problems are ambiguous
• You care about correctness, robustness, and real‑world performance

What We Offer

• A mission‑driven environment with the opportunity to work on one of Europe’s most consequential defence challenges, with direct impact on sovereign capability and security.
• Daily collaboration with top experts across engineering, operations, and defence, with real opportunity to learn from the best, contribute, and grow.
• High ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes.
• A fast‑paced environment where good ideas are implemented quickly, and feedback from test and flight drives real decisions.
• A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly.
• Competitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy.
