Lead UAS Navigation Engineer; SC Cleared

Lead Navigation & PNT Systems Engineer (SC Cleared)
Bristol – 3 days a week onsite
Salary: £ Negotiable + Comprehensive Benefits Package

This is an excellent opportunity for a subject matter expert in Positioning, Navigation, and Timing (PNT) to join a high-impact team at its inception. Whether you are a specialist in Kalman filtering, GNSS resilience, or novel RF positioning, this role offers the chance to redefine how Unmanned Aircraft Systems (UAS) navigate within the most contested and complex environments. The company is building a dedicated Navigation & PNT capability group focused on the development of resilient, high‑integrity technologies.

As a foundational hire, you will be at the forefront of navigation capability, ensuring that our autonomous platforms remain operational even when traditional systems fail.

In this varied role, you will take ownership of the PNT architecture, moving from high‑level design to hands‑on implementation. You will design and simulate advanced algorithms tailored for UAS flight profiles, evaluate system performance in GNSS‑denied environments through flight test analysis, and support the integration of software with high‑grade IMUs and flight control hardware.

• Develop advanced navigation fusion (EKF/UKF) and resilient GNSS algorithms.
• Define modular "Plug and Play" PNT architectures for UAS platforms.
• Conduct GNSS‑denied simulation and Hardware‑in‑the‑Loop (HIL) testing.
• Provide technical authority and roadmap guidance for PNT capabilities.

• Degree‑qualified in Aerospace/Robotics with deep sensor fusion expertise.
• Proven experience in GNSS‑denied navigation (UAS, Missiles, or Robotics).
• Highly proficient in modelling, simulation, and complex error‑budget analysis.
• Must be eligible for UK SC Clearance.

We are an equal opportunities company and welcome applications from all suitable candidates.
