Communications Systems Engineer (SC Cleared) Bristol - 3 days a week onsite £Negotiable + Comprehensive Benefits Package This is an excellent opportunity for a systems-focused Communications Engineer to take ownership of the vital data links that keep Unmanned Aircraft Systems (UAS) connected. Whether your background is in SDRs, Satcom, or Tactical Data Links, this role offers the chance to design end-to-end architectures that ensure seamless command and control (C2) in the most contested environments. This company is at the forefront of UAS innovation, developing platforms that must remain reachable across diverse and complex mission profiles. You will act as the bridge between high-level mission requirements and hardware implementation, selecting the right mix of RF and Military Bearers to ensure mission success and high-bandwidth telemetry. In this varied role, you will move from defining link budgets and sizing hardware (transceivers, antennas, modems) to leading the integration of LOS and BLOS systems. You will oversee the implementation of secure military waveforms and encryption, optimise networking stacks for low-latency aerial links, and lead "on-platform" interference testing to validate link performance. The ideal candidate will possess a background in flight safety and mission data quality, and should be a hands-on problem solver, comfortable troubleshooting RF interference or network dropouts in real-world environments while collaborating closely with Avionics and Airframe engineers. This is a fantastic opportunity to drive the communications roadmap for a next-generation UAS program. From bench-top HIL testing to ground range trials and flight campaigns, you will have the autonomy to define how our aircraft stay connected, ensuring they are never out of reach. The Role: Define RF/Satcom hardware sizing and end-to-end link budgets. Lead LOS/BLOS system integration and secure protocol optimisation. Oversee military-grade waveforms and cryptographic equipment compliance. Execute HIL, EMI/EMC, and flight test campaigns for connectivity. The Person: Previous experience in RF, antenna theory, and modulation schemes. Hands-on experience with SDRs, Satcom, and tactical data links. Preferably a degree in Electrical, Electronic, or Telecommunications Engineering. Must be eligible for UK SC Clearance.

Lead Navigation & PNT Systems Engineer (SC Cleared) Bristol - 3 days a week onsite £ 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. This 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. The ideal candidate will possess a deep technical background in aerospace or robotics. You should be comfortable performing complex error-budget analysis and have a passion for solving the "GNSS-denied" challenge using non-traditional methods like Vision-Based Navigation (VBN) or Terrain Referenced Navigation (TRN). This is a fantastic opportunity to act as a technical authority within the program and work in a collaborative, cross-functional environment, alongside Flight Control and Mission Systems engineers to deliver a cohesive, world-class navigation suite. The Role: 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. The Person: 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.
