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.

4D Planner (BPSS Clearance) Manchester (Hybrid) Salary (DOE) + Training + Development + Pension + Life Insurance An excellent opportunity awaits a 4D Planner looking to work on complex infrastructure and utilities programmes, combining planning expertise with digital construction and visual planning tools. This role sits within a growing consultancy offering exposure to major projects, modern planning technology and genuine progression. This company is a growing digital consultancy operating across major infrastructure projects, with a strong focus on the digital tools and technology they develop to strengthen project controls and delivery in highly regulated sectors. In this role you'll be embedded within a complex infrastructure project, developing and maintain 4D planning models that link programme schedules with construction sequencing and visualisation. You'll help translate traditional schedules into clear visual simulations that improve understanding of build methodology, sequencing and delivery risk across large programmes. This role is hybrid, based 3 days on-site in Nottingham and 3 days remote. The ideal candidate will come from a planning, engineering or digital construction background within infrastructure, utilities or other complex project environments. You'll have experience working with 4D planning tools such as Synchro 4D or similar technologies, alongside a solid understanding of construction sequencing and programme logic. Experience working with schedules produced in Primavera P6 or similar planning platforms would also be beneficial. The right person must be eligible for UK security clearance and meet nationality requirements due to programme sensitivity. This is a strong opportunity for a 4D planner at any level looking to work on high-profile infrastructure programmes while developing their experience with digital planning tools within a consultancy environment that continues to grow.
