Introduction
Saab UK is part of Scandinavia’s largest defence company, bringing together the best of Swedish and British innovation. Saab offers world-leading solutions and services in defence, aviation, space, and civil security to keep people and society safe. Our UK presence has been growing at pace, meaning we can offer a wide range of opportunities for personal fulfilment and career growth. We currently employ over 600 people across eight sites in the UK, and our specialisations include software engineering, underwater robotics, radars, AI, and armed forces training.
What You Will Be Part Of
Saab is a leading defence and security company with an enduring purpose, to help nations keep their people and society safe.
Empowered by its 28,000 talented people, Saab constantly pushes the boundaries of technology to create a safer and more sustainable world.
Saab designs, manufactures and maintains advanced systems in aeronautics, weapons, command and control, sensors and underwater systems.
Saab is headquartered in Sweden. It has major operations all over the world and is part of the domestic defence capability of several nations.
The Role:
This role is part of our Sensor Systems Radar Business in Fareham.
At Saab, we are constantly looking ahead and pushing boundaries on what’s considered technically possible. Saab is expanding in the UK and we are now seeking talented and highly motivated engineers to support our radar and sensors growth activities at our Fareham offices.
We are recruiting for a Senior Systems Engineer specialising in Positioning, Navigation, and Timing (PNT) and Distributed Sensing.
Key Responsibilities:
As a Senior System Engineer, you will be responsible for enhancing our current products, developing improvements and investigating new areas for product growth, as well as supporting the Engineering Team with various Systems Engineering-focussed activities.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- System Architecture & Design. Lead the architectural design of PNT solutions, integrating Global Navigation Satellite System (GNSS), Inertial Navigation Systems, and alternative PNT (e.g., vision-based, RF-based, or celestial navigation). Architect distributed sensing networks, defining how data is collected, synchronized, and fused across multiple remote nodes to create a unified operational picture. Define system-level requirements, interface control documents, and performance specifications for timing accuracy and positioning precision. Perform trade studies to optimise the balance between size, weight, power, and cost and system performance.
- PNT & Synchronization Expertise. Implement and optimise high-precision timing distribution protocols (e.g., PTP/IEEE 1588, NTP, or White Rabbit). Develop strategies for PNT resilience, including mitigation of jamming, spoofing, and GNSS-denied environment operations. Lead the selection and integration of atomic clocks, quantum oscillators, and high-grade IMUs.
- Distributed Sensing & Data Fusion. Design algorithms and architectures for distributed beamforming, phased arrays, or coordinated sensor fusion. Manage the challenges of network latency, jitter and asynchronous data arrival in distributed sensing environments. Collaborate with software teams to implement edge-processing capabilities to reduce data backhaul from sensing nodes.
- Integration, Test & Evaluation. Develop comprehensive verification and validation (V&V) plans to prove timing and positioning accuracy. Design and execute complex test campaigns using hardware-in-the-loop and software-in-the-loop simulations. Lead the analysis of telemetry and test data to identify systemic errors and drive corrective design changes.
- Leadership & Mentorship. Serve as the Subject Matter Expert for PNT and Distributed Sensing across cross-functional teams (Radio Frequency, Software, Mechanical). Mentor junior engineers in systems engineering best practices and specialized domain knowledge. Present technical roadmaps and progress reports to senior leadership and external.

- Proficiency with MATLAB/ Simulink for modelling and simulation.
- Experience with Model-Based Systems Engineering tools and requirements management tools.
- Familiar with the principles of ISO 15288:2023.
- During your employment you will handle tasks and materials that are classified as military secret and therefore you must have a UK or Swedish citizenship.
Desirable
- RF Knowledge: Strong understanding of RF front-end design, antenna theory and signal propagation.
- Programming. Proficiency in C++, Python, or Rust for prototyping algorithms.
- Security. Experience with encrypted PNT signals or secure timing distribution.
By submitting an application to Saab UK you consent to undertaking workforce screening activities that may include but are not limited to: Baseline Personnel Security checks, National Security Vetting, reference checks, verification of working rights and in all circumstances preferred candidates will be placed through a security interview.
