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.

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.

The successful candidate is expected to fulfil the requirements of a Saab Specialist, and act as a technical leader to: drive development, lead innovation and anticipate future trends, identify opportunities, mitigate risks, and advocate change to maintain competitiveness. Also lead competence development, and formulate and maintain Specialist Work Programmes.

• 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…
