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. ## Description This role is part of our Sensor Systems Radar Business in Fareham., 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., 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. * 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. ## Related Videos - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Dirty Tests And How To Clean Them](https://www.wearedevelopers.com/videos/515-dirty-tests-and-how-to-clean-them) - [Robots are coming into the wild!
