Principal Signal Processing Engineer Can be based in either; Cowes (Isle of Wight), Portsmouth or Chelmsford Hybrid – typically 2-3 days per week in the office £60,000–£70,000 depending on experience Do you love diving deep into problems and crafting elegant, efficient signal processing algorithms? This is a hands-on, technical role where your work will feed directly into mission-critical radar systems used in national defence. You’ll be part of a close-knit, highly skilled engineering team working across the full development lifecycle. From building MATLAB models to defining and validating algorithms, you’ll take real ownership of the technical solutions you design—without any line management or people oversight. Just uninterrupted problem-solving. What You’ll Be Doing * Designing and developing advanced signal processing algorithms for radar platforms * Using MATLAB to model, develop, test, and validate performance * Defining and managing system and sub-system requirements using IBM DOORS Next * Collaborating with design leads and fellow engineers to integrate your algorithms into wider radar systems * Applying Systems Engineering principles (ISO 15288) across the full lifecycle Who We’re Looking For * Someone with a background in Software Engineering, Physics, Computer Science, or similar * Strong experience in Signal Processing—industry ...
