World Class Defence Organisation based in Stevenage and Bristol is currently looking to recruit a Systems Performance Modelling Engineer subcontractor on an initial 12 month contract. Your base site can be either Stevenage or Bristol, depending on your preference. The role can be worked on a 4 day week basis (Monday to Thursday) but due to the nature of the work, the position will need to be based onsite. This role would be suitable for a Simulation and Modelling Engineer (Matlab / Simulink) ideally from the defence or aerospace industry.Rate:£80.00 per hourLocation: Your base site can be either Stevenage or Bristol, depending on your preferenceHybrid / Remote working: The role will based onsite.

The model includes the seeker hardware, digital processing and target environment. The modelling team is responsible for developing the model, producing auto-code, generating seeker performance predictions and interfacing the seeker model into the missile dynamic reference model.Responsibilities (to include):Modelling in Matlab and Simulink using model-based design techniquesProducing parts of a complex Seeker model including modelling the target scenario, seeker hardware and processor algorithmsDevelop and implement algorithms within the modelProducing and verifying auto-code for the software algorithms from the modelCarrying out seeker performance assessmentProducing a simpler representation of the model for use in the missile modelUpgrading legacy Seeker models to newer MATLAB/Simulink VectorsDocumenting the model changes and creating test vectorsDue to the sensitive nature of the work it is predominantly done onsite but there is some flexibility depending on project.Skillset / experience required:Tools:SimulinkMatlabSkills:Modelling for auto-codingAssessing suitability of algorithms in the modelAptitude for converting an algorithm into a Simulink model (desirable)Familiarity with Radar and Control Systems (desirable)Familiarity with Digital Signal Processing (desirable)RF experience (desirable)Experience in C (not essential)Technical report writingModel delivery experienceJBRP1_UKTJ
