Software Development Engineer (Simulation)

This role focuses on the development of aircraft models using MATLAB/Simulink, supporting flight simulation, system validation, and certification activities. You will play a key role in ensuring that models accurately represent aircraft behaviour and are used to support design decisions, verification strategies, and system validation across the programme lifecycle. This is a unique opportunity to contribute to cutting-edge aerospace innovation while working at the intersection of software engineering, systems modelling, and real-world test correlation. This role is Hybrid working in Bristol. Responsibilities: Within this role, you will be required to :- * Develop and maintain aircraft and system models using MATLAB/Simulink to support simulation and analysis activities. * Support Flight Simulation Training Device (FSTD) environments, ensuring models meet fidelity and certification expectations. * Contribute to verification and validation activities at aircraft level, using modelling and simulation techniques. * Develop and integrate models into simulation frameworks and toolchains, supporting cross-disciplinary use

• Implement and maintain CI/CD pipelines for model development, testing, and deployment
• Perform data processing and analysis, including comparison of results from simulations, ground tests, and flight tests

Develop automation tools and scripts to streamline analysis, comparison, and reporting workflows

• Correlate simulation results with real-world test data, identifying discrepancies and improving model fidelity
• Collaborate with systems, safety, and test engineers to ensure models reflect system behaviour and requirements
• Support test campaigns, including preparation, analysis, and model validation using collected data
• Produce high-quality technical documentation, including models, assumptions, validation results, and reports, As a Disability Confident Committed Employer we have committed to:

• Ensure our recruitment process is inclusive and accessible
• Communicating and promoting vacancies
• Offering an interview to disabled people who meet the minimum criteria for the job
• Anticipating and providing reasonable adjustments as required
• Supporting any existing employee who acquires a disability or long term health condition, enabling them to stay in work at least one activity that will make a difference for disabled people

Do you have experience in System architecture?, Do you have a Master's degree?, * Bachelor's or Master's degree in Aerospace Engineering, Mechanical Engineering, or related field.

• Chartered engineer or working towards chartered status within a recognised and relevant professional body.
• Applications are invited from candidates who may hold HNC/HND in a relevant engineering discipline in concert with significant and demonstrable subject matter expertise in the system domain

Essential skills:

• Strong experience in MATLAB/Simulink model development
