Overview
Expleo is a trusted partner for end-to-end, integrated engineering, quality services and management consulting for digital transformation. We help businesses harness unrelenting technological change to successfully deliver innovations that will help them gain a competitive advantage and improve the everyday lives of people around the globe.
As part of our continued growth in flight controls, we are seeking a Software Development Engineer specialising in modelling, simulation, and verification & validation (V&V) to support the development of next-generation electric rotorcraft (eVTOL) platforms.
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
Qualifications
- 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
- Experience working in simulation environments, ideally including FSTD or high-fidelity simulators
- Understanding of aircraft systems and modelling principles
- Experience with verification and validation using models and simulation
- Strong capability in data analysis and processing, including working with multiple data sources
- Experience in automation and scripting (e.g. MATLAB scripting, Python or similar)
- Experience implementing or working with CI/CD pipelines for software or model development
- Strong problem-solving and analytical thinking capability
- Clear and concise technical documentation skills
Desired skills
Experience with flight simulation, pilot-in-the-loop simulation, or FSTD certification processes
Familiarity with aerospace system modelling (flight dynamics, controls, propulsion, or electrical systems)
Experience supporting ground and flight test correlation activities
Knowledge of EASA certification standards and model-based verification approaches
Familiarity with MBSE environments and integration of models within wider system architecture
Experience in Advanced Air Mobility (AAM), eVTOL, or emerging aviation platforms
Understanding of control systems, dynamics, or real-time simulation environments
