Senior Performance Engineer

We’re seeking a Performance Modelling Engineer to take ownership of high-level system modelling at the concept stage for advanced power and propulsion systems. You’ll be responsible for developing 0D models to support early design decisions and trade-offs - including efficiency, mass, and power output., * Develop and manage system-level performance models for early-stage concepts

• Produce and maintain version-controlled performance decks aligned with design updates
• Analyse performance predictions and identify areas for system optimisation
• Inform system sizing and architecture decisions through modelling and trade studies
• Collaborate with engineering teams to create simplified models and support design reviews
• Provide data and insights to support both technical and commercial decision-making
• Work with customers to manage input data and communicate performance implications
• Generate pragmatic, first-principle models for early concept evaluation
• Contribute to the development of automated, robust simulation tools and modelling processes
• Support validation of performance models in collaboration with R&D, CAE, and Test teams
• Assist in developing system-level models (e.g. full-vehicle or aircraft applications)
• Document model results and prepare technical reports for specifications and forecasts

This is a fully onsite, hands-on technical role suited to someone who can work independently while engaging closely with multi-disciplinary teams. A background in thermodynamics, fluid systems, or power generation is ideal. Aerospace experience is welcome but not essential., * BEng/BSc or equivalent in engineering, physics or related discipline

• Strong experience in system-level modelling using tools such as MATLAB
• Sound understanding of thermodynamics, fluid dynamics or energy systems
• Ability to build pragmatic, simplified models based on first principles
• Chartered Engineer status or working towards chartership
• Sector experience in aerospace, automotive or energy industries
• Familiarity with model automation, toolchain development or simulation roadmapping
