Senior Performance Engineer
Location: Loughborough, England, United Kingdom
Employment Type: Permanent, Full-time
Working Hours: 40 hours per week
Industry: Clean Energy / Propulsion / Power Systems
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.
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.
Key Responsibilities
* 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
Skills & Experience
* 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
