Job Title: Performance Modelling Engineer
Location: East Midlands (Fully Onsite)
Employment Type: Permanent
Working Hours: 40 hours per week
Industry: Clean Energy / Propulsion / Power Systems
Overview
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 and 1D models within a model-based architecture, using tools such as MATLAB, Simulink and Simscape 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 0D/1D system-level performance models using MATLAB/Simulink/Simscape for early‑stage concept evaluation
* 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
Essential:
* BEng, BSc or equivalent in engineering, physics or a related discipline
* Strong experience with MATLAB, Simulink and Simscape for model‑based system architecture
* Proven capability in 0D/1D modelling of complex energy, thermal, or fluid systems
* Sound understanding of thermodynamics, fluid dynamics, or energy systems
* Ability to build pragmatic, simplified models based on first principles
Desirable:
* Chartered Engineer status or working towards chartership
* Sector experience in aerospace, automotive, or energy industries
* Familiarity with model automation, toolchain development, or simulation roadmapping
