Job Description

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
