Performance and Simulation Engineer

Portsmouth

Salary - £40,000 - £55,000

Full time - Permanent

Are you passionate about simulation, data-driven engineering, and making a tangible impact on sustainability within the marine sector?

A forward-thinking marine engineering company, pioneering clean technology and next- vessel design are seeking a Performance and Simulation Engineer to join their dynamic team. This is your opportunity to work on cutting-edge marine decarbonisation technologies, contributing to the optimisation of high-performance vessel systems in a fast-paced, innovation-led environment.

About the Role:

This role sits at the intersection of simulation, performance modelling, and engineering insight. You’ll play a key part in shaping how next- marine propulsion and hydrodynamic systems are designed, tested, and communicated—translating technical analysis into real-world impact.

Key Responsibilities:

Analyse and interpret simulation data from performance studies, routing models, and CFD outputs.

Develop tools in Python for performance modelling, data processing, and visualisation.

Automate visual outputs using libraries like Plotly, Matplotlib, and Seaborn.

Produce technical reports and tailored client presentations that clearly communicate complex data.

Lead the development of aerodynamic and hydrodynamic performance models.

Work closely with control systems, design, mechanical, and commercial teams to drive multidisciplinary projects.

Maintain and improve a library of visual templates and workflows for reporting.

Explore integration of AI and machine learning into simulation, routing, and optimisation tools.

Stay informed on the latest developments in data science, simulation, and maritime sustainability.

What We’re Looking For:

A strong academic background in Engineering or a related STEM field.

Proficiency in Python and experience applying data analysis or simulation tools.

Strong communication skills, both technical and client-facing.

Highly organised with excellent attention to detail.

Comfortable working in a collaborative team environment and taking ownership of tasks.

Confident using PowerPoint and presenting findings to stakeholders.

Desirable Skills:

Experience managing multiple projects within a multidisciplinary team.

Object-oriented programming experience.

Familiarity with AI or machine learning for optimisation or forecasting.

Background in aerodynamic or hydrodynamic performance engineering and/or CFD.

Opportunities for Growth:

You’ll have the opportunity to become a well-rounded performance engineer, gaining exposure to cutting-edge tools, machine learning applications, and sustainable marine technologies. As you grow in the role, you’ll take on more ownership, contribute to client-facing projects, and be part of a team reshaping the maritime landscape.

What’s in It for You:

Join a close-knit, high-impact team at the forefront of marine innovation.

Work on meaningful sustainability challenges in an applied engineering context.

Continuous professional development opportunities in a fast-moving environment.

Competitive salary and benefits package including:

25 days holiday

Company pension

Private medical insurance

Life assurance

Electric car salary sacrifice scheme

Cycle to work scheme

Regular social events
