Graduate Mechanical Engineer – Fluids & Thermodynamics

Hands-on mechanical engineering role focused on designing, testing, and developing complex products from concept to manufacture, using physics-based analysis (fluid mechanics, thermodynamics, heat transfer) across industries like industrial systems, energy, consumer devices, and defence, often involving prototyping, modelling, and client-facing problem solving.

Introduction 

Are you a curious and creatively minded mechanical engineer looking for exciting and fulfilling experiences?  Do you have a passion for understanding technology and a methodical approach to solving tough problems? Would you like to work on a wide selection of products for clients in the Industrial, Consumer, Energy and Defence industries? 

We are hiring a mechanical engineer interested in analytical sub-disciplines (e.g. fluid mechanics, thermodynamics and heat transfer). You can expect this role to include a mixture of desk-based and practical tasks. 

Successful candidates can join us between May – October 2026.     

There is no deadline for this role, as we recruit on a rolling basis. Once the position is filled, we will close the advert. We encourage you to apply as soon as possible.  

The role  

The Mechanics and Design Department undertakes the development of innovative devices and equipment from concept to manufacture whilst addressing considerable technical and design problems. 

We are looking for someone passionate about understanding technology from first principles.  We combine user centred design, innovative mechanical engineering, a rigorous systems engineering approach to problem solving and a broad base of industry experience to form a powerful development team.

Our work ranges from undertaking complete product developments from concept to market, to providing consulting services for our clients on their technology, strategy or development processes. One of our key capabilities is in fluid dispense technology development e.g. aerosols, foams, microfluidics and heating/cooling systems. 

What you’ll be doing  

This is an excellent opportunity for a mechanical engineer with the ambition and intent to achieve excellent results within highly demanding industries under commercial and time constraints. You will be using your technical skills to contribute to product development projects with support and guidance from seniors; from initial idea generation through to the delivery and manufacturing support for market ready products.

This may include: 

• Carrying out research into cutting edge technologies and markets 

• Taking part in concept generation and problem-solving workshops 

• Evaluating ideas using evidence from modelling or experimentally obtained evidence 

• Preparation of detailed designs, from system to component level 

• Manufacturing of parts and assemblies, hands-on or by liaising with suppliers 

• Testing of designs to ensure they meet the client’s and end customers’ needs 

What you can bring

A successful mechanical engineer in the Mechanics and Design Department will have a strong ability to: 

• Use maths and physics to solve complex engineering problems, especially those involving fluid mechanics, heat transfer and thermodynamics 

• Communicate with peers and clients to understand their problems and present your solutions 

• Design elegant solutions to client’s problems 

• Obtain and analyse simulated/empirical test data to gain insights into design performance 

• Demonstrate an excellent academic record, studying for or having completed a relevant engineering degree
