£Competitive

We're seeking a Senior Mechanical Design Engineer to support the development of advanced microturbine propulsion systems. This is a hands-on role focused on the design, development, testing, and continuous improvement of high-performance rotating machinery.

You'll take ownership of mechanical components and assemblies, working closely with manufacturing and test teams to deliver robust, manufacturable designs. As a senior member of the team, you'll also provide technical guidance and mentoring to junior engineers.

Key Responsibilities

* Design and develop components and assemblies using SolidWorks.
* Produce manufacturing, assembly, and inspection drawings, including GD&T.
* Lead mechanical packaging and layout activities.
* Drive **Design for Manufacture and Assembly (DFMA)**, particularly for rotating components.
* Support prototype builds, testing, root-cause investigations, and design iteration.
* Conduct design reviews and contribute to engineering best practice.
* Mentor and support less experienced engineers.

About You

* Degree qualified in Mechanical Engineering or similar.
* Strong mechanical design experience with complex products and assemblies.
* Highly proficient in SolidWorks (other cad packages considered)
* Strong understanding of GD&T, tolerance analysis, and engineering documentation.
* Experience applying DFMA principles to real-world products.
* Comfortable working hands-on with prototypes and testing activities.
* A collaborative problem solver with the confidence to lead technical workstreams.

Relevant Backgrounds

We're particularly interested in engineers with experience designing:

* High-speed motor-generator units (MGUs)
* Electric motors and e-machines
* Turbochargers and e-compressors
* Precision rotating equipment
* High-performance mechanical products
* Jet Engine Turbine related technology

Experience with shafts, bearings, rotors, housings, balancing, precision assemblies, and reliability-focused design would be highly advantageous.

This is an excellent opportunity to join a fast-moving engineering team developing next-generation propulsion technology, where you'll have significant influence on both product development and the growth of the engineering team.
