Mechanical Engineer - Propulsion Systems

Mechanical Engineer – Propulsion Systems

Contract | 6 months initially | Outside IR35

Location: Wiltshire initially, relocating to northeast Swindon in mid-January

Working pattern: Typically 4 days on-site per week

Start date: ASAP, ideally early November 2026

About the Opportunity

An opportunity has arisen for a Mechanical Engineer to support the design and development of a 350 N microjet turbine engine for uncrewed aerial systems (UAS/UAVs).

Working within a small, fast-paced engineering team, you will support the mechanical design and CAD work required to develop a compact propulsion system, working closely with senior engineers and the CTO.

This is a hands-on contract for an engineer who enjoys solving practical design challenges and helping turn engineering concepts into physical hardware.

The Role

You will support the mechanical design and development of a microjet turbine engine, contributing to CAD models, engineering drawings and the development of prototype components.

Responsibilities are expected to include:

• Producing and developing 3D CAD models and engineering drawings using SolidWorks.
• Supporting mechanical design activities for the engine and associated propulsion systems.
• Developing component designs and assemblies to meet engineering requirements.
• Supporting design iterations and resolving mechanical engineering challenges.
• Working with senior propulsion engineers to translate concepts into manufacturable hardware.
• Supporting prototype development and incorporating design feedback.
• Collaborating with the wider engineering team on component integration and design improvements.
• Considering manufacturing methods, component interfaces and practical assembly requirements.

Essential Experience

• A relevant Mechanical Engineering degree or equivalent engineering background.
• Strong mechanical design and 3D CAD capability, ideally using SolidWorks.
• Experience producing engineering models, drawings and assemblies.
• Practical understanding of mechanical engineering and component design.
• Ability to work independently, solve problems and contribute within a small engineering team.
• Availability for an early November start and the required on-site working pattern.

Why Consider This Contract?

• Work on the mechanical design of a developing microjet propulsion system.
• Work closely with senior engineering leadership in a small team.
• Contribute directly to prototype development and practical engineering challenges.
• Gain exposure to sovereign UK propulsion capability for uncrewed applications.
• Initial six-month contract with potential for extension or permanent employment.
