Mechanical Design Engineer

Mechanical Design Engineer Contract | Guildford | On-Site | 12 Months | Inside IR35

Our client, a leader in the aerospace sector, is seeking a highly motivated Mechanical Design Engineer to contribute to the development of current and future spacecraft missions. This is a fantastic opportunity to be involved in the full engineering lifecycle — from initial concept through to final integration — within an innovative and collaborative environment.

You’ll play a key role in the design and integration of spacecraft structures and sub-systems, working closely with cross-functional teams including project managers, systems engineers, manufacturing, and senior analysts.

Key Responsibilities:

• Design mechanical components and systems using 3D CAD (SolidWorks), ensuring compliance with customer and mission requirements.
• Produce detailed manufacturing drawings and support procurement, inspections, and manufacturing activities.
• Document and manage design changes through Engineering Change Notices (ECNs).
• Write technical assembly procedures and integration documentation.
• Support cleanroom-based integration of mechanical components and sub-assemblies.
• Maintain detailed build logs and create Bills of Materials (BoMs) using MRP systems.
• Collaborate with electrical engineers on the design of enclosures and PCB outlines, ensuring compatibility with electronic assemblies.
• Contribute to the mechanical design of systems such as propulsion, mechanisms, and optical instruments when required.

What We’re Looking For:

Essential:

• Strong experience in mechanical design, ideally within the aerospace, space, defence, or motorsport industries.
• Proficient in SolidWorks and competent with Microsoft Office tools.
• Knowledge of materials, surface treatments, and finishes for aerospace applications.
• Experience in hands-on build, integration, and testing of mechanical systems.
• Ability to write clear and accurate technical documentation.
• Strong attention to detail and the ability to work under pressure and to tight deadlines.
• Experience with drawing checking and release processes.
• Understanding of production and manufacturing methods.

Desirable:

• Familiarity with MRP systems.
• Experience in electrical harness integration.
• Understanding of spacecraft systems and the constraints of space environments.
