Mechanical Design Engineer

This is genuinely consequential engineering work that will have battlefield impact within 6 months of design.

Minerva Defence is one of the fastest-growing defence technology companies in Europe. We create the software, hardware and networking that make unmanned systems effective on the modern battlefield, all ideated, designed and manufactured end-to-end in the UK, and in active use today. We are deliberately low-profile: a team of around 60, small in headcount and outsized in effect. We look for people who are not just talented but genuinely committed to the work, the team, and the purpose behind it.

This is the kind of work you will be proud of. Mechanical design here carries real weight: you will own significant work packages, make decisions with full context, and contribute across a complex, multidisciplinary product. The gap between designing something and seeing it in production is weeks, not years.

• Design and develop mechanical components and assemblies across the full product lifecycle, from concept through production release
• Produce CAD models and engineering drawings to the required standard, applying appropriate tolerancing, material selection and DFM/DFA principles so designs can be manufactured, assembled and supported at scale
• Perform engineering analysis and calculations to support and validate design decisions
• Work directly with manufacturing, assembly and quality teams to resolve technical issues and support build activities
• Participate in design reviews, presenting work clearly and responding to technical feedback
• Manage engineering changes and maintain accurate configuration control in line with company processes
• Support prototyping, testing and design iteration as products develop
• Contribute to engineering standards and processes as the team scales
