Location: Hertfordshire (hybrid/flexible considered)
We’re partnering with a UK-based defence and aerospace power-electronics specialist that designs and manufactures mission-critical power systems used in some of the most demanding environments worldwide. They’re now looking to add a Mechanical Design Engineer to their engineering team — someone who enjoys designing ruggedised, high-reliability mechanical solutions and wants to see their work deployed in real defence and aerospace programmes.
What you’ll be doing:
- Designing rugged enclosures, housings, and mechanical assemblies for power electronics used in harsh environments
- Producing 3D models and detailed manufacturing drawings (SolidWorks) from concept through to release
- Engineering designs to meet shock, vibration, ingress protection, and environmental standards (MIL-STD / DEF-STAN / IP)
- Supporting thermal management and structural integrity, ensuring designs perform under extreme operating conditions
- Working hands-on with prototypes, building support, and environmental/EMC testing
- Creating clear technical documentation, BOMs, and compliance evidence for defence programmes
- Collaborating closely with electrical engineers, project managers, and suppliers to ensure designs are manufacturable, robust, and cost-effective
What we’re looking for:
- Degree-qualified in Mechanical Engineering (or similar)
- 3+ years’ experience in mechanical design for defence, aerospace, or ruggedised electronics
- Strong CAD capability (SolidWorks preferred), with a solid understanding of GD&T and material selection
- Experience designing for harsh environments, including vibration, shock, and thermal constraints
- Familiarity with MIL-STD-810, DEF-STAN, and structured quality systems (ISO 9001)
- Detail-oriented engineer who’s comfortable working to tight technical and regulatory requirements
Nice to have (but not essential):
- Exposure to electromechanical integration
- Understanding of DFM/DFA for low-volume, high-reliability production
- Experience working with defence documentation and procurement standards
What’s on offer:
- Competitive salary aligned with experience
- Pension scheme
- Flexible working options
- Ongoing training and professional development
- The chance to work on long-life defence and aerospace programmes with real-world impact
