I am working with a global industry leading Mining and machinery company who are looking for a Senior Mechanical/Design Engineer in Peterborough, UK. We’re building a specialist engineering team to take ownership of the full diesel engine system—from air intake to exhaust. Each team member will focus on a specific component area such as pistons, turbochargers, injectors, or exhaust systems etc., while collaborating to deliver a fully integrated and high-performance engine. This is an exciting opportunity for experienced engineers who want to work hands-on with suppliers, define and review specifications, develop and test prototypes, and finalize designs using CAD tools. You’ll be responsible for ensuring your component meets performance, durability, and emissions standards, and you’ll play a key role in shaping the engine as a whole. What We’re Looking For: 10 years of experience in diesel engine development (off-highway or automotive). Specialization in one or more of the following: pistons, turbochargers, injectors, exhaust systems etc. Strong CAD skills and experience working with suppliers. Proven ability to take a component from concept to production. Excellent communication and negotiation skills. A proactive, flexible mindset – open to contract or permanent roles. If this is something that might interest you please apply!
