About the role:
This is a unique opportunity to join JCB Power Systems at our cutting-edge engineering centre in Foston, Derbyshire, where innovation meets impact. As a Principal Design Engineer, you'll play a pivotal role in shaping the future of engine technology-leading design projects that span from concept to production, including next-generation hydrogen and combustion platforms. You'll be part of a passionate team driving forward our mission to build a cleaner, more efficient future, with the freedom to influence, mentor, and make a real difference in a fast-paced, forward-thinking environment.
What does this role involve day to day?

• Lead the day-to-day design engineering activities of a team, across full engine NPI programs, sprint programs, and current product support
• Collaborate with internal and external stakeholders, manage team workload, and integrate with wider project teams to meet deadlines
• Provide technical guidance, mentorship, and leadership while contributing to process development and team direction

This will be suited to you if...

• You have relevant experience and can work autonomously, applying engineering first principles to solve complex problems
• You hold a degree in mechanical engineering or a related discipline, with strong CAD expertise (preferably Siemens NX)
• You have experience designing medium-duty diesel engines and components, and are proficient in calculations for camshaft design, bearing sizing, bolted joints, gasket loads, belt drive systems, and tolerance stacks
• You're confident with GD&T, technical documentation, and working with FEA, CFD, and combustion simulation tools
• You have excellent people and communication skills, and experience leading engineering teams

What happens next?
Ordinarily, our Resourcing Team reviews and shortlists CVs. If shortlisted, you'll speak to one of our Recruiters to discuss the role further. Our interview process usually consists of an initial Teams interview followed by an in-person interview. We'll keep in touch throughout the process, but if you have any questions, please get in touch at recruitment@jcb.com

What's in it for you?
This is your chance to join a company that values expertise not only in rewards but also in real employee care. At JCB you don't just get a competitive salary, 33 days' holiday and access to our company pension-you can also use our onsite gym, in-house doctor, dentist and visiting optician. We have an ULEV car scheme available for our employees too. Then there's the JCB Rewards Hub, which gives you discounts with high street retailers. Feel like biking to work? There's our Cycle to Work Scheme.
