Mechanical Design Engineer - Mid-Level Talent Pool

for our Careers & Life at JCB pages

As a Mechanical Design Engineer at JCB, you'll play a key role in developing the next generation of world-class construction and agricultural equipment. Working on real products that operate in some of the toughest environments on earth, you'll own the design and delivery of critical systems from concept through to production, shaping the future of our machines and technology.

This advert supports multiple upcoming opportunities across JCB's engineering divisions. Successful candidates will be considered for suitable Mechanical Design Engineer positions aligned to their skills and experience.

Projects may include Loadall telescopic handlers, excavators, wheel loaders, Fastrac tractors, defence products, power systems, and future electrified machine platforms.

Depending on the programme, you may also contribute to future technologies including electric powertrains, alternative fuels, autonomous systems, connected machines, and advanced operator environments.
