What are the responsibilities and job description for the Mechanical Design Engineer II position at ExtensisHR?
Cambridge Design Partnership is looking for a Mechanical Design Engineer II to join our growing US team.
This role is suited to an early-career engineer with around 2-5 years of relevant experience who is ready to take ownership of defined engineering workstreams, contribute to multidisciplinary product development projects, and continue building the skills needed to become a rounded product development consultant.
You will work across sectors including medtech, life sciences, drug delivery and consumer. Projects may span early concept generation, prototyping, engineering development, testing, design for manufacture, and transfer into production.
We are looking for someone who can combine strong mechanical design fundamentals with practical hands-on engineering, clear communication, and the ability to work well with clients and multidisciplinary teams. Regular on-site presence is required, with a minimum expectation of three days per week in the office.
