Contract Test & Development Engineer - Mechanical Engineering

Inside IR35 - 12 Month Contract + Ext
South Wales - On-site - Rate dependent on experience

Yolk Recruitment is exclusively partnered with a global engineering business's with an established customer base of major blue-chip manufacturers, and a track record of offering long-term contract opportunities at their well resourced UK centre for engineering excellence.

This is a 12 month contract with a further 12 months very realistic, on site, supporting a live long-term programme, with further work behind it. You'll be working to validate and verify mechanical components and assemblies, progressing designs through development stages with a mix of theoretical analysis and hands on strip down of components, determining and coordinating test activities, reviewing results, investigating failures and feeding finds back into the wider engineering team.

You'll need a mechanical engineering or related degree with strong theoretical knowledge, will be able to read engineering drawings including GD&T and will be used to creating detailed engineering reports. Hands on at times, you'll be solving real world engineering problems, investigating failures and contributing to solutions.

This is what you'll be doing

Support the development and validation of mechanical components and assemblies
Interpret engineering drawings, including GD&T, and assess fit, function and tolerance stack-up
Define test requirements and work with the test team to make sure validation activity is carried out correctly
Review test data and engineering reports to assess whether components are performing as intended
Investigate failures, wear and deterioration in tested parts and assemblies
Strip down components and identify likely failure points before further specialist analysis where needed
Feed findings back into engineering decisions around dimensions, materials and product performance
Produce clear technical reports to support internal engineering activity and, where required, customer reporting
Work closely with design, test and materials teams throughout the development cycleAnd this is what you'll need

Degree qualified in Mechanical Engineering or a related discipline
Previous experience in a development, validation, test or product-focused mechanical engineering role
Strong ability to read and interpret engineering drawings
Good understanding of GD&T and tolerance stack-up
Comfortable working with physical components, not just drawings and data
Experience investigating engineering problems and understanding why a part has failed or underperformed
Strong mechanical fundamentals, including material considerations, forces and component behaviourAre you up to the challenge?
