Design Engineer Role
In Semiconductor Wafer
Bonder Systems

STRICTLY NO AGENCIES!

About the Role

We are seeking a Design Engineer to strengthen our mechanical design capability and support both new product development and continuous improvement of existing platforms.

You will be working closely with the Design, Production and testing teams and be responsible for mechanical & electro-mechanical designs while contributing to continuous improvement of existing platforms and components.  This role is hands-on and practical, involving precision mechanical design, vacuum-compatible systems, motion and drive mechanisms.  After familiarisation and training you will be given responsibility for subsystems and complete design packages.  You would be working in our office based at Library Avenue, on Harwell Campus but may occasionally be required to travel in the UK or abroad to support customers. The hours of work are 8.30am to 5pm with 45 minutes for lunch.
