About Us
Diamond Light Source is the UKs national synchrotron; a huge scientific facility designed to produce very intense beams of X-rays, infrared and ultraviolet light. Our scientists use the light to study a vast range of subject matter, from new medicines and treatments for disease to innovative engineering and cutting-edge technology.
At Diamond we are currently undertaking a major upgrade of the facility, known as Diamond-II. Diamond-II will combine a new machine and new beamlines with a comprehensive series of upgrades to optics, detectors, sample environments, sample delivery capabilities and computing, which will ultimately generate an even more brilliant light source at a higher energy.
About the Role
We now have an opportunity for a Mechanical Technician or Senior Mechanical Technician to join our team.
As a Mechanical Technician, you will play a key role in the hands-on mechanical assembly, alignment, and installation of high-precision components and systems. Working within a multidisciplinary team, youll help deliver the next generation of synchrotron science infrastructure.
Key Responsibilities:
Assemble and install mechanical systems including vacuum chambers, magnets, supports, shielding, water and air systems.
Interpret engineering drawings and specifications to ensure accurate assembly.
Perform precision alignment and mechanical testing of installed systems to within 10s of microns.
Collaborate with engineers, scientists, and other technicians to meet project milestones.
Maintain high standards of safety, cleanliness, and documentation.
Act as competent person for lifting operations when trained and registered.
Drive Tug and Trailer, and Forklift Truck when trained and registered.
As a Senior Mechanical Technician you will:
