Mechanical Design Engineer

We are seeking an experienced Mechanical Design Engineer to join our team working on advanced technology systems including high temperature super conducting magnets, cryogenic refrigeration, vacuum technology and pressure systems.

You’ll be working as part of a multidisciplinary team designing and delivering complex mechanical systems and assemblies that operate in demanding conditions, including:

High magnetic field environments

Cryogenic temperatures

Vacuum technology

High-energy and high-current applications

High precision temperature diagnostic instruments

Ionising radiation

Pressure systems

This role is best suited to engineers who have already worked in highly technical, physics-driven or extreme operating environments, where understanding system behaviour is critical from day one.

We are particularly interested in candidates with experience in industries such as:

Superconducting magnet systems or high-field applications

Cryogenic engineering (low-temperature systems, cryostats, thermal management)

Vacuum systems and pressure-controlled environments

Scientific research or instrumentation (particle accelerators, experimental physics equipment, advanced labs)

Aerospace and space systems (high-reliability, extreme environments)

Advanced energy systems, including: Nuclear fission or fusion energy, high-power electrical systems, turbomachinery or rotating equipment, electromagnetic or high-current systems where structural and thermal effects are critical

These environments develop engineers who understand challenges such as thermal contraction, electromagnetic loading, vacuum compatibility, and safety-critical design, which are essential in this role.

Degree (or equivalent experience) in Mechanical Engineering

Strong CAD and mechanical design experience

Background in complex, high-performance engineering systems as per the above description

Ability to work across multidisciplinary teams

Direct experience in one or more of the industries listed above

Understanding of:

Electromagnetic forces and their mechanical impact

Cryogenic materials and thermal behaviour

Vacuum design principles

Experience with safety-critical or highly regulated systems
