We are currently seeking an experienced Thermal Design Engineer to support the design and development of ultra-low temperature refrigeration systems. This is an exciting opportunity to join a forward-thinking engineering team working on cutting-edge technology within a regulated product environment.

You will play a key role in the full product development lifecycle, from concept through to validation and manufacturing support, using an agile approach to deliver high-performance and cost-effective refrigeration solutions.

Key Responsibilities

As a Thermal Design Engineer, your responsibilities will include:

• Designing and developing ultra-low temperature refrigeration systems to meet customer and product requirements.
• Applying numeric calculation and modelling methods to validate design performance while minimising reliance on prototypes and experimental testing.
• Developing and reviewing system and component specifications for both prototype and production units.
• Ensuring specifications are feasible and cost-effective by working closely with suppliers and manufacturing teams.
• Producing and maintaining technical documentation to meet regulatory and organisational standards (including ISO 9001 and ISO 13485).
• Supporting refrigeration testing activities, ensuring testing plans meet required quality standards.
• Guiding test engineers through planning and execution, analysing results, and driving product improvements.
• Contributing to the refrigeration technology roadmap by researching and developing innovative technologies and solutions.
• Supporting field quality issues by providing technical expertise to identify root causes and recommend short- and long-term corrective actions.
• Providing engineering support to manufacturing processes to ensure product quality and safety standards are met.
