* Perform engineering calculations, thermodynamic analysis, and mathematical modelling to predict system performance.
* Produce and review refrigeration system specifications and technical documentation.
* Work closely with suppliers and manufacturing teams to ensure designs are practical, cost‑effective, and manufacturable.
* Plan, conduct, and analyse refrigeration system testing and validation activities.
* Identify opportunities for product improvements, cost reductions, and performance enhancements.
* Support root cause investigations relating to quality issues and customer feedback.
* Maintain documentation in line with ISO 9001 and ISO 13485 quality standards.
* Research emerging technologies and contribute to future product development strategies.
About You
* A degree in Mechanical Engineering or a related engineering discipline.
* Strong knowledge of thermodynamics and heat transfer principles.
* Experience designing or developing refrigeration systems or thermal management products.
* Experience supporting new product development projects.
* Knowledge of structured product development or phase‑gate processes.
* Understanding of Design for Manufacture (DFM), FMEA, and ISO 9001 design controls.
* Excellent analytical and problem‑solving skills with a practical, hands‑on approach.
Desirable Experience
* MSc or PhD in Heat Transfer, Thermodynamics, or a related field.
* Experience with RefProp, Flownex, SolidWorks, or similar engineering software.
* Knowledge of F‑Gas regulations and hydrocarbon refrigerants.
* Experience working within Agile development environments.
Benefits
* Salary up to £50,000 with annual salary reviews.
* Flexible working hours (Monday to Friday).
* 25 days holiday plus bank holidays.
