Job description

We are looking for a Senior Thermal Systems Design Engineer to join the team to deliver the design of thermal systems for new products, including motors, electronic units and whole electric propulsion units (EPU), based on the combined evaluation of thermodynamics, fluid mechanics, and heat transfer.

Key Responsibilities

• Own the design of thermal systems for Evolito's product range
• Validate and assess results against real-world constraints and draw sound conclusions
• Guide junior CAE Engineers, Designers and Systems Engineers during the design phase for optimised solutions based on thermal and pressure drop results
• Analysis and optimisation of complete/sealed liquid cooling systems including major loss contributors and heat dissipators
• Specification of pumps for coolant flows and required airflow to support liquid/air heat exchangers
• Specification of heat exchangers based on cooling requirements and fluid flow rates
• Liaise with key suppliers and customers on design and development issues, resolve to the optimal solution and understand the compromises
• Understand design for assembly and constraints for high volume manufacture
• Write specifications and reports as required through the product lifecycle, utilising a structured approach to problem-solving techniques

Skills and Experience Required

• Degree or equivalent in a degree related to thermal engineering
• Strong mechanical or electrical engineering background, but more importantly, be able to apply knowledge to real-world situations
• Practical knowledge in the design, use, and application of electric machines or rotational/complex components
• Experience with finite element analysis methods e.g. CFD and programs e.g. ANSYS Fluent
• Self-sufficient and able to work with minimal managerial input
• Confident dealing with customers and suppliers, able to detail requirements and understand issues
• Strong communication skills (both written and verbal), good collaboration skills, and the ability to work effectively across teams
