Help shape the future of high-performance cooling technology
Are you excited by solving complex thermal challenges where performance, reliability and innovation genuinely matter?
We’re looking for a Thermo-Fluids / Thermal Engineer to join a growing engineering team developing next-generation liquid cooling solutions across a diverse portfolio of high-performance technologies.
Our technology supports applications operating in demanding real-world conditions.
You'll play a key role in designing and optimising thermal solutions that enable mission-critical technologies to operate reliably in environments where performance cannot fail.
Working within a highly collaborative engineering team, you’ll contribute across the full product lifecycle — from concept development and simulation through testing, validation and deployment.
The opportunityAs Thermal Engineer, you’ll help shape innovative cooling technologies by:
You'll gain exposure to:
✔ Advanced liquid cooling technologies
✔ High-density computing and critical infrastructure applications
✔ Innovative power and server technologies
✔ Global projects and customer interaction
✔ A highly collaborative engineering environment where ideas influence products
If you’re passionate about solving complex thermal problems and want to develop technologies that power the next generation of critical systems, we'd love to hear from you.
