This is a newly established position offering a unique opportunity to take ownership of CFD simulation and thermal design activities while contributing to the mechanical development of our products. You will work closely with specialists within mechanics, electronics, power electronics, software and project management to ensure that thermal and mechanical solutions meet performance, quality and cost targets.

The role combines advanced simulation work with hands-on engineering, making it ideal for someone who enjoys both analytical problem-solving and practical product development.

Your responsibilities

• Design and optimise air and liquid cooling solutions for components and systems.
• Set up, execute and analyse CFD simulations.
• Translate simulation results into clear and actionable design recommendations.
• Validate simulation models through testing and measurements.
• Support development teams with thermal and cooling expertise throughout the product lifecycle.
• Participate in mechanical design, development and review activities.
• Develop technical reports and share findings across engineering teams.
• Contribute to the development of new methods, technologies and simulation capabilities.
• Participate in technology and product development projects.

Your profile

You are curious by nature and enjoy collaborating with colleagues from different technical disciplines. You can communicate complex technical findings in a clear and practical manner and thrive in an environment where innovation and continuous improvement are part of everyday work.

Furthermore, you:

• Hold a B.Sc. or M.Sc. in Mechanical Engineering or a related field.
• Have a strong understanding of heat transfer, fluid mechanics and thermal management.
• Have experience with CFD simulation and numerical analysis tools.
• Have experience translating simulation results into product improvements and design decisions.
• Enjoy combining simulation work with mechanical product development.
• Communicate fluently in English, both written and spoken.

Why join DEIF?

At DEIF A/S, you’ll be part of a family-owned company with strong values and a culture built on trust, openness, and collaboration.
