Thermal Design Engineer - Kaiku HR Oy - Jyväskylä, Finland

On behalf of our technology industry customer in Jyväskylä we now look for a THERMAL DESIGN ENGINEER to strengthen the in-house equipment design team. You will operate at the intersection of thermal engineering, simulation, and product development, focusing on high-performance heat transfer solutions in demanding industrial applications. Your responsibilities will include: Drive continuous improvement across thermal designs, materials, and engineering methods from concept development to validated industrial solutions. Apply advanced heat and mass transfer principles. Perform simulation-driven engineering and optimization. Design and develop heat exchangers and thermal management systems. Lead numerical modeling and validation workflows. Contribute to geometrical and functional innovation. Translate complex simulations into actionable engineering decisions and customer value. Maintain high-quality technical documentation and communicate findings clearly to both technical and non-technical stakeholders. In close team interaction you will grow into a thermal process specialist building on the technical insights derived from every project. Initial external consultant assignment is until further notice but holds the option of permanent employment with the end-customer. The assignment is also suitable for freelance entrepreneurs part of our supplier network. As the thermal design engineer we look for you need to have genuine interest in thermal design and optimisation. We expect you to be professional and self-driven sharing our passion for technology, engineering and the commitment to move our customers' performance forward.
