Company description: Ericsson AB Job description: Join our Team About this opportunity: Do you want to shape the future of thermal management for next-generation telecommunications products? Are you passionate about solving complex thermal challenges and translating advanced cooling concepts into industrial solutions? This is your chance. We are now looking for a Thermal Design Engineer to join Ericsson's global Thermal Design organization. You will become part of a highly skilled team of thermal specialists supporting product development across Ericsson's product portfolio. Working closely with multidisciplinary teams in Sweden and our global R&D centers, you will play a key role in advancing innovative thermal-management technologies for next-generation telecommunications products. What you will do: Own and drive thermal design activities across the product development lifecycle, delivering advanced thermal-management solutions for electronic products and systems from concept evaluation through product release. Perform CFD simulations and other relevant modeling approaches to support product design and technology development. Plan, execute, and interpret thermal measurements and validation activities to ensure design robustness and performance. Collaborate closely with thermal designers, product development teams, and technology experts across Ericsson's global R&D organization to develop and optimize thermal solutions. Analyze and present numerical and experimental results to technical stakeholders and management. Support root-cause investigations, task forces, and customer-related thermal issues when required. Drive continuous improvement of thermal tools, methodologies, and design processes. The skills you bring: B.Sc or M.Sc´s degree in Mechanical Engineering, Thermal Engineering, Engineering Physics, Applied Mathematics, Computational Science, Aerospace Engineering, or a related field. Strong understanding of heat transfer, fluid dynamics, thermodynamics, and numerical methods. Experience with CFD simulations using tools such as Celsius EC, FloTHERM, Fluent, Discovery, Icepak, Star-CCM+, COMSOL, or equivalent. Experience with computational design methodologies, including design exploration, parametric optimization, topology optimization, and data-driven engineering approaches. Experience leveraging scripting, automation, and AI-assisted engineering workflows using Python, MATLAB, or similar technologies is considered an advantage. Strong analytical and problem-solving skills with the ability to translate simulation results into design improvements. Ability to work independently while effectively collaborating across disciplines, organizations, and cultures. Excellent communication and presentation skills in English, both written and spoken. Strong curiosity, innovation mindset, and willingness to challenge conventional engineering approaches.
