Test Design Engineer designing scalable test architectures for aerospace and defence systems. Leading technical direction and ensuring compliance with customer requirements and MOD standards
About the role
- Thermal & Mechanical Design Engineer developing cooling solutions for high-power accelerator cards. Collaborating with senior architects to design and validate mechanical structures in cutting-edge AI and HPC environments.
Responsibilities
- We are seeking a Thermal & Mechanical Design Engineer to support the development of next-generation accelerator boards used in data center servers for HPC and AI/ML workloads.
- You will work closely with our senior thermal/mechanical architect to design, analyze, and validate cooling solutions and mechanical structures for high-power PCIe and custom form-factor accelerator cards.
- Collaborate with the senior thermal/mechanical architect on thermal design of accelerator PCBs and assemblies, including: Heat sink and cold plate design, Air and liquid cooling solutions, Thermal interface materials (TIMs) and heat spreaders.
- Support CFD-based thermal simulations and analysis for high-power GPUs/accelerators, VRMs, and memory subsystems at the board and system level.
- Assist in mechanical design and packaging: 3D CAD models for heatsinks, liquid cold plates, coolant circuits, brackets, backplates, and retention mechanisms.
- Compliance with server/PCIe mechanical constraints and standards.
- Help define and execute thermal validation tests: Sensor placement and logging, Chamber tests, fan speed and airflow characterization, Correlation of test results to simulation models.
- Generate and maintain mechanical drawings, BOMs, and documentation in accordance with internal processes and data center standards.
- Work cross-functionally with PCB, SI/PI, power, and system teams to ensure thermal and mechanical requirements are incorporated early in the design.
Requirements
- Master’s degree in Mechanical Engineering, Aerospace Engineering, or related field.
- 5+ years of relevant experience in thermal and/or mechanical design (internships and project experience acceptable).
- Basic understanding of: Heat transfer and fluid dynamics (conduction, convection, radiation)
- Mechanical design principles and tolerance/stack-up
- Experience with 3D CAD tools (e.g., Creo, SolidWorks, NX, or similar).
- Exposure to thermal simulation tools (e.g., FloTHERM, Icepak, 6SigmaET, Creo Flow Analysis, or similar), even at university or project level.
- Strong problem-solving skills, attention to detail, and willingness to learn in a fast-paced environment.
- Experience involving electronics cooling or data center/server hardware.
- Familiarity with industry standards such as PCIe card form factors, 19" rack systems, or OCP server designs.
- Hands-on lab experience with thermal measurement (thermocouples, IR cameras, etc.).
- Basic scripting skills (Python/Matlab) for data processing and report generation.
Benefits
- A chance to work on one of the most transformative AI and silicon engineering companies in Europe with cutting-edge technology and industry leaders.
- We offer a remuneration package that values your experience.
- We believe in investing in our employees and providing them with opportunities for growth and career development.
- Work in a hybrid environment with flexible scheduling.
- Join an innovative team and experience company growth.
- Opportunity to travel to other countries in Europe to meet the teams, collaborate and drive solutions.
