Thermal & Mechanical Design Engineer - Accelerator Boards

The Role :

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.

This is an excellent opportunity for an engineer to get hands‑on experience with cutting‑edge data center hardware and learn from senior experts.

Key Responsibilities :

• 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 cirquits, 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.
