Employment Type: Full-Time
About the Role
We are seeking a highly skilled Mechanical Engineer to join our Advanced Engineering team. In this role, you will design and develop cutting-edge infrastructure for large-scale GPU data centers, focusing on High and Low Voltage Direct Current (HVDC/LVDC) systems. You will lead mechanical and thermal design initiatives that ensure reliable power delivery and optimal performance for high-power electronics.
Key Responsibilities
- Lead mechanical and thermal design of HVDC/LVDC power distribution systems and high-power electronics for multi-gigawatt GPU data center deployments.
- Design enclosures, structural assemblies, and integrated cooling solutions for high-voltage DC power equipment.
- Perform thermal analysis (CFD) and develop heat dissipation strategies for high-power density systems, including cold plates, heat exchangers, busbars, and airflow management.
- Solve high-current busbar design challenges, including conductor sizing, thermal interface optimization, and electrical contact resistance management.
- Address EMI/EMC shielding, creepage/clearance requirements, and mechanical integration of power modules, capacitors, and semiconductor devices.
- Define and execute mechanical and thermal validation testing, including structural FEA, thermal cycling, vibration, and environmental qualification.
Qualifications
- 7+ years of mechanical design experience in power systems, high-power electronics, or energy infrastructure with strong thermal management expertise.
- Deep knowledge of structural design, heat transfer, CFD analysis, electronics packaging, and outdoor-rated electrical equipment enclosures.
- Proficient in CAD software (SolidWorks, AutoCAD) and thermal simulation tools (Ansys Fluent or similar).
- Familiarity with high-voltage DC systems and relevant standards (NEC, UL, IEC).
- Strong understanding of materials for high-power applications, including copper/aluminum alloys, thermal interface materials, and high-voltage insulation systems.
- Experience with Design for Manufacturing/Assembly principles and manufacturing processes (sheet metal, machining, casting).
- Ability to take designs from prototype through high-volume production.
Compensation
- Salary range: $200,000-$300,000 per year, based on experience, skills, and location.
- Total compensation may include equity options.
- Committed to pay equity and transparency.
