Key job responsibilities
Mechanical architecture
Define the mechanical architecture for the 5–10 MW system and its major assemblies.
Develop rack/enclosure concepts compatible with high-power electronics and liquid cooling.
Define mechanical interfaces with power, PCB, magnetics, cooling and electrical integration.
Environmental requirements
Address IP-rating requirements.
Define and assess vibration and seismic qualification requirements.
Consider serviceability, accessibility and maintainability in the mechanical design.
Design leadership
Lead mechanical design reviews.
Coordinate suppliers and manufacturing for prototype and production parts.
Support mechanical qualification, prototype builds and system integration.
SST System Alignment"
Design against the system specification environmental envelope where applicable: NEMA 3R outdoor rating, -30°C to 40°C operating range, C5 corrosion class, 95% RH non-condensing, ≤1000 m site elevation and defined transport/seismic loads.
Account for the system physical envelope guidance and serviceability/transport constraints while developing the 5–10 MW platform.
A day in the life
As a Lead Mechanical Engineer, you'll focus on developing mechanical architecture for our 5-10 MW power systems, working with cutting-edge liquid cooling and high-power electronics integration. Your day might include chairing mechanical design reviews where you evaluate structural and thermal concepts, coordinating with suppliers on prototype development, or mentoring junior designers through complex design challenges. You'll balance strategic architecture decisions with hands-on problem-solving—defining how components interface with electrical, thermal, and manufacturing teams. You'll also assess environmental requirements like vibration and seismic qualification, ensuring our systems operate reliably across diverse global locations from coastal to high-altitude environments.
