About Fluidstack

At Fluidstack were building the infrastructure for abundant intelligence. We partner with top AI labs governments and enterprises - including Mistral Poolside Black Forest Labs Meta and more - to unlock compute at the speed of light.

Were working with urgency to make AGI a reality. As such our team is highly motivated and committed to delivering world-class infrastructure. We treat our customers outcomes as our own taking pride in the systems we build and the trust we earn. If youre motivated by purpose obsessed with excellence and ready to work very hard to accelerate the future of intelligence join us in building whats next.

About the Role

As a Mechanical Engineer in the Advanced Engineering group you will architect the future of data center infrastructure designing innovative High and Low Voltage Direct Current (HVDC/LVDC) electrical systems. You will pioneer thermal and magnetic design solutions that ensure the reliable power delivery and operation of millions of GPUs.

Focus

• 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 and power electronics

• 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 for multi-megawatt systems

• Address EMI/EMC shielding creepage/clearance requirements and mechanical integration of power modules capacitors and semiconductor devices in compact high-reliability packages

• Define and execute mechanical and thermal validation testing including structural FEA thermal cycling vibration and environmental qualification for power electronics assemblies

About You

• 7 years of mechanical design experience in power systems high-power electronics or energy infrastructure with strong thermal management background

• Deep expertise in 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) familiar with high-voltage DC systems and NEC UL or IEC standards

• Self-starter who thrives in fast-paced environments and can drive complex thermal-mechanical-electrical integration projects independently with minimal oversight

• Strong understanding of materials for high-power applications including copper/aluminum alloys thermal interface materials potting compounds and high-voltage insulation systems

• Experience with Design For Manufacturing/Assembly principles manufacturing processes (sheet metal machining casting) and bringing designs from prototype through to high-volume production
