Power Architect - AI Server & Rack Power Systems
Job Summary
The Power Architect defines end‑to‑end architecture for power connectors, power whips, and liquid‑cooled busbar systems in AI servers and racks, meeting stringent performance, reliability, safety, and scalability requirements. The role partners with Sales, PLM, and R&D on roadmaps and customer engagements, ensures compliance with IEC/IEEE and thermal/seismic standards, and represents the company in industry consortia (OCP, OIF, IEEE). The architect tracks emerging technologies to boost power density, efficiency, and total cost of ownership.
Essential Duties & Responsibilities
- Design & Optimization: Architect rack/server‑level power distribution (connectors, cables, busbars, whips) for high‑current applications (130-3,000 A), ensuring alignment precision (±1.00 mm), thermal efficiency, serviceability, and reliability in dense GPU/TPU environments (100 kW-1 MW/rack).
- Power Estimation & Modeling: Develop and maintain rack/server power estimation tools; lead perf‑vs‑power trade‑offs, Perf/Watt improvements, and early architectural exploration in partnership with hardware/firmware/software teams.
- Compliance & Standards: Ensure conformity to IEC 61439 and relevant IEEE/safety standards, including seismic, short‑circuit (e.g., 25 kA) and operating temperature requirements (40°C to +125°C).
- Cross‑Functional Collaboration: Align product roadmaps with AI infrastructure demands (e.g., NVIDIA/AMD/Intel GPU power envelopes) and customer requirements; support SEs and Sales with reference architectures and TAM/SOW inputs.
- Innovation & Trends: Integrate liquid‑cooled busbars, low‑GWP cooling, advanced copper alloys, and novel connector systems to elevate power density, efficiency, and maintainability.
- Industry Engagement: Contribute to/lead workstreams in OCP, OIF, and IEEE; leverage open standards and reference designs for faster qualification and deployment.
Required Qualifications
- Education: Bachelor's in Electrical Engineering, Mechanical Engineering, Power Systems, or related field.
- Experience: 10-15 years in power architecture for high‑density systems (rack‑scale 100 kW-1 MW), ideally in AI/ML or HPC data centers.
- Technical Depth:
- Power connector/busbar design (liquid‑cooled, solder‑tail, screw‑mount) and high‑current distribution up to ~3,000 A.
- Thermal management for AI workloads (air/liquid), pressure drop/flow considerations, and interface materials.
- Proficiency with IEC/IEEE standards, short‑circuit withstand/coordination, creepage/clearance, and protection schemes.
- CAD/CAE and simulation (electro‑thermal, CFD, FEA) and system‑level validation/qualification (e.g., 25 kA SCCR).
- Ecosystem Collaboration: Experience working with OEMs, hyperscalers, and chip vendors (NVIDIA, AMD, Intel) and data center operators on rack/server power delivery.
- Communication: Ability to translate complex trade‑offs to executives, customers, and engineering teams.
Preferred Qualifications
- Master's/PhD in Power Mechanics, Thermal Engineering, Applied Physics, or related field.
- Knowledge of BBU/powershelf architectures, dynamic workload/power capping, and rack‑scale controls.
- Familiarity with AI reference architectures (e.g., designs suppo
