Position OverviewWe are seeking a
Principal Early Supplier Involvement (ESI) Engineer to drive hardware co-design, manufacturability, and supply chain readiness for our next-generation
Data Center AI Infrastructure platform.
In this role, you will act as the technical bridge between our System Architects, Mechanical/Thermal/Electrical Engineering teams, and strategic technology suppliers. You will engage with partners early in the concept phase (Phase 0/1) to de-risk high-density thermal architectures, complex high-speed PCBAs, and high-power delivery systems. Your goal is to ensure our AI computing systems achieve industry-leading time-to-market, uncompromised quality, and scalable cost-to-manufacture.
Key ResponsibilitiesAI Hardware Co-Design & Technical Integration- Advanced Thermal & Liquid Cooling DFM: Partner with liquid cooling suppliers (CDUs, cold plates, quick disconnects/QDCs, manifolds) to review fluid dynamics, materials compatibility, leak-mitigation designs, and high-volume manufacturability.
- High-Speed PCBA & Custom Interconnects: Conduct early DFM/DFT reviews with EMS partners and substrate/PCB suppliers for complex AI accelerator boards, PCIe Gen 6/7, and optical interconnects (high layer-count PCBs, microvias, HDI).
- Power Delivery Systems: Collaborate with power supply and busbar manufacturers to optimize ultra-high-density power distribution units (PDUs), power shelves, and voltage regulator modules (VRMs) for 100kW+ rack architectures.
- Rack-Level Mechanical & Structural Integration: Work with chassis and rack-fabrication suppliers to ensure structural integrity, tolerance stack-up analysis (GD&T), and blind-mate blind-connector alignment.
Prototyping, Ramp, & Risk Mitigation- Rapid NPI Prototyping: Oversee prototype builds with primary suppliers to accelerate engineering validation test (EVT) and design validation test (DVT) cycles.
- Single/Sole-Source De-Risking: Identify single-point-of-failure components early in the CAD/schematic lifecycle and drive second-source qualifying pathways or modular redesigns.
- Should-Cost & Process Yield Modeling: Analyze early component geometry, material selection, and process flows (e.g., skived vs. stamped cold plates, high-frequency laminates) to build accurate cost models and maximize production yields.
Qualifications & Requirements- Education: Bachelor's or Master's degree in Mechanical Engineering, Electrical Engineering, Materials Science, or Manufacturing Engineering.
- Experience: 4-8+ years in NPI engineering, hardware design, supplier technical development, or DFM for high-density compute, networking, or data center hardware.
- Technical Expertise:
- Hands-on experience with liquid cooling technologies (direct-to-chip, immersion, CDUs) or high-power/high-speed server architecture.
- Advanced knowledge of GD&T, CAD software (Creo, SolidWorks, or Siemens NX), and tolerance stack-up analysis for server chasses and rack enclosures.
- Direct experience conducting DFM reviews with Tier-1 EMS, PCB fabricators, and custom mechanical/thermal vendors.
- Soft Skills:
- Ability to communicate effectively across cross-functional boundaries-translating high-level AI system requirements into actionable supplier specifications.
- Strong negotiation and technical decision-making skills in high-pressure, fast-paced environments.
Preferred Qualifications- Deep understanding of high-frequency materials (e.g., Megtron 6/7/8) and high-density interconnect (HDI) manufacturing.
- Familiarity with Telcordia, OCP (Open Compute Project) standards, and NEBS compliance.
- Experience with automated should-cost tools (e.g., aPriori) and PLM systems (Agile, Windchill).
