Sr. Staff Mechanical Engineer

What You Will Do

• Lead mechanical design for our AI inference hardware platform at rack scale, in compliance with OCP specifications.
• Design and validate chassis mechanical systems, sheet metal enclosures, cooling architectures, and high-power connections.
• Own the full product lifecycle — from design and validation through NPI to mass production.
• Conduct mechanical reliability testing (shock, vibration, thermal cycling) and lead 3D modeling, FEA, and tolerance analysis to validate designs for manufacturability.
• Partner with suppliers, ODMs, CMs, and JDMs to develop custom mechanical/thermal components and manage manufacturing support through production ramp.
• Debug and resolve quality issues surfaced during NPI and production, driving root-cause analysis and corrective action.
• Review and sign off on liquid-cooled cold plate and manifold integration at the rack level (design owned by the Card & Sub-Chassis Mechanical Engineer), ensuring compatibility with CDU interfaces and facility water connections.
• Develop specifications and test procedures for reliability and performance and mentor engineers across the design lifecycle.
• Evaluate new technologies and methodologies to improve mechanical and thermal performance and ensure compliance with quality standards through product launch.
• What You Will Bring
• Bachelor’s degree in mechanical engineering or a related field.
• 10+ years of industry experience in mechanical design, simulation, and validation for IT hardware, with demonstrated technical leadership of full rack-scale programs.
• Hands-on experience with OCP specifications and rack-scale system design.
• Strong background in chassis mechanical design, sheet metal design/fabrication, and design-for-manufacturability (DFM) at high volume.
• Experience running and interpreting shock and vibration testing.
• Proven track record taking designs from concept through validation to mass production (NPI to MP).
• Direct experience working with suppliers, ODMs, CMs, and/or JDMs on hardware development.
• Strong debugging and root-cause analysis skills for mechanical/quality issues in production environments.
• Proficiency in CAD tools and FEA.
• Expertise in GD&T and tolerance stack-up analysis, and materials selection for structural and thermal performance in chassis/enclosure design.
• Self-driven and detail-oriented, comfortable working independently or across engineering teams.
• Preferred Qualifications
• Master’s degree in mechanical engineering or related field.
• 15+ years of industry experience in mechanical design, simulation, and validation for IT hardware.
• Experience with data center hardware or high-performance computing systems at scale.
• Familiarity with liquid-cooled rack architectures (cold plates, manifolds, CDUs, facility water interfaces) sufficient to review and integrate card-level cooling designs at the rack level.
• Direct hands-on cold plate or manifold design experience, beyond rack-level integration.
• Deep understanding of reliability testing, failure analysis, and thermal stress modeling for electronic components.
