Job Description

• Thermal Design: Heatsink topology, vapor chambers, heat pipes, fin optimization; fan selection and control; ducting; altitude derating; PoE PSU thermal integration (e.g., 1100W).
• CFD Expertise: Geometry prep, meshing strategy, solver settings, turbulence models (k‑ε/k‑ω), boundary condition fidelity; correlation methods and uncertainty analysis.
• FEA/Structural: Static, modal, buckling, fatigue; fixture/constraint realism; shock/vibe spectra; fastener/joint analysis; compliance with GR‑63.
• Mechanisms & Kinematics: Latches, ejectors, guides, hinges, detents; ergonomics and tactile feedback; wear and tolerance sensitivity.
• EMC‑Aware Mechanics: Shielding architectures, gasket compression, seam leakage control, conductive finishes, grounding paths.
• GD&T & Tolerance Analysis: Datum strategy, stack‑up spreadsheets, worst‑case/RSS methods;
• CMM validation; manufacturable callouts.
• Materials & Finishes: Thermal and stiffness trade‑offs; corrosion and galvanic pairs; finish impacton conductivity/emissions; recyclability.
• DfM/DfA: Sheet‑metal (bends, hems, tabs), die casting (draft/overflow), injection molding (gates,knit lines), secondary ops minimization; Poka‑Yoke features.
• TIMs & Interfaces: Compression targets, surface flatness, roughness; long‑term stability; rework/service considerations.
• Acoustics: Fan tone management, damping/isolators; measurement protocols; psychoacoustic considerations.
• Reliability & Environment: HALT/HASS, salt‑fog, dust/ingress, humidity, temperature cycling; packaging/drop compliance.
• Documentation Excellence: Clear build guides, service manuals with HMI cues, exploded views, torque specs, and safety notices.

Required Skills & Tools:

• CAD: Creo, SolidWorks, or NX; PDM/PLM (e.g., Agile/Windchill)
• Analysis: CFD (6Sigma/Flotherm/Icepak), FEA (Ansys/Nastran)
• Standards: NEBS, IEC/UL, RoHS/REACH, IP/ingress
• Methods: DfM/DfA, GD&T, Tolerance Analysis, RCCA/8D
• Expertise in Sheet‑metal, die casting, injection molding, thermal interface materials (TIMs), heatsinks/vapor chambers

Qualifications:

• Bachelor’s/master’s in mechanical engineering
• 15+ years in mechanical design for networking or server-class hardware
• Experience with high-power thermal solutions and acoustic optimization
