Thermal Engineer

SeoulOn-siteFull-time

AI Summary

Thermal Engineer defines and validates end-to-end thermal design for NPU/ASIC workloads across package, PCB, card, and system levels, running simulations and tests to ensure cooling solutions meet performance and standards.

About this role

Responsibilities

  • Define end-to-end thermal design across NPU/ASIC package → PCB → card (PCIe FHFL/HHHL, OAM, SXM) → system (server chassis) levels, selecting and designing heatsinks, heat pipes, vapor chambers, cold plates, and TIM

  • Evaluate trade-offs across cooling approaches — air, liquid, 2-phase, and immersion — and run CFD simulations (FloTHERM, Icepak) including EM-thermal co-simulation using power maps from HFSS/SIwave/PowerDC

  • Validate thermal performance through wind tunnel testing, hands-on temperature measurement (thermocouples, IR cameras, RTDs), and DOE-based simulation-to-measurement correlation

  • Support reliability testing including thermal cycling and burn-in

  • Partner with electrical, mechanical, and manufacturing teams to integrate thermal solutions into packaged hardware, and negotiate thermal specifications with OEM/ODM and hyperscale customers

  • Author thermal design guides, reference designs, and test reports, and ensure compliance with form-factor standards (OCP OAM, PCIe CEM, NVIDIA SXM, etc.)

    Minimum Qualifications

  • Thermal Modeling & Simulation: Utilize computational fluid dynamics (CFD) to simulate heat transfer and fluid flow.

  • System Design: Design active and passive cooling solutions, including heatsinks, fans, liquid cooling coldplate.

  • Thermal Testing: Evaluation for NPU card thermal performance with using multi temp recorder and FLIR camera or thermocouples.

  • Collaboration: Work closely with electrical, mechanical, and manufacturing teams to integrate thermal solutions into packaged hardware.

Preferred Qualifications

  • Experienced GPU or NPU card development or server development for datacenter

  • Flotherm or Icepak preferred

  • English communication for business level

  • Positive and proactive engineer
