About The Position

The Thermal Engineer leads thermal architecture, analysis, and validation across complex hardware platforms. This role drives cooling strategy, owns thermal risk management, and ensures products meet performance and reliability targets through simulation, testing, and cross-functional problem solving.

The engineer leads cooling-system design strategy, performs advanced thermal simulation and analysis, defines validation plans and acceptance criteria, drives root-cause analysis and corrective actions, identifies and mitigates thermal risks, and communicates performance, gaps, and status to stakeholders. The role also partners across engineering functions, mentors junior engineers, and contributes to thermal methods, standards, and best practices.

Requirements

• Bachelor’s degree in Mechanical Engineering, Thermal Engineering, or a related technical field.
• 5–10 years of relevant experience in thermal design, cooling architecture, analysis, and validation of complex hardware systems.
• Strong expertise in CFD or equivalent thermal modeling techniques and interpretation of system-level thermal behavior.
• Experience defining and executing thermal validation plans and driving technical issue closure across product programs.
• Familiarity with server, storage, networking, AI infrastructure, or other high-power electronics products.
• Strong analytical skills and ability to communicate technical risk, data, and recommendations clearly.
• Demonstrated ability to lead technical efforts across matrixed, cross-functional engineering teams.

Nice To Haves

• Master’s degree.

Responsibilities

• Lead thermal design strategy for platform cooling systems, including airflow architecture, heatsink solutions, fan strategy, and thermal control considerations.
• Own advanced thermal simulation and analysis activities to validate design direction and system layout performance.
• Define thermal validation scope, plans, schedules, and acceptance criteria aligned to product and customer requirements.
• Drive root-cause analysis and corrective actions for thermal issues found during design, validation, builds, or field feedback loops.
• Identify thermal risks early, develop mitigation and contingency plans, and communicate trigger conditions and closure plans to stakeholders.
• Partner with Mechanical, Electrical, Firmware, Systems, and Validation teams to ensure cross-functional decisions support reliable thermal performance.
• Publish thermal performance reports, gap assessments, and status updates that enable timely program decisions.
• Mentor junior engineers and contribute to thermal methodology, standards, and best-practice development.
