The Senior Thermal Design Engineer leads thermal solution development for CSBU products, including AEC transceivers, cages, and liquid cooling solutions. This role provides technical leadership, influences product architecture through thermal insight, and mentors engineers while working closely with global cross functional teams.

What You Will Do

• Lead thermal design and optimization for air‑cooled and liquid‑cooled electronic products.
• Drive thermal architecture decisions and influence product design through simulation, analysis, and validation.
• Perform advanced thermal simulation, validation, and simulation‑to‑measurement correlation.
• Develop and review thermal validation strategies and test plans.
• Generate comprehensive thermal assessments and present design recommendations to internal and global customers.
• Research and evaluate new cooling technologies, including heatsinks, TIMs, cold plates, two‑phase, and liquid cooling solutions.
• Collaborate with mechanical, electrical, manufacturing, and supplier teams to resolve complex thermal challenges.
• Mentor junior engineers and promote continuous improvement in thermal methodologies and tools.

Who You Are (Basic Qualifications)

• Master’s degree in Thermal Engineering, Mechanical Engineering, or a related field.
• Typically 8+ years of hands‑on experience in thermal design and thermal validation, preferably for server or high‑power electronics.
• Strong experience with both air cooling and liquid cooling thermal solutions.
• Knowledge of cold plate manufacturing processes and electronics cooling technologies.
• Proficiency with thermal simulation tools such as FloTHERM, FloEFD, or Icepak.
• Experience using CAD tools such as NX, Creo, or SolidWorks.
• Ability to lead technical discussions and collaborate effectively in English with global teams.

What Will Put You Ahead

• Experience with servers, switches, optical modules, or AEC transceivers.
• Experience working with liquid cooling suppliers or system integrators.
• Strong project ownership and cross‑functional leadership skills.
• Knowledge of DOE and statistical analysis for thermal optimization.
