Lenovo Hiring! Full Time Liquid and Air Cooling Engineer in 台北市, 台灣 - Ricebowl

Key Responsibilities

• Support system-level thermal design and validation for server products, with primary focus on liquid cooling thermal solutions; candidates with strong air-cooling experience are also considered.
• Perform system thermal and acoustic testing, develop test plans, execute validation, analyze test results, and identify potential thermal risks.
• Run thermal simulation and analysis to evaluate thermal feasibility and support system design optimization.
• Work with the BMC / software team to develop and validate fan speed control strategies.
• Support thermal design activities for liquid cooling systems, including components such as CDU, pumps, piping, cold plates, and related cooling components.
• Conduct root cause analysis for thermal and acoustic issues during NPI development and sustaining phases, and drive corrective actions with cross-functional teams.
• Work closely with Mechanical Engineering, BMC, and other engineering teams to optimize system performance, reliability, cost, and manufacturability.
• Collaborate with thermal component suppliers, including fan, heat sink, and liquid cooling solution vendors, to support component evaluation and qualification.
• Participate in regular customer technical meetings and communicate directly with the customer's thermal engineering counterparts on design status, technical issues, test results, and follow-up actions.
• Support approximately one NPI project and one sustaining project concurrently, depending on project assignment.
• Follow and continuously learn internal thermal design processes, product development processes, specifications, and engineering practices.

Requirements

• Bachelor’s degree or above in Mechanical Engineering, Thermal Engineering, Energy Engineering, or a related engineering discipline.
• 3+ years of relevant thermal engineering experience, ideally around 5 years.
• Hands-on experience in system-level thermal design, thermal simulation, and thermal testing.
• Good understanding of fan speed control strategy and system thermal design methodology.
• Experience with server thermal design is preferred; candidates from PC or workstation thermal engineering backgrounds can also be considered.
• Experience in liquid cooling is highly preferred, but strong air-cooling experience is acceptable.
• Familiarity with thermal/acoustic issue debugging and root cause analysis.
• Able to work effectively with cross-functional teams such as Mechanical Engineering and BMC/Firmware.
• Able to communicate in English in technical discussions and customer meetings. Fluent English is not required, but the candidate should be comfortable listening and speaking in meetings.
• Willing to participate in occasional customer meetings outside regular working hours when necessary.
• Occasional business travel may be required, approximately once per year depending on project needs.
