About Celestica
If you're reading this, chances are you're connecting through at least one piece of hardware that we designed, developed, manufactured, or service. Celestica is the brand behind the brands you rely on every day. Through our Hardware Platform Solutions (HPS), we engineer and deliver leading-edge networking, storage, and server platforms-powering everything from custom hyperscale cloud deployments to the world's most demanding AI, machine learning, and 5G infrastructure. Across global data centers and enterprise environments, we partner with industry leaders: 9 of the top 10 internet service providers, 4 of the top 5 storage providers, 3 of the top 5 networking OEMs, and the top 3 non-X86 server providers.
At Celestica, our people drive this scale. We are a team of changemakers who combine deep engineering expertise with an unrelenting drive to solve complex architectural challenges for our customers. As AI workloads push silicon and power boundaries past historical limits, traditional cooling is no longer enough. Thermal engineering and advanced liquid cooling are now the critical enablers of the next generation of computing.
Job Summary
Reporting directly to the Engineering Director, the Senior Manager, Thermal Engineering, leads a high-performing engineering team responsible for defining thermal architecture and cooling strategies for next-generation, high-power AI compute platforms. In this high-impact, collaborative leadership role, you will work closely with cross-functional partners, global customers, manufacturing teams, and senior executives to drive the end-to-end development and deployment of state-of-the-art liquid cooling solutions for hyperscale data centers.
As a supportive functional leader, you will empower your team to innovate across advanced 1D fluidic modeling, computational fluid dynamics (CFD) simulation, and complex thermal validation. Beyond concept design and thermal/hydraulic qualification, you will provide strategic executive and technical guidance throughout the entire manufacturing life cycle, fostering an inclusive environment while ensuring high-reliability cooling systems meet rigorous performance, efficiency, and operational standards.
If you are driven to lead an elite engineering team at the absolute frontier of data center liquid cooling and hardware innovation, let's engineer the future together.
Detailed Description
