Thermal Engineer

The Silicon One team at Cisco creates innovative hardware platforms central to the AI era, powering Cisco’s core Switching, Routing, and Wireless products for organizations globally.

As our Thermal Engineer, you will shape the cooling architectures for next-generation platforms and evaluation boards. You will balance air-cooling and liquid-cooling designs, partnering closely with mechanical, electrical, PCB, SI/PI, and packaging teams.

Operating in our Caesarea lab, you turn thermal simulations into validated hardware solutions, building physical prototypes and measuring thermal margins to ensure robust product performance.

Must Requirements

• Bachelor's degree in Mechanical Engineering or a related engineering field.
• 3+ years thermal engineering experience with electronic products in an R&D environment.
• Experience with thermal simulation tools such as Ansys Icepak, Simcenter FloTHERM, or equivalent.
• Experience planning and conducting thermal tests, thermocouple instrumentation, and test data analysis.

Preferred Qualifications

• Experience with high-power networking, switching, routing, or AI hardware systems.
• Practical experience with liquid cooling, cold plates, or vapor chamber heat sinks.
• Familiarity with thermal management of ASICs, optical modules, and power components.
• Knowledge of 3D CAD tools such as PTC Creo or SolidWorks.

At Cisco, we’re revolutionizing how data and infrastructure connect and protect organizations in the AI era – and beyond. We’ve been innovating fearlessly for 40 years to create solutions that power how humans and technology work together across the physical and digital worlds.
