Your Impact

Do you want to solve complex cooling challenges in innovative AI hardware? 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.
