Job description

Hiring for a 5-6 months hyrbid role in Fremont (94538). Regular, Mon-Fri, 40 | 8am-5pm PST, 3 days in office & 2 days remote.

Top Skills:

• Strong expertise in thermal management, heat transfer, and precision thermal systems.
• Experience developing and validating thermal models using experimental data.
• Hands-on experience with hardware instrumentation, thermal testing, and laboratory experimentation.

We are seeking a highly motivated Thermal Engineer to lead the characterization and modeling of a thermal control assembly consisting of embedded heaters and a liquid-cooled plate. The primary objective is to develop a physics-based and experimentally validated transfer function that predicts thermal performance when transitioning between two specified coolant formulations.

The successful candidate will design and execute experiments, develop analytical and computational models, correlate model predictions to measured results, and establish methodologies for predicting temperature uniformity, thermal transients, and steady-state thermal behavior across varying operating conditions.

This role requires strong expertise in heat transfer, thermal management, instrumentation, data analysis, and engineering problem-solving. The position involves both hands-on laboratory work and advanced modeling activities.

Key Responsibilities

• Characterize thermal performance including:
• Mean operating temperature
• Spatial thermal gradients
• Thermal transition and settling behavior
• Design experiments to isolate and quantify key thermal parameters and mechanisms.
• Specify and implement thermal instrumentation including thermocouples, RTDs, flow sensors, pressure sensors, and infrared cameras.
• Evaluate the impact of coolant properties, flow conditions, thermal interfaces, and hardware tolerances on system performance.
• Develop analytical and computational thermal models of multi-component assemblies.
• Develop and validate transfer functions to predict thermal performance differences between two specific coolants.
• Correlate experimental data with simulation results and improve model accuracy.
• Develop automated analysis tools and data processing workflows using Python or MATLAB.
• Generate technical reports and present conclusions to engineering and management teams.

Required Qualifications

• M.S. or Ph.D. in Mechanical Engineering, Aerospace Engineering, Chemical Engineering, Applied Physics, or related discipline.
• 5+ years of experience in thermal engineering, heat transfer, or thermal management systems.
• Strong expertise in thermal management, heat transfer, and precision thermal systems.
• Experience developing and validating thermal models using experimental data.
• Hands-on experience with hardware instrumentation, thermal testing, and laboratory experimentation.
• Proficiency with Python and/or MATLAB for data analysis and model development.
