Job summary

Everforth Apex in Fremont, CA is seeking a Thermal Engineer to lead characterization and modeling of a liquid‑cooled thermal assembly with embedded heaters. You will develop a physics‑based transfer function to predict performance when switching between two coolant formulations.

The role requires hands‑on lab work, advanced modeling, and development of automated analysis tools in Python or MATLAB. Hybrid work arrangement in a fast‑paced engineering environment.

Qualifications

• MS or PhD 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.
• Proficiency with Python and/or MATLAB for data analysis and model development.
• Hands-on experience with hardware instrumentation and thermal testing.
• Experience developing and validating thermal models using experimental data.

Responsibilities

• Characterize thermal performance including mean temperature, uniformity, spatial gradients, and thermal transition behaviour.
• Design experiments to isolate and quantify key thermal parameters.
• Specify and implement thermal instrumentation (thermocouples, RTDs, flow/pressure sensors, IR cameras).
• Develop analytical and computational thermal models for multi-component assemblies.
• Develop and validate transfer functions to predict thermal performance differences between two coolants.
• Correlate experimental data with simulations and improve model accuracy.
• Create data processing workflows using Python or MATLAB and generate technical reports.
