Mechanical Engineer - Thermal Design

Bachelor's or Master's degree in Mechanical Engineering, Mechatronics, or a related field.

4–7 years of experience in thermal design and analysis for electronic systems, ideally rugged, sealed, or harsh-environment hardware.

Proficiency in SolidWorks.

Experience with thermal simulation and CFD tools (ANSYS Icepak or Fluent,

Simcenter FloTHERM, SolidWorks Flow Simulation, or similar).

Strong understanding of heat transfer fundamentals (conduction, convection, radiation) and thermal management techniques for electronics, such as heat sinks, heat spreaders, heat pipes, thermal interface materials, and conduction paths.

Knowledge of materials and manufacturing processes relevant to thermal hardware, such as machining, extrusion, and die casting.

Experience with thermal test methods and instrumentation (thermocouples, IR thermography, environmental chambers) and correlating test results to models.

Familiarity with environmental test standards for rugged electronics (e.g., MIL-STD- 810).

Ability to produce clear technical documentation and engineering drawings.

Experience designing thermal hardware that works reliably in sub-zero environments

Ability to design passive cooling and heating solutions that minimize power draw
