Responsibilities

• Own thermal design and analysis of avionics components, including PCBAs, COTS electronic devices, and custom enclosures.

• Predict and manage junction temperatures, heat spreading, coldspots, and hotspots under mission-relevant conditions.

• Provide guidance on component placement, stackups, copper, and via strategies for optimizing thermal performance.

• Design conduction paths and interfaces (PCB → chassis, TIMs, contact resistances).

• Plan and execute board-level thermal testing and model correlation (thermocouples, IR, model validation).

Basic Qualifications

• Experience in electronics/PCB thermal analysis (avionics, power electronics, or similar).

• Strong grasp of conduction and radiation-dominated heat transfer and transient thermal behavior.

• Proficiency with thermal tools (Icepak, Fluent, Thermal Desktop, or equivalent).

• Experience with thermal testing and validation of electronics hardware.

• Ability to work cross-functionally with software, electrical, and mechanical teams.

Preferred Qualifications

• Experience optimizing PCB layout for thermal performance (placement, planes, vias).

• Background in avionics or embedded electronics thermal design.

• Experience with high power-density or transient thermal loads.

• Experience with heat sink design.

• Experience with high altitude or space systems.

• Familiarity with chassis/enclosure integration and low-convection environments.

• Experience building custom analysis tools (Python/MATLAB) or rapid trade studies.
