About the role

Thermal Engineer to own thermal design and analysis for advanced defense hardware across drones, aircraft, missiles, and related flight systems, based in Costa Mesa, CA.

Responsibilities

  • Own thermal design and analysis for integrated hardware products, including drones, aircraft, missiles, or related defense systems.
  • Use first-principles engineering judgment to determine the right level of analysis for each design decision, including hand calculations, spreadsheets, MATLAB / Python models, FEA, and CFD.
  • Define thermal architectures that can withstand rugged environments, demanding flight envelopes, and operational edge cases, including hot, cold, transient, and mission-specific thermal conditions.
  • Partner with electrical, mechanical, aerospace, software, and systems engineers to document power dissipation, operating modes, thermal constraints, and design tradeoffs.
  • Build and maintain thermal FEA / CFD models to predict system performance, establish design limits, and define red / yellow operating thresholds for test and field use.
  • Define and execute prototype builds and thermal tests, including CAD support, sensor selection, DAQ setup, data post-processing, and results documentation.
  • Present thermal status, risks, tradeoffs, timelines, and recommendations in internal design reviews and customer-facing technical reviews.
  • Develop internal tools, workflows, or analysis methods that improve speed, consistency, and quality of thermal decision-making.
  • Support failure reviews and root-cause investigations using test data, thermal analysis, and first-principles reasoning.

Qualifications

  • MS or PhD in Mechanical Engineering, Aerospace Engineering, Applied Physics, or a related field with a focus on heat transfer, fluid dynamics, thermal sciences, or thermal systems.
  • 2+ years of experience designing, analyzing, or validating thermal systems for integrated hardware products.
  • Strong first-principles understanding of heat transfer and fluid dynamics, including conduction, convection, radiation, fluid flow, and transient thermal behavior.
  • Experience supporting thermal design for aerospace, aircraft, rocket, missile, UAV, defense, or other high-performance hardware systems.
  • Experience using thermal analysis, modeling, simulation, and/or physical test data to drive design decisions for passive or active thermal management systems.
  • Ability to communicate technical tradeoffs clearly across engineering, program, and customer stakeholders, and ability to obtain and maintain a U.S. Top Secret security clearance.
