Thermal Analyst

HX5 is an award-winning provider of engineering, research and development, and technical services to clients such as NASA and the Department of Defense. Founded in 2004, HX5 is a fast-growing veteran and woman-owned company with locations nationwide.

About the role

The Mechanical Engineer/Thermal Analyst will support development activities for a small aircraft serving as a flexible flight research platform for emerging electric, mechanical, thermal, and acoustic technologies relevant to next-generation eVTOL systems. The platform is intended to generate real-world flight data across a variety of propulsion and system-integration configurations, including advanced motors, converters, batteries, and associated thermal subsystems. This work builds on NASA’s prior electric and hybrid-electric research efforts and supports ongoing activities within the Vehicle System Powertrain and Motor Systems team.

The selected engineer will work with NASA technical leads and engineers to develop a comprehensive thermal model of critical heat-generating components such as motors and power converters. This model will guide the development of optimized thermal solutions aimed at reducing system size and weight while achieving reliable thermal performance. The position also contributes to broader powertrain integration and system-level thermal design and validation efforts.

Responsibilities

• Build and refine component- and system-level thermal models.
• Design and execute thermal tests.
• Analyze resulting data and translate findings into clear, actionable insights for multidisciplinary engineering teams.
• Support the development of thermal management strategies that enable improved performance and operational efficiency for advanced electric propulsion configurations.

Requirements

• Thermal system analysis experience using ANSYS Thermal Desktop, Fluent, or equivalent predictive thermal analysis tools.
• Capability to design and execute thermal tests in laboratory environments.
• Strong data analysis skills with the ability to communicate findings clearly to engineering stakeholders.
• Knowledge of aeronautic thermal control techniques and their application to electrified propulsion systems.
• Mechanical or Aerospace Engineering degree from ABET accredited program:
  • Bachelor's degree and 2 - 5 years of relevant experience
  • Master’s degree and 0 - 3 years of relevant experience
• Proof of U.S. Citizenship
• Must be able to complete a U.S. government background investigation
