Thermal Analyst
Mechanical Engineer II
NASA Glenn Research Center
Brook Park, Ohio

HX5 is currently seeking an experienced Mechanical Engineer/Thermal Analyst to join our team in Brook Park, Ohio in support of the GEARS contract at NASA Glenn Research Center.

Essential Duties and Responsibilities:

A Thermal Analyst is needed to 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 include building and refining component- and system-level thermal models, designing and executing thermal tests, analyzing resulting data, and translating findings into clear, actionable insights for multidisciplinary engineering teams. The analyst will support the development of thermal management strategies that enable improved performance and operational efficiency for advanced electric propulsion configurations.

Required Skills:

• 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.

Education/Experience:

Mechanical or Aerospace Engineering degree from ABET accredited program with the following education and experience:

• Bachelor's degree and 2 - 5 years of relevant experience
• Master's degree and 0 - 3 years of relevant experience

Other Position Requirements:

• Proof of U.S. Citizenship
• Must be able to complete a U.S. government background investigation
