• Participate in design reviews, providing thermal expertise and recommendations to ensure designs meet performance requirements.
• Document thermal design processes, simulations, and test results for future reference and knowledge sharing.
• Contribute to project management activities by coordinating thermal engineering efforts, tracking progress, and adhering to project schedules.

Required Qualifications:

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field. A Master’s or Ph.D. in Thermal Engineering or a relevant discipline is often preferred.
• A minimum of 5-7 years of professional experience in thermal engineering within the aerospace, aviation, or related industry.
• Proven track record of designing and analyzing thermal systems for complex engineering projects, preferably including electric aircraft or aerospace systems.
• Experience with thermal simulation tools such as ANSYS Fluent, COMSOL, or similar software to model heat transfer, fluid dynamics, and temperature distributions.
• Proficiency in thermal analysis and heat transfer principles, including conduction, convection, and radiation.
• Familiarity with thermal management technologies, such as cooling solutions, heat exchangers, thermal insulation, and phase change materials.
• Knowledge of thermal regulations and standards relevant to aerospace applications.
• Ability to use CAD software (such as SolidWorks or CATIA) to collaborate on thermal design integration.
• Strong problem-solving skills to identify and address thermal challenges effectively.
• Ability to work within cross-functional teams and collaborate with engineers from various disciplines.

Preferred Qualifications:

• Experience in eVTOL aircraft projects or electric propulsion systems.
• Familiarity with battery thermal management systems, motors, and propulsion systems and their integration in aerospace applications.
• Familiarity with FAA 14 CFR Part 91 regulations.
• Experience with FAA airworthiness certifications and requirements (Part 23 and/or Part 27).
• Familiarity with problem reporting and task tracking systems (e.g. JIRA).
• Familiarity with requirements capture and tracking software (e.g JAMA).
