Thermodynamics Engineer

Start the Best Work of Your Career at Boom

At Boom, we’re redefining what’s possible in aerospace. From our XB-1 supersonic demonstrator to Overture, our revolutionary commercial airliner, we’ve proven that ambitious goals can be achieved by small, high-performing teams solving hard problems with precision, innovation, and bold execution.

We’re seeking a Thermodynamics Engineer to lead the development and integration of advanced thermal modeling across the full aircraft. This is not a typical thermal analysis role—you will architect and maintain comprehensive models, create specialized tools, and guide critical thermal trade studies that affect everything from skin heating at Mach speeds to passenger comfort and propulsion system efficiency.

You'll work across engineering domains, bringing together data and insight from Propulsion, Environmental Control Systems (ECS), Fuel Systems, Structures, and beyond. Your work will directly inform system architecture, flight safety, and energy management strategies in a high-performance, supersonic environment.

Role Overview

As a core member of our multidisciplinary Flight Sciences team, you will:

• Develop and maintain a full-aircraft thermal model that incorporates skin heating at supersonic cruise, system heat sources, and passenger heat loads
• Model and analyze steady-state and transient thermal conditions across diverse environments and mission phases
• Create and maintain tools for sizing and assessing bleed air demand, ECS load distribution, propulsion system heat transfer, and fuel system heating/cooling
• Support the definition and validation of cabin climate control strategies, avionics cooling, and propulsion integration thermal margins
• Collaborate with Aerodynamics, Propulsion, Structures, and Systems teams to ensure proper thermal protection, heat rejection, and system integration across the aircraft
• Lead thermal-related trade studies to support design decisions, system optimization, and mass/energy balance closures
• Integrate thermal modeling with broader simulation frameworks (e.g., MATLAB, Simulink, Python-based toolchains)
• Support testing, instrumentation planning, and correlation of thermal models with ground and flight test data
• Ensure designs and models align with certification requirements under 14 CFR Part 25

The Ideal Candidate

• Bachelor’s or higher degree in Aerospace Engineering, Mechanical Engineering, Physics or a related field
• Experience in thermal systems modeling and analysis for aerospace vehicles or comparable high-performance systems
• Strong understanding of thermodynamics, heat transfer (conduction, convection, radiation), and fluid dynamics
• Familiarity with high-speed aircraft skin heating environments and ECS/bleed air systems
• Proficiency in modeling tools such as MATLAB, Python, Simulink, and relevant thermal analysis software (e.g., SINDA/FLUINT, Thermal Desktop, or ANSYS)
• Excellent communication and collaboration skills; comfortable working across disciplines
• Demonstrated ability to lead or significantly contribute to system-level studies and integrated design efforts

What Will Set You Apart

• Experience with supersonic aircraft or other high-speed vehicle thermal environments
• Hands-on experience with thermal model validation using test data
• Experience developing custom thermal analysis tools and utilities
• Familiarity with fuel system thermal management, ECS architecture, and propulsion cooling loops
• Background in certification processes and compliance documentation for thermal systems
• Demonstrates a strong work ethic and ambition, complemented by effective collaboration skills in a team setting
• Excels in a high-energy, independent, and challenging work environment

Why Boom

Boom is building something the world has never seen—a return to supersonic commercial flight. If you're driven to solve complex thermal challenges that span structural heating, environmental control, and propulsion integration, this is your opportunity to shape the future of aviation.

Compensation
