What are the key skills and qualifications needed to thrive as a Thermal Engineer, and why are they important?

To thrive as a Thermal Engineer, you need a solid background in thermodynamics, heat transfer, and fluid mechanics, typically supported by a degree in mechanical or thermal engineering. Familiarity with simulation tools such as ANSYS, MATLAB, and CAD software, as well as relevant certifications like Professional Engineer (PE), is highly valuable. Strong problem-solving abilities, attention to detail, and effective communication skills help you excel in multidisciplinary teams and complex projects. These competencies ensure accurate system designs, efficient thermal solutions, and successful project outcomes in industries ranging from aerospace to electronics.

How do thermal engineers typically collaborate with other engineering disciplines on large-scale projects?

Thermal engineers often work closely with mechanical, electrical, and civil engineers to ensure that thermal systems integrate smoothly into broader project designs. Collaboration usually involves regular meetings, sharing simulation data, and coordinating design changes to optimize energy efficiency and safety. Effective communication and teamwork are essential, as thermal engineers must align their solutions with structural limitations, electrical requirements, and overall system goals. This cross-functional interaction not only enhances project outcomes but also provides valuable opportunities for professional growth and knowledge sharing.

What is thermal engineering?

Thermal engineering is a branch of engineering that focuses on the study, design, and management of systems and processes involving heat transfer and energy conversion. Thermal engineers work on technologies such as heating and cooling systems, engines, power plants, and thermal management in electronics. Their work helps improve energy efficiency, safety, and sustainability in various industries including automotive, aerospace, manufacturing, and HVAC. They apply principles of thermodynamics, heat transfer, and fluid mechanics to solve real-world engineering challenges.

What is the difference between Thermal Engineering vs Mechanical Engineering?

AspectThermal EngineeringMechanical Engineering
FocusHeat transfer, thermodynamics, HVAC systems, energy systemsDesign, analysis, manufacturing of mechanical systems, machinery, and tools
CredentialsBachelor's or master's in Mechanical or Thermal EngineeringBachelor's or master's in Mechanical Engineering
Work EnvironmentResearch labs, manufacturing plants, energy sectorsFactories, design firms, R&D departments
Industry UsagePower plants, HVAC, aerospace, automotiveAutomotive, aerospace, manufacturing, robotics

Thermal Engineering specializes in heat transfer, thermodynamics, and energy systems, while Mechanical Engineering covers a broader range of mechanical design and manufacturing. Both fields share similar credentials and work environments but differ in their specific focus areas and industry applications.

Job description

The Aerospace Corporation is the trusted partner to the nation's space programs, solving the hardest problems and providing unmatched technical expertise. As the operator of a federally funded research and development center (FFRDC), we are broadly engaged across all aspects of space- delivering innovative solutions that span satellite, launch, ground, and cyber systems for defense, civil and commercial customers. When you join our team, you'll be part of a special collection of problem solvers, thought leaders, and innovators. Join us and take your place in space.

The Vehicle Systems Division (VSD) sits at the center of the ideas and data behind current and future systems supplying innovative research and development; technical evaluations during the acquisition process; conceptual and detailed design; assembly, integration, and test; and operational support. Comprised primarily of highly-trained mechanical and aerospace engineers, VSD provides national expertise in the areas of vehicle engineering; guidance, navigation, and controls; robotics; electro-mechanical devices; embedded systems; fluid mechanics; propulsion; thermal control; orbital mechanics; mechanisms; structures; structural dynamics; and dynamic environments.

The Thermal Control Department is a team of experienced, trusted engineers with deep expertise in the design and analysis of spacecraft thermal control systems from component to system level. The department performs technical studies, experimental investigations, and real-time assessments to inform and enable key decisions by our customers and their contractors.

We are looking for a Spacecraft Thermal Engineer (Sr. Member of Technical/Engineering Specialist - Aeronautical and Mechanical Engineering) with a strong background in the disciplines of heat transfer and thermal engineering and their applications to space systems; and direct experience in thermal design and control of spacecraft. The successful applicant will support both classified and unclassified spacecraft programs with emphasis on classified systems. They will engage and advocate for the best solutions, best practices, and best innovations for critical thermal control issues across the enterprise, both inside and outside Aerospace.

This is a full-time position based in Chantilly, VA, or El Segundo, CA.

What You'll Be Doing

  • Key customers are internal program offices representing defense and civil agencies, such as the U.S. Space Force, the National Reconnaissance Office (NRO), the National Aeronautics and Space Administration (NASA), and others

  • You will engage with impact with these internal and external customers to identify, track, and resolve design, workmanship, and performance issues relating to space vehicle and payload thermal control subsystems

  • You will deliver results as the thermal subject matter expert in thermal control systems for spacecraft and payloads. Lead and conduct analysis, modeling, simulation, experimental investigations, and assessments of designs and design concepts relating to spacecraft thermal control systems and their components. Participate in and review thermal subsystem requirements, allocations, design, integration, test, and flight operations

  • You will operate strategically, curating department knowledge and capabilities in thermal systems engineering, thermal analysis and design, and/or thermal control hardware

  • You will provide thermal engineering technical leadership of teams of 2 or more people in support of programs, interdepartmental projects, and broad engagement efforts

What You Need to be Successful

Minimum Requirements for Sr. Member of Technical Staff:

  • Bachelor's degree in a STEM related field

  • 4 years or more of thermal engineering experience

  • Experience providing thermal engineering support at a system level for at least 2 different spacecraft programs, encompassing at least two major phases (e.g., Architecture, Design, Manufacturing, Test, Flight) for each program

  • Ability to obtain and maintain a US security clearance, which is issued by the US government. US citizenship is required

In addition to the requirements above, the minimum requirements for Engineering Specialist - Aeronautical and Mechanical Engineering:

  • 8 years or more of total thermal engineering experience

  • Experience leading integrated-team thermal engineering efforts: innovation projects, concurrent engineering, digital engineering, vehicle-level thermal design, hosted or multiple-payload missions, anomaly and root-cause investigation involving 2 or more people
