Propulsion System Design Engineer information

What are some common challenges faced by propulsion system design engineers when integrating new technologies into existing systems?

Propulsion System Design Engineers often encounter challenges when integrating new technologies, such as ensuring compatibility with existing subsystems, meeting stringent safety and regulatory standards, and managing weight or space constraints. Collaboration with cross-functional teams—including structural, thermal, and controls engineers—is essential to address these issues. Additionally, rapid advancements in materials and manufacturing techniques require engineers to stay updated and adapt designs efficiently, all while maintaining reliability and performance.

What are the key skills and qualifications needed to thrive as a propulsion system design engineer?

To thrive as a Propulsion System Design Engineer, you need a strong background in mechanical or aerospace engineering, advanced knowledge of thermodynamics, fluid dynamics, and materials science, usually supported by a relevant degree. Familiarity with CAD software, simulation tools (such as ANSYS or MATLAB), and industry standards is typically required. Strong problem-solving abilities, attention to detail, and effective teamwork and communication distinguish top performers in this field. These skills and qualities are vital for ensuring safe, innovative, and efficient propulsion system designs that meet rigorous technical and regulatory standards.

What does a propulsion system design engineer do?

A Propulsion System Design Engineer is responsible for designing, developing, and testing propulsion systems used in vehicles such as airplanes, rockets, or spacecraft. These engineers work on components like engines, turbines, and fuel systems to ensure they meet performance, safety, and efficiency standards. Their role often involves collaborating with multidisciplinary teams, conducting simulations, and overseeing prototype testing. They play a critical part in advancing technology and meeting regulatory requirements for propulsion systems.

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 Propulsion Department within VSD develops and evaluates cutting-edge propulsion technologies and systems for current and future government and commercial applications. The motto of the department is "We Deliver"; we deliver timely, objective, and actionable technical advice so that programs can execute efficiently toward mission success. The Solid Motors and Propulsion Technologies section is looking for a Propulsion Engineer (Member of Technical Staff- Propulsion Engineering). In this role, you will perform technical evaluations and assessments of propulsion systems for high-priority space missions. Your work may involve propulsion system development, manufacturing, test, and operations for multiple programs. You must have a strong technical foundation and be willing to learn a broad range of new technologies and systems and effectively communicate results and recommendations to inform critical decisions.

This position is located in El Segundo, CA., requiring at least 4 days onsite.

What You'll Be Doing

  • Developing and applying new and existing tools and analyses to assess the performance of space propulsion systems in ground test and flight

  • Identifying, assessing, and mitigating hardware and operational risks associated with components, systems, and interfaces

  • Providing real-time support for customer tests, flights, and anomaly resolution efforts

  • Participating in multidisciplinary teams including technical interchange meetings, hardware reviews, flight data reviews, and other activities to assess flight readiness of propulsion systems

  • Assisting with propulsion laboratory experimental efforts, including test execution, data analysis, and design upgrades

  • Preparing reports and presentations to communicate results and recommendations to Aerospace program offices, government personnel, and other customers

What You Need to be Successful

Minimum Requirements :

  • Master's degree from an accredited college/university program in Aerospace, Mechanical, Chemical, or Materials Science Engineering, Physics, or a related technical field

  • One year or more of applicable professional or academic experience

  • Knowledge of fundamental and advanced engineering principles in aerospace, mechanical, heat transfer, fluid dynamics, and thermodynamics as applied to the design, evaluation, and optimization of propulsion and propellant systems

  • Experience with the design, development, qualification, and acceptance requirements of propulsion systems: solid rocket motors, rocket engine, and/or hypersonic systems

  • Willingness to travel domestically and/or internationally approximately 20% of the time to support customer needs

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

How You Can Stand Out

It would be impressive if you have one or more of these:

  • Current secret-level clearance, or higher

  • PhD from an accredited program in a STEM discipline

  • Experience in one or more of the following: subsonic and/or supersonic combustion/reacting flows, turbomachinery, rotordynamics, rocket engine/motor testing, material properties, or propulsion system engineering

  • Hands-on experience with thermal-fluid and/or propulsion system testing or experimentation

  • Advanced proficiency with Python and/or MATLAB

  • Demonstrated ability to analyze high sample rate datasets using frequency and order domain techniques, including experience with spectral analysis tools and software
