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

To thrive as a Propulsion System Engineer, you need a solid background in mechanical or aerospace engineering, with strong analytical and problem-solving skills supported by a relevant degree. Familiarity with CAD software, simulation tools like ANSYS or MATLAB, and knowledge of propulsion system regulations or certifications (such as those from SAE or FAA) are typically required. Strong teamwork, communication, and project management abilities set outstanding engineers apart in collaborative and high-stakes environments. These skills ensure the safe, efficient, and innovative design and operation of propulsion systems in complex aerospace projects.

What are some common challenges faced by Propulsion System Engineers, and how can they be addressed?

Propulsion System Engineers often encounter challenges related to integrating complex mechanical, electrical, and software components while ensuring safety, reliability, and efficiency. These challenges can be addressed by collaborating closely with cross-functional teams, conducting rigorous simulation and testing, and staying current with industry standards and technological advancements. Clear communication and adaptability are key, as project requirements and technologies may evolve rapidly. Additionally, effective troubleshooting and problem-solving skills are essential for addressing unexpected issues during development and testing phases.

What is the difference between Propulsion System Engineer vs Mechanical Engineer?

AspectPropulsion System EngineerMechanical Engineer
Required CredentialsBachelor's or Master's in Aerospace, Mechanical, or Propulsion EngineeringBachelor's or Master's in Mechanical Engineering or related field
Work EnvironmentDesign, develop, and test propulsion systems for aerospace or automotive industriesDesign, analyze, and manufacture mechanical systems across various industries
Industry UsagePrimarily aerospace, defense, and space sectorsBroadly used in automotive, manufacturing, energy, and aerospace sectors

The Propulsion System Engineer specializes in designing and testing propulsion components, often within aerospace and defense industries, requiring specific knowledge of propulsion systems. Mechanical Engineers have a broader focus on mechanical systems across multiple industries. While both roles require strong engineering fundamentals, Propulsion System Engineers focus more on propulsion-specific design and testing, whereas Mechanical Engineers work on a wider range of mechanical systems.

What are Propulsion System Engineers?

Propulsion System Engineers are professionals who design, develop, test, and maintain systems that propel vehicles, such as rockets, airplanes, or spacecraft. They work with various types of engines, including jet, rocket, and other advanced propulsion technologies, to ensure efficient and safe performance. Their responsibilities often include analyzing system requirements, troubleshooting issues, and collaborating with multidisciplinary teams to optimize propulsion systems for specific missions or vehicles. They play a crucial role in the aerospace, automotive, and defense industries.

Job description

Founded in 2015, Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems. Its products include Hivemind autonomy software and V-BAT and X-BAT aircraft. With offices and facilities across the U.S., Europe, the Middle East, and Asia-Pacific, Shield AI’s technology actively supports operations worldwide. For more information, visit www.shield.ai. Follow Shield AI on LinkedIn, X, Instagram, and YouTube. 

Job Description:
Shield AI is seeking a highly experienced Propulsion Test Engineer to lead propulsion test planning and execution for X-BAT, the world’s first autonomous VTOL jet aircraft. In this role, you will shape the propulsion test strategy, direct complex engine and hover test campaigns, and provide technical leadership across the program to ensure safe and rapid development of a next-generation autonomous aircraft. 
 
The ideal candidate brings deep expertise in jet propulsion testing, developmental flight test operations, to include mission control room operations, and high-energy ground testing. You will work closely with propulsion engineers, flight test teams, autonomy developers, instrumentation specialists, and safety organizations to define test objectives, assess risk, and deliver the data required to advance the aircraft through its test envelope. 
 
This is a high-impact role for a technical leader who thrives in fast-paced, experimental environments and who wants to help define the future of autonomous aviation. 
What you'll do:
  • Support engine, hover, static, and integrated propulsion test campaigns for X-BAT including planning, execution, and post-test analysis. 
  • Advise on propulsion system readiness and define test objectives, test point development, build up approach, success criteria, and instrumentation requirements. 
  • Develop and review test procedures, hazard analyses, run cards, and safety documentation for high-energy test operations. 
  • Provide technical oversight during engine runs, hover tests, transition testing, and propulsion-autonomy integration events. 
  • Serve as a propulsion subject-matter expert during Test Readiness Reviews (TRRs), Test Hazard Analyses (THAs), and Operational Risk Management (ORM) assessments 
  • Support root-cause investigations related to propulsion performance, engine controls, thermal behavior, vibration, and integration issues. 
  • Partner with Autonomy and Avionics teams to evaluate propulsion-related interactions such as thrust control logic, response lags, fail-safes, and emergency behaviors. 
  • Collaborate with Instrumentation Engineering to ensure data quality, test post process analysis, reporting, timing, and fidelity across propulsion channels. 
  • Support field deployments, remote test sites, and intensive test cycles as required to meet program schedules. 
Required qualifications:
  • Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or related technical discipline. 
  • 8+ years of experience in propulsion testing for jet engines, VTOL systems, unmanned aircraft, or developmental flight test programs. 
  • Demonstrated expertise executing and analyzing engine tests, hover/transition events, and integrated propulsion-airframe testing. 
  • Strong understanding of engine controls, FADEC systems, thrust measurement, thermal analysis, and vibration/loads behavior. 
  • Experience writing and reviewing high-energy test procedures, readiness documentation, and hazard analyses. 
  • Proven ability to operate safely and decisively in fast-paced test environments. 
  • Excellent communication skills and demonstrated performance in multidisciplinary engineering organizations. 
  • Ability to travel and support extended field test deployments. 
Preferred qualifications:
  • Master’s degree or higher in Aerospace or Mechanical Engineering. 
  • Experience with tail-sitter, VTOL, or thrust-vectoring propulsion systems. 
  • Background in autonomy-powered aircraft, propulsion-system modeling, or propulsion-flight-control integration. 
  • Familiarity with IRIG, PCM, instrumentation requirements, and high-rate telemetry data. 
  • Experience supporting complex investigations or leading propulsion technical review boards. 
  • Prior involvement in developmental or experimental flight test programs. 
  • Experience with compressed-air starts, engine-health monitoring systems, or high-temperature structural analysis.
