What is the difference between Senior Propulsion Engineer vs Propulsion Engineer?

AspectSenior Propulsion EngineerPropulsion Engineer
Required CredentialsBachelor's or Master's in Mechanical, Aerospace, or Propulsion Engineering; 5+ years experienceBachelor's or Master's in related engineering fields; 2-4 years experience
Work EnvironmentDesign, testing, and development in aerospace or defense industriesDesign and testing of propulsion systems, often under supervision
Employer & Industry UsageMajor aerospace, defense, and space companiesSimilar industries, often as entry to mid-level roles

The main difference between a Senior Propulsion Engineer and a Propulsion Engineer lies in experience level, responsibilities, and expertise. Senior Propulsion Engineers typically lead projects, provide technical guidance, and have more extensive industry experience, while Propulsion Engineers focus on supporting design and testing tasks. Both roles are essential in aerospace and defense sectors, but the senior position requires more advanced skills and leadership capabilities.

What are some common challenges Senior Propulsion Engineers face when leading cross-functional teams on complex projects?

Senior Propulsion Engineers often encounter challenges in aligning diverse technical teams, balancing project timelines with rigorous testing standards, and integrating propulsion systems with other subsystems. Effective communication is crucial, as these engineers must translate technical requirements between engineering, manufacturing, and quality assurance groups. Additionally, they are responsible for mentoring junior engineers and ensuring that the team stays adaptable to evolving project priorities or unforeseen technical obstacles.

What are Senior Propulsion Engineers?

Senior Propulsion Engineers are experienced professionals who design, develop, and oversee the performance of propulsion systems, such as jet engines, rocket engines, or other mechanical systems that generate thrust for vehicles like aircraft, spacecraft, or missiles. They lead engineering teams, manage complex projects, and ensure that propulsion systems meet safety, efficiency, and performance standards. These engineers collaborate with multidisciplinary teams, troubleshoot technical issues, and often mentor junior engineers while staying updated on the latest advancements in propulsion technology.

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

To thrive as a Senior Propulsion Engineer, you need advanced knowledge of propulsion systems, fluid dynamics, thermodynamics, and a degree in aerospace or mechanical engineering, often supplemented by several years of industry experience. Familiarity with simulation software (such as ANSYS or MATLAB), CAD tools, and relevant certifications like Professional Engineer (PE) licensure is typically required. Strong problem-solving skills, leadership, and effective communication set outstanding engineers apart in this role. These skills and qualities are vital for driving innovative designs, ensuring safety and performance, and leading multidisciplinary teams in complex aerospace projects.

Job description

At Vast, our mission is to contribute to a future where billions of people are living and thriving in space. Vast is developing next-generation space stations to ensure a continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and unlocking a new space economy for government, corporate, and private customers. Using an incremental, hardware-rich and low-cost approach, Vast is rapidly developing its multi-module Haven Station. Haven Demo's 2025 success made Vast the only operational commercial space station company to fly and operate its own spacecraft. Next, Haven-1 is expected to become the world's first commercial space station when it launches, followed by additional Haven modules to enable permanent human presence by 2030. Our team is all-in, committed to executing our mission safely and on time. If you want to work with the most talented people on Earth furthering space exploration for humanity, come join us.
Vast is looking for a Propulsion Engineer, reporting to the Senior Manager, Haven-1 propulsion, to support the development of the systems that will be required for the design and build of artificial-gravity human-rated space stations.
This will be a full-time, exempt position located in our Long Beach location.
Responsibilities:
  • Collaborate closely with propulsion and systems design teams to provide manufacturing and assembly input for component hardware such as valves, regulators, tubing, ducting, manifolds, COPVs, fittings, and instrumentation used in propulsion and pressurization systems.
  • Develop, qualify, and optimize manufacturing processes and production equipment for propulsion components, with a focus on repeatability, quality, cost, and flight reliability.
  • Create and maintain detailed manufacturing plans, assembly procedures, travelers, and work instructions to support production of propulsion hardware across development, qualification, and flight builds.
  • Support propulsion systems including propellant feed, pressurization, venting, purge, and safety-critical fluid systems.
  • Identify and resolve manufacturing challenges through hands-on troubleshooting, root cause analysis, and implementation of corrective and preventive actions.
  • Work directly with suppliers to ensure timely delivery of high-quality propulsion components, including review and approval of supplier manufacturing processes and documentation.
  • Perform hands-on assembly, integration, and testing of propulsion components and sub-assemblies, ensuring compliance with engineering requirements and applicable aerospace standards.
  • Participate in design and manufacturing readiness reviews, providing actionable feedback to improve manufacturability, reliability, and scalability of propulsion hardware.
  • Partner with quality engineering to define inspection methods, acceptance criteria, and process controls for safety-critical fluid components.
  • Drive continuous improvement initiatives to reduce cycle time, improve yield, and increase robustness of propulsion manufacturing processes.
  • Stay current with propulsion manufacturing techniques, materials, joining methods, and industry best practices to inform design and production decisions.

Minimum Qualifications:
  • 3+ years of manufacturing engineering experience in aerospace, propulsion, or high-reliability fluid systems.
  • Experience with CAD tools (e.g., Siemens NX) and the ability to review designs, generate manufacturing documentation, and design assembly or test tooling.

Preferred Skills & Experience:
  • Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, Aerospace Engineering, or a related discipline.
  • Strong cross-functional communication skills and the ability to work effectively with propulsion, systems, test, and quality teams
  • High attention to detail and a strong ownership mindset for safety-critical hardware.
  • Strong GD&T knowledge and experience creating and reviewing engineering drawings.
  • Strong understanding of propulsion fluid systems, including tube fabrication, welding/brazing, cleaning, and assembly processes.
