Who We Are:
The Liquid Propulsion Team performs R&D to solve challenges and advance technology in liquid propulsion systems. We perform design, analysis, testing, and hardware delivery for launch, landing, lunar, and orbital vehicles. We do component design (PMDs/LADs, vortex breakers, tank baffles, etc.) and system level design, procurement, AI&T, and delivery. Our range of applications cover ground equipment to vehicles, high-g to 0-g, and supercritical to cryogenic conditions.

- Design, analysis, procurement, AI&T, performance testing, delivery and in-service operation tasks will be included.
- Perform design and analysis tasks for fluid, thermal, and machinery projects using engineering software, self-created analytical toolsets, and existing knowledge from engineering standards, technical literature, and industry techniques
- Perform experimental testing and support for both component-level and system-level testing of propulsion, energy, and combustion machinery.
- Perform engineering and scientific research and investigations to support projects and advance the state-of-the-art.
- Interpret and present findings and results to project team and clients in a concise and clear way.
- Provide support to more than one project in a flexible and diverse team environment.
- Have and demonstrate a firm grasp of engineering and scientific disciplines and applied first principles.
- Learn new technical skills to complete project work.
Requirements:
- Requires a Bachelors degree in Mechanical Engineering, Aerospace Engineering, or related engineering degree.
- 5 years: Conducting propulsion system design, analysis, assembly, integration and testing of flight hardware programs. Participation in the entire life cycle: concept, design, procurement, assembly and testing. Experience in execution and management of tasks/phases/programs is desired.
- 5 years: Conducting fluid and thermal system analyses using commercial or custom software, such as flow network, computational fluid dynamics, or mechanical analysis solvers. Firm understanding of the underlying physics of fluid dynamics, thermodynamics, aerodynamics, or heat transfer.
- 2 years: Experimental test experience of propulsion and other fluid and thermal systems; including, designing, building, commissioning, operating, and analyzing data. Also familiar with common flight launch and range safety requirements and acceptance/qualification procedures.
- Desired experience, but not required: engineering MS or PhD degrees; range safety; cryogenics; microgravity fluids; GNC familiarity; mechanical design and fabrication; computational programing/scripting; LabVIEW, PID control and data acquisition; SolidWorks; ANSYS products.
- A valid/clear driver's license is required.
Special Requirements:
Must be a U.S. person (i.e., U.S. citizen, non-U.S. citizen national, lawful permanent resident, asylee, or refugee) due to ITAR work in section.
An Equal Employment Opportunity Employer: race, color, religion, sex, national origin, disability, and veteran status.

Mid Level Propulsion Engineer Jobs: Frequently Asked Questions
How do I get a mid level propulsion engineer job?
Position your existing experience around ownership and impact, not just task completion. Highlight propulsion systems you have designed, tested, or iterated on from concept through delivery, and emphasize decisions you made with limited oversight. Recruiters at this level want evidence that you can lead a subsystem or project thread independently, so tailor each application to show that specifically rather than listing responsibilities generically.
Which companies hire mid level propulsion engineers?
Companies hiring mid level propulsion engineers right now include BNH, Amazon, and Blue Origin, based on current listings on Migrate Mate as of September 2026. Hiring at this level comes from a mix of established aerospace and defense contractors, commercial space launch companies, and advanced mobility firms investing in next-generation propulsion programs.
Are there remote mid level propulsion engineer jobs?
Yes, though most propulsion roles require some on-site or lab access given the hands-on nature of the work. About 33% of mid level propulsion engineer openings are remote or hybrid as of September 2026, concentrated in areas like systems analysis, simulation, and program coordination where physical test access is less critical day to day.
How do I move up to a mid level propulsion engineer role?
The path from entry level to mid level is built on progressively owning larger pieces of work. Start by going deep on one propulsion discipline, whether combustion, thermodynamics, or fluid systems, then seek out projects where you lead a design loop or own a test campaign end to end. Documenting measurable outcomes, such as performance improvements or schedule contributions, gives you the concrete evidence mid level roles require.
Which industries hire the most mid level propulsion engineers?
Mid Level propulsion engineer roles concentrate in Aerospace & Defense, Retail, and Automotive, based on current listings on Migrate Mate as of September 2026. These sectors drive hiring because they are actively developing or scaling propulsion systems, from orbital launch vehicles and hypersonic platforms to electric aviation and advanced defense applications, all of which need engineers ready to take on meaningful technical ownership.
