Propulsion Engineer II (Miranda Engine) Verified today

About the Role

Join the Miranda propulsion engineering team designing, developing, and testing the first stage engine for Firefly's Eclipse vehicle. You will work across the full lifecycle of hardware, including requirements definition, design, analysis, development, test, and qualification. This role requires deep technical knowledge, extreme ownership, and clear communication with cross-functional teams. You will take primary responsibility for designing and releasing the integrated engine system, including complete fluids systems and secondary structures interfacing with engine and vehicle hardware.

Responsibilities

• Design and release Miranda fluids system designs interfacing with combustion devices, turbomachinery, valves, fluid systems, TVC, and avionics components.
• Own and execute development, qualification, and acceptance testing of engine systems and sub-systems.
• Coordinate with engineers, production, and Quality to produce and release engine sub-assembly and component drawings that maximize performance and reduce manufacturing complexity.
• Maintain multiple controlled revisions of engine CAD as component designs are traded in analysis and iterated in development testing.
• Provide hands-on support for development engine builds to iterate and improve design and layout.
• Develop and maintain engine interfaces; participate in test stand and vehicle installation procedures.
• Communicate risks and trade solutions to minimize failure risk in development, manufacturing, test, and flight.

Required Qualifications

• Bachelor's Degree in Mechanical Engineering, Aerospace Engineering, or equivalent.
• 5+ years experience with CAD and configuration management tools (Siemens NX and Teamcenter preferred).
• Experience working within large CAD assemblies.
• Familiarity with GD&T fundamentals, applications, and tolerance stackups.
• Strong background in mechanical design and metallic manufacturing techniques including subtractive and additive machining, welding, and inspection.
• Understanding of bipropellant liquid rocket fundamentals and ability to collaborate with subject matter experts to maximize engine performance.
• Knowledge of material selection for cryogenic, high pressure, and high temperature systems as well as Oxygen-compatible materials.
• Knowledge of fluid components such as valves, regulators, pressure transducers, tubing, pressurized hardware, seals, and instrumentation; experience performing fluid systems sizing analysis.
• History of developing solutions with partially defined requirements and changing criteria.

Desired Qualifications

• Advanced degree in Mechanical Engineering, Aerospace Engineering, or equivalent field.
• Experience with liquid rocket or space propulsion engines or systems.
• Experience in aerospace flight production programs.
• Knowledge of multi-disciplinary CAD modules and interfaces (pipe routing, electrical routing, sheet metal).
• Experience and interest in automating virtual workflows and tools.
• Experience reducing complexity of large integrated assemblies to reduce part count, cost, and lead time.
• Full hardware lifecycle ownership from blank sheet design to full operation.

Employment Terms

U.S. citizenship, lawful permanent resident status, or eligible authorization from the U.S. Department of State required to comply with ITAR regulations.
