The role

You will own the design, analysis, development and qualification of combustion equipment for liquid rocket engines. This includes gas generators, pre burners, injector heads, combustion chambers, and ignition systems.

What you will do

• Own the design and development of liquid rocket engine combustion equipment.
• Define component requirements, operating envelopes, interface conditions and technical budgets.
• Perform preliminary and detailed sizing of combustion devices.
• Lead architecture and design trade offs.
• Plan, support and evaluate component and engine level test campaigns.
• Investigate combustion anomalies and performance deviations.
• Own the technical development roadmap for hardware.
• Work closely with various propulsion and manufacturing teams to deliver an integrated propulsion system.

Required qualifications

• MSc in aerospace engineering, mechanical engineering or a comparable technical discipline, or equivalent professional experience.
• Several years in liquid rocket engine development, with significant responsibility for combustion device design, analysis, development or testing.
• Hands on experience with gas generators, pre burners or comparable high performance liquid propellant combustion devices.
• Excellent understanding of combustion, thermodynamics, fluid dynamics, heat transfer and liquid rocket propulsion.
• Significant experience in injector or combustor sizing, particularly at very high or very low O/F, and in interpreting hot fire test data.
• Experience owning a development roadmap through design reviews and into qualification.
• Proficiency in Python, MATLAB or a comparable programming language.
• Strong technical ownership and the ability to make sound engineering decisions with incomplete early phase data.
• Fluent in English.
• Willingness to travel occasionally for test and launch operations.

Nice to have

• Experience with both gas generators and pre burners across different liquid rocket engine architectures.
• Experience with combustion stability, acoustic analysis, ignition transients or operability assessment.
• Experience with injector technologies such as coaxial, impinging, swirl or pintle concepts.
• Experience taking combustion hardware from initial sizing through manufacturing and hot fire qualification.

Benefits
