• Design and layout of storable propellant rocket engine combustion devices.
• Define and conduct trade studies to design combustion chambers for engines by balancing thermal restrictions and performance requirements by implementing the right cooling methods.
• Work with supplier(s) to identify the appropriate valves for propellant control based on hypergol compatibility and performance requirements like response times, cycle frequency, etc.
• Perform system-level trade studies, modeling, and simulation to optimize performance, efficiency, and reliability. Performance modeling can include use of TDK or similar industry standard tools.
• Own hypergolic propulsion hardware from concept, detailed design, analysis, prototyping, testing, and production support.
• Collaborate cross-functionally with structures, thermal, manufacturing, and test teams.
• Develop and review engineering documentation, including requirements, specifications, and design reviews.
• Lead root cause analysis and implement corrective actions for design and test issues.
• Support test campaigns, including planning, execution, data analysis, and reporting.
• Prepare formal presentations and reports for customer communication and gated product development reviews (SRR, PDR, CDR, etc.)
• Ensure compliance with industry standards, safety regulations, and quality requirements.
• Provide technical mentorship and guidance to junior engineers.
• Contribute to long-term technology roadmaps and innovation initiatives.
• Utilize SolidWorks CAD for design of components and/or assemblies.

Requirements

• M.S. or higher degree in related engineering or technical field. Equivalent professional experience will be considered in lieu of a degree.
