Description

Agile is seeking an experienced Staff Propulsion Design Engineer who will lead the design, development, and optimization of propulsion components and systems. This role requires deep technical expertise, cross-functional leadership, and the ability to drive Agile's propulsion devices from concept through production. The ideal candidate for this role will also be able to interpret hot-fire test data and drive design modification as well as provide technical guidance to junior engineers on sound design practices. Agile follows a fast-paced culture and the ideal candidate will have the opportunity for growth and increased sphere of influence as a technical leader. Critical skillsets being sought after are expertise in heat transfer, fluid dynamics, rocket propulsion, spacecraft system architecture.

Responsibilities:
  • Lead the design and development of hypergolic propulsion systems and components, including combustion devices, liquid rocket engines, propellant systems, and supporting components.
  • Establish architecture and design injectors for engines based on operational requirements including pulse mode, steady state or throttle operations and performance needs.
  • 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.
  • 12+ Years of experience working on development of propulsion systems. Strong background in fluid dynamics, thermodynamics, heat transfer, and combustion.
  • Deep understanding of fuel film cooling and regenerative cooling in bipropellant engines as well as design experience to ensure thermal stability in engines.
  • Experience working with performance modeling tools like TDK or similar JANNAF compliant tools commonly used in the storable propulsion industry.
  • Working knowledge of and experience with selection of valves for different chemical propulsion applications.
  • Multi-disciplined engineer confident working through ambiguity and uncertainty across complex assignments.
  • Proven track record of delivering hypergolic propulsion systems from concept to production
  • Experience with propulsion testing and data analysis, specifically liquid propulsion.

Preferred Qualifications:
  • Experience with chemical rocket propulsion systems.
