As an Engine Assembly Responsible Engineer you will be responsible for owning top-level engine CAD models. Depending on the phase of the program and the engine configuration that you are owning, this role will entail: Lead CAD release and configuration control for production engine assemblies, ensuring accurate eBOM structures and smooth downstream integration Own engine layout and packaging trades, including definition of Keep-in-Zone (KiZ) and Keep-out-Zone (KoZ) boundaries Design and analyze Integrated Design hardware (fluid manifolds, tubing, ducting, secondary structures) and execute rapid design tweaks to support engine testing Drive cross-functional alignment as point of contact for Vehicle, Avionics, Manufacturing, Integration, and Test teams Define engine assembly tolerances/requirements as defined on Interface Control Diagrams (ICDs.) - Establish and standardize best practices across the Propulsion organization for things like fittings, bolts, seals, etc. Champion the change management process and help continuously improve it. - Own tracking of key engine metrics, like mass and part count Partner with the Integration/Manufacturing team by reviewing and continuously improving Process Plans, Work Orders, and Non-Conformances Strive to set downstream stakeholders up for success by enabling increased engine build rates and quality. Provide floor support at times to resolve build issues

  • Lead CAD release and configuration control for production engine assemblies, ensuring accurate eBOM structures and smooth downstream integration
  • Own engine layout and packaging trades, including definition of Keep-in-Zone (KiZ) and Keep-out-Zone (KoZ) boundaries
  • Design and analyze Integrated Design hardware (fluid manifolds, tubing, ducting, secondary structures) and execute rapid design tweaks to support engine testing
  • Drive cross-functional alignment as point of contact for Vehicle, Avionics, Manufacturing, Integration, and Test teams
  • Define engine assembly tolerances/requirements as defined on Interface Control Diagrams (ICDs.)
  • Establish and standardize best practices across the Propulsion organization for things like fittings, bolts, seals, etc.
  • Champion the change management process and help continuously improve it.
  • Own tracking of key engine metrics, like mass and part count
  • Partner with the Integration/Manufacturing team by reviewing and continuously improving Process Plans, Work Orders, and Non-Conformances
  • Strive to set downstream stakeholders up for success by enabling increased engine build rates and quality.
  • Provide floor support at times to resolve build issues
  • 8+ years of professional design experience
  • Bachelor's degree in an engineering field
  • Demonstrated project/technical leadership skills
  • Strong understanding of engineering fundamentals in structures, fluids, thermal, and mechanisms
  • CAD skills (any platform) and ability to make high quality engineering drawings that meet industry standards and leverage GD&T as needed
  • Experience with large CAD model management, change management, and configuration management
  • Experience owning ambiguous layout and packaging trades. Demonstrated ability navigating conflicting stakeholder requirements and finding the best path forward
  • Experience designing Integrated Design hardware (manifolds, secondary structure, tubing, etc.)
  • Systems thinker. Demonstrated ability to zoom out and view the engine's design holistically. Desire to do what is best for the engine as a whole, rather than a specific component
  • Ability to understand the work of other teams and assess how that work will impact the engine as a whole/impact other teams or components. Proactively communicates these assessments as needed
  • Attention to detail, thorough, exhibits strong follow-through. Understands the critical importance of a flawless eBOM that sets downstream stakeholders up for success
  • Great Integration/Manufacturing partner. Experience with any Manufacturing Execution System (MES.) Addresses DFA/DFM feedback in a timely fashion to set production up for success
  • Experience with Siemens NX and Teamcenter, specifically
  • Experience in the design of liquid propulsion components and systems
  • Experience with Finite Element Analysis (FEA) and commercial tools such as Ansys, Abaqus, or Nastran
  • Familiarity with aerospace standards (AS, NAS, SAE, etc.)
  • Experience with creating release, mass, and part count reports. Ability to communicate this information to leadership and stakeholders in a clear and concise manner
  • Familiarity with Qualification and Acceptance test requirements for flight hardware
