About the Job

Requirements

  • A bachelor's degree and at least 9 years of prior relevant experience, or a graduate degree and at least 7 years of prior related experience; alternatively, at least 13 years of prior related experience in lieu of a degree.
  • Must be able to obtain a U.S. security clearance.

Responsibilities

  • Develop concepts for mechanical systems to meet customer propulsion requirements. Perform preliminary design, component sizing, and propulsion hardware packaging to meet volume and mass constraints. Develop mechanical solutions needed to integrate propulsion systems with vehicle and payload interfaces.
  • Create mechanical components and higher-level systems for high-pressure and extreme-environment applications. Interpret engineering models and drawings and perform tolerance studies. Evaluate technical input from hardware suppliers and work with cross-functional teams on producibility improvements and cost savings. Participate in trade studies and preliminary designs using Creo 3D computer-aided design software.
  • Prepare engineering drawings with associated geometric dimensioning and tolerancing in accordance with ASME Y14.5 standards. Participate in team meetings to assure design content for new or modified engineering designs. Release drawings through the Windchill product lifecycle management system. May lead the work of design staff or oversee the work of product-definition designers.
  • Prepare and deliver technical presentations for internal and external customers. Prepare engineering reports to support tolerance studies, engineering analyses, failure investigations, and technical close-out reports. May attend engineering review boards to support program-level technical decision-making.
  • Participate in development and qualification testing for new product development. Create test integration hardware to support flow testing, vibration testing, and hot-fire testing. May support hands-on work during test preparation and participate in data reduction.
  • Perform or coordinate thermal and/or structural analysis to predict component- and system-level performance in product design.
  • Coordinate with manufacturing and quality engineering to ensure hardware is producible and inspectable.

Desired Qualifications

  • Experience in the design, development, and/or production of mechanical systems for the aerospace and/or defense industries.
  • Experience with liquid and gaseous pressurized systems and components such as tanks, fluid routing, sealing devices, valves, and regulators.
  • Knowledge of liquid-fueled propulsion systems.
  • Understanding of additive manufacturing and/or traditional manufacturing processes such as machining, welding, brazing, and heat treating.
  • Working knowledge of ASME Y14.5.
  • Experience with CAD software tools such as Creo and PLM systems such as Windchill.
