Senior Propulsion Design Engineer
Shield AI
What you will do in this role:
- Support the design of propulsion components and subsystems from concept through production release.
- Create and maintain CAD models, detailed drawings, and assemblies using Siemens NX with applied GD&T.
- Contribute to the development and application of propulsion design standards and team best practices.
- Work closely with production, machine shop, and technician teams to support builds and resolve non-conformances.
- Assist in developing work instructions, assembly guidance, and documentation for repeatable hardware builds.
- Design with a strong awareness of manufacturability, machining limitations, and material and tolerance constraints.
- Apply basic engineering analysis and judgment (e.g., hand calcs, ANSYS, FEA, GFSSP, REFPROP) to support sizing and design validation.
- Support configuration control, BOM structure, and change processes within Teamcenter or an equivalent PLM.
- Participate in design reviews, interface discussions, and problem-solving efforts during hardware development.
Required qualifications:
- Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related engineering discipline.
- 5+ years of experience in aerospace mechanical design, preferably with propulsion hardware.
- Proficiency in CAD modeling and drawing creation (NX preferred) and sound application of GD&T.
- Ability to work effectively with production, technicians, and machine shop teams to resolve design and build issues.
- Understanding of design for manufacturing, including stack-up analysis, surface modeling, and fabrication constraints.
- Some hands-on experience developing or supporting assembly instructions and resolving build issues.
- Familiarity with configuration management and PLM systems such as Teamcenter.
- U.S. Citizenship or ability to comply with ITAR requirements.
Preferred qualifications:
- Experience with GFSSP, REFPROP, ANSYS, FEA, or similar tools for analysis and validation.
- Ability to write Python scripts for design automation, simulation, or data processing.
- Proficiency in tolerance stack-up analysis and interface control for complex assemblies.
- Knowledge of fastening methods and design for vibration environments.
- Familiarity with high-temperature materials and thermally constrained mechanical systems.
- Experience designing for internal combustion, turbine, or rocket propulsion systems, particularly in development or test settings.
- M.S. in Mechanical Engineering, Aerospace Engineering, or a related discipline.
