Staff Propulsion Design Engineer (Dallas)
Shield AI
What you will do in this role:
- Own the design of propulsion components and subsystems from concept through production release
- Develop and maintain high-quality CAD models, detailed drawings, and assemblies using Siemens NX with fully applied GD&T
- Write and enforce propulsion design standards and contribute to company-wide design best practices
- Collaborate closely with the machine shop, production team, and technicians to support builds, resolve non-conformances, and drive iterative improvements
- Develop initial work instructions, assembly guidance, and design documentation for repeatability and scalability
- Ensure designs are practical, manufacturable, and cost-effective, with strong understanding of machining, tolerances, materials, and assembly workflows
- Apply engineering analysis and judgment (e.g., hand calcs, GFSSP, ANSYS, FEA, REFPROP) to support sizing, load cases, and design validation
- Support configuration management, BOM control, and change processes using Teamcenter or equivalent PLM
- Participate in design reviews, interface control working groups, and root cause investigations
Required qualifications:
- Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related engineering discipline
- 7+ years of experience in mechanical design for aerospace, with direct propulsion hardware experience preferred
- Expert-level proficiency in CAD modeling and drawing creation (NX preferred) and application of GD&T
- Proven ability to work cross-functionally with production, machine shop personnel, and technicians to solve real-time hardware issues
- Familiarity with design for manufacturing, including machining processes, surface modeling, stack-up analysis, and fabrication limitations
- Hands-on experience developing assembly work instructions, troubleshooting build issues, and implementing hardware-driven design changes
- Experience with configuration management, PLM systems (Teamcenter), and BOM structure
- U.S. Citizenship or ability to comply with ITAR requirements
Preferred qualifications:
- Experience with GFSSP, REFPROP, ANSYS, FEA, or other mechanical and thermal analysis tools
- Ability to write Python scripts for design automation, data analysis, or simulation support
- Proficient in interface control and tolerance stack-up analysis for complex assemblies
- Knowledge of fastening methods and joint design for high-vibration, aerospace environments
- Familiarity with high-temperature materials and design practices for thermally stressed components
- Prior experience designing hardware for internal combustion, turbine, or rocket propulsion systems, particularly in development or test environments
- M.S. or Ph.D. in Mechanical Engineering, Aerospace Engineering, or a related engineering discipline
