Job Description:
Shield AI is seeking a Senior Propulsion Design Engineer to design and deliver hardware supporting the propulsion system of a low-bypass turbofan-powered UAV. You’ll work across the engine, fuel, oil, and bleed air systems—helping transform conceptual propulsion architecture into testable, manufacturable, and flight-ready hardware.

This is a hands-on, high-ownership role for an engineer who thrives on building complex systems in a fast-paced environment. You’ll collaborate across disciplines to ensure performance, reliability, and manufacturability of next-generation aircraft propulsion systems.

What you will do in this role:
Design propulsion components and subsystems from concept through production release.
Create detailed CAD models, drawings, and assemblies in Siemens NX with full GD&T application.
Collaborate with technicians, machinists, and production teams to solve real-time design and build challenges.
Support prototype builds, troubleshoot non-conformances, and drive iterative hardware improvements.
Apply sound engineering judgment and analysis to validate design decisions (e.g., hand calcs, FEA, or thermal analysis).
Participate in cross-functional design reviews and help define interface requirements across propulsion, structures, and systems teams.
Author design documentation, assembly instructions, and release packages for production readiness.
Contribute to continuous improvement of design standards and workflows across the engineering team.
Required qualifications:
B.S. in Mechanical, Aerospace, or related engineering discipline.
3–5+ years of mechanical design experience in aerospace or related high-performance industries.
Strong proficiency in CAD modeling and drawing creation (NX preferred) and GD&T.
Working knowledge of design-for-manufacturing, machining, tolerances, and assembly workflows.
Demonstrated ability to collaborate across engineering and production teams to resolve design and build issues.
U.S. Citizenship or ability to comply with ITAR requirements.
Preferred qualifications:
Experience with propulsion systems (fuel, oil, bleed air) or engine hardware.
Familiarity with GFSSP, REFPROP, ANSYS, or FEA tools for design validation.
Exposure to high-temperature materials and thermally stressed component design.
Experience developing work instructions, assembly documentation, and build guidance.
Master’s degree in Mechanical or Aerospace Engineering a plus.
