## Description

You will be a key contributor to turning propulsion architecture into manufacturable, testable, and flight-ready hardware across the engine, fuel, oil, and bleed air systems.

This role is hands-on, detail-oriented, and highly cross-functional - requiring close collaboration with propulsion REs, technicians, machinists, production, controls, airframe, and flight test teams.

### Responsibilities:

- Own the design and release of propulsion hardware supporting the engine, fuel, oil, and bleed air systems.

- Develop and maintain CAD models, drawings, and assemblies using Siemens NX with proper GD&T.

- Translate propulsion architecture and requirements into hardware that is manufacturable, testable, and robust in flight.

- Work directly with the machine shop, production, and technicians to support builds, resolve non-conformances, and drive iterative improvements.

- Support test campaigns by providing hardware design support, instrumentation accommodation, and rapid iteration based on test findings.

- Apply engineering judgment and analysis (e.g., hand calcs, ANSYS, FEA, GFSSP, 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 efforts, and root cause investigations related to propulsion hardware.

### Requirements:

- Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or a related engineering discipline.

- 5+ years of experience in aerospace hardware design, preferably supporting propulsion systems.

- Proficiency in CAD modeling and drawing creation (NX preferred) with sound application of GD&T.

- Experience working directly with production, technicians, and machine shops to resolve real-world build issues.

- Understanding of design for manufacturing, including machining limitations, tolerance stack-ups, and assembly workflows.

- Some hands-on experience developing assembly guidance and supporting hardware builds and test integration.

- U.S. Citizenship or ability to comply with ITAR requirements.

### Preferences:

- Experience with jet propulsion systems on UAVs or tactical aircraft.

- Familiarity with GFSSP, REFPROP, ANSYS, or FEA to support design trade studies and validation.

- Ability to write Python scripts for design automation, analysis, or data processing.

- Experience with interface control, fastener selection for high-vibration environments, and high-temperature materials.

- Experience designing hardware in test-driven development environments with rapid iteration cycles.

- M.S. in Aerospace Engineering or a related discipline.
