POWERTECH is a center of excellence for propulsion technologies, specializing in the design, engineering, and manufacturing of combustion engines, expendable turbojet engines, and turbofan engines for aerospace, defense, and autonomous applications, including UAV platforms.

The Mechanical Engineer II is responsible for supporting the design, analysis, and development of gas turbine and turbojet/Turbofan engines. The role focuses on executing detailed mechanical design tasks, supporting analysis and testing, and contributing to product development under the guidance of senior engineers, while taking ownership of defined components or subassemblies.

• Design and develop turbo machinery components, including:
• Shafts, spacers, and structural parts
• Casings, brackets, and housings
• Seals and secondary hardware
• Create 3D CAD models and 2D engineering drawings
• Apply GD&T and tolerance stack-up principles

• Perform high fidelity:
• Stress and deformation analysis of engine components
• Fatigue assessments (LCF/HCF with guidance)
• Support thermal growth and clearance evaluations

• Assist in rotor assembly design and stack-up definition
• Support bearing integration and housing design

• Apply Design for Manufacturability (DFM) principles
• Interaction with manufacturing people
• Define basic material selections and tolerances

• Support engine build and rig testing activities

• Prepare engineering drawings and documentation
• Support design changes and configuration updates
• Support root cause analysis (RCA) for failures
• Contribute to design improvements and lessons learned

• Bachelor’s degree in Mechanical or Aerospace Engineering
• 4–7 years of experience in mechanical design (turbo machinery preferred)

• Good understanding of:
• Stress and fatigue behavior
• Basic rotating machinery concepts
• Proficiency in:
• CAD tools (CATIA, NX, or similar)
• Basic FEA tools (ANSYS or similar)

• Experience in gas turbines or turbojet engines
• Exposure to:
• Bearings and lubrication systems
• Sealing and clearance control
• Experience supporting testing or prototype builds
