  • Design, model, and document mechanical components, sub-assemblies, and major end items in accordance with rigorous defense system requirements.
  • Generate and maintain parametric 3D CAD models, complex assembly hierarchies, and detailed 2D engineering drawings.
  • Validate design fit, form, and functionality through rapid prototyping, physical testing, and engineering simulations.
  • Support factory operations, integration facilities, and external suppliers with product manufacturing, assembly, and integration.
  • Participate actively in design peer reviews, resolve technical action items, and conduct trade studies to inform engineering decisions.
  • Collaborate with multi-disciplinary engineering teams to analyze and resolve mechanical hardware issues.


Qualifications You Must Have

  • Masters degree in Science, Technology, Engineering, or Mathematics (STEM) discipline. Degree must be obtained by start date.
  • Experience utilizing parametric 3D CAD software (such as SolidWorks, PTC Creo, Autodesk Inventor, CATIA, or Siemens NX) to generate 3D solid models, mechanical assemblies, and detailed 2D engineering drawings.
  • Experience in mechanical design applied through coursework, academic research, engineering competition teams (e.g., Formula SAE, Baja, Robotics), or hands-on projects.
  • Experience may be obtained through on-the-job experience, research, coursework, or projects.


Qualifications We Prefer

  • Master's degree in Mechanical Engineering or Aerospace Engineering.
  • Cumulative GPA of 3.0 or higher from an ABET-accredited institution.
  • Knowledge or application of Geometric Dimensioning & Tolerancing (GD&T) principles per ASME/ANSI Y14.5.
  • Hands-on experience in rapid prototyping and mechanical fabrication, including additive manufacturing (3D printing via FDM, SLA, or SLS) or machine shop equipment (mills, lathes, drill presses, or CNC equipment).
  • Demonstrated problem-solving aptitude applied to structural, thermal, or multi-disciplinary hardware challenges.


What We Offer:

  • Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world. At RTX we value: Safety, Trust, Respect, Accountability, Collaboration, and Innovation.
