Are you ready to explore the world of aerospace and defense? Do you want to learn from and collaborate with some of the greatest minds in the industry? At RTX, our internships, co-ops and full-time careers provide an exceptional foundation to work on complex problems, advance your skills and create a safer, more connected world. Discover opportunities to make a difference at RTX.

What You Will Do

Immerse yourself in a full-time, Monday-Friday co-op session, that will run May/June- December (including the Fall semester; it is expected students will take a semester off from coursework to fully engage with this working mentorship opportunity).

As a Mechanical Design Engineering Co-op in the Mechanical Controls product line at Collins Aerospace, you will participate on a team to evaluate customer and subsystem hydraulic and/or pneumatic component requirements to generate compliant hardware designs for airframe and engine systems. Parts are designed to operate in fluid environments (fuel, oil, air), and function under challenging operating conditions. Designs are done by generating physics-based performance models (1D) and verified using CFD. Designs are also analyzed structurally using FEA. Candidate will work within an integrated team that includes Project Engineering, Dynamic Engineering, Systems Engineering, Drafting, and Structures.

Qualifications You Must Have

• Must be pursuing a Bachelor's or Advanced degree in Mechanical Engineering, Aerospace Engineering, or related Science, Technology, Engineering or Mathematics (STEM) major and actively enrolled through the completion of the internship/co-op session.
• Must have a minimum of 45 hours of credit by the start of the internship / co-op session.

Experience may be obtained through on-the-job experience, research, coursework, or projects.

Qualifications We Prefer

• Experience with 2D and 3D Computer Aided Design (CAD) software such as UG NX, Catia, SolidWorks, AutoCAD, Autodesk or equivalent
• Experience in CFD tools such as StarCCM+ and/or in FEA tools such as ANSYS, ABAQUS, or equivalent
• Experience with additive manufacturing
• Experience with Microsoft Office Suite (Excel, Word, PowerPoint, and/or Outlook)
• Prior RTX internship, co-op, or work experience

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.

Relocation Eligibility

Hybrid: Employees who are working in Hybrid roles will work regularly both onsite and offsite. Ratio of time working onsite will be determined in partnership with your leader.
