Mechanical Engineer Intern (Summer 2027)

RTX•El Segundo, CA

22h•$42,000 - $88,000•Onsite

About The Position

Raytheon Intelligence & Space is seeking a Mechanical Engineer Intern to support development, integration, and testing across space and airborne programs in the space and airborne optics department in El Segundo, California. The intern will perform mechanical component design for opto-mechanical systems using Creo and support assembly, integration, and test work in a laboratory environment. They will work with junior and senior manufacturing and mechanical engineers on the design, build, and test of electro-optical/infrared (EO/IR) space hardware. The role includes creating and revising opto-mechanical designs and drawings, generating assembly instructions, and providing build support alongside technicians and engineers from other disciplines. The intern will apply design-for-producibility and manufacturability principles, research component designs and materials, and produce detailed drawings incorporating GD&T. Work involves collaboration across engineering and analysis teams on material selection, thermal management, precision mechanical mounting and motion, and structural optimization while balancing schedule constraints. The intern will also participate in peer reviews and use a product data management tool to create, revise, and process engineering changes. This is an onsite internship. U.S. citizenship is required, along with the ability to obtain and maintain a U.S. government security clearance; an active and existing DoD Top Secret clearance is required after the first day. Applicants must be actively enrolled in a bachelor’s or advanced degree program through the internship and have at least 60 credit hours by its start.

Requirements

Must be pursuing a bachelor’s or advanced degree in Mechanical Engineering or a related STEM major and remain actively enrolled through the internship/co-op session.
Must have at least 60 credit hours by the start of the internship/co-op session.
Experience in the design and development of mechanical hardware.
Experience with commercial CAD software, such as Creo.
Experience may be obtained through on-the-job experience, research, coursework, or projects.
U.S. citizenship is required because the role requires eligibility for a U.S. government security clearance.
Ability to obtain and maintain a U.S. government security clearance; an active and existing DoD Top Secret clearance is required after day 1.

Nice To Haves

Project experience in component design, analysis, and/or build of space or airborne hardware.
Experience with GD&T and tolerance analysis for designs and drawings.
Knowledge of DFMA principles and modern machining techniques.
Understanding of change management and processing engineering changes in a product data management tool.

Responsibilities

Design mechanical components for opto-mechanical systems using Creo.
Support assembly, integration, and testing activities in a laboratory environment.
Support the design, build, and test of EO/IR space hardware with manufacturing and mechanical engineers.
Create and revise opto-mechanical designs and drawings.
Generate assembly instructions and provide build support in coordination with technicians and other engineering disciplines.
Apply design-for-producibility and manufacturability principles.
Research component designs and materials for mechanical assembly design and analysis.
Generate detailed design drawings incorporating GD&T to maintain requirements.
Collaborate with cross-functional engineering and analysis teams on material selection, thermal management, precision mechanical mounting and motion, and structural optimization while balancing schedule constraints.
Create and revise designs and process engineering changes using a product data management tool.
Present work for peer reviews.
