What You Will Do

Join the Raytheon Hardware Engineering Organization and contribute mechanical engineering expertise to mission-critical defense systems across radar, missile, and command-and-control platforms. In this role, you will participate across the entire product lifecycle-from initial concept design and structural/thermal analysis to rapid prototyping, design verification testing, and factory support. Working in a collaborative, cross-functional environment alongside systems, electrical, and manufacturing engineers, you will solve complex technical challenges to deliver robust, high-reliability mechanical solutions.
Occasional CONUS travel to customer sites or suppliers is generally required. International and longer-duration travel assignments are available but optional.

Key Responsibilities:

• 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.
