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

Join Raytheon's dynamic Test Solutions Engineering team, part of the Hardware Discipline Center, where we architect and deliver high-reliability test equipment vital to national defense. In this role, you will design, analyze, prototype, and implement advanced mechanical test fixtures and environmental test stations supporting complex weapon systems across their entire lifecycle-from early engineering development and high-rate factory production to field operations and long-term sustainment.

Occasional CONUS travel to customer sites or suppliers is generally required. International and longer-duration travel assignments are available but optional.

Key Responsibilities

• Research, plan, and design custom mechanical test solutions for vibration, thermal, hydraulic, radio frequency (RF), and electro-optical operational environments.


• Conceptualize and implement mechanical systems that integrate seamlessly with state-of-the-art test technologies.


• Utilize parametric CAD solid modeling tools to create comprehensive 3D assemblies and detailed 2D engineering drawing packages.


• Ensure all technical data packages adhere strictly to industry drafting standards, including ASME Y14 series or ISO geometric dimensioning and tolerancing.


• Integrate and validate test systems against stringent accuracy, repeatability, and reliability requirements.


• Evaluate production installations and collaborate with cross-functional engineering and manufacturing teams to diagnose malfunctions and implement design enhancements.

Qualifications You Must Have

• Bachelor's 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

• 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.
