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.

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

• Advanced degree in Science, Technology, Engineering, or Mathematics (STEM) discipline. Degree must be obtained by start date.
• Experience using Computer Aided Design (CAD) software (such as SolidWorks, PTC Creo, Autodesk Inventor, CATIA, Siemens NX, or equivalent) to generate 3D models and mechanical assemblies.
• Experience creating or maintaining mechanical hardware documentation and engineering drawings adhering to industry drafting standards (such as ASME Y14 series or ISO).
• Experience may be obtained through on-the-job experience, research, coursework, or projects.

Qualifications We Prefer

• Advanced degree in Mechanical Engineering, Aerospace Engineering, or Mechatronics.
• Cumulative GPA of 3.0 or higher from an ABET-accredited institution.
• Experience with Model Based Engineering (MBE) or Model Based Definition (MBD).
• Previous hands-on testing, prototyping, or production support experience in an aerospace, defense, or high-reliability manufacturing environment.
• Strong analytical, diagnostic, and root-cause problem-solving skills applied to mechanical fixtures or test equipment.
• Demonstrated ability to collaborate effectively in a multi-disciplinary, fast-paced team setting.

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

This position requires a security clearance. DCSA Consolidated Adjudication Services (DCSA CAS), an agency of the Department of Defense, handles and adjudicates the security clearance process. More information about Security Clearances can be found on the US Department of State government website here: https://www.state.gov/m/ds/clearances/c10978.htm

As part of our commitment to maintaining a secure hiring process, candidates may be asked to attend select steps of the interview process in-person at one of our office locations, regardless of whether the role is designated as on-site, hybrid or remote.
