With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can.

We deliver solutions that help our nation and allies defend freedoms and deter aggression, creating a safer, more secure world. Join us and help shape the future of aerospace and defense.

Raytheon's Receiver/Exciter & Processing Architecture (REPA) Department is the focal point for receiver, exciter, beam steering, and signal processing technology within the company. Our department is responsible for the design, development, integration, and lifecycle support of Raytheon's radar product portfolio.

We are seeking a Principal Hardware Integration, Analysis & Test Engineer excited about the opportunity to sit at the intersection of radar hardware, firmware, software, and signal processing and make it all work together. Join a growing Integration & Test Suite (ITS) team whose common toolset currently supports more than six active radar programs across S-, C-, X-, and UHF-Band systems.

Dig into RF and IQ data to find the root cause of hard problems — the kind where the answer isn't obvious and the stakes are real.

What You Will Do:

Perform Receiver/Exciter hardware, software, and firmware design verification tests across multiple radar bands and programs and figure out what the data is telling you.
Resolve complex technical issues seen during design, integration, and test of Radar Receiver and Exciter sub-systems.
Build data analysis tools that give engineers and technicians answers faster — and eventually, building Artificial Intelligence/Machine Learning tools do some of the heavy lifting.
Work directly with hardware designers, firmware developers, software and systems engineers — you'll need to speak all four languages.
Hands on hardware test and troubleshooting.
Write, use, and maintain software that controls, tests, and characterizes real radar hardware — from module level all the way to system integration.
Interface directly with program engineering, production, and systems teams.
This role is 100% on-site and will be based in Tewksbury, MA or Marlborough, MA. Some travel is to be anticipated between multiple sites including Andover, MA and Pelham, NH.

Qualifications You Must Have:

Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 8 years of prior relevant experience.
5+ years’ experience in two or more of the following areas:
- Radar system or subsystem integration, verification, and validation
- Programming in MATLAB or C/C++
- Microwave/RF system, subsystem, and/or Circuit Card Assembly design or test
The ability to obtain and maintain an Interim Secret U.S. government issued security clearance is required prior to start date. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.

Qualifications We Prefer:

Experience with IQ and signal processing analysis in MATLAB, C/C++, Python, or equivalent.
Experience with Linux and Git.
Experience with Radar Receiver/Exciter design and/or design verification testing.
Familiarity with radar system troubleshooting, root cause identification, and corrective action documentation.
Technical background in high-speed data converter test/characterization, radar system calibration, digital signal processing, cascade analysis, or frequency planning.
Exposure to AI/ML models or statistical process control concepts.
Self-starter capable of working independently and as part of a small, collaborative technical team.
Active / Existing Secret U.S. Security Clearance.

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.
This position offers relocation based on candidate eligibility.
