Secret - Current At Raytheon, the foundation of everything we do is rooted in our values and a higher calling - to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today's mission and stay ahead of tomorrow's threat.

Our team solves tough, meaningful problems that create a safer, more secure world. Raytheon is an industry leader in Stealth Technology. We are involved in all phases of design, development, production, and maintenance of Low Observable (LO) antenna and Active Electronically Scanned Arrays (AESA) systems. We are currently looking for Stealth / Low Observable / Radar Cross Section (RCS) / Signature Management / Survivability Engineers to work on challenging, state-of-the-art technical projects.

Raytheon's Apertures and RF Department is seeking a Principal Antenna Design Engineer to join the Radome & Apertures team in McKinney, Texas. The candidate will support state-of-the-art ultra-wideband phased array antennas, individual antennas, and RF Low Observables (LO) within the Company. The selected candidate will work with various teams of engineers and scientists with backgrounds in AESAs, Antennas, Radomes, Computational Electromagnetics Modeling (CEM), RF Test, Mechanical, Structural and Thermal analysis, Material Science, Process and Manufacturing Engineering and survivable antenna technology.

The ideal candidate for this role will enjoy both theoretical design and hands-on engineering tasks. If you are looking for an opportunity to grow with a leader in the Defense Industry, this is the perfect opportunity for you! This position requires job duties to be performed onsite due to the sensitive nature of this work and the desire for in-person collaboration, however we offer flexible in-office hours and the ability to perform some job duties remotely.

What You Will Do
* Responsible for the hands-on design and realization of LO antennas, phased array antennas and passive RF components.

* Use computational electromagnetic analysis software to design and predict performance on various types of antennas and apertures (spiral, sinuous, Vivaldi, patch, slot, horn, ultra-wideband tightly coupled dipole arrays, etc.).

* Exhibit exceptionally high level of innovation, creativity, and initiative.

* Support customer programs through modeling and simulation of LO antennas or RF components/systems and leading teams that perform these functions.

* Provide technical solutions to a wide range of difficult problems involving antenna/sensor-based applications such as radar, electronic warfare, electronic attack, electronic support measures, communications, geolocation, direction finding, etc.

* Establish and maintain effective working relationships with internal and external customers. Represent the organization in providing solutions to difficult technical issues associated with specific projects.

* Mentor and guide more junior engineers and technicians in the design, build, and test phases of projects and programs.

* Work with interdisciplinary engineering teams including thermal, structural, mechanical, systems, etc.

* Participate in and guide the testing of RF hardware for required performance metrics: VSWR, insertion loss, gain, polarization, RCS.

* This 1st shift role will be 100% on-site and based in McKinney, TX. Qualifications You Must Have
* Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 8 years of prior work experience, or an Advanced Degree in a related field and minimum 5 years' experience.

* Engineering experience to include any combination of the following:
* Radar Cross Section (RCS) reduction, prediction, measurement, and analysis & simulation.

* Design, fabrication, and test of conformal antennas, apertures, and passive RF components (i.e. radiating elements, radomes, power dividers, couplers, transitions, multi-layer board designs, Frequency Selective Surfaces (FSSs), etc.).

* Designing, fabricating, and testing ultra-wideband phased array antennas such as Tightly Couple Dipole Arrays (TCDA), Vivaldi, Sliced Notch, Planar Ultra-wideband Modular Arrays (PUMA).

* Experience with RCS analysis tools such as X-Patch, SENTRi, FEKO, HFSS, CST or other company specific CEM analysis packages.

* Active and transferable 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
