Raytheon Technologies Mechanical Engineer - High Power Microwave in Tucson, Arizona

Raytheon Missiles & Defense Directed Energy Group is part of Raytheon Technologies Advanced Technologies (AT) product line, providing comprehensive, end-to-end HPM system solutions for various customers throughout the Department of Defense.

Raytheon’s Directed Energy Group consists of highly motivated, ambitious individuals with expertise in the areas of prime power engineering, pulsed power design & engineering, High Power Electromagnetic source design & engineering, novel antenna design & engineering, and diagnostics and effects testing. The Directed Energy Group reaches through and collaborates with numerous groups throughout Raytheon Technologies, collaborating with flight test and satellite systems support and tracking, large facility operations, maintenance, and engineering, sensor development and diagnostics; control and data acquisition systems, software and automation, materials fabrication, assembly, processing and coating, quality engineering, and document production, imaging and management.

The HPM Systems Mechanical Engineer position’s primary duty will be to leverage their knowledge of HPM (High Power Microwave) system architecture and best design principles and practices to work closely with Raytheon Scientists to develop manufacturable models of all subsystems and components of HPM systems.

In addition, the Mechanical Engineer’s duties will also include participation in all aspects of the design process of HPM Systems for Raytheon Technologies’ various customers.

Additional duties will include participation in mechanical engineering subgroups in project teams, active participation in pulsed power and microwave system design groups in development processes and efforts to include: technical report preparation, preparation of materials, content, and products for system design reviews, delivering presentations to customers, and participation in technical proposal development.

The candidate will also work with other key project team members to determine, guide, and build to optimal design parameters to meet HPM system key performance parameters.

The primary work location will be on-site at the Raytheon Tucson office; some travel will be required to meet and work with vendors and to support testing and other activities as needed.

U.S. Citizenship status is required as this position requires either an active U.S. Security Clearance or the ability to obtain one
