Raytheon Technologies Scientist II - Particle Acceleration in Tucson, Arizona

Raytheon Missile& Defense provides comprehensive expertise in high power electromagnetics (HPEM); pulsed power engineering, diagnostic instrumentation

and effects testing; radio frequency (RF) and particle code simulation; airborne flight test and satellite systems support and tracking; large system operations, maintenance, and engineering; sensor development and

diagnostic instrumentation; computer control and data acquisition systems, software and automation; materials fabrication, assembly, processing and coating; quality engineering; and document production, imaging and configuration management. Key growth opportunities include the integration of directed energy weapons with combat platforms. RMD is a leader in development of linear accelerator technology for government and commercial applications.

The Scientist II will provide significant contributions to novel concepts in directed energy (DE) applications, focusing on concepts and principles of particle accelerator technology design, prototyping, testing, and manufacturing, to pioneer, demonstrate, simulate and test the performance and impacts of novel designs for national defense applications.

The successful candidate will develop novel approaches and proposed solutions to meet overall program and device performance objectives.

The successful candidate will have demonstrated successful experience in the physics and technology of particle accelerator and particle beam systems, and nuclear physics.

Experience in plasma physics is a plus. The Scientist II will be expected to provide modeling, simulation and analysis, and develop designs, test prototypes, and interact across various departments to lead the integration of components and subsystems into larger DE systems.

The Scientist II will write and develop proposals for Raytheon innovations in particle accelerator technologies and provide project leadership for specific efforts through frequent interaction and coordination with customers, principle investigators, scientists, project leaders, engineers, and technical support personnel. An effective candidate will guide the work of Scientists I, Mechanical Engineers, Electrical Engineers, and Technician positions associated with DE projects and programs. This is a full-time position.

U.S. Citizenship status is required as this position needs an active U.S. Security Clearance as of day one of employment.
