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.

Our mission is to develop best in industry technologies that align product capabilities to the needs of our customer. We empower our employees to leverage design commonality and innovation, balancing risk and rigor, to achieve predictable and affordable solutions.

The Guidance Electronics Team provides Electrical Systems Engineering to develop Guidance Electronics solutions for products across the Raytheon Missiles and Defense (RMD) portfolio. Our team develops missile Guidance Electronics Hardware. Our core electrical engineering responsibilities include architecture, analysis, requirements, integration, and test. Our core electrical engineering technologies include RF/RADAR, Navigation/IMU/GPS, Digital, and Power. We partner with several Electrical Product Team departments that provide the detailed design of our electrical products as well as missile level systems teams.

The role of the GPS Subsystems Engineer is to provide GPS electronics solution for missile products. GPS electronics solution includes architecture development, requirement definition, electronics design, analysis, modelling and testing. GPS Subsystem Engineer collaborates with missile level system engineers in developing requirements for the subsystem. They perform analysis and modeling to decompose requirements for GPS sub-assemblies and component designs.

What You Will Do

• Work environment is primarily in an office, but may include labs, field work, or a combination.
• Assignments may include analysis of hardware designs, subsystems, and components; architecting new electronic systems; developing and documenting subsystem requirements and test plans; peer reviews of designs as a subject matter expert; presentations to peers, management, and government customers; and root-cause failure investigations.
• Interface directly with suppliers of navigation or guidance electronics components, IMUs and GPSs, to monitor and manage programmatic activities and ensure compliance to requirements
• Missile Systems has a strong culture of mentoring; it is expected that employees will be both mentors and mentees.
