SECURITY CLEARANCE:

DoD Clearance: Secret
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.
The Effector RF Products Team at Raytheon is seeking a talented Principal Engineer to join our team in Tucson, AZ. The candidate will be working on a small program team that provides unique RF services and capabilities to our customer. We are developing digital signal processing (DSP) solutions that add new capabilities to existing RF hardware and will soon begin a hardware refresh effort utilizing modern RF transceiver and DSP architectures. As this is a small program team, the ideal candidate will be experienced in both RF systems and RF signal processing design and analysis.
The candidate will be responsible for contributing to the architecture, analysis, design, and implementation of RF subsystems, sensors, and embedded signal processing algorithms within a complex emerging missile product. The selected candidate will be expected to provide technical expertise, lead small teams, and work with the Engineering organization to establish technology roadmaps, enable modernization, and contribute to general innovation. In addition, the candidate will interface with government personnel and program leadership on a regular basis. The candidate will be responsible for providing expertise, leadership, and subject matter support to RF projects and team members.
This position is an onsite role, located in Tucson, AZ.

POSITION ROLE TYPE:

Onsite
U.S. Citizen, U.S. Person, or Immigration Status Requirements:
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

WHAT YOU WILL DO

• Specify, design, and test advanced RF sensors, subsystems, and embedded signal processing algorithms across frequencies from MHz through millimeter-wave.
• Decompose system-level requirements into detailed RF component and algorithm requirements.
• Measure RF components/sensors/subsystems, including performance in chamber and range environments.
• Perform modeling and analysis of link budgets, RF cascades, signal processing chains, antenna patterns, phase noise, receiver sensitivity, transmitter power, spurious signals, modulation, isolation, and ADC characteristics.
• Utilize statistical techniques such as Monte Carlo simulation to perform sensitivity analyses and execute design trades.
• Support software and configurable logic teams with implementation and maturation of signal processing algorithms in tactical hardware.
• Support simulation team with implementation and integration of RF HW models into system performance simulation.
• Support production team with troubleshooting activities, assessing impact of non-compliant HW on system performance, and requirements re-allocation.
