About The Position

The Effector RF Team at Raytheon is seeking a Principal Engineer to contribute to the architecture, analysis, design, and implementation of RF subsystems and sensors within missile products. The role provides technical expertise, leads small teams, and works with the Engineering organization to establish technology roadmaps, enable modernization, and support innovation. The engineer also interfaces regularly with government personnel and program leadership, and provides subject matter support and leadership to RF projects and team members. This is an onsite role in Tucson, Arizona. The position requires an active and transferable U.S. government security clearance before starting; U.S. citizenship is required for clearance eligibility, and the candidate must be able to obtain an interim clearance before the start date and special program access after starting. Relocation may be offered based on candidate eligibility.

Requirements

Bachelor of Science degree in Technology, Engineering, or Mathematics (STEM).
At least 8 years of relevant experience, including any combination of RF subsystem design, integration, or test; RF sensor design, integration, or test; and cross-discipline engineering collaboration to define RF subsystem requirements and evaluate performance.
Ability to obtain an interim U.S. government-issued security clearance before the start date and special program access after starting.
U.S. citizenship, as required for eligibility for a security clearance.
Active and transferable U.S. government-issued security clearance required prior to the start date.

Nice To Haves

Knowledge of RF component technologies, including circuit card assemblies (CCAs), waveguides, planar or printed antennas, RF modules, and/or monolithic microwave integrated circuits (MMICs).
Experience performing link budget analyses.
Understanding of antenna patterns and RF measurements with antennas and electronics.
Experience with phase noise, mixer conversion spurs, automatic gain control (AGC), sensitivity, intermodulation distortion (IMD), bit error rate, instantaneous bandwidth, adjacent channel interference, and ADC measurements or calculations such as Nyquist and SFDR.
Familiarity with spectrum analyzers, network analyzers, signal generators, and arbitrary waveform generators (ARB generators).
Understanding of electromagnetic interference (EMI) and electromagnetic vulnerability (EMV), including mitigation strategies in RF systems.
Excellent written communication and oral presentation skills.

Responsibilities

Specify, design, and test advanced RF sensors and subsystems across frequencies from MHz through millimeter-wave.
Decompose system-level requirements into detailed RF component requirements.
Measure RF components, sensors, and subsystems, including performance in chamber and range environments.
Model and analyze link budgets, RF cascades, electromagnetic emissions (EME), antenna patterns, phase noise, receiver sensitivity, transmitter power, spurious signals, modulation, isolation, and ADC characteristics.
Contribute to architecture, analysis, design, and implementation of RF subsystems and sensors in missile products.
Provide technical expertise, lead small teams, and support RF projects and team members.
Work with the Engineering organization to establish technology roadmaps, enable modernization, and contribute to innovation.
Interface with government personnel and program leadership.
