Country: United States of America

Location: US-AZ-TUCSON-M02 ~ 1151 E Hermans Rd ~ BLDG M02

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

Security Clearance Type: DoD Clearance: Secret

Security Clearance Status: Ability to obtain INTERIM U.S. government issued security clearance is required prior to start date

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 Team at Raytheon is seeking a talented Senior Engineer to join our team in Tucson, AZ.

The candidate will be responsible for contributing to the analysis, design, and implementation of RF subsystems and sensors within missile products. The selected candidate will be expected to contribute RF subsystem/sensor support as part of an interdisciplinary team.

This position is an onsite role, located in Tucson, AZ.

What You Will Do

• Design, test, and integrate RF sensors and subsystems across frequencies from MHz through millimeter-wave.
• Support the decomposition of system-level requirements into detailed RF component requirements.
• Measure RF components/sensors/subsystems, including performance in chamber and range environments.
• Perform modeling and analysis of link budgets, RF cascades, electromagnetic emissions (EME), antenna patterns, phase noise, receiver sensitivity, transmitter power, spurious signals, modulation, isolation, and ADC characteristics.

Qualifications You Must Have

• Bachelor of Science degree in Technology, Engineering, or Mathematics (STEM)
• A minimum of 5 years of prior relevant experience, or an advanced degree in a related field and minimum 3 years of experience to include any combination of the following:
  • Design, integration, and/or test of RF subsystems
  • Design, integration, and/or test of RF sensors
  • Experience interacting across engineering disciplines (e.g. Systems, Mechanical, SW, Algorithms, etc.) to define RF subsystem requirements and evaluate performance
• Ability to obtain INTERIM U.S. government issued security clearance is required prior to start date with the ability to obtain special program access after start.

Qualifications We Prefer

• Knowledge of RF component technologies, including circuit card assemblies (CCAs), waveguides, planar/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 in concepts such as phase noise, mixer conversion spurs, automatic gain control (AGC), sensitivity, intermodulation distortion (IMD), bit error rate, instantaneous bandwidth, adjacent channel interference, and ADC measurements/calculations (Nyquist and SFDR).
• Familiarity with equipment such as Spectrum Analyzers, Network Analyzers, Signal Generators, and Arbitrary Waveform Generators (ARB Generators).
• Understanding of electromagnetic interference (EMI) and electromagnetic vulnerability (EMV) along with mitigation strategies in RF systems.
• Excellent written communication and oral presentation skills.

What We Offer

Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world. At RTX we value: Safety, Trust, Respect, Accountability, Collaboration, and Innovation.
