Senior RF/MW Engineer

Kyocera International, Inc. (North America)•San Diego, CA

11d•$90,000 - $130,000•Onsite

About The Position

The Microwave RF Engineer is responsible for the development, testing, and validation of mmWave and RF technologies, actively contributing throughout the product development cycle. The role focuses on highly integrated wireless systems and advanced measurement techniques. Responsibilities include passive and active device characterization, cascaded measurements, and over-the-air (OTA) testing of horn and phased-array antennas. The engineer develops automated test setups, controls instrumentation, analyzes large datasets, and performs troubleshooting as needed. This position owns circuit- and system-level solutions for wireless chipsets, working closely with design teams and technicians. The role includes presenting technical results, interpreting schematics, supporting firmware or test program updates, and occasionally leading projects or mentoring team members.

Requirements

Master’s degree in Electrical Engineering or related field with 5+ years of relevant industry experience; or Bachelor’s degree with equivalent practical experience in RF/microwave engineering.
Ability to execute each essential duty at a high technical standard.

Responsibilities

Design, analyze, and validate RF and microwave mixed-signal circuits including amplifiers, mixers, filters, PLLs, and frequency synthesizers while supporting multiple time-sensitive project milestones.
Apply advanced RF measurement techniques including calibration and de-embedding, small-signal analysis, mixer spur analysis, linear and nonlinear device characterization, filtering, and EVM evaluation.
Perform repeatable and accurate RF characterization and data validation using Python and MATLAB; utilize data visualization tools (e.g., Power BI) as needed.
Operate and support RF laboratory equipment including vector network analyzers (VNA), spectrum/signal analyzers, signal generators, oscilloscopes, DC power supplies, LCR meters, and digital multimeters.
Support development of advanced microwave and millimeter-wave subsystems including RF front ends, radar receivers, wideband tuners, and synthesized sources.
Conduct conducted and over-the-air (OTA) antenna measurements with working knowledge of electromagnetics and 5G FR2 measurement standards; understand applicable compliance and industry standards for 5G products.
Develop, implement, and maintain automated test scripts in Python to control DUTs and interface with laboratory instrumentation.
Design and build comprehensive test setups for IC test keys and IC modules; analyze and optimize IC performance through bias adjustment and frequency tuning across operating bands.
Support firmware updates, microcontroller configuration, and serial bus interfaces as part of the device test infrastructure.
Generate clear, data-driven technical reports and presentations with accurate analysis and well-supported conclusions.
Collaborate with cross-functional teams including digital design, IC implementation, and third-party suppliers to define system-level analog and digital requirements.
Contribute to process development and continuous improvement initiatives; provide technical guidance or training when required.
Focus on developing power-optimized solutions while meeting system performance targets.
