About The Position

Silvus Technologies, a wholly owned subsidiary of Motorola Solutions, is seeking a full-time Senior Wireless Communication Systems Engineer for its Irvine Engineering team. The position reports to the Senior Engineering Director and is based fully onsite, Monday through Friday, at Silvus Technologies’ Engineering and R&D Office in Irvine, California. The engineer will develop and validate wireless architectures and algorithms from requirements through implementation and field testing, helping keep customers’ personnel connected in mission-critical environments. The role translates product and mission needs into wireless requirements, architectures, interface specifications, and verification plans across RF, PHY, MAC, and network layers. It involves developing and evaluating modem and signal-processing algorithms; modeling link and system performance; collaborating with FPGA, embedded software, and RF teams on implementation and optimization; and planning and conducting simulation, bench, and field tests. The engineer documents technical work, presents findings, evaluates existing products and emerging technologies, and contributes to future product architecture and enhancements. Occasional travel may be needed for customer interactions, testing, or demonstrations. The work takes place in an office environment, with occasional exposure to heat, cold, and allergens during field tests or demonstrations. Physical duties include lifting equipment weighing up to 20 pounds, bending and reaching, kneeling or squatting, and walking or moving in laboratories.

Requirements

M.S. with a minimum of 4 years of relevant wireless system design experience, or a Ph.D. in Electrical Engineering, Computer Engineering, Communications Engineering, Computer Science, or a related engineering field; preferably focused on wireless communications and signal processing.
Hands-on experience designing or integrating wireless modem functions and understanding interactions among the PHY, MAC, and higher layers.
Working knowledge of RF propagation, link budgets, fading, interference, and channel modeling for mobile wireless systems.
Strong foundation in digital communications and signal processing, including MIMO, OFDM, synchronization, channel estimation, equalization, and channel coding.
Understanding of RF systems and impairments, including automatic gain control, phase noise, carrier and sampling offsets, and I/Q imbalance, and their effects on system performance and digital compensation.
Proficiency in MATLAB for algorithm development, simulation, data analysis, and performance characterization.
Must be a U.S. Citizen due to clients under U.S. government contracts.
Employment is contingent upon successful clearance of a background check.

Nice To Haves

Experience with mobile ad hoc networks (MANETs), including distributed medium access, routing, mobility, and multi-hop performance.
Experience taking wireless systems from simulation and prototype through integration, laboratory characterization, and field validation.
Knowledge of RF front ends, antennas, link budgets, and practical tradeoffs between waveform algorithms and hardware constraints.
Experience operating in congested or contested spectrum, including interference detection and mitigation, RF sensing, or adaptive/cognitive radio.
Hands-on fixed-point design and verification, including quantization analysis and reference models for FPGA or embedded software implementations.
Experience with RF test equipment, over-the-air measurements, and systematic laboratory troubleshooting.
Working knowledge of TCP/IP networking and its interactions with wireless links and mobile ad hoc networks.
Experience using Python or C/C++ for analysis, prototyping, test automation, or debugging.
Ability to organize work independently, prioritize competing tasks, and collaborate across systems, RF, FPGA, software, and test teams.
Clear technical writing and communication skills, including the ability to explain performance tradeoffs and test results to colleagues and customers.

Responsibilities

Translate product and mission needs into measurable wireless system requirements, architecture and interface specifications, and verification plans across RF, PHY, MAC, and network layers.
Develop and evaluate modem and signal-processing algorithms, including synchronization, channel estimation, MIMO/OFDM processing, and adaptation to changing channel conditions.
Build link- and system-level models to assess range, throughput, latency, reliability, and performance under mobility, interference, and challenging propagation, and use results to guide design tradeoffs.
Work with FPGA, embedded software, and RF teams on implementation specifications, fixed-point modeling, test vectors, integration, and performance optimization.
Plan and execute simulation, bench, and field tests; correlate measured results with models, investigate performance gaps, and drive issues to resolution.
Document architectures, algorithms, assumptions, test methods, and results, and present technical findings and recommendations at design reviews.
Assess current products and emerging technologies, identify opportunities to improve performance and robustness, and contribute to future product architecture and enhancements.
Travel occasionally to support customer interactions, testing, or demonstrations, as needed.
