Job Description Would you like to join an incredibly talented group of people, doing very challenging work, with the prime directive of “ Keeping Our Heroes Connected ”? THE OPPORTUNITY Silvus is seeking a full-time Senior Wireless Communication Systems Engineer who will report to the Senior Engineering Director on the Irvine Engineering team. This engineer will develop and validate wireless architectures and algorithms from requirements through implementation and field testing. This position is fully onsite, Monday through Friday. The location for this role is Silvus Technologies’ Engineering and R&D Office in Irvine, CA , near the vibrant Irvine Spectrum. The following is a list of at least some of the current essential job functions of the position. Management may assign or reassign duties and responsibilities at any time at its discretion. ROLE AND RESPONSIBILITIES Translate product and mission needs into measurable wireless system requirements, architecture and interface specifications, and verification plans across the 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; use the 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; 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. REQUIRED QUALIFICATIONS M.S. with minimum 4 years of relevant wireless system design experience or 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 the successful clearance of a background check.
