Salary Range: $75-79/hr on W2
Introduction
We are seeking a highly technical Wireless System Validation Engineer to drive the qualification and optimization of our next-generation cellular products. In this role, you will be responsible for the end-to-end validation of cellular modem performance, focusing on 5G NR (SA/NSA) and LTE-A technologies. You will bridge the gap between wireless HW development and system-level deployment, by understanding compliance with 3GPP standards and carrier requirements while maintaining industry-leading performance in power, sensitivity, and throughput.
Required Skills & Qualifications
Mid level System Validation Engineer with min 5 years of experience
Education: B.S. or M.S. in Electrical Engineering, Telecommunications, or a related field.
Deep understanding of 5G NR (Standalone and Non-Standalone) and LTE-A features like Carrier Aggregation (CA), MIMO, Beamforming, and VoLTE/VoWiFi.
In-depth familiarity with 3GPP protocols and the mobile device-to-network registration and call-flow processes.
Proficiency with RF lab equipment, including Spectrum Analyzers, Signal Generators, Power Meters, and Vector Network Analyzers (VNA).
Strong proficiency in Python for test script development and data analysis.
Experience using diagnostic tools such as QXDM, QCAT, Wireshark, or similar modem logging software.
Prior work experience at client or in client's Industry
Applicants must be able to work directly for Artech on W2
Preferred Skills & Qualifications
Background in field testing, drive testing, or Inter-Operability Testing (IOT) with infrastructure vendors (Ericsson, Nokia, Samsung).
Knowledge of RF front-end components (PA, LNA, Switches, Filters) and how they impact system-level cellular performance.
Day-to-Day Responsibilities
Define, develop, and execute comprehensive test plans for cellular modem validation across various radio access technologies (5G NR FR1/FR2, LTE-A, UMTS).
Perform deep-dive log analysis of the cellular protocol stack (L1, MAC, RLC, RRC, and NAS layers) to identify and root-cause signaling failures, handovers, and throughput drops.
Characterize key performance indicators (KPIs) such as RSRP, SINR, BLER, and Peak Throughput under varying network conditions (fading, interference, and mobility).
Design and maintain scalable automation frameworks using Python to increase test coverage and efficiency in lab and regression environments.
Collaborate with Firmware, Hardware, and System teams to debug complex system-level issues.
Operate and configure high-end cellular network emulators and RF test equipment for both signaling and non-signaling test modes.
