Senior Wireless Test Engineer Job Lees Summit area,Lee's Summit Missouri USA,Engineering

Location: Lee's Summit

Lead lab and field validation of GM’s 4G and 5G cellular connectivity.
Translate detailed technical and regulatory requirements into comprehensive test strategies, test cases, and automated test scripts that validate end-to-end system performance across multiple networks, operators, and markets.
Define test methodologies, select tools and equipment, execute complex test campaigns, and drive issue resolution with internal teams and external partners.
Develop and execute RF performance and parametric test cases such as output power, sensitivity, ACLR, EVM, throughput vs. RSRP/RSRQ/SINR, spectrum mask.
Collaborate closely with hardware design, modem/software, systems engineering, regulatory, and back-end/cloud teams to clarify requirements and KPIs, prioritize defects and drive design or software changes, and improve test coverage and methodologies over time.
Provide clear, concise test reports and technical summaries for leadership, program teams, and external stakeholders.

Requirements

Bachelor’s degree in Electrical Engineering, Computer Engineering, Telecommunications, or related field.
5+ years of hands‑on experience in cellular wireless testing or validation (4G LTE and/or 5G ) in automotive, telecom, handset, or modem domains.
Strong understanding of cellular RF fundamentals (power, sensitivity, link budget, interference, fading).
4G/5G protocol stack (RRC, PDCP, RLC, MAC, PHY; NAS and core network interactions).
Mobility and roaming concepts, including handovers, reselection, and tracking areas.
Demonstrated experience developing test plans, test cases, and test scripts for RF performance and parametric checks, Cellular protocol procedures (attach, bearer setup, registration, security), Mobility/roaming, throughput, and latency characterization, Voice, data, SMS, and emergency call scenarios.
Hands‑on experience with cellular test equipment and tools, such as call boxes/network simulators (e.g., Keysight, R&S, Anritsu, Spirent, etc.), spectrum/network analyzers, signal generators, channel emulators, protocol analyzers and log tools (e.g., QXDM, QCAT, modem logs, Wireshark).
Strong data analysis and debugging skills, with the ability to interpret complex RF and protocol logs and narrow down root causes.
Proven ability to translate requirements into testable criteria and define the tools, instrumentation, and configurations needed for full coverage.
Excellent written and verbal communication skills, including the ability to document test methods, results, and recommendations clearly.
