This means the successful candidate is expected to report to the GM Global Technical Center in Warren, MI three times per week, at minimum [or other frequency dictated by the business if more than 3 days].**The Role**The Senior Wireless Test Engineer – Cellular Systems will lead lab and field validation of GM’s 4G and 5G cellular connectivity, ensuring robust voice, data, and safety‐critical services for connected vehicles. This role is responsible for translating 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. Translate system, feature, and regulatory requirements into structured test plans, test cases, and scripts covering lab and field validation for cellular connectivity. Identify tools, test equipment, fixtures, and environments required to fully validate requirements (e.g., RF chambers, call boxes, loggers, automation frameworks, simulators, load generators). * Develop and execute RF performance and parametric test cases (e.g., output power, sensitivity, ACLR, EVM, throughput vs. RSRP/RSRQ/SINR, spectrum mask).* Specify and use RF test equipment such as signal generators, spectrum/network analyzers, OTA chambers, and channel emulators.* Analyze RF measurements, correlate with requirements and KPIs, and drive corrective actions with hardware and modem engineering teams.Drive test data management: logging, parsing, metrics dashboards, and traceability between requirements, test cases, and results. Debug, Analysis, and Cross‐Functional Collaboration**Your Skills & Abilities (Required Qualifications)*** 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 NR) 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.* Perform deep‐dive analysis of field and lab issues involving RF, protocol, and service‐level failures; reproduce and triage with modem suppliers, network operators, and internal teams.* 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* Improve test coverage and methodologies over time.* Provide clear, concise test reports and technical summaries for leadership, program teams, and external stakeholders.**What Can Give You a Competitive Advantage (Preferred Qualifications)*** Master’s degree in a related engineering field.* Knowledge of Hardware design, PCB, and traces.* Familiarity with emergency call regulations, public safety requirements, and regional differences in emergency services.* Experience with test automation frameworks (Python or similar) for cellular/RF testing, including scripting for call box control and log parsing.* Knowledge of operator certification, conformance, and regulatory test processes (e.g., PTCRB, GCF, carrier‐specific programs).* Experience with multi‐RAT and multi‐SIM devices, as well as coexistence with other radios (Wi‐Fi, Bluetooth, GNSS).* Background in requirements management and traceability tools, and in building coverage metrics for large test suites.Experience with automotive connectivity or telematics control units (TCUs), including in‐vehicle integration and back‐end/cloud connectivity. * The expected base compensation for this role is: $106,600 - $165,700. Actual base compensation within the identified range will vary based on factors relevant to the position.* Bonus Potential: An incentive pay program offers payouts based on company performance, job level, and individual performance.* Benefits: GM offers a variety of health and wellbeing benefit programs.
