The ideal candidate is comfortable working at the intersection of RF hardware, software, and automation — executing test campaigns, debugging complex system issues, and collaborating closely with integration, development, and automation teams to ensure product quality and standards compliance. ### Export Control Requirement Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Key job responsibilities ### Standards & Test Expertise - Maintain strong working knowledge of 3GPP standards (LTE/5G NR) and the O-RAN stack (O-DU, O-CU, O-RU, fronthaul/midhaul interfaces, Open Fronthaul specifications). - Stay current with conformance test specifications/lists (e.g., 3GPP TS 38.141/36.141 series, O-RAN conformance and interoperability test plans) and translate them into executable test cases. - Understand RF, protocol stack layers (PHY/MAC/RLC/PDCP/RRC), and call-flow behavior well enough to interpret test results and identify root causes. - Design new test cases to extend coverage for emerging 3GPP/O-RAN features, conformance requirements, and product-specific scenarios. ### RF & Test Equipment - Be familiar with RF devices and lab test equipment, including UE simulators, core network emulators, channel emulators, signal generators/analyzers, and protocol analyzers. - Be familiar with UE evaluation test equipment and procedures used to validate device performance against 3GPP/O-RAN requirements. - Be familiar with debug and diagnostic tools such as QXDM and other over-the-air (OTA) log analysis tools to troubleshoot UE and network behavior. ### Test Execution & Data Analysis - Plan and execute test cases on lab setups covering functional, performance, conformance, and regression testing. - Collect, organize, and analyze test data/logs (e.g., protocol traces, KPIs, OTA logs) to assess pass/fail criteria. - Triage test failures — distinguishing between HW faults, SW bugs, configuration issues, and test environment problems — and drive issues to resolution with the right owning team. - Produce clear, well-documented test reports and defect write-ups for engineering and stakeholders. ### Cross-Functional Collaboration - Work closely with Hardware, Software, Integration, and Automation teams to coordinate test schedules, align on test setup requirements, and resolve blocking issues quickly. - Support the integration team in bringing up new HW and SW builds on the test bench, including initial sanity checks and bring-up validation. - Act as a liaison between test findings and development teams, providing actionable feedback to accelerate fixes. ### Lab & Test Setup Ownership - Build, configure, and maintain new lab test setups, including equipment racking, cabling, network configuration, and tool installation. - Continuously improve existing setups for reliability, repeatability, and test coverage. - Perform HW and SW upgrades/updates on test equipment and devices under test (DUTs), ensuring minimal downtime. - Debug and resolve lab/setup-level issues (connectivity, equipment faults, synchronization, environment instability) to keep test lines operational. - Maintain accurate setup documentation/inventory (topology diagrams, equipment lists, firmware/software versions). ### Scripting & Automation - Develop and maintain scripts (Python, Shell, TCL, or similar) to automate repetitive test procedures and setup configuration tasks. - Build or extend automated test frameworks to increase test throughput and reduce manual effort. - Integrate automated tests into CI/CD or regression pipelines where applicable, and maintain test automation health. ## At a glance - Posted by the employer: Oct 13, 2026 - First seen by OpenNash: Oct 18, 2026 -
