• Run RF characterization and KPI testing using VSA, VSG, VNA, and spectrum analyzers.
• Validate the full radio chain, including chipset, PA, and activation network, and antenna.
• Build Python test frameworks and maintain regression testing for firmware and driver releases.
• Debug performance issues across RF hardware, firmware, drivers, PHY, and MAC.
• Support site surveys, RF planning, deployments, post deployment testing, and FCC pre compliance.
