This position will be located at our headquarters in Syracuse, NY. Responsibilities
Design, develop, and execute test plans for radio drivers in alignment with O-RAN architecture and 3GPP specifications.
Validate O-RAN radio integration (O-RU/O-DU) including fronthaul protocols and CUSM-plane interfaces.
Perform functional, performance, regression, and stress testing of radio drivers across different hardware platforms.
Debug driver issues at platform level—working across kernel, hardware abstraction layers, and interface logic.
Collaborate with platform and software teams to reproduce, isolate, and resolve complex system-level issues.
Ensure compliance with O-RAN specifications, contribute to alignment with evolving O-RAN Alliance standards.
Develop and enhance automation scripts to improve regression coverage and test reliability.
Analyze logs and traces using tools such as Wireshark, QXDM, and platform-specific debuggers.
