* Design, develop and test rApps for the Non-RT RIC / SMO layer, using the R1 interface to consume data and issue A1 policies to the Near-RT RIC.
 * Design, develop and test xApps for the Near-RT RIC, using the E2 interface to implement near-real-time control loops.
 * Integrate rApps and xApps with SMO services, data pipelines and data layers (e.g. the R-NIB).
 * Collaborate with RAN and network engineers to translate use cases into working applications.
 * Design and implement CI/CD pipelines for automated build, test and deployment of RIC applications.
 * Ensure compliance with relevant O-RAN Alliance specifications (A1, E2, O1, R1) and coding standards.
