5G/6G R&D Software Developer Build the future of ultra-resilient connectivity! We usually respond within a day Key Responsibilities Implement and prototype innovative algorithms for disaggregated RAN, security/Zero Trust, and Radio Resource Management (RRM). Potentially with the use of L1/L2/L3 emulators (commercial ones as well). Design and implement xApp/rApp applications for the O-RAN ecosystem using RIC API and E2/R2 interfaces. Deploy AI/ML-driven solutions for network optimization (e.g. based on reinforcement learning, swarm optimization or similar Work with cloud-native technologies (Kubernetes) to deploy and scale network applications. Collaborate on research projects that may lead to patent applications (and/or papers). Integrate selected security solutions e.g. encryption (TLS/PKI, IPSec), Zero Trust architectures. Requirements Strong programming skills in Python (prototyping, AI/ML) - JAVA or C/C++ knowledge will be a plus. Good understanding of 5G/6G architecture and O-RAN Alliance standards (RIC, E2AP, R1, O-CU/O-DU). Experience working in cloud-native environments: Kubernetes, CI/CD. Basic knowledge of security principles (e.g. Zero Trust, TLS/PKI, IPSec). Ability to rapidly prototype solutions and work with technical documentation (3GPP, O-RAN). Good command of English. Nice-to-Have Experience in Radio Resource Management (scheduling, interference management, load balancing). Hands-on experience creating xApp/rApp applications (RIC SDK, E2/R1 interface). Practical AI/ML experience: reinforcement learning, anomaly detection. Knowledge of libraries and HW suitable for fronthaul/midhaul optimization (eCPRI, DPDK, eBPF, SmartNIC/GPU). Experience in MLOps (deploying AI models in telecom environments). Familiarity with network simulators: MATLAB, ns-3. R&D experience (publications, patents).
