Software Engineer (5G/6G, O-RAN, AI)
Build the future of ultra-resilient connectivity!
Role Mission
To develop innovative software solutions for next-generation 5G/6G networks, focusing on O-RAN architecture, AI-driven network optimization, and secure disaggregated RAN systems. You'll be at the forefront of creating intelligent xApps/rApps that revolutionize how networks operate.
Key Responsibilities
Develop and prototype innovative algorithms for disaggregated RAN, security/Zero Trust, and Radio Resource Management (RRM).
Design and implement xApp/rApp applications for the O-RAN ecosystem using RIC API and E2 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, microservices) to deploy and scale network applications.
Collaborate on research projects that may lead to publications and patent applications.
Integrate security solutions including Zero Trust architectures, TLS/PKI, and IPSec protocols.
Requirements
Strong programming skills in Python (prototyping, ML/AI) - C/C++ knowledge is a plus.
Good understanding of 5G/6G architecture and O-RAN Alliance standards (RIC, E2AP, O-CU/O-DU).
Experience working in cloud-native environments: Kubernetes, microservices, CI/CD.
Basic knowledge of security principles (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 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).
