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).
IS-Wireless is a top European deep-tech innovator, awarded the EIC Seal of Excellence and holder of 10+ patents. As a NATO DIANA 2025 innovator, we operate as a dual-use company, building ultra-resilient, secure and resource-efficient 5G networks for both industrial and tactical applications.
Our patented Liquid RAN technology represents a new generation of open, disaggregated radio access designed for exceptional reliability, flexibility, and resource efficiency. It enables rapid restoration and redeployment of base stations, even in volatile or degraded environments.
We value creative problem-solvers, unconventional thinkers and deep domain experts who thrive in demanding scenarios.
Proven in Defense and Industry 4.0 Environments.
IS-Wireless powers resilient connectivity where others fail-supporting tactical 5G bubbles, autonomous robots, real-time AR maintenance, and mobile command units. From sovereign military networks to smart industrial campuses, our deployments prove the flexibility and reliability of our LiquidRAN™-based private 5G and 6G networks.
