Job summary

IS-Wireless is seeking a research-focused engineer to implement and prototype innovative algorithms for disaggregated RAN, security/Zero Trust, and RRM. You will design xApp/rApp applications using RIC API and E2/R2 interfaces, while deploying AI/ML-driven solutions in cloud-native environments with Kubernetes.

The role offers collaboration on cutting-edge 5G/6G architectures, opportunities to contribute to research and patents, and a chance to contribute to secure, low-latency telecom networks

Qualifications

• Strong Python skills for prototyping and AI/ML tasks.
• Solid understanding of 5G/6G architecture.
• Experience with cloud-native environments and Kubernetes.
• Familiarity with security concepts such as Zero Trust, TLS/PKI, IPSec.
• Ability to rapidly prototype and work with 3GPP documentation.
• Proficient English communication.

Responsibilities

• Implement and prototype innovative algorithms for disaggregated RAN, security/Zero Trust, and RRM.
• Design and implement xApp/rApp applications for the ecosystem using RIC API and E2/R2 interfaces.
• Deploy AI/ML-driven solutions for network optimization (e.g. reinforcement learning, swarm optimization).
• 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.

Job description

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 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
• 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).
• 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).

How We Work

Loyalty & team spirit — we have each other's backs, always.

Sincerity & openness — we say what we think, even when it's uncomfortable.

Courage & ambition — we take positions, defend them, and aim high.

"How can I help?" attitude — we help because we want to, not because we have to.

Out of the comfort zone — we build things that haven't been built before. That's the point.

Zero-latency — we act. No waiting, no procrastinating, no excuses.
