Job description

We are seeking a Researcher in 5G/6G Communication Network Systems to conduct research on next-generation communication architectures and network technologies for Physical AI and embodied intelligent systems.

What You'll Work On

You will conduct research on network architectures, algorithms, protocols, and system mechanisms for future intelligent communication networks, including areas such as:

• Action-aware and task-aware network control, translating application and task requirements into communication policies
• Multimodal traffic importance modelling, identifying the relative importance, urgency, and timing requirements of different information flows
• Resource allocation, traffic prioritization, and network scheduling
• Cross-modal temporal coordination, including latency, jitter, synchronization, and inter-stream timing control
• Deterministic and predictable communication for latency-critical cyber-physical systems
• Adaptive reliability mechanisms according to application and task requirements
• Dynamic network resource orchestration across RAN, edge, transport, and computing resources
• Edge networking and intelligent RAN architectures supporting real-time network control and distributed computing
• Network protocol, signalling, and API design for communicating application context and network requirements
• Cross-layer and multi-domain optimization for communication and computing resources
• Experimental implementation and validation using network simulation, emulation, RAN platforms, or end-to-end system testbeds

Your research will contribute to next-generation communication architectures capable of supporting emerging applications such as robotic manipulation, autonomous inspection, immersive interaction, teleoperation, and industrial automation.

• Strong programming and algorithm development skills (e.g., Python, C/C++, or similar)
• Demonstrated publication record in relevant conferences or journals
• Ability to work in a multidisciplinary research environment spanning communications, networking, AI, and intelligent systems

Preferred Qualifications

Experience in one or more of the following areas would be advantageous:

• 5G/6G RAN architecture and resource management
• Deterministic networking, URLLC, or Time-Sensitive Networking
• Network scheduling, traffic engineering, and resource optimization
• Edge computing and communication–computation co-optimization
