Senior/Principal RAN Digital Twin & AI Simulation Engineer
Core
Lead the development of a multi-RAT digital twin for Open RAN solutions to simulate production RAN software (scheduler, MAC, PHY) in a closed loop with channel and UE models, enabling feature design and validation without physical radio setups.
Role type
Senior individual-contributor wireless systems engineer (digital twin & AI simulation)
Builds
Scalable engineering platform for LTE, 5G NR, and 2G feature development, regression testing, and performance optimization
Domain
Telecommunications (Open RAN, 5G/4G/LTE) + AI/ML
Deliverable
production ML models
Required skills
Wireless systems engineering, RAN simulation, production software development, AI/ML integration, neural network modeling, channel estimation, MAC scheduler optimization, link adaptation, power control, mobility management, interference analysis, calibration methodologies, surrogate modeling
Preferred skills
Multi-RAT expertise, closed-loop simulation architecture, high-fidelity vs rapid surrogate model trade-offs, field/lab data calibration
Technologies
LTE, 5G NR, 2G, Open RAN, PHY, MAC, scheduler, neural networks
Responsibilities
Evolve existing LTE end-to-end simulator into a scalable engineering platform; define multiple fidelity levels for the digital twin; establish repeatable calibration methods against lab or field reference data; execute production RAN software in a closed loop with network models; support evidence-based pre-validation for feature development and regression testing.
Seniority
