Job Description

Senior RAN / RF Expert – (Digital Twin, NVIDIA Aerial, Omniverse, AI, ML ) EU passport

Location: Sweden (Hybrid/Remote possible)
Start date: ASAP
Contract: Consultant / Freelance (long-term project)
Length: 6- 12 month
EU passport needed

Role Overview

We are looking for an experienced RAN / RF expert to support the creation and validation of a Digital Twin of the radio network (e.g., NVIDIA Aerial Omniverse concept).

The customer’s network is already operating at a high maturity level (TMF Level 4 Autonomous Network), and the Digital Twin will be used for advanced modelling, simulation, and “what-if” analysis.

Key Responsibilities

• Provide expert support in RAN performance engineering and optimization (4G/5G)
• Contribute to building a Digital Twin model of the RAN network for simulation and decision support
• Apply strong RF propagation knowledge for accurate modelling (outdoor & indoor)
• Support network analysis using KPIs (coverage, throughput, mobility, interference)
• Collaborate with stakeholders on requirements and validation of model accuracy
• Required Skills & Experience (Must-have)
• Strong hands-on experience as RAN Engineer / RF Optimizer (LTE + 5G NR)
• Solid understanding of radio propagation:
• outdoor propagation, terrain/clutter effects
• indoor propagation / penetration modelling
• Experience with RAN optimisation and troubleshooting:
• Coverage gaps, interference, mobility issues, HO tuning, KPI analysis
• Ability to work with limited initial requirements and support discovery discussions

Preferred / Nice-to-have

Experience with Digital Twin, network simulation, or modelling tools

Exposure to NVIDIA Aerial / Omniverse or similar simulation environments

AI / ML knowledge (e.g., predictive optimization, anomaly detection)

Python/data analytics experience

Nordic operator experience is a plus
