Other Skills : Power BI, Spark, ETL, ELT, Cloud Technologies
Job Description:
• Experience & Domain Knowledge: 6+ years of experience in data analytics or a related field, with a substantial portion in the telecommunications industry preferably in the networking experienced in data analysis/data scientist roles.

• AI/ML & LLM Proficiency: Experience with machine learning or advanced analytics techniques. Exposure to AI/ML frameworks (such as scikit-learn or TensorFlow) and familiarity with Large Language Models (LLMs) or natural language processing is a big plus – you’re comfortable exploring new AI-driven approaches to glean insights from data (structured or unstructured).
