• Perform exploratory data analysis, feature engineering, and support analytical use cases like anomaly detection, forecasting, and optimisation.


• Collaborate with data scientists/ML engineers to enable model training, deployment, and translate insights for stakeholders.


• Build and operate cloud-based data solutions across GCP, Azure, and AWS using tools like Databricks, Kubernetes, and CI/CD practices.


• Ensure strong data quality, governance, and compliance by implementing monitoring, resolving data issues, and managing metadata, lineage, and security.

What makes you perfect for the role

• Bachelor’s degree in Computer Science, Data Engineering, Telecommunications, Engineering, or a related field, with 4+ years of relevant experience.


• Proven experience building production-grade data pipelines and analytical solutions, ideally in telecommunications or network environments.


• Hands-on expertise with cloud platforms (GCP, Azure, AWS) and distributed processing tools like Spark/Databricks.


• Strong technical skills in SQL, Python, and knowledge of network concepts and KPIs (performance, fault, capacity, availability).
