We are seeking an experienced Data Engineer to join a large-scale Billing Transformation programme. The engineer will be responsible for sourcing telemetry data, building scalable data pipelines, supporting rating logic, and preparing billing-ready outputs for SAP invoicing.

This role requires strong hands-on experience in AWS Glue, Snowflake, Python, PySpark, SQL, and CI/CD practices. The candidate will also be responsible for implementing data quality checks, reconciliation controls, audit trails, exception handling, and operational monitoring to ensure billing accuracy.

This is a critical engineering role supporting the transformation of raw telemetry usage data into rated, validated, and invoice-ready billing data.

• Build and maintain data ingestion pipelines from telemetry and usage data sources.
  
• Develop scalable ETL/ELT pipelines using AWS Glue, PySpark, Python, and SQL.
  
• Support both batch and event-driven data ingestion patterns.
  
• Ensure data pipelines are reliable, performant, scalable, and cost-efficient.
  

• Create and maintain curated usage datasets in Snowflake.
  
• Design efficient data models, tables, views, and processing layers for downstream billing use cases.
  
• Optimize SQL queries, warehouse usage, partitioning strategies, and performance.
  
• Support analytics, validation, and reconciliation use cases on Snowflake.
  

• Support implementation of rating logic for usage-based billing.
  
• Prepare billing-ready datasets for invoice processing.
  
• Generate data outputs and feeds required for SAP invoicing.
  
• Work on pricing, usage calculation, billing rules, and financial data transformation logic.
  
• Ensure raw telemetry data is transformed into accurate, validated, and invoice-ready records.
  

• Design and implement data quality checks across ingestion, transformation, rating, and billing layers.
  
• Build reconciliation controls to validate data completeness, accuracy, and consistency.
  
• Implement audit trails for billing data movement and transformation.
  
• Create exception-handling and error-management processes for failed or inconsistent records.
  
• Support root cause analysis for billing discrepancies and data issues.
  

• Build and support CI/CD pipelines for data engineering deployments.
  
• Work with tools such as GitHub Actions, GitLab CI, Jenkins, AWS CodePipeline, or similar.
  
• Implement operational monitoring, alerts, dashboards, and pipeline health checks.
  
• Maintain technical documentation, runbooks, and support procedures.
  
• Collaborate with engineering, finance, billing, and operations teams to ensure smooth delivery.
