Data Engineer IV
Denver, CO (Hybrid)
JOB SUMMARY
Charter is a major telecommunications firm providing connectivity services to millions of customers. Charter's Infrastructure Intelligence and Analytics (IIA) team builds and operates the data platform and AI agent infrastructure that powers proactive network monitoring and autonomous investigation for Charter's network operations. As part of this group, the Data Engineer IV designs, builds, and maintains the ETL pipelines and data infrastructure that feed the IIA Data Lake, anomaly detection models, and AI agents. This role focuses on constructing robust, scalable data pipelines using Spark/Scala, ensuring data quality and availability across a growing portfolio of network data sources, and enabling downstream consumers (data scientists, agents, dashboards) to access reliable, well-structured data.
MAJOR DUTIES AND RESPONSIBILITIES
- Design, develop, and maintain scalable ETL pipelines using Apache Spark (Scala) to ingest, transform, and load network data into the IIA Data Lake.
- Onboard new data sources (network telemetry, syslogs, SNMP traps, device configuration data, ticketing systems) by building ingestion pipelines from raw source to query-ready format.
- Implement monitoring and alerting solutions to ensure data pipeline reliability and performance.
- Develop and manage deployment pipelines to facilitate continuous integration and delivery of data engineering solutions.
- Manage and optimize data storage solutions, including distributed file systems, relational databases, flat files, and external sources accessed via API.
- Implement data quality checks, validation rules, and automated testing to ensure pipeline reliability and data integrity.
- Optimize pipeline performance for large-scale data processing (billions of events per day) across batch and mini-batch processing patterns.
- Manage and evolve data schemas, partitioning strategies, and storage formats to support efficient querying and downstream consumption.
- Support data backfills and recovery when upstream issues or schema changes require reprocessing.
- Collaborate across teams to ensure data solutions align with existing production architectures and business requirements.
- Work with data scientists and agent developers to understand data requirements and deliver datasets that support anomaly detection models and AI agent workflows.
- Provide technical guidance on data engineering best practices and methodologies.
- Document and communicate data engineering processes and standards to business-intelligence, data, and analytics professionals with varied backgrounds.
- Continuously evaluate and improve data engineering tools and approaches to enhance performance and efficiency.
- Perform other duties as required.
