Mission

The Data Engineer (EVA) is responsible for designing, building, maintaining, and stabilizing big, scalable data pipelines and the Business Semantic Layer (BSL) across the Enterprise Data Warehouse (EVA) platform environment. This position ensures 24/7 platform availability, high data accuracy across telecom network feeds (rated/unrated CDRs, MoMo, RGS), and reliable pipeline execution to support enterprise BI and executive analytics.

Key performance areas

• ETL/ELT Pipeline Management: Design, deploy, and maintain automated data pipelines ingesting high-volume telecom network feeds (rated/unrated CDRs, Mobile Money/MoMo events) into the EVA Data Warehouse.
• Business Semantic Layer (BSL): Develop, optimize, and maintain semantic layer tables, views, and data models that power enterprise reporting and cross-functional business KPIs.
• Batch Operations & Re-runs: Plan, deploy, and monitor complex, multi-day historical batch re-runs and sequential cluster data recoveries using persistent terminal tools (e.g. Linux screen sessions).
• Node & Cluster Operations: Monitor cluster health, YARN resource allocation, and distributed query engines (Presto, Trino, Hive, Hadoop) to resolve processing bottlenecks and prevent node failures.
• Production Support & Maintenance: Support platform stability during node upgrades, OS patching, datacenter maintenance, and software releases across cluster nodes.
• Shift & Rotation Support: Coordinate daytime, evening, and rotating night-shift monitoring schedules to guarantee pipeline SLA compliance and rapid incident response.
• QA & Change Control: Enforce strict operational change controls, ensuring all temporary scripts, data patches, and pipeline logic undergo rigorous QA validation before promotion to live production nodes.
• Data Verification & Audit Readiness: Conduct pre- and post-execution data validations (row count checks, reconciliation scripts) to support financial audits, regulatory reporting, and internal controls.
• Stakeholder Enablement: Collaborate with BI Analysts, Data Scientists, and Business Validation teams to troubleshoot data anomalies, adjust routing logic, and align business rules.
• Qualifications:
