As part of the Data Engineering & Business Intelligence team, you will be responsible for delivering reliable data products that support analytics, AI data agents, operational intelligence, reporting, and an emerging AI-enabled platform. You will work closely with IT Global, solution build teams, business SMEs, and data governance partners to ensure data products are secure, reusable, explainable, and aligned with enterprise AI / Fabric direction.
Success in this position requires comfort with ambiguity, strong execution discipline, and accountability for building trusted data assets that can be reused across analytics, operational intelligence, and AI-enabled use cases.
Essential Job Functions

• Design, build, and maintain reliable, scalable data pipelines using Python and PySpark on the Microsoft Azure data platform.

• Develop and operate batch and incremental data pipelines leveraging Azure Data Factory for orchestration and Azure Data Lake Storage Gen2 as the primary data store.

• Build and maintain curated lakehouse / gold-layer datasets and semantic-model inputs that support governed operational insights and AI-enabled consumption.

• Independently implement SQL- and Spark-based transformations to produce curated datasets that support enterprise reporting, analytics, AI-enabled insight preparation, and downstream consumption.

• Take ownership of assigned data pipelines and datasets, including monitoring, troubleshooting, performance optimization, documentation, and production support.

• Work with Azure Synapse, Microsoft Fabric / Lakehouse patterns where applicable, and related Azure analytics services to support analytical workloads and data consumption patterns.

• Prepare structured operational data for AI-enabled use cases by documenting business rules, source lineage, data reliability constraints, known quality limitations, and data dictionary definitions.

• Support source visibility, confidence context, and Data Reliability & Trust Indicator integration where applicable so downstream analytics and AI outputs can be understood and trusted.

• Contribute to ontology, taxonomy, semantic model, and data dictionary alignment needed to connect operational context, KPIs, incidents, work orders, and other enterprise data domains.

• Collaborate with business analysts, operations SMEs, data stewards, IT Global, and cross-functional stakeholders to translate requirements into practical, working data solutions.

• Apply established data governance, security, access-control, data classification, and engineering standards to ensure compliant, maintainable, and scalable solutions.

• Identify, document, and route data-quality issues to accountable owners, helping improve source correction rather than masking defects downstream.

• Participate in code reviews, technical discussions, sprint planning, and platform improvement initiatives as an active contributor.

• Proactively identify data quality issues, pipeline risks, platform dependencies, and improvement opportunities, and communicate them clearly in a fast-paced environment.

Duties

• Develop and maintain PySpark notebooks and jobs to ingest, transform, validate, and curate data within the enterprise data platform.

• Build and modify Azure Data Factory pipelines for batch and incremental data ingestion.

• Implement Spark-based transformations that write curated datasets to Azure Data Lake Storage Gen2 and/or Fabric Lakehouse patterns using established folder structures, naming conventions, and governance standards.

• Create and maintain SQL views, tables, lakehouse objects, and semantic-model inputs to support analytics, operational intelligence, and AI-enabled consumption patterns.

• Prepare datasets for Fabric Data Agent / AI agent use cases by documenting business rules, joins, grain, quality limitations, source lineage, and operational definitions.

• Respond to pipeline failures, data validation issues, operational alerts, and data-quality escalations with clear root-cause analysis and practical remediation steps.

• Perform performance tuning of Spark jobs and SQL workloads, including partitioning, filtering, incremental logic, query optimization, and resource-aware design within established architectural patterns.

• Validate data outputs with business partners, operations SMEs, and data stewards, and address defects or discrepancies through documented correction paths.

• Support observability, logging, and auditability practices for data pipelines and AI-consumable datasets where applicable.

• Commit code using Git, follow branching standards, participate in pull request reviews, and support CI/CD ways of working using GitHub, Azure DevOps, or similar tools.

• Update documentation for pipelines, datasets, data contracts, data dictionaries, business rules, and operational runbooks as changes are made.

• Execute assigned backlog items within sprint timelines and raise risks, dependencies, or blockers early.

• Additional duties as assigned by management.
