About the project

As a Senior Data Engineer within Advanced Analytics, you will design, build, and operate the data infrastructure that powers AI-enabled solutions at global scale. You will own the full data pipeline lifecycle — from ingestion and transformation through to serving data reliably to ML models, AI agents, and analytical consumers. You will work at the intersection of PostgreSQL-based operational data systems and Databricks-based lakehouse pipelines, ensuring data flows are robust, well-governed, and optimised for AI workloads.

Your responsibilities
  • Design and build scalable data pipelines for ingestion, transformation, and serving of structured and unstructured data — supporting both batch and real-time AI workloads.
  • Develop and maintain Databricks-based data processing workflows: Delta Lake table management, PySpark transformations, notebook orchestration, and Unity Catalog governance.
  • Architect and optimise PostgreSQL data models: schema design, indexing strategies, partitioning, query performance tuning, and integration patterns for AI service consumption.
  • Build and maintain data orchestration workflows using Apache Airflow, Databricks Workflows, or equivalent — ensuring reliable scheduling, dependency management, and failure recovery.
  • Implement data quality frameworks: validation rules, anomaly detection, data contracts, and automated alerting on pipeline health and data freshness.
  • Design and manage feature engineering pipelines: transforming raw data into ML-ready feature sets, integrating with feature stores, and versioning feature definitions.
  • Own data integration patterns between operational PostgreSQL databases and the Databricks lakehouse: CDC (Change Data Capture), event-driven ingestion via Kafka, and batch export strategies.
  • Implement data governance standards: lineage tracking, cataloguing, access control, PII handling, data retention policies, and audit logging.
  • Collaborate with ML Engineers to design and deliver data pipelines supporting model training, batch inference, and real-time feature serving.
  • Monitor and operate data infrastructure: pipeline observability dashboards, SLA tracking, incident response, and root-cause analysis for data issues.
  • Champion Claude Code as an active daily tool for pipeline development, SQL generation, data exploration scripting, and documentation.
Our requirements
  • 6+ years of professional data engineering experience, with a strong track record of delivering production data pipelines at scale.
  • Expert-level SQL and strong PostgreSQL expertise: advanced query optimisation, schema design, indexing, partitioning, and understanding of MVCC and connection management.
  • Strong Databricks experience: Delta Lake, PySpark, Databricks Workflows, Unity Catalog, and performance tuning of large-scale Spark Praca.
  • Proficiency in Python for data pipeline development: pandas, PySpark, data validation libraries (Great Expectations or equivalent), and scripting for automation.
  • Experience with data orchestration frameworks: Apache Airflow, Databricks Workflows, or equivalent DAG-based scheduling tools.
  • Solid understanding of data integration patterns: CDC with Debezium or equivalent, Kafka-based event streaming, and batch ingestion strategies.
  • Hands-on experience with data lakehouse architecture: medallion architecture (Bronze/Silver/Gold), Delta Lake ACID transactions, and table optimisation.
  • Experience implementing data quality frameworks and data contracts in production pipelines.
  • Familiarity with Azure data services: Azure Data Factory, Azure Event Hubs, Azure Data Lake Storage, or equivalent cloud-native data tooling.
  • Hands-on proficiency with Claude Code: using it daily for pipeline development, SQL authoring, data exploration, and documentation tasks.
  • Strong communication skills: able to collaborate with data consumers (ML Engineers, analysts, product teams) to understand requirements and deliver reliable data products.
