The role requires strong technical depth to audit, understand, and validate a complex end-to-end data architecture spanning source ingestion through to consumption - and to help deliver the migration of validated workloads to Databricks. This is hands on role and demands the ability to reverse-engineer existing implementations, assess their correctness, and build to an agreed migration strategy., * Azure Synapse Analytics (Pipelines, Spark Pool, Dedicated SQL Pool) * Azure Data Lake Storage Gen2 (ADLS Gen2) * Delta Lake on Azure (Synapse Lakehouse patterns) * Oracle Golden Gate Replication for real-time source integration * Azure Analysis Services and Power BI consumption layer patterns * Deep understanding of medallion architecture: Raw / Harmonized / Conformed / Consumption layers * Strong knowledge of SCD Type 0/1/2, CDC patterns, soft/hard delete, and retroactive change processing * Experience with Synapse SQL Pool - stored procedures, control tables, and data quality validation patterns * Experience with audit, balance, and control frameworks - parameterized, modular pipeline governance at enterprise scale * Familiarity with config-driven and automation-first pipeline patterns (YAML, PySpark, SQL-driven generation from mapping documents) Databricks & Lakehouse * Hands-on experience with Azure Databricks (Delta Live Tables, Unity Catalog preferred) * Strong Apache Spark skills (PySpark / Spark SQL) * Experience migrating workloads from legacy data warehouse or Synapse environments to a Databricks Lakehouse * Ability to re-implement governance and control frameworks natively in Databricks (audit logging, reconciliation, DQ checks) * Experience with Delta Lake features: MERGE, CDC, time travel, schema enforcement Data Engineering & Development * Strong Python and SQL programming skills * Experience with ETL/ELT at scale: denormalization, surrogate keys, directory tables, curated data models * Experience integrating complex data sources: Oracle DB, SQL Server, Azure SQL DB, file systems, Salesforce, APIs * Strong data modelling skills: relational, dimensional, and lakehouse-oriented DevOps & Automation * CI/CD pipelines for data engineering (Azure DevOps / GitHub Actions) * Infrastructure as Code (Terraform or ARM) * Containerization (Docker) * Experience with automated testing frameworks for data pipelines (unit testing, reconciliation-based validation) Nice to Have * Experience with Unity Catalog for data governance and lineage * Familiarity with Azure Purview for data cataloguing and governance * Exposure to real-time and streaming pipelines (Event Hub / Kafka / Kinesis) * Experience with GenAI or ML platform integration (MLOps, feature engineering pipelines) * Familiarity with monitoring and observability tools (e.g., Dynatrace) * Exposure to BI tools (Power BI, Tableau) Experience & Profile * 7+ years of hands-on experience in Data Engineering, including platform migration or re-engineering work * Proven track record working on existing, complex enterprise data platforms - not just building from scratch * Deep knowledge of enterprise data governance patterns: audit trails, reconciliation, data quality controls, SCD versioning * Strong analytical mindset: ability to read existing implementations, identify intent versus defect, and make sound re-engineering decisions * Primarily hands-on, while comfortable contributing to technical design discussions * Strong communication skills - able to engage business, governance, and engineering stakeholders with clarity * Experience working in regulated or enterprise-scale environments (financial services a plus) ## Description * Contribute to the technical assessment and re-engineering of an existing enterprise data platform, spanning all layers from source ingestion through to data consumption * Reverse-engineer, document, and validate existing pipeline logic, data models, transformation frameworks, and data governance controls * Identify gaps, defects, and technical debt across the platform and remediate where implementations are incorrect or sub-optimal * Ensure correctness of data processing patterns including change data capture, slowly changing dimensions, deduplication, and business reconciliation * Implement target-state designs aligned to modern lakehouse principles, ensuring feature parity and business logic fidelity during transitions * Support platform evolution initiatives, including parallel-run phases where multiple implementations operate simultaneously, validating output consistency before cutover * Execute migration of existing workloads to modern data platforms, preserving existing governance and control framework semantics * Re-implement ingestion, transformation, and orchestration pipelines on target platforms, maintaining audit, quality, and reconciliation standards * Collaborate with business, data governance, and architecture stakeholders to validate embedded business rules and data quality requirements * Mentor less experienced engineers, review code and designs, and support decommission planning for legacy components, Sager Electronics is looking for a Power Sales Engineer (PSE) to drive growth within the assigned region by expanding existing customer relationships and developing new business op… + 12 days ago + ## Related Videos -
