Data Engineer Principal_3003

We are looking for an experienced Principal Data Engineer to work hands-on on the re-engineering of an existing enterprise data platform built on Azure Synapse Analytics. 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.

*Key Responsibilities*

• 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

Core Technical Skills

• Azure Synapse & Data Platform Mandatory hands-on expertise with:
• 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)
