Senior Data Engineer

Role and Responsibilities

A.DATA MANAGEMENT & TECHNICAL DEVELOPMENT

• Lead the end-to-end management of MS SQL Server, PostgreSQL and DuckDB (DuckLake) database systems, ensuring their stability, scalability and reliability.
• Apply best practices to design and implement high quality, low latency and scalable data solutions and scripts to extract data from source system (SAP ECC6).
• Implement data ingestion strategies (batch and stream) by factoring in source-side constraints and data availability.
• Write, optimize and troubleshoot complex T-SQL queries, stored procedures, views, functions and triggers to support data transformation, loading, and validation logic within MS SQL Server, in line with established coding and naming standards.
• Orchestrate and schedule complex data workflows, ensuring timely and reliable data delivery.
• Implement and manage monitoring solutions to proactively address and prevent performance issues. Monitor daily job statuses and perform troubleshoot and recovery when necessary.
• Develop and maintain staging structures and data models (star and snowflake schemas) within MS SQL Server, ensuring data is structured for efficient querying and reliable analytical consumption.
• Contribute to data quality validation, reconciliation checks, and exception handling across data pipelines, ensuring completeness, accuracy, and consistency of data from source to destination.
• Document pipeline logic, data lineage, transformation rules, table definitions and data dictionary entries, ensuring technical artefacts are kept current and accessible to the team.

B.OPTIMIZATION & PLATFORM TRANSFORMATION

• Deep understanding and assessment of SSIS data pipelines to refactor SQL scripts and migrate them to the new data lakehouse environment.
• Lead in schema design, table optimization (clustering, partitioning, indexing) and other optimization strategies to handle growth.
• Conduct in-depth performance tuning activities, optimizing SQL queries, and database configurations for overall efficiency.
• Identify opportunities to optimize data processes, reduce complexities and costs.
• Participate in technical discussions, debates, peer reviews and knowledge-sharing sessions on topics related to the data warehouse.
• Contribute to the establishment of a data governance framework. Drive the standards and strategy for maintaining a proper and traceable governance model for all end-to-end data assets.

C.BUSINESS PARTNERSHIP & PROJECT MANAGEMENT

• Collaborate with stakeholders to understand business requirements and translate them into technical solutions.
• Assess and evaluate Business Requirement Study (BRS) to ensure that they are thoroughly scoped, covering objectives, business value, data sourcing implications and delivery timeline.
• Serve as the primary liaison for users when it comes to data related issues. Troubleshoot and debug issues arising from user endpoints.

Job Success Requirements

• Minimum of 5 years experience in business solutioning, data / analytics consulting or a data warehouse delivery role, with a track record of partnering directly with business stakeholders.
• Understanding of data warehousing concepts, including dimensional modelling (star & snowflake schemas), slowly changing dimensions (SCD), and staging/ODS design patterns, with the ability to apply these principles to schema design and pipeline architecture decisions.
• Proficiency in MS SQL Server, including database design, T-SQL development (stored procedures, views, functions, triggers), query optimisation, performance tuning, developing and maintaining SSIS packages for data pipelines.
• Good to have: SAP ECC6 or SAP S/4HANA, table formats (e.g. Delta Lake, Apache Iceberg, Apache Hudi, Ducklake), file formats (e.g. Parquet, Avro), data platforms (e.g. Snowflake, Databricks, BigQuery, Synapse), columnar serialization interchange formats (e.g. Apache Arrows)
