Software Developer Etl - Senior

SCOPE:

The Office of the Public Guardian and Trustee (OPGT) requires a Senior Software Developer – ETL to perform data migration activities from the existing OPGT legacy applications to the new Dynamics 365 OPGT solution and data warehouse/lakehouse.

DELIVERABLES:

As a member of the data migration team, you will be responsible to migrate the data from the existing OPGT legacy applications to the new Dynamics 365 OPGT solution and the new data warehouse/lakehouse. A high-level list of deliverables for the data migration team follows:

• Data Migration Strategy and Execution: review the present migration strategy that outlines the overall approach, sequence, and timeline for migrating the data from the legacy application to Dynamics 365 using a delta-load approach; execute the migration plan efficiently, managing data transfers and ensuring minimal disruption to ongoing operations;
• Data Mapping and Transformation: map the data elements from the legacy application to the corresponding entities and fields in Dynamics 365 CE, F&O and Data Lakehouse. Handle necessary data transformations, ensuring compatibility and consistency between the legacy data and the target system;
• Documentation: document the entire data migration process, including data mapping rules, transformation logic, migration scripts, and any specific configurations;
• Data Cleansing and Validation: cleanse and validate the extracted data to ensure its accuracy, completeness, and consistency. Help with identifying and resolving data quality issues, performing deduplication, and applying business rules to ensure the integrity of the migrated data;
• Data Analysis: analyze the existing data in the legacy applications, understand its structure, quality, and relationships and help in designing an appropriate migration strategy.
• Ongoing Support: provide post-migration support, analyze and address data-related issues or questions; help optimize data management processes in the new environment;
• Data Testing and Quality Assurance: conduct thorough testing to verify the accuracy and integrity of the migrated data; define test cases, perform data reconciliation, and address any issues or discrepancies that arise during the testing phase; develop KPIs to report on the progress, completeness and quality of the data migration effort;
• Data Extraction: help extract the required data from the legacy application, develop and implement extraction processes to retrieve data from various sources, such as databases, files, APIs, or other relevant legacy systems;
• Data Lakehouse: help expand the current data lakehouse implementation and help build a gold layer for reporting; conduct data analysis and profiling; develop data transformation and cleansing pipelines; implement data integration and harmonization;

MANDATORY REQUIREMENTS:

• 5+ years of proven working experience in an ETL role; strong understanding of ETL principles, including data extraction, transformation, and loading processes; knowledge of common ETL design patterns. Understanding of data pipeline architectures, Azure workflow orchestration tools, and concepts related to data ingestion, transformation, and movement.
• Experience with continuous integration/continuous deployment (CI/CD) processes around DevOps, data workflows, Synapse workspaces.
• Proficiency in scripting languages like Python, experience with Azure-specific scripting using PowerShell or Azure CLI.
• Strong SQL skills and experience working with Azure SQL Databases and Dataverse; good understanding of Azure storage concepts and technologies.
• Experience with SSIS, SSRS, PowerBI
• Proficiency in Azure Data Factory, Azure Synapse workspaces, PolyBase, including knowledge of pipeline creation, data flows, integration runtimes, triggers, and monitoring.
• Expert proficiency with data manipulation languages (T-SQL, PL/SQL), data definition languages, physical database design, data modeling, query performance analysis & tuning
• Knowledge of integration technologies commonly used with Dynamics, such as DataVerse / Common Data Service (CDS), Data Entities, and APIs.
• Familiarity with data warehousing concepts and experience working with Azure Synapse Analytics or similar platforms for building and managing large-scale data warehousing/lakehouse solutions.
