Join a brand-new Data Team – Building from the ground up!

We’re building a brand-new Data Testing team for a major Dynamics 365 transformation — a greenfield initiative that will shape the digital future of one of Europe’s leading organisations - and we’re looking for 4 experienced Data Testers to join the programme focused on data migration, Snowflake, and Microsoft Dynamics 365.

The candidate must possess demonstrated experience in data migration, cloud-based testing, and enterprise platforms such as Snowflake and Microsoft Dynamics 365. A strong background in validating complex data flows and ensuring data integrity is essential for supporting transformation initiatives within financial or enterprise environments.

Key Responsibilities:

• Perform detailed data validation and reconciliation across legacy and target systems, ensuring completeness and accuracy during migration.

• Develop and execute test cases for data, integration, regression, and service-oriented testing, both manual and automated.

• Collaborate with cross-functional teams to define data mapping and transformation rules, supporting successful migration to Snowflake and D365.

• Conduct ETL testing using tools such as Azure Data Factory and SSIS, validating data pipelines and transformation logic.

• Validate entity structures and data loads within Microsoft Dynamics 365.

• Identify and report data anomalies, duplicates, and inconsistencies using analysis tools.

• Maintain clear documentation of test plans, results, and defects using tools like Azure DevOps and JIRA.

• Participate in agile ceremonies and contribute to realistic planning and delivery timelines in hybrid work environments.

Key Requirements:

• Minimum of 5 years QA and software testing experience.

• Strong proficiency in SQL for data interrogation and validation across Snowflake and SQL Server.

• Experience with Snowflake features including virtual warehouses would be an advantage.

• Familiarity with Microsoft Dynamics 365 data structures and Data Service (Dataverse).

• Experience with ETL tools (e.g., Azure Data Factory, SSIS) and cloud-based data testing.

• Knowledge of data migration lifecycle, including source analysis, mapping, transformation, and post-load verification would be an advantage.

• Exposure to test automation scripting.

• Competence in using test management and defect tracking tools (e.g., JIRA, Azure DevOps, Testrail).

• Understanding of data governance and compliance standards (e.g., GDPR).

Nice to Have:

• ISTQB or similar related qualification desirable.

• IT related qualification would be advantageous.
