Job summary

Software Mind is seeking an experienced data migration/ETL engineer to join a large-scale Azure data migration programme. You will work in a senior delivery team, moving millions of records from a legacy system into Azure SQL, with strict reconciliation standards and direct client contact.

You will design, build and run ETL pipelines, profile source schemas, document models, and implement validation and cutover support, while following ITIL change and release processes.

Qualifications

• 3+ years delivering data migration or ETL on enterprise or high-stakes systems.
• Strong T-SQL and hands-on experience with Microsoft SQL Server, including SSIS.
• Practical experience with Azure SQL Database and the surrounding Azure data services (Data Factory, Azure DevOps).
• Demonstrable data validation and reconciliation work: you can explain how you proved a migration was correct, not just that it ran
• Comfort working from incomplete documentation, using schema discovery and data profiling as a first step
• Experience handling JSON and XML payloads held inside relational structures
• English at C1 or above, with daily contact with international stakeholders

Responsibilities

• Design, build and run ETL pipelines migrating data from legacy SQL Server databases into Azure SQL
• Profile and reverse-engineer source schemas where documentation is incomplete, and document the model you reconstruct
• Build validation and reconciliation logic that proves completeness and correctness ahead of the initial load and every delta load
• Work with the Business Analyst on data mapping, transformation rules and the agreed data dictionary
• Execute migration rehearsal runs and support the cutover
• Follow ITIL-aligned change and release management for every production change
• Diagnose and resolve production data incidents, and contribute to root cause analysis and permanent fixes
• Maintain technical documentation for the migration components and hand it over at the end of the engagement
