Job description

Software Mind develops solutions that make an impact for companies around the globe. Tech giants & unicorns, transformative projects, emerging technologies and limitless opportunities – these are a few words that describe an average day for us. Building cross-functional engineering teams that take ownership and crave more means we’re always on the lookout for talented people who bring passion and creativity to every project. Our culture embraces openness, acts with respect, shows grit & guts and combines cooperation with enjoyment.

Job Description

Project – the aim you’ll have

Join a large-scale data migration programme run by an international software provider operating in a regulated, audited sector. You will work in a small, senior delivery team alongside the client’s own engineering squads, moving millions of records from a legacy system into a modern Azure estate. Strict reconciliation standards, genuine accountability for data integrity, and direct contact with the client’s technical leadership.

Role – how you’ll contribute

• 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

Qualifications

Expectations – the experience you need

• 3+ years delivering data migration or ETL development 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 across European and APAC time zones
• Willingness to undergo background screening, including a criminal record check

Additional skills – the edge you have

• Microsoft certification, ideally DP-203 Azure Data Engineer Associate
• ITIL Foundation v4, or willingness to certify (at our cost)
• Experience in a regulated, audited sector such as financial services, public sector or healthcare
• Experience with change data capture and keeping systems in sync during a parallel-run period
• Exposure to Databricks, Snowflake or dbt
