Job Description

This role involves planning, executing, and validating data migration processes across multiple environments. You will play a critical role in ensuring data accuracy, integrity, and consistency while migrating from legacy systems to new platforms. Your expertise in testing methodologies, data validation, and migration tools will drive seamless transitions with minimal disruption to business operations.

Job Responsibility

  • Design and develop comprehensive migration test plans, including test strategies, scenarios, and scripts to validate data migration integrity
  • Ensure all data is accurately and completely migrated. Develop SQL queries or scripts to compare source and target data sets, checking for consistency, quality, and completeness
  • Execute test cases across migration stages, including initial data load, incremental data load, and final validation before go-live
  • Identify, document, and track defects or inconsistencies in data, collaborate with cross-functional teams to resolve issues, and validate fixes to ensure a high-quality migration
  • Work closely with infrastructure and database teams to set up testing environments that mirror production conditions and contain the necessary data for testing
  • Identify potential risks in migration plans and suggest risk mitigation strategies
  • Create automated scripts where feasible for large data comparisons and validations. Familiarity with testing frameworks, SQL, and relevant ETL or migration tools is preferred
  • Document testing processes, outcomes, and issues, providing regular reports and analysis to stakeholders on migration test progress, results, and risks

Requirements

  • Minimum 7 years of experience in migration testing or data validation roles, preferably involving large-scale data migrations
  • Proficiency in SQL for data validation and comparison
  • Experience with data migration tools (e.g., AWS DMS, Informatica, Talend, or similar)
  • Familiarity with ETL processes, data transformation, and data quality principles
  • Knowledge of test automation tools and frameworks, especially for data migration (e.g., Python scripting for automation, Selenium, or Robot Framework)
  • Strong problem-solving and analytical skills for identifying data discrepancies and their root causes
  • High attention to detail, especially with respect to data integrity and accuracy
  • Excellent verbal and written communication skills, with the ability to communicate complex findings clearly to technical and non-technical stakeholders
  • Ability to work in cross-functional teams, liaising with developers, database administrators, business analysts, and project managers

Nice to have

  • Relevant certifications in testing (e.g., ISTQB) or data management (e.g., Certified Data Management Professional (CDMP))
  • Familiarity with cloud environments, especially AWS, Azure, or Google Cloud, is a plus
  • Experience with scripting languages such as Python, Bash, or PowerShell for data manipulation and automation

What we offer

  • Impactful Work: Be part of a critical function that ensures successful transitions and mitigates risk in high-impact projects
  • Growth Opportunities: Opportunity to enhance your skills in data migration, testing automation, and cloud data management
  • Collaborative Culture: Work alongside talented professionals in a supportive, team-oriented environment
