Job Description

Data Migration Engineer, SQL Server, TSQL

Cresteo

• As a Data Migration Engineer at Cresteo, you'll be more than just a developer; you will be part of transforming the tech industry through our honest, transparent, and people-centric approach. • Your role will be diverse and dynamic. You'll be instrumental in developing and maintaining our software solutions, working with a varied technology stack, and ensuring that our products are functional, efficient, reliable, and scalable.

Job Requirements

  • Deep, hands-on TSQL: complex queries, stored procedures, and functions (not ORM-generated SQL).
  • Proven data migration / ETL experience, especially against legacy or poorly documented source schemas.
  • Ability to reverse-engineer and document undocumented legacy databases.
  • Query performance tuning through execution plan analysis and indexing strategy.
  • Design of incremental, idempotent, re-runnable migration processes.
  • Transaction handling and concurrency control (locking, isolation levels).
  • Data validation and consistency: reconciliation scripts (source vs. target counts, checksums) and a sharp analyst eye for numbers that don't add up.
  • Performance testing under real production volume.
  • Special data types in SQL Server: temporal tables and JSON.
  • Familiarity with jobs/schedulers (SQL Server Agent) or other orchestrators to automate migrations.
  • Experience designing incremental pipelines at scale.
  • Clear and concise communication skills, both written and verbal, to support documentation, issue reporting, and cross-team collaboration.
  • Advanced English level

Benefits

  • 100% Remote
  • USD above-average salaries
  • Profit Sharing Policy
  • Unlimited PTOs after your first year (20 PTOs the first year)
  • Equipment for your setup
  • Great work/life balance
  • Honest, simple, and transparent culture
  • US-based clients and international teams
