This is a client-facing, hands-on role for someone who is naturally curious, analytical, and motivated to solve complex data challenges. The Data Migration Analyst will contribute directly to multiple conversion engagements while helping Nymbus develop reusable migration standards, documented conversion patterns, and AI-assisted tools that improve speed, accuracy, and scalability. The successful candidate will be comfortable performing detailed conversion work while also identifying opportunities to automate manual processes, improve validation workflows, and advance the way data migration is delivered at Nymbus.
