Senior Data Platform Engineer

NikoHealth is a rapidly growing SaaS company transforming operations for Durable Medical Equipment and Home Medical Equipment providers. The Senior Data Platform Engineer will own data movement into, out of, and between databases, building reliable migration pipelines, improving onboarding measurement, managing database operations, and planning database engine consolidation.

Responsibilities:

• Get the migration pipeline into version control and under CI, with a dry-run mode and re-runs that don't corrupt anything
• Publish our import contract, so onboarding teams and customers both know what good input looks like before anyone starts
• Put a real measurement on onboarding time-to-live, reported separately for enterprise and small business. We can't currently tell a prospect how long it takes
• Own database configuration, backup, and restore across the fleet, and prove a restore actually works
• Plan the consolidation of our two database engines. Every customer runs both MySQL and PostgreSQL side by side with a live bridge between them, and untangling that is yours to scope, sequence, and execute

Requirements:

• 5+ years in data engineering, data platform, or a closely related role
• Strong SQL, including performance work on large tables, against PostgreSQL or MySQL
• Production ingestion pipelines you built and operated, where idempotency and safe re-runs were a design concern rather than an afterthought
• Experience migrating customer data between systems where the source was messy and the customer was watching
• Python, C# to the level where you own the transform layer outright
• Daily working use of AI coding agents such as Cursor or Claude Code, including the harness around them: tests, project instructions, and a loop you can run again
• candidates must be based in the U.S
• dbt, or a strong opinion about what the ETL layer should look like
• Healthcare claims formats, particularly X12 837 and 835
• A MySQL to PostgreSQL consolidation you've actually done
