What We’re Looking For 6+ years of backend/data engineering experience; 2+ years leading teams. Proven success delivering large-scale data migrations or complex ETL projects in production SaaS environments. Deep expertise with Python (Pandas, SQLAlchemy/Django ORM), PostgreSQL , and AWS (S3, RDS, ECS or EKS). Comfort with message queues/workers (Celery, Redis, or similar) and distributed task orchestration. Strong SQL chops—able to profile schemas, diagnose locks, and optimize batch loads. Bonus Points Experience in migrating healthcare EMRs or other regulated PHI data; familiarity with HL7, FHIR, or HIPAA. Hands-on with data-quality platforms (Great Expectations), observability stacks (Datadog, OpenTelemetry), or AI/LLM-driven QA. Familiar with Django, Pydantic, or FastAPI in a monorepo setting. Startup DNA—you iterate rapidly, wear many hats, and enjoy greenfield architecture. About the Role As Senior Migrations Engineering Lead you will own the end-to-end data-migration function—from scoping and tooling through execution and QA—and grow a small but elite team into a disciplined practice. You’ll design repeatable frameworks that ingest messy exports from legacy systems, transform them into our domain model, and land them with zero downtime and forensic-level accuracy. Your work is mission-critical: every smooth cut-over accelerates revenue recognition and strengthens customer trust. What You'll Do Lead & Mentor – Manage 3-6 engineers and data analysts; hire, coach, and set a high technical bar. Architect Tooling – Design scalable ETL pipelines with automated mapping, validation, and rollback. Own the Roadmap – Prioritize migration projects in partnership with Ops, Sales, and Product; drive clear timelines and SLAs. Guarantee Data Integrity – Implement rigorous QA (automated tests, manual checks, reconciliation queries, AI-assisted audits) meeting ≥ 99.9% accuracy targets. Standardize Processes – Create playbooks, templates, and documentation so migrations feel “push-button” to new hires and customers alike. Reduce Risk – Champion observability, HIPAA compliance, PHI encryption, and least-privilege access across tooling and S3 data lakes. Collaborate Cross-Functionally – Align with Customer Success on requirements scoping, Finance on revenue cut-over, and Core Engineering on schema evolution. Continuously Improve – Track metrics (cycle time, defect rate, hours per migration) and drive iterative optimizations. Excellent project-management and stakeholder-communication skills; you keep Sales and Execs un-surprised. Passion for building tooling , automation , and documentation that make future migrations faster and safer. Why Join Us? High Impact – Your work directly accelerates revenue and customer delight. Leadership Opportunity – Build the migrations org from the ground up. Cutting-Edge Stack – Modern Python, Postgres, AI-powered tooling, and cloud-native infrastructure. Mission-Driven – Help private practices deliver better hearing healthcare at scale.
