About Us
At Compile (a McKesson company), we’re transforming fragmented healthcare data into powerful intelligence that drives real-world impact — from mapping patient journeys to optimizing go-to-market strategies for life sciences.
We're building a modern, scalable, and secure data platform that powers data products across the organization. As a Principal Engineer, you'll be the hands-on technical leader driving the design and development of this foundational platform.
If you’re passionate about clean architecture, distributed systems, and solving real-world data challenges — especially in healthcare — this is your opportunity to make a deep impact.

Architect and lead development of a reusable, scalable data platform framework
Design robust ETL/ELT pipelines for structured and semi-structured healthcare data
Build APIs and internal tools using Django, focused on performance and maintainability
Use Prefect for orchestration, and Ray or Spark for distributed compute
Leverage Databricks for testing and validation of data pipelines (not for primary compute)
Enforce data quality, observability, and reliability using Metaplane or similar tools
Integrate and manage data across Postgres, Snowflake, and Snowflake Shares
Optimize for scalability and performance in a cloud-native Azure environment
Mentor engineers and collaborate with product, data, and platform teams

What We’re Looking For
15+ years of experience in data engineering, platform architecture, or backend systems
Proven experience designing and building modular data infrastructure
Hands-on expertise with ETL frameworks, orchestration tools (Prefect), and distributed compute (Ray/Spark)
Strong experience in Django-based API development
Deep understanding of data modeling, warehousing, and pipeline reliability
Experience with Azure cloud services and managing large datasets across Snowflake and Postgres
Familiarity with data observability and monitoring tools (e.g., Metaplane)
Nice-to-have: Exposure to GenAI/LLM systems such as vector search or RAG pipelines
