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.

What You’ll Do

• 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

Tech Stack

• Languages & Frameworks: Python (Django, FastAPI), SQL

• Orchestration & Compute: Prefect, Ray, Apache Spark

• Data Storage: Postgres, Snowflake, dbt, Snowflake Shares

• Cloud Platform: Azure (Blob Storage, Data Factory, Azure Functions)

• Testing & CI/CD: Pytest, GitHub Actions, Databricks (for test pipelines)

• Observability: Metaplane or similar data observability tooling

• Nice-to-Have: Apache Iceberg, Airbyte, familiarity with GenAI/LLM concepts (e.g., RAG, embeddings, vector stores)

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

• Experience with healthcare or life sciences data is a strong plus

Work Environment

• Location: Bangalore (Hybrid – 3 days/week in office)

• High-ownership, collaborative engineering culture

• Lean, fast-moving team solving tough technical and domain problems

• Backed by McKesson, one of the world’s largest healthcare companies
