We are looking for a Senior Data Engineer to join our lean, high-impact Data & Analytics team (currently a data analyst and a data engineer). You will own and evolve the data platform that powers clinical operations, business intelligence, and AI initiatives. This is a hands-on, full-stack data role: you will build and maintain pipelines, design analytical data models, contribute backend application code, and help the team adopt modern AI-assisted development practices.

This is not a traditional analytics or BI role. We need a strong software engineer who happens to specialize in data. Our entire DWH, ETL, and reporting stack is built in Python on AWS, so deep Python development experience is essential. The ideal candidate can write production-quality Python and SQL with the same rigor as any backend engineer, while also being comfortable configuring a Looker explore, building an AWS Glue job, or contributing Java code where needed.

You thrive in a startup environment where ownership is broad and velocity matters.

• Design, build, and maintain scalable data pipelines and ETL/ELT workflows in Python using AWS Glue, Apache Spark, Airflow, or equivalent orchestration tools.
• Write production-grade Python code for DWH logic, reporting jobs, data transformations, and internal tooling, following software engineering best practices (testing, code review, CI/CD).
• Develop and optimize analytical data models (dimensional, OBT, or hybrid) that serve self-service BI and advanced analytics use cases.
• Build and maintain dashboards, explores, and semantic layers in Looker and/or Tableau; serve as the analytics infrastructure owner ensuring data quality and governance.
• Contribute backend application code in Java (Spring Boot) or Python to support data-intensive features, API integrations, and internal services.
• Champion modern AI coding practices across the data team, leveraging tools like Git Hub Copilot, Claude, Cursor, or similar AI-assisted development environments to accelerate delivery and code quality.
• Author and maintain comprehensive SQL assets (stored procedures, views, complex queries) across Redshift, Aurora/MySQL, and Athena.
• Operate and optimize AWS data infrastructure including Glue, S3, Redshift, Cloud Formation, Cloud Watch, IAM, and Athena.
• Collaborate closely with clinical operations, product, finance, and engineering teams to translate business questions into reliable, well-documented data products.
• Implement data quality frameworks, monitoring, alerting, and incident response processes for the data platform.
• Contribute to the architecture and data strategy for AI/ML features, including data prep, feature engineering, and model monitoring.
• Mentor the existing data analyst and data engineer; help establish team standards, code review practices, and documentation norms.

• 10+ years of professional experience in data engineering, analytics engineering, or a hybrid data/backend software engineering role.
• Strong software engineering background: this role requires someone who can write, test, debug, and ship production code, not just query data.
• Expert-level Python: deep experience building production data pipelines, ETL logic, and reporting systems in Python.
• Expert-level SQL: window functions, CTEs, recursive queries, query optimization, and performance tuning at scale.
• Hands-on experience with AWS data services, specifically Glue, S3, Redshift, Athena, Cloud Formation, Cloud Watch, and IAM.
• Experience with MySQL/Aurora in a production environment.
• Hands-on experience building and operating data pipelines with AWS Glue, Spark, dbt, Airflow, or comparable frameworks.
• Deep experience with at least one modern BI platform. Looker (LookML) strongly preferred;
  Tableau also valued. Should include semantic modeling, dashboard…
