As a Senior Data Engineer, you will play a key role in building, optimizing, and maintaining scalable data architectures and pipelines that power critical healthcare data solutions.

Functions include data architecture, engineering, modeling, integration, optimization, security, and development of cloud-based data solutions. The role designs and delivers scalable, reliable, and high-performing data platforms that support business operations, analytics, and applications. Responsibilities include ensuring data quality, governance, traceability, and compliance; automating validation and monitoring; identifying opportunities to improve business processes; and collaborating with business and technology teams. The role also provides technical guidance, establishes engineering best practices, and supports the successful delivery and operation of enterprise data solutions.

You'll enjoy the flexibility to work remotely * from anywhere within the U.S. as you take on some tough challenges. For all hires in the Minneapolis or Washington, D.C. area, you will be required to work in the office a minimum of four days per week.

Primary Responsibilities

Lead the design and delivery of scalable, governed data engineering solutions, including technical direction, implementation planning, risk management, and production readiness for data products used by business, analytics, and AI/ML stakeholders

Develop and manage robust ETL/ELT pipelines for data ingestion, transformation, and integration from heterogeneous sources, including relational databases, APIs, file shares, and end-user-computing assets

Develop Python and PySpark solutions for distributed data processing, automation, integration, and reusable transformation logic

Optimize data platform performance and cloud consumption through SQL tuning, Spark job optimization, storage format selection, partitioning strategies, cluster configuration, and workload scheduling

Build and optimize workflows on Azure Cloud services and Databricks - including medallion (bronze/silver/gold) layering and orchestrated pipelines - to support enterprise data needs

Migrate business logic embedded in legacy and end-user-computing systems into documented, testable transformation logic over governed tables

Define and implement data quality, validation, reconciliation, and parity testing practices to ensure migrated pipelines are accurate, reliable, auditable, and consistent with the systems they replace

Establish data lineage, ownership, and cataloguing, and define documented rollup and allocation rules where source systems operate at differing grains

Implement security and compliance measures for handling PHI/PII and confidential business data in accordance with HIPAA or similar regulations, including de-identification and masking for controlled sharing

Build and improve CI/CD, version control, and automated testing practices for data pipelines

Implement monitoring, alerting, logging, and operational runbooks for data pipelines to ensure reliability, timely issue detection, incident response, and continuous improvement of production data platforms

Support AI/ML and advanced analytical workflows by provisioning trusted data, scalable infrastructure, and governed consumption patterns for data scientists, analysts, and business partners

Design and publish reusable data products, data services, APIs, and consumption layers that enable downstream applications, analytics platforms, and AI/ML use cases to consume trusted data consistently

Partner with product owners, business stakeholders, architects, data scientists, analysts, and engineering teams to translate requirements into scalable data solutions and communicate technical tradeoffs clearly

Design, develop, and deploy AI-enabled data solutions that address complex business challenges, support responsible AI use, and leverage AI-powered development tools to improve engineering productivity and delivery quality

Mentor data engineers and analysts through design reviews, code reviews, best-practice guidance, and support for improving team delivery quality

You'll be rewarded and recognized for your performance in an environment that will challenge you and give you clear direction on what it takes to succeed in your role as well as provide development for other roles you may be interested in.
