Come make an impact on the communities we serve as you help us advance health optimization on a global scale. Join us to start Caring. Connecting. Growing together.
Own the design, build, and operation of reliable data pipelines and curated data products that power analytics, reporting, and downstream applications.
Set engineering standards for data quality, observability, security, and cost/performance across the data platform.
Primary Responsibilities:

• Design and implement scalable ETL/ELT pipelines (batch and/or streaming) with strong guarantees: idempotency, incremental processing/CDC, backfills, and schema evolution
• Model and publish well-defined datasets in a cloud data warehouse/lakehouse (dimensional modeling, partitioning/clustering, performance tuning)
• Build orchestration workflows (Airflow/Dagster/Prefect) with robust dependency management, retries, SLAs, and operational runbooks
• Establish data quality and testing practices (unit/integration tests for transformations, validation rules, anomaly detection, and data contract checks)
• Implement end-to-end observability (structured logging, metrics, lineage/metadata where available, alerting on freshness/volume/drift/failure modes)
• Partner with Analytics, Product, and Engineering to translate requirements into maintainable data products and clear dataset contracts/documentation (e.g., data dictionaries)
• Apply security and governance controls for sensitive data (PII/PHI), including least-privilege access, auditing, and retention policies
• Drive CI/CD and infrastructure-as-code for data workloads (Git-based workflows, automated checks, environment promotion)
• Mentor engineers, review designs/code, and lead incident response and postmortems for data reliability issues
• Comply with the terms and conditions of the employment contract, company policies and procedures, and any and all directives (such as, but not limited to, transfer and/or re-assignment to different work locations, change in teams and/or work shifts, policies in regards to flexibility of work benefits and/or work environment, alternative work arrangements, and other decisions that may arise due to the changing business environment). The Company may adopt, vary or rescind these policies and directives in its absolute discretion and without any limitation (implied or otherwise) on its ability to do so

Required Qualifications:

• BTech / MCA
• Proven experience building and operating data pipelines at scale (incremental loads, CDC patterns, backfills, late-arriving data handling)
• Experience with workflow orchestration (Airflow/Dagster/Prefect) and operational ownership (SLAs, on-call readiness, runbooks)
• Experience with CI/CD and IaC (Terraform/CloudFormation) for reproducible, auditable deployments
• Hands-on experience with a modern cloud data stack (AWS/GCP/Azure) and a warehouse/lakehouse (e.g., Snowflake/BigQuery/Redshift/Databricks)
• Familiarity with distributed processing (Spark or equivalent) and performance debugging (partitioning, shuffles, skew)
• Solid understanding of data modeling (star/snowflake, SCDs) and dataset lifecycle management
• Solid fundamentals in security/compliance for data (encryption, access control, auditing; handling PII/PHI)
• Proven advanced SQL: complex joins, window functions, query optimization, and warehouse performance tuning
• Proven solid programming skills in Python (preferred) with production engineering practices (packaging, testing, linting, code review)

Preferred Qualifications:

• Experience in Streaming/event-driven architectures (Kafka/Kinesis/Pub/Sub), exactly-once/at-least-once tradeoffs, watermarking concepts
• Experience in Data governance/metadata tooling (catalogs, lineage, ownership) and data contract frameworks
• Domain experience in healthcare/claims/EHR data (or other regulated environments) and associated compliance practices

What success looks like (first 3-6 months)

• Critical pipelines are reliable, observable, and meet freshness SLAs with clear ownership and runbooks
• New/updated datasets ship with quality checks and documentation, and changes are managed via versioned contracts
• Platform cost/performance improves measurably through optimization and better operational discipline

At UnitedHealth Group, our mission is to help people live healthier lives and make the health system work better for everyone. We believe everyone-of every race, gender, sexuality, age, location and income-deserves the opportunity to live their healthiest life. Today, however, there are still far too many barriers to good health which are disproportionately experienced by people of color, historically marginalized groups and those with lower incomes. We are committed to mitigating our impact on the environment and enabling and delivering equitable care that addresses health disparities and improves health outcomes - an enterprise priority reflected in our mission.
