Principal Data Engineer

Become a part of our caring community

The Principal Data Engineer owns the design and delivery of the NBA platform's data pipelines on the Databricks Lakehouse. This is a hands‑on engineering role. You are expected to be a significant individual contributor building production pipelines every sprint.

You also lead a small team of data engineers and contractors, and are accountable for the quality, reliability, and timeliness of the data that feeds the platform's AI models and decisioning system.

• Pipeline delivery – design, build, and own the Bronze/Silver/Gold lakehouse pipelines that power the NBA platform: member profiles, clinical signals, behavioral data, web clickstream, and socioeconomic features.
• Hands‑on development – actively write and ship production SQL, Python, and Spark code alongside your team; this is not a supervisory role.
• Data modeling – own the Gold layer schema that serves as the canonical member feature set for model training and batch scoring; make design decisions that balance flexibility, performance, and governance.
• Data quality – build and maintain data quality checks, null/sparsity monitoring, and pipeline alerting so the team knows before anyone else when something is wrong.
• External data integration – onboard new data sources (clinical feeds, government datasets, third‑party signals) from raw ingestion through production‑ready features.
• Contractor management – manage data engineering contractors within your pod; set expectations, review work, and hold the team to quality standards.
• Cross‑functional partnership – work closely with the Principal Decision Intelligence Engineer on feature requirements, and with software engineering pods on how data flows into the decisioning system.

• Sponsorship is not available for this role.
• Bachelor's degree in computer science or a relevant field.
• 10+ years of data engineering experience with at least 1–2 years in a tech lead or senior lead capacity.
• Deep hands‑on experience with Databricks and Delta Lake – you have built and owned production pipelines, not just contributed to them.
• Strong SQL and Python skills; comfortable with Spark at scale.
• Experience designing and owning a medallion lakehouse architecture (Bronze/Silver/Gold or equivalent).
• Proven ability to lead a small team or pod through delivery and manage contractor resources.
• Strong data quality instincts – you treat bad data as a production incident.
• Clear communicator – you can explain a pipeline design decision to a data scientist, a product owner, and a compliance officer.
• Comfort using AI productivity tools (Claude, Copilot, or similar) to accelerate development and analysis.
• Strong plus:
  Master’s degree.
• Experience with Databricks Delta Live Tables, Unity Catalog, and Feature Store.
• Familiarity with Kafka‑based event pipelines and real‑time data ingestion.
• Background in healthcare, insurance, or other regulated industries with PHI/HIPAA data handling requirements.
• Experience integrating government or third‑party datasets (CMS, CDC, STARS, or similar).
