Principal Data Engineer

Overview

The Principal Data Engineer is a member of the Data Platform team, reporting to the Director of Machine Learning Engineering and Data. The Data Platform team is responsible for executing the data strategy for the organization, ensuring high-quality external data is ingested into the Lakehouse and realized in powerful insights for internal and external customers, while ensuring ML/AI, BI and customer success teams have the data they need to develop and train their models, build insightful dashboards and design semantic layer.

Responsibilities

• Own the technical strategy and roadmap - Own the vision, architecture, and roadmap for the CodaMetrix data platform, ensuring scalability, reliability, regulatory alignment, and operational excellence. Lead key technology decisions, disaster recovery design, architecture reviews, and data engineering standards across teams.

• Platform Engineering at Scale - Design, build, and maintain scalable streaming and batch data platforms Databricks using PySpark, Unity Catalog, Delta Lake, and Structured Streaming. Own Terraform-based infrastructure across environments, including jobs, catalogs, schemas, permissions, compute policies, volumes, and external locations.

• Build Jenkins CI/CD workflows for automated testing, tagging, and deployments, while optimizing training pipelines, materialized views, retention policies, and production performance.

• Data Governance & Security - Implement and evolve least-privilege access controls across Databricks using Unity Catalog grants, YAML-driven group policies, and schema-level restrictions. Ensure HIPAA and SOC 2 compliance through PHI masking, audit logging, environment-level data segmentation, user provisioning, compute policies, and cost attribution.

• Cost Optimization & Operational Excellence - Drive platform cost reduction through compute policy tuning, serverless optimization, reserved pools, materialized view improvements, and remediation of underutilized resources. Monitor Databricks/AWS spend (using tools like CloudZero and AWS Cost Explorer), own cost attribution and budgeting, resolve production incidents, and maintain runbooks to ensure platform SLAs for uptime and performance.

• Cross-Functional Enablement & Mentorship - Enable ML, BI, Analytics, DevOps, and customer success and implementation teams with training data pipelines, model-ready datasets, feature store architecture, optimized views, dashboards, Tableau refreshes, infrastructure changes, and tenant onboarding. Mentor engineers through code and design reviews, establish quality standards, and serve as a subject matter expert for data platform engineering across the organization.

Requirements

• A degree in Computer Science or a related field (Bachelor's, Master's, or Ph.D.), or an equivalent combination of education and demonstrable professional experience

• 8+ years of data engineering experience with progressive responsibility

• 5+ years hands-on experience with the Databricks platform (Unity Catalog, Delta Lake, Structured Streaming, Spark SQL, cluster management, platform administration)

• Expert proficiency in PySpark and Python; working knowledge of Scala

• Expert experience with Terraform for infrastructure-as-code (state management, modular structures, multi-environment deployments, YAML-driven configuration)

• Expert experience with Apache Kafka / AWS MSK (streaming ingestion, SASL/IAM auth, topic management, cluster migrations)

• Deep understanding of medallion/lakehouse architecture patterns (bronze/silver/gold, SCD2, materialized views, slowly changing dimensions)

• Proven track record building and maintaining CI/CD pipelines (Jenkins, GitHub Actions) for data platform deployments

• Strong AWS experience (S3, IAM, Secrets Manager, VPC/Private Link, cross-region replication)

• Demonstrated ability to operate in a HIPAA-regulated environment with PHI handling requirements

• Experience with disaster recovery architecture — cross-region replication, failover procedures, read-only replicas

• Experience using AI tools (e.g., Claude, Gemini, Codex) and agentic workflows to augment design, development, and testing processes

Huge Plus

• Prior experience working with healthcare data, such as medical claims, electronic health records (EHR), or billing code systems (ICD-10, CPT)

• Familiarity with healthcare data standards like HL7 or FHIR is highly desirable
