[Hiring] Senior Data Engineer @HealthFirst

Role Description

The Senior Data Engineer designs, builds, and operates enterprise-scale data solutions on Healthfirst’s AWS Lakehouse platform. They implement batch and streaming data ingestion, ELT/ETL, data quality, and transformation patterns that produce curated, trusted, operations/analytics ready data products.

The role partners with product owners, data modelers, domain stakeholders, and platform teams to translate business requirements into scalable pipelines, reusable frameworks, and clear standards for storing, processing, and moving data. The Senior Data Engineer practices DataOps — CI/CD/CT, automated validation, observability, and Agile delivery — and provides technical leadership through design reviews, mentoring, and engineering best practices.

They own reliable datasets that enable analytics and reporting — not ad-hoc analysis—and ensure pipelines support lifecycle management, resiliency, and governed access across the Lakehouse (raw → refine → publish).

Qualifications

• Bachelor's degree in Computer Science, Information Systems, Engineering, or a related technical field, or equivalent work experience.
• 8+ years of overall IT experience.
• 5+ years of hands-on experience designing and developing enterprise-scale data engineering solutions.
• Strong experience developing scalable data pipelines and reusable frameworks using Python and PySpark.
• Experience implementing enterprise data ingestion, integration, and transformation solutions using AWS Glue, dbt, Apache Spark, or comparable technologies.
• Strong understanding of data warehousing concepts, dimensional modeling, and modern data lake / Lakehouse architectures.
• Experience with cloud platforms such as AWS, Microsoft Azure, or Google Cloud Platform (AWS preferred).
• Strong SQL expertise with relational databases; familiarity with NoSQL databases is a plus.
• Experience with distributed data processing technologies such as Apache Spark, Amazon EMR, or Hadoop-based platforms.
• Experience using Git-based source control and Agile software development methodologies.
• Strong analytical, problem-solving, and communication skills, with the ability to collaborate across technical and business teams.

Requirements

• Design and implement ELT/ETL solutions for batch and streaming ingestion, integration, refinement, and publish patterns on the Lakehouse.
• Develop reusable data processing frameworks and configuration-driven pipelines using Python and PySpark (EMR, Glue, or comparable Spark runtimes).
• Build and maintain scalable orchestration workflows (e.g., Airflow) for production data delivery, including retries, historical loads, and operational runbooks.
• Implement data quality checks, validation frameworks, and monitoring so data products meet defined contracts and SLAs.
• Apply DataOps practices: Git-based development, CI/CD/CT for data pipelines, automated testing, and controlled promotion across environments.
• Contribute to data lifecycle practices (retention, archival, disaster recovery / resiliency considerations) in partnership with platform and governance teams.
• Support platform modernization and cloud migration of legacy data flows into Lakehouse patterns (Iceberg on S3, governed catalog access).
• Collaborate with stakeholders to map technical designs to business processes, non-functional requirements, and consumption needs (Athena, Redshift, APIs, exports, streams).
• Establish and document standards, naming/conventions, and engineering practices; participate in Agile ceremonies and cross-team delivery.
• Provide technical leadership: mentor engineers, conduct design and code reviews, and continuously improve reliability, performance, and cost efficiency.

Benefits

• Medical, dental, and vision coverage.
• Incentive and recognition programs.
• Life insurance.
• 401k contributions (all benefits are subject to eligibility requirements).
