Staff Software Engineer, Directory Accuracy (Health Plans)

H1 • New York, NY

6d • $190,000 - $240,000

About The Position

H1’s Health Plans Software Engineering group builds products that help health plans keep provider data accurate. The Directory Accuracy team owns master data management and client data integration, including the data platform that ingests, matches, and standardizes client data for provider directory accuracy, site feasibility, and healthcare professional credentialing. Its core process includes client entity intake, unique ID assignment, matching against H1’s core data layer, and syncing results back into client feeds and pipelines.

As a Staff Software Engineer, you will design, build, and operate the large-scale data pipelines and services behind products used by health plan and life sciences customers. The role also contributes to customer-facing applications and internal tools that make pipeline data accessible and useful. It is hands-on, with most time spent coding in PySpark, Scala, and SQL, solving data problems at scale, and shipping features for customers and internal teams. You will join a team consisting of a Staff Engineer, a Senior Engineer, and two contractors, and report to the Director of Software Engineering, Health Plans.

The role includes building data pipelines, entity-matching capabilities, data asset management features, APIs, backend services, and self-service tools; integrating clinical and provider data; working directly with enterprise client data; and collaborating with product, design, and adjacent engineering teams. H1 requires candidates to participate in an in-person final interview, which may require travel depending on location.

Requirements

• At least 8 years of software engineering experience, with a strong focus on data engineering and building data-driven products.

• Hands-on experience with entity resolution, record matching, or master data management.
• Experience with data quality, scoring, or validation frameworks.
• Comfort working directly with client data, including messy source files, and onboarding enterprise customers.
• A product-engineering mindset and care for how customers use what you build.
• Clear communication with engineers, product partners, and non-technical stakeholders; ownership of systems end to end and ability to improve an existing codebase.

Nice To Haves

• Full-stack experience or experience building web UIs with a modern framework such as React.

• Contribute to customer-facing and internal applications that help bring new products to market.
• Build self-service internal tools that enable operations, customer success, and other non-technical teams to work with data without engineering help.
• Work directly with messy enterprise client data, debug issues end to end, and make ingestion more reliable and repeatable.
• Integrate clinical and provider data as new products and customers come onto the platform.
• Work with product and design partners to shape features from customer problem through shipped product.
• Improve pipeline performance, reliability, observability, testing, and documentation.
