Senior Software Engineer - Search

About the role

This role exists to eliminate the frustration of waiting weeks for an appointment only to discover a provider cannot help you. You'll build the search infrastructure and entity resolution systems that power Hinge Select—our integration of digital and in-person MSK care.

Responsibilities

• Audit our current provider and facility discovery architecture, identifying gaps in geospatial search precision and entity resolution accuracy
• Build relationships with product, design, and data engineering teams to understand upstream data sources and downstream user needs
• Deliver your first search optimization—improving relevance tuning or query performance for a high-traffic lookup scenario
• Design and launch geospatial search capabilities using Elasticsearch/OpenSearch (radius, bounding-box, polygon-based queries) that scale to millions of records
• Extend entity resolution pipelines to deduplicate and reconcile provider data across multiple upstream sources, reducing duplicate records by 30%+
• Own the async data ingestion pipeline for a critical data source, ensuring search indexes stay fresh and accurate
• Act as the code repository maintainer for the search and knowledge graph services, setting technical standards and mentoring junior engineers
• Drive technical strategy for the team, balancing tradeoffs between search relevance, latency, and infrastructure cost
• Integrate AI technologies to automate entity matching and improve search personalization, embodying our "Learn-it-all" principle by experimenting with novel approaches

Requirements

• At least 3-4 years of full-time software development experience building production systems at scale
• Bachelor’s Degree (or equivalent) in Computer Science, Engineering or related technical field
• 3+ years of hands-on experience with Elasticsearch or OpenSearch, including index design, mapping configuration, query DSL, and relevance tuning
• Strong understanding of geospatial search (geo_point/geo_shape types, distance-based queries, bounding box filters) and entity resolution (matching, merging, and deduplicating records across disparate data sources)
• Proficiency in modern backend languages (Golang, Python, Java, or similar) and cloud-based services (gRPC, Docker/Kubernetes, AWS)

Preferred Requirements

• Experience building search-driven discovery products (provider directories, marketplace search, location finders)
• Familiarity with healthcare data standards (NPI, FHIR) and identifiers
• Experience with spatial indexing libraries (PostGIS, H3, S2 geometry, Solr spatial)
• Background in record linkage and fuzzy matching techniques (Jaro-Winkler, Levenshtein, probabilistic matching)
• Experience with workflow orchestration systems (Temporal, Airflow, Step Functions) for data pipelines
• Exposure to gRPC service architectures and distributed systems
• Experience in healthcare technology or regulated environments
• AI technology experience for software design and coding
• Mentoring or onboarding junior engineers

Qualifications

• Basic Requirements:
• Experience with AI technologies to automate entity matching and improve search personalization
• Experience with spatial indexing libraries (PostGIS, H3, S2 geometry, Solr spatial)
• Experience with workflow orchestration systems (Temporal, Airflow, Step Functions) for data pipelines
• Experience in healthcare technology or regulated environments
• Experience with AI technologies to automate entity matching and improve search personalization
