Senior Software Engineer - Search

Hinge Health • San Francisco, CA

2d • Hybrid

About The Position

As an early team member building Hinge Select, Hinge Health’s integration of digital and in-person musculoskeletal care, the Senior Software Engineer will develop search infrastructure and entity resolution systems that help patients find appropriate care. The role focuses on geospatial search, data quality, provider and facility discovery, and healthcare search precision, with potential impact for millions of people.

The engineer will audit and improve existing discovery architecture, collaborate with product, design, and data engineering teams, and optimize search relevance or query performance. They will design scalable geospatial search capabilities using Elasticsearch or OpenSearch, extend entity resolution pipelines to reconcile provider data across sources, and own asynchronous data ingestion for a critical data source. Over time, they will maintain the search and knowledge graph code repositories, establish technical standards, mentor junior engineers, guide technical strategy, and explore AI approaches for entity matching and personalization.

Requirements

• Bachelor’s degree or equivalent in Computer Science, Engineering, or a related technical field.
• At least 3 years of non-internship, full-time professional software development experience.
• At least 3 years of hands-on Elasticsearch or OpenSearch experience, including index design, mapping configuration, query DSL, and relevance tuning.
• Strong understanding of geospatial search, including geo_point and geo_shape types, distance-based queries, and bounding-box filters.
• Strong understanding of entity resolution, including matching, merging, and deduplicating records across disparate data sources.
• Proficiency in a modern backend language such as Golang, Python, or Java, or a similar language.
• Experience with cloud-based services and technologies such as gRPC, Docker/Kubernetes, and AWS.
• Ability to communicate complex technical concepts to non-technical partners and document technical decisions clearly.
• Ability to collaborate across teams and take ownership of production systems.

Nice To Haves

• Experience building search-driven discovery products such as provider directories, marketplace search, or location finders.
• Familiarity with healthcare data standards and identifiers such as NPI and FHIR.
• Experience with spatial indexing libraries such as PostGIS, H3, S2 geometry, or Solr spatial.
• Background in record linkage and fuzzy matching techniques such as Jaro-Winkler, Levenshtein, or probabilistic matching.
• Experience with workflow orchestration systems such as Temporal, Airflow, or 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.
• Experience mentoring or onboarding junior engineers.

Responsibilities

• Audit provider and facility discovery architecture and identify 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.
• Improve search relevance tuning or query performance for high-traffic lookup scenarios.
• Design and launch scalable geospatial search capabilities using Elasticsearch or OpenSearch, including radius, bounding-box, and polygon-based queries.
• Extend entity resolution pipelines to deduplicate and reconcile provider data across multiple upstream sources.
• Own an asynchronous data ingestion pipeline for a critical data source and keep search indexes fresh and accurate.
• Maintain the search and knowledge graph services' code repositories, establish technical standards, and mentor junior engineers.
• Drive technical strategy by balancing search relevance, latency, and infrastructure cost.
• Integrate AI technologies to automate entity matching and improve search personalization.
• Take ownership of production code and respond thoughtfully to incidents.

Benefits

• Comprehensive medical, dental, and vision coverage.
• Support for employees and family members with gender-affirming care, family and fertility planning tools, and travel reimbursements if healthcare is unavailable where they live.
• Traditional or Roth 401(k) retirement plan options with a 2% company match.
• Learning and development stipends.
• Discounted company stock through an employee stock purchase plan (ESPP).
• Dog-friendly workplace program at the San Francisco office.
