About Bask Health

Bask Health is a software platform that enables entrepreneurs, doctors, and healthcare businesses to launch, manage, and grow direct-to-consumer telehealth businesses.

Our platform brings together patient experiences, clinical workflows, pharmacy operations, and commerce tools in one place.

We're an entrepreneurial, product-focused engineering team that values ownership, technical excellence, and building software that solves real problems. Engineers work closely with product teams and company leadership, take features from idea to production, and have a direct role in shaping the platform.

Engineering at Bask is AI-first and builder-led. We use tools like Cursor and Claude Code throughout development while maintaining high standards for reliability, testing, and software quality.

About the Role

We're looking for a Machine Learning Engineer, Search & Discovery to help build intelligent systems that make information easier to find, understand, and use across Bask Health's platform.

Bask Health brings together patient experiences, merchant operations, clinical workflows, pharmacy coordination, and commerce tools. As the platform grows, users and internal teams need efficient ways to locate relevant information, navigate complex workflows, and discover the resources they need.

You'll help develop machine learning-powered search and discovery capabilities that improve how information is retrieved, ranked, and presented across our applications.

This is a hands-on engineering role that combines information retrieval, machine learning, backend development, and modern AI technologies. You'll work with search indexes, embeddings, vector databases, ranking algorithms, APIs, and structured application data to build reliable search experiences.

Your work may include semantic search, hybrid keyword and vector retrieval, intelligent filtering, query understanding, search relevance improvements, and retrieval systems that support AI-powered assistants.

You'll collaborate with product managers, backend engineers, applied AI engineers, and other machine learning specialists to understand user needs and translate them into measurable search improvements.

You'll also help establish evaluation methods for search quality, including relevance testing, ranking metrics, query analysis, and performance monitoring. You'll use real-world usage patterns and evaluation results to identify opportunities to improve retrieval accuracy and user experience.

Because Bask operates in healthcare-related environments, search systems must respect appropriate access controls, data privacy requirements, and tenant boundaries. You'll help ensure users only retrieve information they are authorized to access.

This position emphasizes practical implementation and continuous improvement. You'll work with senior engineers on more complex architectural decisions while independently delivering search features, retrieval services, and ranking improvements.

We're looking for an engineer who enjoys solving information retrieval problems, understands the tradeoffs between search relevance and system performance, and wants to build search experiences that are genuinely useful.

What You'll Do

  • Build and maintain intelligent search and discovery capabilities across Bask Health's applications.
  • Develop search services that retrieve relevant information from approved platform data sources.
  • Implement semantic search using embeddings and vector-based retrieval.
  • Build hybrid search systems that combine keyword matching with semantic retrieval.
  • Develop ranking and reranking approaches that improve search result relevance.
  • Implement query processing, normalization, and understanding capabilities.
  • Build search indexes and data pipelines that keep searchable information accurate and up to date.
  • Develop APIs that expose search and retrieval functionality to other applications.
  • Integrate search capabilities into merchant-facing and internal platform tools.
  • Support information retrieval for AI assistants and retrieval-augmented generation systems.
  • Implement filtering and metadata-based retrieval for structured application information.
  • Develop search functionality that respects user permissions and tenant boundaries.
  • Build automated tests for search behavior, retrieval quality, and ranking performance.
  • Create evaluation datasets that represent realistic search queries and expected results.
  • Measure search relevance using appropriate retrieval and ranking metrics.
  • Analyze search failures, missing results, and low-quality rankings.
  • Improve search quality through experimentation and iterative model or algorithm changes.
  • Evaluate embedding models and retrieval configurations for different use cases.
  • Implement monitoring for search latency, availability, and retrieval performance.
  • Optimize search infrastructure for efficient indexing and query execution.
  • Work with backend engineers to integrate search services into existing application architecture.
  • Collaborate with product teams to identify high-value search and discovery use cases.
  • Develop tools for debugging search results and understanding ranking behavior.
  • Support search-related experimentation and controlled feature rollouts.
  • Improve the reliability and maintainability of search pipelines and services.
  • Participate in code reviews, technical planning, and architecture discussions.
  • Document search configurations, evaluation methods, and implementation decisions.
  • Own assigned search and discovery projects from development through deployment and continuous improvement.
