We are forming a geographically distributed but cohesive and high-performing team of inquiring minds; we plan our teamwork around flexible schedules and other personal needs. You will be part of a group of innovators who will help drive the change for healthcare consumers.

We are looking for a seasoned software engineer or data scientist who is interested in working on complex problems related to search technology in healthcare. This individual should be able to take the lead on projects that may require the coordination of several internal teams to implement. We expect this leader to contribute to the design of our search data platform, collaborate with other platform leaders to create efficient solutions and deliver state-of-art production systems that are easy to maintain. After a period of learning, you may gravitate toward our ingestion platform or concentrate on search engine indexing and move toward ranking and relevance research.

You’ll enjoy the flexibility to telecommute* from anywhere within the U.S. as you take on some tough challenges.

Primary Responsibilities:

  • Participating in the engineering life-cycle, including designing high-quality ML infrastructure and data pipelines, writing production code, conducting code reviews, and working alongside our infrastructure and reliability teams
  • Understand, connect, and synthesize data to operate in ambiguity. Lead the way to an innovative solution.
