Job Description

A bit about this role:

In our mission to take care of every member like they were our own family,, we believe that data is a super power to deliver great service and clinical care. Our Data Platform team designs and builds the infrastructure to support this capability.

In this role, you will write tools to make it easier for our Data Scientists and Engineers to build and deploy scalable, reliable data pipelines, machine learning models, and LLM powered tools. You will help develop and improve a Data Platform built with tools like Snowflake, Apache Airflow, dbt, Kubernetes, Terraform, and all the leading AI labs. You will work on a wide range of impactful projects. Examples of our work include a Change-Data-Capture solution to stream data to Snowflake, a custom Snowflake SQL formatter, an internal Semantic Layer and Data Agent that lets users ask questions about our data in plain language and develop dashboards and analyses. We write most of our tools in Go.

You will be joining a team that values using the right tool for the job with an emphasis on performance, reliability, and maintainability. We also believe in continuously evaluating decisions and striving for improvement as a team. Additionally, we value sharing knowledge, eliminating silos, and collaboration.

Responsibilities will include:

- Design, develop and maintain a robust, scalable data platform that serves analytics, machine learning, and AI workloads

- Build and evolve the infrastructure behind our Semantic Layer and Data Agent, including how LLMs discover, understand, and safely query our data

- Establish evaluation, observability, and quality practices for AI systems that depend on the data platform, so we can measure accuracy and catch regressions

- Ensure data availability, quality, and reliability in the data platform

- Identify areas for improvement with the platform

- Propose new/improved solutions and lead them from design to implementation

- Develop best practices for data modelling, pipelines, and testing

Attributes to success:
