A Brief Overview

Our Consumer Analytics team does a ton of personalized outreach and experimentation at impressive scale: >100M messages per year. These messages educate members on truly meaningful things like staying adherent to medications, avoiding admissions to hospitals, and improving overall health (not about getting people to click on ads!).

We do this through a combination of rules and ML models that identify who to target, an experimentation platform that we’ve built that allows complex journeys and test designs, and a combination of channels and vendors that deliver messages including SFMC. We do this hand in hand with our data engineering and marketing partners.

This role is part of a team that is tasked with making this platform and system more automated, more insightful, and faster. Think things like building systems for more automated targeting, embedding our experimentation platform with methods of measuring interventions automatically and optimizing across variants automatically, and building methods of orchestration that automatically optimize for ROI. The Principal Data Scientist role will serve as a technical mentor, someone to guide our technical strategy, and a builder.

  • Develop an understanding of how interventions work and are measured at CVS
  • Work with a multi-disciplinary team of data scientists and data engineers to collaborative build a vision and do development work for the platform.

  • Has experience being a data scientist and developing software
  • Loves innovating and working on small teams that get stuff done and have a lot of autonomy

For this role you will need Minimum Requirements

  • Mastery of problem solving and decision-making skills
  • Mastery of collaboration and teamwork
  • Mastery of growth mindset (agility and developing yourself and others) skills
  • Mastery of execution and delivery (planning, delivering, and supporting) skills
  • 10+ years work experience

Programming/Technical skills required

  • Hands-on experience with cloud computing (Google Cloud, AWS, etc.)
  • Strong theoretical and hands-on experience with statistics and machine learning
  • Strong understanding of version control (i.e. git)
