Through our website, blog, and app—filled with meditations, sleep stories, music, movement, and more—we’re redefining what mental care looks like in 2021 and beyond. With over 100 million users worldwide, 100,000 new users daily, and our growing partnerships with major companies, we’re having a positive effect on more and more people each and every day. And while the heart of Calm is digital, we are growing and expanding offline with a variety of products and services to help deliver on our mission of health and happiness, the world over. 

What We Do:

Our mission to help millions of users learn to meditate and sleep better through a personalized experience.

In this role, you will also work to increase the reliability and trustworthiness of our data by identifying data quality issues and the sources and magnitudes of such problems.

  • Provide reasonable project timeline estimates and communicate regularly with stakeholders on project status
  • Stay up-to-date with the latest machine learning literature and tools
  • Prioritize projects with a business mindset and user empathy

Who You Are: 

  • 5+ years of industry experience in developing and productionalizing machine learning models
  • Advanced python and SQL skills
  • Build software that integrates machine learning products into the Calm app
  • Develop feature engineering data pipelines on large datasets
  • Familiar with the modern MLOps Stack: feature store, model registry, CI/CD, model monitoring

  • Great technical communicator
  • Strong attention to detail
  • Strong product and architectural instincts
  • Experience in at least one of these areas:
