About Ginger

Ginger is reinventing mental healthcare by coupling data science and virtual delivery to provide immediate, personal support for anyone. Care from our on-demand mental health system is delivered through the Ginger app, available on iOS and Android, where members can conveniently connect with Ginger’s team of behavioral health coaches - 24/7, 365 days a year. For those in need of additional support, a therapist or psychiatrist can be added to their care team. Over half a million people have access to Ginger through leading employers, health plans, and other partners. The World Economic Forum has identified Ginger’s AI technology as a Technology Pioneer, and the company was recognized as one of the top 10 Most Innovative Companies in Healthcare by Fast Company.

Job Description

We are looking for an experienced engineering manager with outstanding expertise in applied Machine Learning (ML) and Natural Language Processing (NLP) to lead the ML team in delivering on our team's mission of expanded quality and scalability at Ginger. The ML team uses our large and unique datasets to model, understand, and predict emotional and cognitive state, care quality, factors driving optimal well-being and many other essential signals. 

Machine learning (ML) in the Data Science team moves the needle for Ginger by building two essential types of magic:

  • Products developed, launched and supported which drive scalability, introduce science-fiction-like efficiency and increase quality of care to superhuman levels previously unseen.
  • Deep multi-dimensional actionable understanding of our members, caregivers, and treatments unlocked in the form of features generated, stored and surfaced by our ever-growing state of the art AI engine.

As our Machine Learning Manager, you will run ML at Ginger, leading our innovative team to algorithmically leverage the many dimensions of our data to better serve our members, caregivers and internal teams. Partnering closely with both our caregiver and member app product teams, you'll work synergistically to ideate projects and deliver value to our customers through the use of applied machine learning. You will also lead discussions within your team and the whole DS team to identify new and large opportunities that will expand our capabilities.  We are looking for someone who will thrive in a fast-paced environment and can be hands-on when needed.
