Job Description

What you'll be doing:

As a Staff Machine Learning Research Scientist within the Research & Impact team, you will lead foundational ML/AI efforts to deliver a consistent flow of high-quality, insightful research aimed at evidencing and optimizing impact of Crisis Text Line’s service and improving practice, policy and the broader field of mental health support in the US and globally.

You will use Natural Language Processing techniques and Machine Learning models to monitor emerging trends and identify novel signals in our conversations with people in pain so that we can generate near-real-time insights with a potential to improve the lives of people in crisis. As part of a small but nimble team working in collaboration with divisions across the organization, you will research a corpus of over 260 million text messages related to mental health crises to pursue impactful research questions, build ML models to identify new themes, deliver compelling data visualization and actionable insights to amplify Crisis Text Line’s impact for texters, volunteers, and society across languages, cultures, and contexts.

Reporting to the Senior Principal Research Scientist, you will research a unique dataset of more than 8 million crisis conversations since 2013. You will work in close collaboration with all members of the Research & Impact team, as well as with cross-functional partners in data analytics, clinical, volunteer experience, user research, engineering, and product teams. An individual contributor, you will work in close collaboration with all members of the Research & Impact team to ensure equity, diversity, inclusion, and intentional visibilization of multiple identities, especially historically minoritized groups, is an explicit focus for our work.
