Headway’s mission is a big one – to build a new mental health care system everyone can access. We’ve built technology that helps people find great therapists with the first software-enabled national network of providers accepting insurance. 

1 in 4 people in the US have a treatable mental health condition, but the majority of providers don’t accept insurance, making therapy too expensive for most people. Headway is building a new mental healthcare system that everyone can access by making it easy for therapists to accept insurance and scale their practice. 

Headway was founded in 2019. Since then, we’ve grown into a diverse, national network of over 60,000 mental healthcare providers across all 50 states who run their practice on our software and have served over 1 million patients. We’re a Series D company with over $325m in funding from a16z (Andreessen Horowitz), Accel, GV (formerly Google Ventures), Spark Capital, Thrive Capital, Forerunner Ventures and Health Care Service Corporation.

We want your time here to be the most meaningful experience of your career. Join us, and help change mental healthcare for the better.

About the Team

Our Ranking team’s mission is to help every patient find the right provider for their needs. We are building the matching system that powers this connection, from search and discovery to ranking and personalization. Our goal is to combine cutting-edge machine learning with a deep understanding of patient and provider experience.

About the Role

We’re looking for a Staff Data Scientist to advance how we connect patients with the right therapist. You will evaluate the product experience and underlying ML systems that help patients find their best-fit clinician. Your research will power our understanding of the matching performance and help us prioritize experiments to drive improvements. You will work closely with the engineering teams to turn your findings into concrete changes to the patient experience. This is an opportunity to bring both scientific rigor and empathy to a problem that truly matters — helping people access effective, personalized mental healthcare.

 

What You’ll Do

• Analyze and evaluate the performance of our search and ranking systems using offline and online metrics
• Develop frameworks to measure relevance, conversion signals, and long-term patient outcomes
• Conduct exploratory research to identify new search and ranking signals, along with opportunities for personalization
• Partner with ML engineers to translate research findings into production-ready models and features
• Collaborate with product, clinical, and engineering teams to define success metrics and guide experimentation.
• Clearly  communicate findings, recommendations, and business implications to both technical and non-technical stakeholders

What We’re Looking For

• PhD or Master’s degree in Statistics or a related quantitative field.
• 3–6 years of experience in data science, applied machine learning, or a related field.
• Strong proficiency in Python, SQL, and experimentation/causal inference techniques.
• Familiarity with ranking, search, or recommendation systems (e.g., relevance modeling, click modeling, LTR methods).
• Comfort with ambiguous, open-ended research questions and the ability to translate findings into actionable insights.
• Excellent communication skills — able to explain complex ideas simply and build trust across teams.
• Passion for improving access to mental health care and advancing outcomes for patients.
  
  

Nice to Have

• Experience with large-scale search or recommendation evaluation frameworks (e.g., NDCG, MAP, offline/online A/B testing).
• Familiarity with fairness or bias evaluation in ML systems.
