Senior Data Scientist

New York, New York, United States; San Francisco, California, United States; Seattle, Washington, United States

1 in 4 people in the US have a treatable mental health condition, but most providers don't accept insurance, making therapy too expensive for most people. Headway’s mission is to fix this by building a new mental healthcare system everyone can access. We started by solving the biggest barrier to care: insurance. The admin work - credentialing, claims, payment reconciliation - is a nightmare. We've automated that.

But we're going further. Over 70,000 providers across all 50 states run their practice on our software, serving over 1 million patients. We are building the best tools for therapists to run their entire practice, reimagining the experience of finding a therapist, and investing in the platform foundations to enable this at scale. We aren't just a billing layer; we are becoming the platform where care actually happens.

We're a Series D company with $325M+ in funding (a16z, Accel, GV, etc.), looking for exceptional people to help us achieve this mission. 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 role

Join us to build the decision engine for better mental health outcomes.

As a Senior Data Scientist, you will sit in the heart of a cross-functional product team and help turn messy, real-world signals into clear decisions. You will make sure we are capturing the right data, designing experiments that tell us what is actually driving outcomes, and translating findings into recommendations that teams can act on quickly. When the insight is stable and valuable, you will help operationalize it through predictive models that improve provider and patient experiences.

If you like ambiguity, enjoy hard problems, and want your work to matter in the world, you will fit right in.

What you will do

  • Be the analytics partner inside the pod. Work closely with Product, Engineering, Design, Ops, and Clinical stakeholders to define the questions, the metrics, the guardrails, and the decision rules.
  • Run rigorous experiments. Design and analyze A/B tests and quasi-experiments with clear hypotheses, power considerations, and pre-defined success criteria.
  • Connect behavior to strategy. Use funnel, cohort, segmentation, and lifecycle analysis to understand how people and providers experience Headway, and where product changes will have the biggest impact.
  • Use causal inference when experiments are not possible. Apply approaches like diff-in-diff, matching, and regression-based designs with principled uncertainty quantification.
  • Build models when they should exist. Develop predictive models that operationalize vetted insights (feature development, validation, backtesting, calibration), with clear launch criteria and monitoring plans.
  • Create decision-ready work. Produce analysis and narratives that are crisp, honest about uncertainty, and drive action.
  • Help raise the bar. Contribute to shared standards for metrics, experimentation, and analytical quality, so teams can move faster with confidence.

What will make you successful

  • 6+ years using data to drive product or business decisions in product, growth, engineering, or operations environments.
  • Strong SQL and strong proficiency in Python or R for analysis and modeling.
  • Demonstrated depth in experimentation and causal inference under real-world constraints. Bayesian experimentation experience strongly preferred.
  • Practical modeling skill: feature engineering, model comparison, cross-validation or backtesting, calibration, and post-launch monitoring.
  • Strong product sense and opinions, including a track record of connecting analytics recommendations to measurable outcomes.
  • Clear communication: you can explain complex work to non-technical audiences without losing the truth.
  • A self-starter mindset: you prioritize well, follow through, and do not need heavy oversight.
  • Motivation for our mission: improving access and affordability in mental healthcare.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
