Headway's mission is to build a new mental health care system everyone can access. The business problem is that 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. The Ranking & Relevance team's mission is to help every patient find the right provider for their needs by building the matching system that powers this connection, from search and discovery to ranking and personalization.
Requirements
- You have 6+ years of experience in applied ML roles, with at least 1 year working on ranking, relevance, search, or recommender systems.
- You are fluent in Python and have experience with ML frameworks (TensorFlow, PyTorch, Scikit-learn, CatBoost, etc.).
- You have taken ML models from research/prototype to production at scale.
- You are comfortable designing and running A/B experiments, and you know how to choose the right offline and online metrics.
- Experience with matching systems or personalization.
- Familiarity with modern retrieval techniques (vector search, embeddings, semantic search).
- Exposure to ML infrastructure such as feature stores, model monitoring, and retraining pipelines.
Responsibilities
- Design and scale ML models that power how patients discover and connect with providers.
- Use patient signals, provider attributes, and outcomes data to improve matching accuracy.
- Establish the foundation for experimentation, model training, deployment, and monitoring across Headway.
- Guide junior ML engineers and data scientists as the team grows, setting the bar for ML practices at Headway.
- Partner with product, engineering, and data science to define success metrics, design A/B experiments, and influence product strategy.
Other
- You combine product intuition with technical depth. You care about making the patient experience meaningfully better, not just optimizing a model score.
- Headway employees work remotely across the US, with the option to work from offices in New York City, San Francisco and Seattle.
- We believe a team's strength is in its people, and we cannot achieve this mission without a team that reflects the diversity of this problem – across race, ethnicity, gender, sexuality, age, national origin, religion, family status, disability, military status, and experience.
- Headway is committed to the full inclusion of all qualified individuals. As part of this commitment, Headway will ensure that persons with disabilities are provided with reasonable accommodations.
- If reasonable accommodation is needed to participate in the job application or interview process, to perform essential job functions, and/or receive other benefits and privileges of employment, please inform the recruiter when they contact you to schedule your interview.
