Staff Software Engineer - Insurance

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 75,000 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, Spark Capital, 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.

STAFF SOFTWARE ENGINEER (INSURANCE)

The Work

The Insurance team is the backbone of Headway's business. We deliver the two core promises of the platform: affordable therapy covered by insurance for patients, and a simple way to run a therapy practice for providers. Every appointment on Headway flows through systems our team owns — from identifying whether a patient is eligible, to estimating their cost, to matching them with a provider, to submitting a clean claim.

This is a deep and wide problem. We operate across all 50 states, 1,000+ payers, and millions of appointments every month. There's a lot of data to make sense of and signal to find in the noise. As Headway's network grows — more patients, more providers, more payers — the accuracy, reliability, and automation of these systems become the difference between a business that scales and one that doesn't.

As a staff engineer in the group, you will lead design and implementation of the systems that power Headway's insurance operations — patient identification, pricing estimates, provider matching, and claims. Build data-intensive, ML-powered platforms that serve patients and providers and learn from every visit, mentor engineers, and write high-impact code at the intersection of healthcare data and payer operations.

Some examples of what that work looks like in practice:

• Building a new ML model that lifted price estimate accuracy by 10+ percentage points, getting tens of thousands of patients a better estimate ahead of their first session

• An OCR pipeline to read patient insurance cards, automate eligibility checks, and run ML models to detect complex insurance arrangements — improving onboarding and first-claim success rates

• A claims AI agent that reviews denied claims, identifies root causes, and resubmits autonomously — recovering hundreds of thousands of dollars and proving we can build self-healing systems at scale

• A human-in-the-loop automation that transformed a 20-step manual credentialing process in Google Sheets into an average of 2 days and 1 task — with a record of 6 seconds start to finish — enabling providers to onboard faster and expand their reach to new patients

Who You Are

• A platform thinker. You build for the teams behind you, not just the immediate use case. You create abstractions that let others move faster and more safely.

• Drawn to signal in messy data. Payer rules vary by state, plan, and policy. You find the structure in the noise and build systems that reason about it reliably.

• Hands-on. You write code where le
