Senior Software Engineer

What You'll Do This is a true ground-floor role: you'll be writing code that powers billions of dollars in cashflow for hospitals and physician groups, while shaping the product and culture of the company from day one. Expect your friends to ask why you're working so hard — and then ask if they can join. (intentional, non-AI em dash btw) What the First 90 Days Look Like First 30 days: Ship the LLM-frist, automated dispute-tracking pipeline that our top 3 law firm partners depend on. You'll own it end-to-end: data ingestion, status updates, and the provider-facing dashboard. First 60 days : Take over the eligibility engine and benchmark infrastructure backed by 1.8M verified IDR pricing records. Redesign the data pipeline to handle deployment across 200 provider groups. First 90 days : Lead architecture decisions across the platform. Begin building and managing the engineering team (on/offshore). You're operating as de facto CTO.
