About this role

We are looking for a Senior Full Stack Engineer with 3-5+ years of experience to join a fast-growing AI healthcare startup and own projects that span the entire stack. You'll be building greenfield products that automate the healthcare recruiting pipeline — from sourcing to onboarding — at a company that’s already powering thousands of candidate interactions monthly and scaling to millions.

You should have experience at both an early-stage VC-backed startup and a larger tech company, bringing best practices without being rigid. This is a high-ownership role where you’ll work closely with the founding team, ship quickly, and see your work in production with real feedback loops the next day.

What will you be doing?
  • Own and deliver greenfield projects across the full stack (backend, infrastructure, and frontend) powering Take2's new product suite
  • Evolve and scale the backend architecture as the platform grows from thousands to millions of candidate interactions
  • Build and ship end-to-end features in a Type Script-first environment on serverless AWS infrastructure
  • Collaborate directly with the Director of Engineering and founding team with extremely short feedback loops and high autonomy
  • Help establish engineering standards and technical culture as a key early member of an 11-person team
Why candidates should join
  • We build AI agents that automate the entire healthcare recruiting pipeline — from screening interviews to license verifications to job offers. They already power thousands of candidate conversations monthly and are scaling to millions.
  • Backed by Human Capital (a $3B fund behind SpaceX) with a $19M Series A raised in under a month. Zero to $4M revenue in 8 months and on track for a Series B by year-end. Board advisors include ex-CHROs of Google, HP, Visa, and Disney.
  • Senior full-stack (backend-leaning) role with significant greenfield ownership. $180K-220K base + competitive equity. Hybrid in NYC (Mon-Thu) with a tight 3-round interview process.
