- Ship full-stack features across our Vite + React frontend (shadcn, Tailwind) and SST backend (Bun, Lambda, AWS).
- Build AI-powered data pipelines that ingest, extract, and transform client data at scale.
- Own products from spec to production — design, build, deploy, iterate.
- Work directly with founders, tax experts, and customers.
You should have
- 2+ years building production software, ideally full-stack.
- Strong TypeScript and React. Comfort in a serverless AWS environment is a plus.
- A bias toward shipping and an eye for craft.
Compensation
- $155K–$170K base
- Up to $15K/year in equity
- Full benefits
NYC, in-office.
