Software Engineer II — Onshore

Onshore builds AI-native tax software. We automate the work that used to take CPAs weeks — R&D credits, 179D, cost seg, and more — using agents that do the analysis and humans who review it.

We're hiring a Software Engineer II to build product end-to-end across our stack.

What you'll do

• 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.
