Onshore builds AI-native tax software for the people who build America. Farmers, manufacturers, and founders do the R&D that moves this country forward — and most never get the credit they've earned. We're fixing that: our agents do the analysis that used to take CPAs weeks, our experts review it, and our customers get their money back. We started with R&D tax credits and are expanding into agricultural incentives, corporate tax returns, and other tax incentives.
We're hiring a Software Engineer I to ship product across the platform and grow fast alongside a small, senior team.
What you'll do
Ship full-stack features across our Vite + React frontend (shadcn, Tailwind) and TypeScript backend (Bun, Hono, SST v3 on AWS).
Contribute across our four product surfaces: the core R&D credit platform, agriculture incentives, corporate tax and compliance, and the agentic infrastructure that powers all of them.
Work with AI-powered data pipelines — document extraction, RAG over tax authority, and agent workflows built on frontier models.
Learn from senior engineers through tight code review and pairing, and take on increasing ownership as you ramp.
Our stack
TypeScript end-to-end — Bun + Hono services, Vite + React (shadcn, Tailwind) on the front.
SST v3 on AWS: Lambda, ECS/Fargate, SQS, Step Functions.
Aurora Postgres with Drizzle ORM, Pinecone for RAG, Clerk for auth.
Frontier LLMs powering extraction, analysis, and agent workflows.
You should have
0–2 years of professional experience (internships and serious side projects count).
Strong fundamentals in TypeScript or a similar language, and hunger to learn the rest.
A bias toward shipping and pride in your craft.
