Description
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.
