About the role

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.

About the company

Onshore is a technology company that is changing the tax consulting industry. We have developed artificial intelligence software that automates many of the tasks performed by tax consultants. This gets much more exciting when you consider that tax consultants earn more than $10 Billion in fees each year. That's a market worth transforming!

What is tax consulting? Good question.
Tax consultants are tax experts that analyze one or two numbers that go on a company's tax return. For example, the R&D tax credit. The rules for the R&D tax credit are very complex and most accountants do not have the expertise to compute the credit. So a company will hire a tax expert to compute the R&D tax credit for the company. That's tax consulting.
