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 II to own product end-to-end across our stack.
What you'll do
Own full-stack features from spec to production across our Vite + React frontend (shadcn, Tailwind) and TypeScript backend (Bun, Hono, SST v3 on AWS — Lambda, ECS/Fargate, SQS, Aurora Postgres with Drizzle).
Build in one of four areas: the core R&D credit platform, agriculture incentives, corporate tax and compliance (our 1120-S product), or agentic infrastructure.
Build AI-powered pipelines that ingest, extract, and verify client data at scale — agents, RAG (Pinecone), and durable execution workflows.
Work directly with founders, tax experts, and customers; mentor SWE Is as the team grows.
Our stack
TypeScript end-to-end — Bun + Hono services, Vite + React (shadcn, Tailwind) on the front.
