AI native start-up not just focused on building a tool for bookkeepers. They’re replacing the job entirely. Part of Founding engineering team, with $10m seed, led by Khosla Ventures.

Small business bookkeeping, manual, expensive, error-prone hasn’t fundamentally changed in decades. This team is synthetically recreating the entire profession with autonomous AI, and they need a Staff or Principal engineer to help architect it from the ground up.

No legacy systems. No ML research theatre. Just real agents doing real financial work for real customers.

– Build AI agents that autonomously run end-to-end bookkeeping workflows for SMBs

– Own integrations with Ramp, Brex, Gusto — scoping through production, no handoffs

– Architect an accounting ledger from scratch — the core financial data infrastructure

– Ship daily in TypeScript/Next.js, full stack (60% frontend, 40% backend)

– Talk directly to test customers and partners you drive the product, not a spec doc

You’ll fit if you’ve got:

→ 5+ years hands-on software engineering

→ Deep TypeScript/Next.js fluency across the full stack

→ Real experience building with LLMs/AI agents in production

→ Comfortable owning ambiguous problems with minimal direction

→ Ready for high-intensity, high-ownership founding-team pace

3 Stage interview process, with an optional paid work trial.

If “replacing an entire profession with autonomous AI” excites you, this is the one.
