Senior Bank & Integrations Engineer

Founded in 2024, Dual Entry is one of the world’s fastest-growing AI startups.

At Dual Entry, the future of finance is being written today. ERP is one of the largest fintech markets in the world ($,000+). Yet, tens of thousands of companies are still using on‑premise systems, and the industry has not seen new entrants in more than 30 years.

Our AI‑native ERP lets accounting teams achieve more in less time. $5M‑ARR businesses to NYSE‑listed companies trust Dual Entry to automate away manual data entry work with AI. We’re finally making the one‑person finance team a reality and putting the pain of legacy ERPs from the 1990’s in the past.

We operate with urgency and ownership. We move fast.

Why this role matters now
Since starting 18 months ago, we’ve raised $+ from world‑class investors such as Lightspeed Venture Partners, Khosla Ventures, Contrary Ventures and Google Ventures, as well as more than 20 angel investors who’ve built, scaled, and exited some of the most impactful companies of the last decade.

We got there by moving incredibly fast and hiring an exceptionally sharp, hard‑working and deeply committed team from leading tech and accounting companies – Ramp, Meta, Microsoft, Lyft, PwC, Deloitte, J.P. Morgan, Bloomberg, Sage, Xero and Intuit. And some of us don't have a fancy logo on our resume and are here for a shot to prove ourselves.

We’re a small team, growing fast with huge momentum –  join early.

As a  Senior Bank & Integrations Engineer , you’ll architect features and systems end‑to‑end at an incredible pace. This is an opportunity to own critical infrastructure at the early stage of a category‑defining AI company. Build the first, true AI accounting product with your own hands.

This is an intense, hands‑on  Engineering  role with full ownership. We expect you to push for excellence and raise the bar.
