Senior/Staff Backend Engineer (Remote)

DualEntry is building the OS for finance. Every business needs a financial system of record, yet the world's largest fintech market ($220B+) still runs on software from the 1990s, with no new entrants in 30 years. DualEntry's AI-native ERP automates accounting from data entry to close, so finance teams move faster, spend less, and incur less risk.

In just 2 years we've raised $100M+ from Lightspeed, Khosla Ventures, Contrary, and Google Ventures, and earned the trust of customers from $5M ARR to publicly traded companies.

We're hiring the outliers that can pull off this audacious goal: people that have accomplished exceptional things in their past. Our team members have been professional athletes, played for Team Canada, trained with UFC champions, performed in Broadway productions, DJ'd Berghain, and founded Brazil's top Python community.

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

As our Senior Backend Engineer, you’ll architect features and systems end-to-end at an incredible pace.

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