About DualEntry
Founded in 2024, DualEntry is one of the world’s fastest-growing AI startups.
At DualEntry, the future of finance is being written today. ERP is one of the largest fintech markets in the world ($220,000,000,000+). 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 DualEntry 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 $100,000,0000+ 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 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.
📍 Location: New York City HQ, 7 World Trade Center
Where you'll create impact
- Design and build core backend systems (Python preferred)
- Build APIs, services and infrastructure that handle real-time, business-critical and complex accounting logic
- Launch production-ready features from scratch, including CI/CD pipelines and deployment
- Work with product to turn complex finance workflows into performant, secure systems
- Manage complexity in a business-logic-heavy product, including data migrations and scale challenges
- Integrate third-party tools and external systems - proactively managing edge cases and risk
- Own your work from architecture to testing, monitoring, and post-release care

What sets you up for success
- Hardcore work ethic and high agency
- 3+ years of experience in backend engineering (language agnostic)

- Solid understanding of software lifecycle, CI/CD, and production-readiness
- Ability to manage complex systems with evolving requirements
- Python and a modern web framework (FastAPI, Flask, or Django) is a plus
How you operate
- Pragmatic: you like to move forward and make decisions based in reality (not theory). We don't debate if Cassandra has the most theoretical scalability -- we use Postgres until it breaks
- Hard working: 'You can work long, hard, or smart, but [here] you can't choose two out of three" - Jeff Bezos. We wrote this job post during the weekend
- Curious: you love to learn, are highly curious about new frameworks and solutions to engineering problems
