About the job
ABOUT DUALENTRY
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. 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 hire outliers - people who have achieved difficult things, in their careers or beyond. You'll find leaders, colleagues who've competed at the highest levels of sport, performed on Broadway, trained with UFC champions and founded the country’s largest Python community.
WHERE YOU'LL CREATE IMPACT
- Build!
- Design backend systems and APIs (Python preferred) that run real-time, business-critical accounting logic
- Ship features end to end - architecture, CI/CD, testing, monitoring, and beyond
- Integrate third-party tools and external systems, proactively managing edge cases and risk
WHAT SETS YOU UP FOR SUCCESS
- Hardcore work ethic and high agency
- 5+ years in backend engineering (language agnostic)
- Deep experience with complex business logic products
- Strong database skills: PostgreSQL, SQL, ORMs, migrations, schema design
- Experience deploying on AWS (or similar), with solid CI/CD and production-readiness fundamentals
- Bonus: Python and a modern web framework (FastAPI, Flask, or Django)
WHY YOU’LL THRIVE HERE
- Significant equity ownership in one of the top AI companies in the world
- You’re joining early and will grow with DualEntry
- Your feedback shapes the product directly
- High-speed, high-trust environment with high expectations
MEET THE ENGINEERING TEAM
- Marcin https://www.linkedin.com/in/mkuzdowicz/ took a non-existent tax structure and built it end to end, setting the north star for how the team keeps improving it on top of it; modular and robust, always setting the bar for the rest.
- Puhiza https://www.linkedin.com/in/puhiza-doci/ grew her team from one to full capacity, while owning our integration framework end to end; scaling it to support migrations, integrations, and bank connections. The queen of I/O on our platform.
- Danylo https://www.linkedin.com/in/godspell33/ took ownership of our bank connection engine end to end and rebuilt it from scratch over a weekend.
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

- Curious: you love to learn, are highly curious about new frameworks and solutions to engineering problems
- Fast-moving: you deploy daily, iterate quickly, and never wait for permission
