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!

• Embed on named customer projects and own them end to end: discovery, design, build, deploy and verify
• Build migration and integration pipelines on Temporal that are idempotent, resumable, and auditable
• Model and load customer accounting data into Postgres correctly, including reconciling against their existing system
• Build internal tooling so recurring one-offs stop being one-offs
• Feed patterns back into the core product, and productize or hand off anything that becomes permanent
• Compress the path from “customer requested” to “shipped"

What Sets You Up for Success

• Hardcore work ethic and high agency
• 5+ years shipping production full stack software, end to end and unsupervised
• Django and DRF, plus Postgres beyond ORM defaults. You read query plans and you have run migrations against live data with customers on it
• Next.js and React with TypeScript
• Durable workflow experience. Celery preferred
• Direct customer exposure on past experiences. You have sat with a customer, scoped the problem with them, and shipped against it
• Experience with third party APIs, webhooks, rate limits, reconciling two systems that disagree

Nice to Have

• Accounting, ERP, or fintech domain knowledge: double-entry, chart of accounts, close, AP/AR, revenue recognition
• Prior forward deployed, applied, or special projects experience
• Judgment about when to ship a script versus build a system
• 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 Team

Ignacio shaped the baseline of our integration framework from scratch in a single weekend, then spent most weekends - while coordinating the team - shipping what was never on the roadmap: webhooks, a search engine for millions of transactions, and Puma itself

Marcin 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 grew her team from one to full capacity, while owning our integration framework. The queen of I/O on our platform

Danylo took ownership of our bank connection engine end to end and rebuilt it from scratch over a weekend
