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, 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. WHAT SETS YOU UP FOR SUCCESS - Hardcore work ethic and high agency - shipped and maintained at least one production app end-to-end - at least +4 years with React Native (or native iOS/Android + fast RN ramp) with Expo experience - At least +5 years with Typescript - Comfortable with Expo + EAS (Build, Submit, Update) - Owned a full store release cycle: signing/provisioning, TestFlight (iOS) & internal tracks, review back-and-forth - Solid mobile perf instincts (Hermes is a nice to have) Nice-to-have: - Shipped something with real scale (offline-first, 100k+ users) - Has written or patched a native module (Swift/Kotlin) - iOS development experience - Mobile observability - Active github 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 - Ignacio https://www.linkedin.com/in/ignaciobrasca/ 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. Pure initiative, compounding. - 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. - Viktor https://www.linkedin.com/in/imviidx/, Vale https://www.linkedin.com/in/vale-yakymenko/, and Przemek, the reporting trident, built our entire reporting ecosystem from scratch, serving reports in second-like query times. 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 - 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 COMPENSATION & BENEFITS - Equity: $40,000 - $60,000 USD - Base Salary: $120,000 - $180,000 USD - Remote-first team - the fastest team you will have ever worked with - PTO (27 days incl. public holidays) - Home Internet, Co-working space, office setup support - Unlimited AI token usage - AI skills development and enablement - Learning & development budget for courses, certifications, and language learning - Visa sponsorship and relocation support for a move to NYC (after 2 years’ tenure) “Join us to fix the boring, think the hard, and build the impossible, so we become the most robust engineering platform for accounting the world has ever seen.” Ignacio Brasca, Head of Engineering
