Senior Bank & Integrations Engineer

Job descriptionAbout DualEntryFounded 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 NowSince 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. This is an intense, hands-on role with full ownership. We expect you to push for excellence and raise the bar. Where you'll create impactOwn end-to-end execution for backend systems and infrastructureOwn secure connectivity with banks and partners by provisioning host-to-host connections (SFTP), managing endpoint setup, and handling SSH + PGP key exchange and rotations.

Implement and validate end-to-end payment and data pipelines — from ISO 20022 parsing/validation (PAIN, CAMT) to real-world bank testing (penny tests), reconciliation, and production readiness. Lead integration projects across both banking and enterprise systems, defining scope, designing the integration approach, and driving delivery for domestic + international payment flows. Build and maintain customer-facing integrations between DualEntry and third-party platforms (AP/AR tools, billing, CRM, payroll, data warehouses), ensuring data accuracy, reliability, and clean sync behavior.

Debug and resolve connectivity, payment, and statement issues by tracing through logs, monitoring/observability tools, file payloads, and database records. Increase reliability and scale by reducing manual work: automate onboarding and integration playbooks, standardize test frameworks, and build maintainable backend tooling that keeps pipelines stable.
