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 a Senior Integrations Engineer, you’ll architect features and systems end-to-end at an incredible pace. This is an opportunity to own critical infrastructure at the early stage of a category-defining AI company. Build the first, true AI accounting product with your own hands.
This is an intense, hands-on Engineering role with full ownership. We expect you to push for excellence and raise the bar.
📍 Location: Remote with overlap to our New York City HQ (EST)
Where you'll create impact
Own end-to-end execution for backend systems and infrastructure

Own secure connectivity with banks and partners by provisioning host-to-host connections (SFTP), managing endpoint setup, and handling SSH + PGP key exchange and rotations
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

What sets you up for success
Hardcore work ethic and high agency
8+ years building backend systems, ideally in high-growth, high-ownership environments where you ship fast and own outcomes end-to-end
Deep expertise in Python and modern backend frameworks (FastAPI/Flask/Django)
Strong database fundamentals: PostgreSQL, SQL, schema design, migrations, ORMs
Experience building production-grade APIs
Hands-on with cloud infrastructure (AWS preferred) and the full delivery lifecycle: CI/CD, deployments, monitoring and incidents
Experience in payments, fintech, or financial services is strongly preferred
Familiarity with payment rails and flows (SEPA, ACH, Wires, Faster Payments, CHAPS, Bacs) and payment messaging/file formats (PAIN, CAMT) is a plus.
Able to operate in messy, evolving requirements - you design systems that scale while staying pragmatic.

Hardcore work ethic and high agency
Bonus: you’ve built bank integrations using H2H, SFTP or ISO 20022
