DualEntry is hiring an Integration Engineer to own the end-to-end execution of our backend systems and infrastructure. You will be responsible for secure connectivity with banks and partners, implementing payment and data pipelines, and building customer-facing integrations to accelerate our product velocity.

What You'll Do

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.
Implement and validate end-to-end payment and data pipelines—from ISO 20022 parsing/validation (PAIN, CAMT) to real-world bank testing, reconciliation, and production readiness.
Lead integration projects across banking and enterprise systems, defining scope, designing the integration approach, and driving delivery for domestic and 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 and reliability.
Debug and resolve connectivity, payment, and statement issues by tracing through logs, monitoring tools, file payloads, and database records.
Increase reliability and scale by automating onboarding and integration playbooks, standardizing test frameworks, and building maintainable backend tooling.
Drive measurable outcomes that accelerate product velocity and stability.

What We're Looking For

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.
Able to operate in messy, evolving requirements and design systems that scale while staying pragmatic.
Clear communicator (C1+ English). You can collaborate with banks, customers, and teammates across time zones.
Hardcore work ethic and high agency.

Nice to Have

Experience in payments, fintech, or financial services.
Familiarity with payment rails and flows (SEPA, ACH, Wires, Faster Payments, CHAPS, Bacs) and payment messaging/file formats (PAIN, CAMT).
Bonus: you’ve built bank integrations using H2H, SFTP, or ISO 20022.
