Payment Solution Engineer

You'll act as both project lead and solution engineer, running each integration with a regulator or provider while doing the technical implementation yourself. As Unlimit expands into new markets, you'll own the projects that connect the company to each country's banking infrastructure, including domestic clearing systems and third-party BaaS providers. You'll be the primary technical and project contact for regulators, manage onboarding from credentials through certification to production activation, and set realistic timelines you can defend and deliver against. You'll design and build the actual connections into local clearing and payment systems, then document everything so engineering and operations can maintain it after go-live.

Responsibilities

• Own central bank and clearing integration projects end to end, from kickoff to go-live
• Act as the primary technical and project contact for regulators and their assigned counterparts
• Manage the full onboarding path including credentials, environment setup, certification test cases, and production activation
• Set and defend realistic launch timelines and keep projects on track within their delivery window
• Design and implement connections that plug Unlimit into local clearing and payment systems
• Deliver integrations with third-party BaaS providers to bring additional payment rails online
• Document integrations and hand over clean, maintainable solutions to engineering and operations

Requirements

• 5+ years in payments, banking, or integration engineering, with hands-on ownership of complex integration projects
• Direct experience integrating with central banks and/or national clearing and settlement systems
• Hands-on familiarity with payment schemes and networks such as SWIFT and SEPA
• Strong understanding of payment rails, clearing, and settlement flows
• Comfort with payment messaging standards and integration patterns such as ISO 20022, MT/MX, SOAP/REST web services, and certificate-based authentication
• Ability to run a regulated project independently, managing scope, timelines, and regulator communication without close supervision
• Solid awareness of AI-driven engineering practices and where the tooling is heading
• Hands-on experience putting AI tools to work such as LLMs, AI-assisted development environments, and automation frameworks
• Clear, structured communication skills to work with regulators and technical counterparties
