About Unlimit
Unlimit is a global fintech ecosystem built to eliminate financial borders holding businesses back. The company provides the extensive infrastructure needed to scale globally, integrating payment processing, multi-currency business accounts, BaaS and crypto gateways into a single, intelligent platform.
Across 17 offices globally, Unlimit bridges hyper-local expertise with a high-capacity financial network, giving companies the agility to expand across regions with operational confidence and speed. Driving the evolution of payments, Unlimit is transforming its infrastructure from human-operated fintech into AI-native financial infrastructure — where APIs are consumed by machines, integrations are negotiated by agents, and systems evolve continuously through intelligent automation. Our next users are not only humans. They are AI agents acting on behalf of humans and businesses.
Unlimit serves more than the needs of businesses today; we are building the nervous system for a borderless global economy.
About the Role
Unlimit is undergoing a deep technology transformation. As a global fintech with a robust suite of products — including card acquiring, banking-as-a-service, payment gateways, crypto solutions, and wallets — we’re rebuilding our core backend platforms to be AI-native , modular , and cloud-agnostic .
We’re seeking a forward-thinking and hands-on Solution Architect to lead this transformation from within. This is a strategic yet execution-driven role: you’ll help define and implement next-generation architecture that’s scalable, resilient, and designed with real-time AI capabilities.
You’ll work at the intersection of architecture, infrastructure, and delivery, collaborating closely with Product, DevOps, Engineering, and Data teams. Your work will directly shape systems that serve thousands of merchants globally — with near-zero downtime, built-in observability, and seamless integration of AI agents into critical paths. This is a rare opportunity to join Unlimit at a pivotal point and define the future of financial infrastructure.
