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.

We are looking for a Senior Cloud Platform Engineer to design, build, and scale the platform that powers our entire engineering organization. You will design and implement scalable, multi-region cloud infrastructure in AWS, create self-service capabilities, implement observability systems, and set the guardrails for reliability and security—ensuring our platform is resilient, compliant, and ready to support AI-driven innovation across Unlimit.

What You'll Be Doing

• At Unlimit, our platform is the foundation on which everything else is built—applications, services, and even AI-enabled solutions depend on it. As a Senior Cloud Platform Engineer, your first mission will be to design and implement multi-region AWS infrastructure that can scale reliably and securely to meet the demands of our fast-growing business.
• From there, you will manage Kubernetes clusters at scale, define golden paths that enable developers to build and deploy quickly, and implement Infrastructure-as-Code and GitOps workflows that make provisioning and delivery seamless. You’ll build self-service portals that let teams spin up environments within minutes—while ensuring that guardrails, governance, and security standards are always in place.
• This role goes beyond automation. You’ll embed observability, resiliency, and zero-trust security into the fabric of our platform. Where AI can add value, you’ll pave the way—introducing AIOps bots, automated remediation, and ChatOps integrations that reduce toil and improve responsiveness. Your work will ensure the platform is not only reliable today, but also ready to support the AI-powered services of tomorrow.
• As a Cloud Platform Engineer, you will set the standards for how infrastructure is built, secured, and operated—directly influencing the speed, reliability, and scalability of everything Unlimit delivers.
