## 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.

## What You'll Be Doing

- At Unlimit, we are building the foundation for the next generation of software delivery—where reliability, scalability, and speed come first, and AI is applied thoughtfully to amplify outcomes. As a Senior DevOps Engineer, you will lead this effort by establishing best practices, defining standards, and building the platforms that enable our teams to deliver with confidence.
- You’ll architect company-wide CI/CD strategies, design golden pipelines, and implement GitOps-based deployments and progressive delivery methods that ensure every release is predictable and resilient. Alongside Platform and Security teams, you’ll embed governance, observability, and guardrails into everything we build—so that our systems are not only automated, but trusted.
- Where AI can add value, you will pave the way. From predictive failure detection to automated root cause analysis and intelligent code quality checks, you’ll help identify and integrate the right AI-driven capabilities into our delivery lifecycle. Your work will ensure that Unlimit’s DevOps foundation is modern, adaptable, and ready for the innovations to come.
- This is a role for someone who thrives on building from the ground up, setting the standard for how software is delivered, and ensuring that every team—from developers to data scientists—benefits from a robust, future-ready platform.
