Sr. Cloud Platform Engineer

Team: Architecture

Location: Belgrade

Commitment: Full-Time

Workplace Type: onsite

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.
