Senior DevOps Engineer at five9

This role is designed for an experienced infrastructure specialist or Site Reliability Engineer with at least 5 years of experience, specifically those who have moved beyond the public cloud to manage Kubernetes on-premises and on bare-metal hardware. If you are comfortable digging into Linux internals, networking, and cluster tuning, you will thrive in this platform-focused environment. While the base salary isn't listed, the package is robust for the Porto market, featuring a 10% flex benefit, a bonus scheme, and company shares. As a hybrid role, it offers a balance of office collaboration and remote flexibility, with a generous 25 days of annual leave plus public holidays. **You might be a good fit if you...** * Have deep production experience running Kubernetes on bare-metal or OpenStack rather than just managed cloud services. * Are a GitOps enthusiast who defaults to using Terraform, Helm, and Argo CD for automation. * Enjoy the "lower-level" side of DevOps, including performance tuning for CPU/memory and strengthening cluster security. * Hold a CKA or CKS certification and have worked in highly regulated environments like PCI or SOC2.
