Job description

• Okta authenticates, authorizes, and provisions millions of users a day
• Internally, TDI Infrastructure Engineering runs the platforms that our own engineering and business teams build on — hosted on AWS, increasingly Kubernetes-native, and expanding fast to support AI-driven internal workflows
• We’re looking for a Senior SRE to help us evolve Site Reliability Engineering from a traditional operations model into a true Platform as a Service (PaaS) organization
• As a Senior Site Reliability Engineer on our Dublin/EMEA team, you will build and operate the Kubernetes-based platform that hosts internal workflows across the business, with a growing focus on hosting AI-driven workflows reliably in production
• You’ll report to the Senior Manager, Site Reliability Engineering, and work closely with a Staff SRE and the rest of the Dublin team, as well as SRE peers in the US and India
• Building, operating, and improving our Kubernetes platform — cluster management, networking, security posture, and day-2 operations
• Developing self-service capabilities, golden paths, and automation that let internal teams onboard and operate workflows with less platform expertise required
• Supporting the platform’s readiness to host AI-driven internal workflows reliably at scale
• Troubleshooting and resolving production issues, including participating in a follow-the-sun on- call rotation shared with SRE peers in the US and India, and driving postmortems for incidents you own
• Contributing to and upholding reliability practices — SLIs/SLOs, error budgets, and operational runbooks
• Improving CI/CD pipelines and infrastructure-as-code practices, including change and release management
• Building and maintaining observability and monitoring coverage for the systems you own
• Mentoring junior engineers and contributing to design and code reviews
• Collaborating with the Staff SRE and Dublin team to align local implementation with the broader global platform strategy
