Job summary

Okta is seeking a Senior Site Reliability Engineer for the Dublin/EMEA team to build and operate the Kubernetes-based platform that hosts internal workflows and supports AI-driven production workloads.

You will collaborate with global SRE peers, report to the Senior Manager, Site Reliability Engineering, and mentor junior engineers while driving reliability, CI/CD improvements, and observability across our cloud-based infrastructure.

Qualifications

• 5+ years of experience in Site Reliability Engineering, Platform Engineering, or Infrastructure Engineering.
• Strong hands-on experience with Kubernetes in production — deployment, networking, security, and troubleshooting.
• Experience operating large-scale internal infrastructure platforms in a public cloud, preferably AWS.
• Solid experience with infrastructure-as-code (Terraform) and CI/CD pipelines.
• Exposure to or interest in building infrastructure that hosts AI/ML or agentic workflows.
• Experience with observability platforms and monitoring tools (Grafana, Splunk, APM, or equivalent).
• Comfortable working in a fast-moving, evolving environment with ambiguity around process and tooling.
• Effective verbal and written communication skills, with the ability to collaborate across time zones.

Responsibilities

• Build and operate the Kubernetes-based platform — cluster management, networking, security posture, and day-2 operations.
• Develop self-service capabilities, golden paths, and automation for internal teams.
• Support readiness to host AI-driven internal workflows reliably at scale.
• Troubleshoot production issues; participate in follow-the-sun on-call rotation and drive postmortems.
• Contribute to reliability practices — SLIs/SLOs, error budgets, and runbooks.
• Improve CI/CD pipelines and infrastructure-as-code practices, including change and release management.
• Build and maintain observability and monitoring coverage for owned systems.
• Mentor junior engineers and participate in design and code reviews.
• Align local implementation with the broader global platform strategy.

Identity is the key to unlocking the potential of AI. Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era. This work requires a relentless drive to solve complex challenges with real-world stakes. We are looking for builders and owners who operate with speed and urgency and execute with excellence.

This is an opportunity to do career-defining work. We're all in on this mission. If you are too, let's talk.

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.
