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 Manager, Site Reliability Engineering to help us lead the Dublin team and evolve Site Reliability Engineering from a traditional operations model into a true Platform as a Service (PaaS) organization.

As the Senior Manager, Site Reliability Engineering for our Dublin/EMEA team, you will be the organizational and operational leader on the ground - setting strategic direction for our regional engineering hub, driving operational rigor and team execution, and partnering with engineering leaders and Principal/Staff engineers on our US and India teams to keep our global platform strategy coherent. You'll report to the Director of Infrastructure Engineering, and lead a growing team that includes Staff, Senior, and mid-level SREs.

What you'll be doing

• Leading the Dublin/EMEA Site Reliability Engineering team responsible for the architecture, availability, and evolution of our Kubernetes platform in close coordination with counterparts in the US and India

• Driving the strategic roadmap and organizational delivery of self-service platform capabilities, golden paths, and self-healing patterns that empower internal teams to ship and operate autonomously

• Directing team execution and operational readiness to host AI-driven internal workflows reliably at scale — model serving, GPU scheduling, and orchestration infrastructure

• Serving as an operational escalation point for the hardest, highest-ambiguity reliability problems, cross-regional incidents, and platform scaling challenges

• Overseeing EMEA participation in a follow-the-sun on-call rotation shared with SRE teams in the US and India, driving blameless postmortem culture and systemic remediation

• Establishing and enforcing organizational standards for SLIs/SLOs, error budgets, operational readiness reviews, and on-call health across engineering groups

• Championing modern SDLC and GitOps practices for infrastructure-as-code, ensuring robust CI/CD maturity, compliance, and safe release automation

• Hiring, retaining, and developing diverse engineering talent across all levels, mentoring technical leaders, and providing transparent career progression paths

• Partnering with product engineering, security, and enterprise architecture leaders to align infrastructure initiatives with broader reliability, compliance, and business roadmaps

• Representing the Dublin/EMEA region in global platform leadership forums, driving shared engineering culture and operational consistency across distributed teams

What you'll bring to the role

• 8+ years of total experience in Site Reliability Engineering, Platform Engineering, or Infrastructure Engineering, with 3+ years in formal people management

• Demonstrated track record of leading teams that operate Kubernetes platforms and large-scale cloud-native environments in production

• Proven experience managing mission-critical internal infrastructure platforms running in public cloud environments, preferably AWS

• Strong background guiding teams in modern cloud-native architectures, infrastructure-as-code (Terraform), and enterprise CI/CD delivery pipelines

• Experience leading infrastructure initiatives or teams supporting AI/ML workloads, agentic pipelines, GPU scheduling, or inference orchestration

• Deep familiarity with modern observability tooling and telemetry platforms (Grafana, Splunk, APM, or equivalent) to govern platform health and SLA accountability

• Demonstrated ability to influence platform strategy, resolve cross-functional misalignment, and collaborate effectively with executive stakeholders across global regions

• Outstanding verbal and written communication skills, with proven ability to build high-trust engineering culture, drive accountability, and manage organizational change

• Computer Science degree or related technical field, or equivalent practical experience
  
  

Extra credit if you have experience in any of the following

• Leading organizational transformations from traditional operations/DevOps models into dedicated "platform as a product" and internal developer platform teams

• Operational oversight of infrastructure powering AI agent orchestration, vector databases, model routing, or GPU cluster optimization

• Multi-cloud infrastructure governance and operational models (AWS plus Azure or GCP)

• Driving organizational adoption of service mesh architectures (Istio, Linkerd) or enterprise GitOps frameworks (ArgoCD, Flux)

• Kubernetes certifications (CKA, CKS, CKAD) or equivalent advanced cloud architecture credentials

• Overseeing the operation, governance, or scaling of enterprise-grade SCM and developer tooling platforms (GitHub, GitLab, or equivalent)
