About the Role:  
We’re looking for a Senior Platform Engineer to strengthen our cloud infrastructure and developer platform capabilities. You’ll own the design, build, and operation of scalable, observable, and reliable platforms that power our applications. This is a hands-on senior role with significant ownership over Azure-based cloud infrastructure, Kubernetes orchestration, infrastructure-as-code, and full-stack observability.
 
What You’ll Do:  
  • Design, provision, and maintain cloud infrastructure primarily on Microsoft Azure (AKS, ACR, networking, storage, policies, etc.).
  • Build and operate production-grade Kubernetes clusters, including day-2 operations, scaling, security, and cost optimization.
  • Develop and evolve Infrastructure as Code (IaC) pipelines using Terraform (modules, state management, multi-environment strategies).
  • Implement and continuously improve ''observability'' across the platform using Prometheus (metrics, alerting, recording rules) and Grafana (dashboards, alerting, Loki integration where applicable).
  • Manage and harden Linux environments (Ubuntu/RHEL) – OS tuning, security hardening, logging, and troubleshooting at scale.
  • Collaborate with development and SRE teams to deliver self-service platforms, golden paths, and internal developer experience improvements.
  • Participate in on-call rotation, incident response, and post-incident reviews to drive reliability and performance.
  • Mentor junior engineers and contribute to platform standards, best practices, and documentation.
 
What You Need to Succeed:    
  • 5+ years of hands-on experience in platform, cloud, or infrastructure engineering roles.
  • Deep expertise in Azure cloud services and architecture.
  • Strong production experience with Kubernetes (deployment, operators, Helm, networking, RBAC, autoscaling).
  • Proficiency with Terraform (writing modules, remote state, testing, and large-scale usage).
  • Solid Linux administration and troubleshooting skills (kernel tuning, systemd, networking, security).
  • Hands-on experience building observability stacks with Prometheus and Grafana (or equivalent).
  • Strong scripting skills (Bash/Python) and GitOps mindset.
  • Excellent problem-solving, communication, and collaboration skills.
 
Additional Skills That Could Set You Apart: 
  • Exposure to **AWS** (any services – EC2, EKS, IAM, etc.).
  • Experience with additional observability tools (Loki, Tempo, OpenTelemetry, ELK).
  • Familiarity with GitOps (ArgoCD, Flux), service mesh (Istio/Linkerd), or policy-as-code (OPA/Gatekeeper).
  • Prior mentoring or technical leadership experience.

What We Offer

  • Opportunity to own critical platform components end-to-end
  • Modern toolset and high-impact work (Azure + K8s + observability focus)
  • Collaborative, high-performing team environment

Sitecore is proud to be an equal opportunity workplace. We are committed to equal employment opportunity without unlawful regard to race, colour, ancestry, religion, gender, national origin, sexual orientation, age, citizenship, marital status, disability, veteran status or any other local legally protected characteristic.
