Job Title: Principal Engineer, SRE & Service Operations

About this role

• Design, implement, and maintain highly available, scalable, and resilient cloud infrastructure across AWS, GCP, and OCI as the primary platforms.
• Provide technical leadership and architectural expertise in Site Reliability Engineering (SRE) practices - covering observability, incident management, chaos engineering, and reliability frameworks.
• Lead infrastructure automation initiatives using Terraform, Ansible, and Python to drive zero-touch provisioning and configuration management across multi-cloud
• Define and enforce SLOs, SLIs, and Error Budgets across critical services, ensuring reliability targets are met without compromising velocity.
• Architect and operate Kubernetes-based workloads (EKS, GKE, OKE) with a focus on scalability, cost optimisation, and platform resilience.
• Own observability and monitoring strategy using tools such as Grafana, Prometheus, CloudWatch, and Cloud Monitoring to ensure proactive detection and resolution.
• Collaborate with development and platform teams to embed reliability, security, and performance standards into the software delivery lifecycle.
• Lead incident response, post-mortem culture, and continuous improvement initiatives to reduce MTTR and eliminate repeat failures.
• Ensure infrastructure design and operations align with regulatory, compliance, and data sovereignty requirements across cloud regions.
