• Proven experience defining and operating SLIs/SLOs and error budgets.
• Hands-on experience securing Azure cloud environments—identity/access, network security, posture management (e.g., Microsoft Defender for Cloud, Azure Policy), and vulnerability management.
• Experience scaling Microsoft Fabric and Microsoft Purview.
• Experience owning incident management, on-call, and blameless post-incident reviews (e.g., Better Stack, PagerDuty, or comparable).
• Strong scripting/automation ability (e.g., PowerShell, Python, Bash) and CI/CD experience (Azure DevOps preferred).
• Experience supporting business continuity and disaster recovery with defined RTO/RPO.
• Experience building internal developer platforms, golden paths, and self-service infrastructure.
• Cloud cost optimization / FinOps experience.
• Exposure to AI-assisted operations (AIOps) and modern reliability automation.
• Microsoft Azure certifications (e.g., Azure Solutions Architect Expert, Azure DevOps Engineer Expert, Azure Security Engineer Associate) preferred.
• Experience in insurance, travel, fintech, or SaaS (regulated environments) preferred.
• Prior leadership or mentoring of distributed/offshore teams desired. Formal people-leadership experience a plus

RESPONSIBILITES

Infrastructure Strategy

• Own and evolve TII’s Azure infrastructure and reliability roadmap, aligned to the Azure Well-Architected Framework.
• With the AVP, Infrastructure to co-create the future-state vision and roadmap for Cloud, Observability, ITSM, and related domains.
• Define standards for compute, network, and platform services that scale with business growth and new channels.
• Drive cloud cost optimization (FinOps)—balancing performance, resilience, and spend.
• Partner with engineering architecture to ensure infrastructure enables design-time resilience and delivery velocity.

Site Reliability Engineering

• Own run-time reliability across availability, performance, scalability, and capacity for TII’s platform.
• Mature and expand the SLO practice—defining SLIs, refining the 99.9% (and higher, where warranted) SLOs, and operating error budgets to balance reliability and delivery speed.
• Lead capacity planning and performance engineering to support the platform’s growth.
• Drive operational readiness reviews for new services and major releases.

Observability

• Own and mature the observability platform across the three pillars—metrics, logs, and traces—enhancing Grafana/Prometheus and Azure Application Insights.
• Implement distributed tracing across the GraphQL/REST services to accelerate diagnosis and reduce time-to-detect and time-to-resolve.
• Establish meaningful alerting and telemetry that reduce noise and surface real signals.
• Build reliability dashboards that give teams and leadership clear visibility into service health.

Platform Engineering

• Own the internal developer platform and self-service infrastructure capabilities that enable engineering teams to provision and operate safely.
• Define golden paths / paved-road templates that make the reliable, secure, and compliant way the easy way.
• Establish and champion Infrastructure as Code standards using Bicep and Terraform.
• Improve developer experience and engineering enablement through automation and reusable platform services.

Operational Excellence & Automation

• Drive automation across provisioning, configuration, deployment, and remediation to eliminate toil.
• Establish operational runbooks, self-healing patterns, and proactive reliability practices.
• Continuously improve deployment safety and rollback capability in partnership with CI/CD owners.

Cloud Security & Compliance

• Own the engineering and operational security of the Azure cloud platform—including identity and access management, network security, configuration hardening, and secrets/key management.
• Manage and improve the cloud security posture (e.g., Microsoft Defender for Cloud, Azure Policy), including continuous vulnerability management and remediation.
• Implement security monitoring and alerting as part of the observability platform to detect and respond to threats.
• Embed DevSecOps and secure-by-design practices into platform and IaC workflows, enforcing guardrails and policy-as-code within golden paths and self-service tooling.
• Partner with the Security function on policy, governance, and compliance in a regulated insurance (PII) environment.

Incident & Problem Management

• Own the major-incident process and incident command, matured on the on-call platform (Better Stack).
• Lead blameless post-incident reviews and drive systemic problem management to prevent recurrence.
• Improve on-call health, escalation paths, and mean-time-to-detect / mean-time-to-resolve.
• Maintain and enhance the mature Business Continuity and Disaster Recovery capabilities, including RTO/RPO targets and periodic testing.

Leadership

• Will co-lead a small team of infrastructure, cloud, & system engineers.
• Uplift the reliability and platform capability across engineering—raising standards and building a reliability culture.
• Mentor engineers, demonstrating the leadership behaviors that support growth into a formal infrastructure leadership role.
• Establish standards, documentation, and ways of working that scale across teams.
• Other duties as assigned
