Govern Cloud & Infrastructure Reliability: Define production readiness criteria and operational acceptance guardrails for new or materially changed services, ensuring architecture, monitoring, logging, alerting, security controls, and recovery automation are fully validated prior to release.
Manage Service Health: Define Service-Level Indicators and Service-Level Objectives for critical services to balance deployment velocity with platform stability.
Direct Incident Response & Post-Incident Learning: Lead major incident response efforts to restore disrupted services rapidly and facilitate post-incident reviews to ensure root causes are remediated and tracked through engineering backlogs.
Day-to-Day Operations: Oversee day-to-day data centre operational management, including HPE Synergy, Hyper-V, VMware, SAN/NAS storage configuration, F5, NetScaler, file servers, database enablement (Oracle Data Guard, SQL Always On, Oracle ExaCC), data backup, networking integration (Cisco ACI and Firepower, Palo Alto Firewalls) and physical infrastructure tuning.
Proactively Manage Infrastructure Risk: Direct reliability risk assessments, capacity forecasting, and controlled resilience testing including but not limited to multi-region, availability-zone, network, and identity failure scenarios to eliminate single points of failure.
Steward Budgets: Support the governance and allocation of an annual capital budget, managing operational and capital budgets to meet product roadmap objectives within financial constraints.
Govern Vendor Relationships: Direct vendor deliverables, evaluate technology proposals, participate in contract negotiations, and establish Service Level Agreements (SLAs) and Operational Level Agreements (OLAs) with strategic partners.
Build a Culture of Innovation & Excellence: Build high-performance team capabilities in automated operations, infrastructure as code, and SRE disciplines.
