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.

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.
