Staff Site Reliability Operations

For over 25 years, NVIDIA has been at the forefront of transforming computer graphics, PC gaming, and accelerated computing, driven by a legacy of continuous innovation and exceptional talent! We are now bringing to bear the immense potential of AI to usher in the next era of computing, where our GPUs power the "brains" of computers, robots, and autonomous vehicles that can comprehend the world. This pioneering work demands vision, innovation, and the world's best talent. Join our diverse and supportive environment, where NVIDIANs are inspired to excel and make a profound global impact. We are seeking a Site Reliability Operations Technical Lead to serve as the senior technical individual contributor for reliability and support at the Toronto, Canada site. This role owns technical service delivery locally, acts as the support point of last resort before regional and global platform teams, and provides technical leadership to site support engineers. Be responsible for the hardest issues across Active Directory, Exchange, database platforms, and compute infrastructure, lead the site through major incidents, and drive out the recurring problems that consume the team’s capacity. You will also lead site-level projects, represent local requirements in global initiatives, and set the technical standard the site support team works to. The successful candidate is equally comfortable running a root cause analysis, supporting an executive before an all-hands, and briefing IT leadership on site risk. What you'll be doing: • Own day-to-day site operations — incidents, requests, critical issues, and support coverage — with accountability for queue health, SLA attainment, backlog, and service quality, plus site asset and inventory management across lifecycle, refresh, procurement, and compliance. • Serve as Tier 3 escalation owner for the site and AMER across identity (AD, hybrid Entra ID, GPO, Kerberos/LDAP, SSO, MFA), messaging (Exchange hybrid mail flow, mailbox, SMTP relay), compute (Windows, Linux, macOS, virtualization, storage, and hands-on datacenter and lab hardware), and endpoint (M365, Teams, Intune, Autopilot, imaging through migrations) driving root cause and permanent fixes rather than repeat break-fix. • Own endpoint compliance, vulnerability remediation, patch management, and hardening; audit readiness and evidence; and partnership with InfoSec on incident response and privileged access. • Drive critical issues into global platform teams and vendors with reproduction cases and diagnostic evidence through to a committed fix. • Act as technical lead for site SRO engineers setting standards, reviewing work, directing blocking issues, building diagnostic rigor through mentorship, and owning the site knowledge base and runbook library. • Serve as the primary technical contact for site IT, partnering with employees, site and executive leadership, Facilities, Security, HR, and Procurement on incidents, planned changes, onboarding and moves, and office and lab expansions. • Build automation in PowerShell, Python, or Bash for diagnostics, remediation, health checks, and reporting; analyze ticket and reliability trends to eliminate top recurring drivers; and champion AI-driven and agentic solutions that advance SRO strategy. • Represent site and AMER priorities in regional and global IT initiatives, standards, and architecture forums, and lead operational decisions in the manager's absence. What we need to see: • 8+ years in enterprise support engineering, infrastructure, or end user services, including 5+ years in a senior, lead, or escalation-tier role in a multi-site environment. • Deep hands-on solving across Active Directory and hybrid Entra ID, Exchange hybrid, Windows and Linux server, virtualization, enterprise storage
