Staff Site Reliability Engineer (Collaboration Engineering)

Job Description

The Staff Reliability Engineer (SRE) for Workplace Engineering is responsible for the reliability, performance, security, and operational excellence of enterprise workplace collaboration & endpoint services used globally by employees and partners. This role applies an engineering mindset to operations—defining service level indicators/objectives (SLIs/SLOs), reducing toil through automation, improving observability, and strengthening incident response—to ensure a consistent, high-quality collaboration experience across messaging, meetings, voice, file sharing, knowledge sharing, device management platforms & Copilot / AI engineering.

• Maintain a hardened security posture through automated packaging and deployment of Windows applications, maintaining a rigorous cadence for third-party updates.
• Automate repetitive configuration tasks and self-healing remediations using PowerShell and Graph API.
• Partner with Security Operations to remediate vulnerabilities.
• Develop and enforce Configuration Profiles, Compliance Policies, and Conditional Access rules.
• Own the reliability and scaling of Azure Virtual Desktop (AVD) and Windows 365 (Cloud PC), optimizing for both performance and cost-efficiency.
• Define and operationalize SLIs/SLOs and error-budget policies for collaboration services (Teams chat/meetings/voice, SharePoint/OneDrive, Exchange) with clear customer-impact measurements.
• Own end-to-end reliability engineering: capacity planning, performance tuning, resilience reviews, dependency mapping, and proactive risk reduction for critical collaboration journeys.
• Build and evolve observability for collaboration platforms: health dashboards, telemetry standards, alert strategy (high signal/low noise), and synthetic monitoring aligned to user experience.
• Lead incident response for high-severity events: establish incident roles, drive rapid triage/mitigation, coordinate cross-team communication, and produce blameless post-incident reviews with durable corrective actions.
• Engineer automation to reduce operational toil: provisioning, policy/config drift detection, lifecycle management, reporting, and remediation using PowerShell and APIs; establish reusable runbooks and self-service patterns.
• Strengthen change and release practices: production readiness reviews, controlled rollouts, maintenance windows, validation plans, and rollback strategies to reduce customer impact.
• Partner with Security/Compliance to ensure collaboration services meet governance requirements (identity and access, DLP, retention, eDiscovery, information protection), while balancing usability and reliability.
• Provide Staff-level technical leadership: set engineering standards, mentor engineers, influence roadmap priorities, and align stakeholders on reliability tradeoffs and investment.
• Establish and lead reliability operating mechanisms (on-call standards, incident command readiness, postmortem quality, action-item governance, and quarterly reliability reviews) to improve consistency across teams.
• Coach, mentor, and sponsor engineers across levels: provide technical guidance, review designs and postmortems, and raise the bar on documentation, runbooks, and operational readiness.
• Drive cross-organization alignment on reliability priorities and investment by presenting trends, risks, and proposals to leadership; secure commitments and ensure delivery against measurable outcomes.
• Serve as an escalation point for complex, cross-domain issues spanning identity, messaging, endpoints, and network dependencies; engage vendors as needed and ensure issues are driven to resolution.

Qualifications

• 12+ years of experience in reliability engineering, systems engineering, DevOps, or large-scale collaboration/communications operations (enterprise or SaaS), including ownership of production services
• Deep expertise with collaboration platforms and ecosystems: Microsoft 365 (Teams—including voice/meetings/Rooms—SharePoint Online, OneDrive, Exchange Online) and their dependencies (identity, endpoints, networking)
• Hands-on experience defining SLIs/SLOs, building observability (metrics/logs/traces), and operating an incident management program (on-call, severity model, communications, postmortems)
• Strong automation skills with PowerShell and APIs (Microsoft Graph preferred); ability to build tooling that improves reliability and reduces toil
• Experience with cloud identity and access (Microsoft Entra ID/Azure AD, Conditional Access, MFA, RBAC/PIM) and collaboration governance (Purview, DLP, retention, eDiscovery) preferred

Desired Characteristics

• Executive-level written and verbal communication skills; able to translate reliability data into clear decisions, tradeoffs, and action plans
• Proven ability to influence across functions (Security, Network, End User Computing, Architecture, Product/Program) without formal authority
• Strong systems thinking and customer satisfaction, focuses on user journeys (chat, meetings, voice, file sharing) and measurable experience outcomes
• Demonstrated technical leadership through mentorship, sponsorship, and talent development; builds inclusive, high-performing engineering culture
• High bar for operational excellence, insists on clear ownership, durable fixes, strong postmortems, and measurable follow-through
• Comfort operating in ambiguity and driving large, multi-quarter improvements with measurable results
