As the global leader in high-speed connectivity, Ciena is committed to a people-first approach. Our teams enjoy a culture focused on prioritizing a flexible work environment that empowers individual growth, well-being, and belonging. We’re a technology company that leads with our humanity—driving our business priorities alongside meaningful social, community, and societal impact.
As a senior member of Ciena’s collaboration technology team, this role strengthens the digital workplace by ensuring reliable, scalable, and secure Microsoft 365 services. It drives operational excellence across enterprise collaboration tools and plays a key role in enabling seamless communication, global teamwork, and efficient productivity across the organization.
This role sits at the center of how employees collaborate every day. You’ll shape how Collaboration services are governed, secured, and evolved at enterprise scale, with great influence over platform direction
How you will make an impact:
Serve as a technical owner and subject‑matter expert for collaboration platforms, influencing standards, roadmaps, and adoption strategies rather than administration only
Act as a technical escalation point and mentor for other engineers and support teams, helping raise the overall bar for collaboration services
Lead administration and optimization of Microsoft Teams, including Teams Rooms, Teams Phone, and enterprise meeting experiences
Oversee architecture, governance, and lifecycle standards for SharePoint Online environments
Administer core Microsoft 365 services such as Exchange Online, OneDrive, Azure Active Directory (Azure AD)—now Entra ID—and Security & Compliance features
Drive proactive monitoring, telemetry, and alerting through tools such as Datadog to ensure platform stability
Direct Tier 3 incident response, root‑cause analysis, and service restoration for high‑impact collaboration issues
Deliver cross‑functional projects including feature rollouts, migrations, voice deployments, and governance initiatives
Strengthen service management practices by advancing documentation, knowledge resources, and continuous improvement efforts
The must haves:
10+ years overall IT experience, including 6-8+ years of deep, hands‑on Microsoft 365 ownership in a large enterprise environment
Deep hands‑on expertise with Microsoft Teams, including Teams Rooms, Teams Phone, and large‑scale meeting solutions
Strong knowledge of SharePoint Online architecture, governance, and site management
Experience using Datadog or similar tools to monitor collaboration services
Demonstrated delivery of technical projects from design through implementation
Solid understanding of Entra ID, security controls, and compliance capabilities (including DLP, retention, and eDiscovery)
Experience working within an ITIL‑based service environment such as ServiceNow
Nice to haves:
Exposure to Microsoft Copilot, AI feature readiness, and governance considerations within Microsoft 365 environments
PowerShell automation experience for Microsoft 365 administration
Background in large‑scale Microsoft Teams or SharePoint migrations
Microsoft certifications such as MS‑102, MS‑700, PL‑100, or PL‑300
Experience supporting global or highly distributed enterprise environments
Familiarity with integrating collaboration platforms with network, AV, or voice systems
Exposure to governance frameworks that extend across cloud collaboration tools
Ability to influence platform strategy through data‑driven insights
