About the role:

We are looking for a highly skilled Level 3 SaaS Systems Administrator with deep expertise in collaboration and productivity platforms. This role is all about technical depth — solving the toughest problems, digging into logs, writing automation, and owning the stability of Slack, GSuite, Zoom, Jira, and Office 365. You'll be the go-to expert for escalations, a troubleshooter and partner who thrives on solving what others can't, and someone who can engineer smarter ways to keep systems running seamlessly to drive employee productivity.

What You'll do:

• Serve as the final escalation point for complex incidents/requests across Slack, Google Workspace, Zoom API Management, ProofPoint, Jira & Confluence, and Office 365.
• Perform deep troubleshooting at the application, integration, and infrastructure layers — including API calls, logs, and network dependencies.
• Configure, optimize, and maintain these platforms for performance, security, and scalability.
• Write and maintain automation scripts (PowerShell, Python, or similar) for repetitive tasks, reporting, and integrations.
• Diagnose and resolve authentication/SSO/MFA issues (Mainly Okta, some Microsoft AD).
• Analyze system and application logs to pinpoint root causes and prevent recurrence.
• Manage and troubleshoot integrations between collaboration tools (e.g., Slack bots, Jira workflows, Zoom add-ons, Office 365 connectors).
• Drive and/or otherwise assist with SaaS application deployments, upgrades, and migrations.
• Partner with vendors to resolve critical platform issues and escalate when necessary.
• Document troubleshooting processes, scripts, and technical solutions for knowledge sharing.

What you bring:

• 6+ years of hands-on IT support, systems engineering, or SaaS administration.
• Expert-level experience with Slack admin console, Google Workspace, Zoom API Management, Jira & Confluence Administration, ProofPoint, and Office365 tenant management.
• Strong background in identity and access management, including SSO integrations, MFA, and directory services (Okta).
• Practical knowledge of networking fundamentals (DNS, VPN, TLS/SSL, proxies, firewalls) as they relate to SaaS applications.
• Experience with VMware ESXI or similar tools.
• Proficiency in scripting/automation (PowerShell, Python, or similar).
• Ability to debug APIs and integrations between enterprise SaaS platforms.
• Comfortable working in log analysis tools, monitoring dashboards, and vendor escalation portals.
• Strong analytical and troubleshooting mindset — proven track record of resolving "unsolvable" issues.
• Very strong 'can-do' attitude with a strong desire to partner with the Engineering and Security teams that we work with every day.

Nice to have:

• Experience in a SaaS, startup, or high-growth tech environment.
• Familiarity with device management platforms (Intune, Jamf).
• Knowledge of security/compliance frameworks (SOC2, ISO27001, HIPAA).
• Experience with automation and/or AI platforms.
