You can replace repetitive workflows with reliable automation, make provisioning and onboarding faster, and drive down error rates — freeing the whole team to focus on higher-value work.The security posture strengthens visibly. You can track and close vulnerabilities on a predictable cadence, make access reviews routine rather than fire drills, and keep SOX and compliance evidence clean, complete, and audit-ready.Incidents are handled with maturity. You can bring a fast, calm response to critical issues and drive real root-cause analysis rather than band-aids, so the same problem doesn't resurface.The roadmap is proactive, not reactive. You can anticipate where the infrastructure and business are heading and propose initiatives ahead of need, rather than only responding to what breaks.Requirements5-8 years of experience in IT Systems Administration or infrastructure roles in a corporate environmentAdvanced proficiency with Office 365 and Google WorkspaceStrong experience with automated deployment and MDM platforms (Intune, Mosyle, Kandji, JAMF, or equivalent) for Mac and WindowsSolid networking foundation: routing, switching, VLANs, firewalls, DHCP, DNSHands-on experience managing and troubleshooting firewall and network hardware (Cisco Meraki experience strongly preferred)Scripting or programming proficiency in at least one language (Python, Bash, PowerShell, Go, or similar)Experience with identity and access management: Azure AD / Microsoft Entra ID, Okta, or equivalent SSO/IdPDemonstrated ability to independently manage multi-month infrastructure or process improvement projectsExperience with video conferencing systems (Zoom, Google Meet, meeting hardware)Jira/Confluence administration experience a plusExcellent communication skills: able to write clear technical documentation and present recommendationsSome company benefits includeCompetitive salaryHealth, dental, and vision insurance, plus mental health resources401(k) match and generous PTOHybrid work environment (NYC office)Free lunch for onsite team members in NYCVolunteer OpportunitiesOpportunities for professional development in a high-growth ad tech companyGreater NY-area Residents: We currently have a hybrid remote work policy.
