We have built a flexible work environment where new ideas are encouraged and everyone is a stakeholder.

What you'll be responsible for

The Senior IT Systems Administrator is a key, hands-on role based onsite at Circle's New York City office, Monday through Friday, full-time. You will maintain and improve our Mac environment, office network (Cisco Meraki), and audio-visual systems, and provide white-glove support to executives and employees in the office, remote support for our remote-first workforce, and live support for meetings and onsite events. The pace is fast, with frequent walk-ups and interruptions, and you will work as part of a 24x7 global IT team.

We're looking for an energetic, pragmatic people-person who is collaborative and hands-on, comfortable working at the intersection of AI, infrastructure, and customer support, and eager to help modernize how IT runs.

What you'll work on

• Provide white-glove support for software, hardware, and network issues to on-site executives, employees, traveling teams, and visiting customers. Diagnose problems, guide the fix, and keep the office running.
• Provide remote support to employees working outside the office in a remote-first company.
• Log, assign, track, and verify incidents and service requests through resolution in the ticketing system, including computers, printers, and requests from internal application teams.
• Deploy, configure, and maintain MacBooks and peripherals, and manage them through Iru (MDM).
• Maintain the office network, including Cisco Meraki equipment, firewalls, managed switches, VLANs, and routers.
• Support audio-visual systems across the office: conference rooms (Zoom, Google Meet), presentation boards, and displays.
• Operate and troubleshoot live audio, camera, and display equipment during large presentations and events, including occasional evening events.
• Manage and troubleshoot office security systems, including facial recognition, security cameras, and card readers.
• Support IT business continuity and disaster recovery for the office: planning, documentation, testing, and recovery readiness. Participate in semiannual disaster recovery tests; verify replication, redundancy, backups, and archiving; identify gaps; and restore servers, networks, and applications.
• Partner with the cybersecurity team to enforce security policies, manage network access, monitor for suspicious activity and vulnerabilities, and help respond to and remediate incidents.
• Use AI tools to speed up troubleshooting, debugging, and routine work.
• Keep runbooks current, including escalation paths.

What you'll bring to Circle

• Ability to work onsite at the New York City office, Monday through Friday, full-time, with occasional after-hours support for events.
• 3+ years of hands-on experience deploying, configuring, and administering macOS systems, MacBooks, and related peripherals, including MDM (Iru, Workspace ONE), core enterprise SaaS and IT systems (Google Workspace, Slack, Okta), and network troubleshooting.
• 3+ years in a customer-facing support role, including white-glove technical support for executives or senior staff.
• Experience working tickets in ServiceNow or a similar ticketing system.
• Hands-on networking experience with Cisco Meraki, firewalls, managed switches, VLANs, and routers.
• Experience with conference room systems and A/V installations, including Zoom Rooms or similar platforms.
• Experience supporting business continuity and disaster recovery, including plan testing, backup and recovery, and restoring systems after a disruption.
• Experience working with a security team on access control, monitoring, vulnerability management, firewalls, and incident response.
• Experience using AI tools to streamline work, troubleshooting, and debugging.
