About the role

  • We work hard and care about our most prized asset - our people.
  • We're helping businesses get off the ground by enabling them to focus on running their business.
  • We're data-driven and never stop iterating.

Responsibilities

  • Deliver senior-level, white-glove technical support to leadership and executives across Justworks.
  • Anticipate needs, troubleshoot discreetly under pressure, and serve as a trusted technical partner during high-visibility moments - board meetings, leadership offsites, executive travel, and live events.
  • Run and support new hire orientations for Phoenix and assist with orientations at other sites as needed.
  • Own the Phoenix onboarding experience end-to-end, ensuring new Justworkers have a smooth, polished first day.
  • Support the full asset lifecycle - procurement, onboarding deployments, decommissioning, and inventory audits - in partnership with the global IT team.
  • Partner with global IT, People, Workplace, and Security teams on initiatives that touch the employee experience - onboarding, offboarding, access reviews, and new tool rollouts.
  • Mentor peers on the IT Support team under the direction of the IT Support Manager.
  • Maintain clear, current documentation for Phoenix site operations, runbooks, and troubleshooting playbooks.
  • Identify recurring issues and partner with the IT Support Manager to scope and drive improvements that reduce ticket volume, improve resolution time, and elevate the employee experience.
  • Collaborate with the Workplace team to keep the physical IT environment (cabling, server room, workstations) in good working order.

Requirements

  • You bring sound judgment, professionalism, and the ability to navigate ambiguity without close oversight.
  • 5+ years of professional IT Support experience, including 2+ years supporting multiple offices or a distributed workforce.
  • Demonstrated experience providing white-glove technical support to executives and senior leadership in a high-visibility environment.
  • Proven track record of working independently as a senior IC - owning outcomes, exercising judgment, and operating without close oversight.
  • Advanced troubleshooting across macOS, Windows, mobile, and peripherals - including the ability to resolve complex, escalated issues.
  • Deep experience with MDM platforms (Jamf or Kandji for Mac; Intune or Airwatch for Windows).

Nice to have

  • Hands-on experience with Meraki-based environments (MX, MS, MR) and 802.1X authentication.
  • Familiarity with redundant or dual-ISP network architectures, including failover validation and ISP coordination.
  • Experience supporting corporate AV beyond Zoom Rooms - including DSP platforms (e.g., QSC Q-SYS), signal distribution and control systems (e.g., Extron), and wireless microphone systems (e.g., Shure).
  • Experience with network monitoring and zero-trust security tools (e.g., Datadog, Zscaler, Cloudflare WARP, or similar).
  • Scripting experience (Bash, PowerShell, Python).
  • Endpoint security tool familiarity (e.g., CrowdStrike, SentinelOne, Jamf Protect).
  • Experience supporting a new office buildout end-to-end.
  • Experience operating as a senior IC across a multi-site organization.
