About the role

  • Serve as a trusted, client-facing technical resource for escalated and complex support needs
  • Diagnose and resolve issues across Windows, macOS, Linux, Microsoft 365, Google Workspace, and mixed cloud/on-prem environments
  • Own issues end-to-end including investigation, resolution, documentation, and client communication
  • Support networking components such as firewalls, switches, VPNs, VLANs, DNS/DHCP, Wi-Fi, and routing
  • Partner with teammates in a non-tiered support structure that values collaboration and shared ownership
  • Participate in client projects including migrations, deployments, security initiatives, and system upgrades
  • Identify recurring issues and recommend automation, tooling improvements, or process changes
  • Maintain clear, accurate documentation and contribute to internal knowledge resources
  • Provide onsite support to NYC-area clients as needed

Requirements

  • 2–5+ years of experience in an MSP or fast-paced, multi-client IT support environment
  • Strong troubleshooting skills across systems, networking, cloud services, and security fundamentals
  • Customer-first mindset with the ability to communicate clearly and calmly with non-technical users
  • Comfort diagnosing unfamiliar technologies through logic, research, and experimentation
  • High ownership mentality — you don’t pass problems along, you solve them
  • Proactive approach to improving processes, documentation, and tooling
  • Desire to keep learning and expanding technical depth
  • Certifications (Microsoft, Cisco, CompTIA, etc.) are a plus but not required.
Benefits
  • Customer-focused support culture: Technical excellence paired with real client relationships
  • Non-tiered team structure: Ownership, autonomy, and accountability without rigid escalation paths
  • Variety and growth: Exposure to diverse environments that rapidly build skills
  • Impact-driven work: Your ideas for efficiency, automation, and improvement are encouraged and implemented
  • Supportive culture: Curious, collaborative teammates who value quality work and mutual respect
