This is a hands-on, senior individual contributor role focused on identity, SaaS platforms, device management, automation, and security in a fast-growing, global company.

  • Assist with networking and infrastructure initiatives (Meraki, Cisco)
• Operational Excellence
  • Lead and execute IT projects from design through delivery
  • Provide Tier-3 level troubleshooting and escalation support
  • Create and maintain high-quality documentation, runbooks, and knowledge base articles
  • Participate in a rotating on-call schedule
  • Ability to travel between company offices on an as-needed basis to support infrastructure projects, deployments, and on-site initiatives, including office buildouts, technology setups, and the resolution of complex on-site issues
  • Perform other duties as assigned, consistent with the role

Experience

• 5+ years in a similar role in a growing or enterprise environment
• Experience supporting 1,000+ end users across multiple locations

Security & Architecture

• Experience applying security frameworks in day-to-day operations
• Comfortable balancing security requirements with user experience

Project & Communication Skills

• Demonstrated success leading IT projects (email migrations, SaaS rollouts, VoIP, security initiatives)
• Excellent communication skills with both technical and non-technical audiences
• Clear documentation and structured problem-solving approach
• The position requires a balance of proactive project work and reactive support, with the flexibility to pivot between long-term initiatives and immediate technical issues

Nice to Have
