Security & Reliability
- Maintain a security-first mindset across identity, endpoints, SaaS, and access controls
- Support and improve endpoint and infrastructure security (SentinelOne, Qualys, RBAC models)

- 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
