The successful candidate works independently with minimal guidance, takes initiative to expand and improve monitoring coverage, and communicates monitoring information effectively to technical teams and leadership.

The position maintains the Nagios XI platform and its health, expands monitoring as infrastructure grows, builds and maintains custom checks, and tunes alerts to detect genuine issues while reducing false positives. It also involves monitoring platform performance, documenting configurations and processes, collaborating with IT, network, systems, and application teams, and evaluating plugins, integrations, and automation opportunities. A bachelor's degree in a relevant field or equivalent practical experience is required. The role may require eligibility for U.S. Government authorizations related to access to export-controlled commodities and technology.

• Ability to work independently with minimal oversight and take initiative.
• Strong communication skills, including the ability to explain technical monitoring data to other teams and leadership.
