Systems Administrator Cover Letter Template

Dear Hiring Manager, I’ve kept our last on-call cycle running smoothly for the last 18 months, resolving issues before they hit users. At [Previous Company], I turned around a snag where a failing rack switch was causing intermittent outages across three data halls, cutting downtime by about 40 hours a quarter. I fixed the hardware path, rerouted traffic, and added monitoring so we spotted similar faults earlier. I’m looking to bring that methodical approach to [Company Name]. In this role I’d lean on hands-on OS and server management, backup and recovery planning, and capacity monitoring to keep systems stable. I’m comfortable with Windows and Linux, familiar with patching cycles, and I document changes so the team can follow the same steps next time. I’m also used to writing clear procedures and helping teams interpret logs and alerts without getting bogged down in jargon. One story that stands out is a mid-week storage array fault that tripped alerts across multiple tenants. I coordinated with storage, network, and apps teams, restored services from a recent backup, and implemented a short-term workaround to avoid further impact. The incident ended with a post mortem that led to a revised runbook and a permanent monitoring tweak, so we now catch similar patterns quickly and accurately. I’m available to discuss how my background fits [Company Name] and the Systems Administrator role. If you’d like to chat, I’m happy to arrange a time. Kind regards, [Your Name]
