• Client environments show measurable improvement in uptime, performance, and security posture through your remediation work and infrastructure recommendations.
• Technical projects (migrations, upgrades, security initiatives) are delivered on time with minimal disruption, and your input is sought in scoping and planning.
• Tickets are well-documented, response times are reliable, and clients consistently report positive experiences with your communication and follow-through.

• Working knowledge of cybersecurity practices including vulnerability management, security scanning and remediation, and general security and compliance concepts.
• Strong vigilance, attention to detail, and a practical problem-solving mindset, with a security-first, team-oriented work ethic and the ability to manage remote and on-site client needs.
