System Administrator Level 2

IT Solutions of South Florida • Hypoluxo, FL, US

Love building reliable networks, solving IT puzzles, and helping businesses keep their environments secure? Excited to grow your skills in a supportive environment while gaining hands-on experience with networking, cloud, cybersecurity, and compliance-focused technologies?

So are we.

We’re IT Solutions of South Florida, and we’re looking for a Level 2 System Administrator who’s ready to expand their experience across networking, cloud, security, and cybersecurity compliance. You’ll work closely with senior engineers, assist with client projects, and provide day-to-day technical support that makes a real impact.

This role also supports clients with increasing cybersecurity and regulatory requirements, including environments aligned with NIST SP 800-171, CMMC, CIS Controls, CIS Benchmarks, and other security best practices. You don’t need to be a compliance auditor, but you should understand how technical controls, secure configurations, documentation, and remediation activities contribute to a compliant and secure environment.

What You'll Do

• Provide remote and on-site support: install, configure, maintain, and troubleshoot hardware and software, including operating systems, office applications, servers, endpoints, and networking devices.

• Monitor system performance, availability, and security and troubleshoot system and security-related errors.

• Provide technical support for end users — leveraging AI-assisted tools to diagnose issues faster and deliver better outcomes.

• Implement policies, procedures, security standards, and technical best practices to maintain the security and reliability of client environments.

• Assist with the implementation and remediation of technical cybersecurity controls associated with NIST SP 800-171, CMMC, CIS Controls, CIS Benchmarks, and related security frameworks.

• Assist with security hardening of Microsoft 365, Windows endpoints, servers, firewalls, switches, and other infrastructure components.

• Support security technologies including MFA, Conditional Access, Microsoft Defender, endpoint protection, encryption, secure configurations, vulnerability remediation, logging, and access controls.

• Assist senior engineers with identifying and remediating cybersecurity vulnerabilities, configuration weaknesses, and compliance gaps.

• Work with vendors and partners to resolve technical and cybersecurity-related issues.

• Assist with deploying and maintaining switches, routers, firewalls, VPNs, and segmented networks.

• Support cloud environments including Microsoft 365, Azure, and AWS with configuration, administration, security, and troubleshooting.

• Create and maintain high-quality technical documentation, network diagrams, configurations, procedures, and evidence supporting cybersecurity and compliance requirements.

• Collaborate with senior engineers on larger projects including migrations, upgrades, security remediation initiatives, CMMC/NIST-aligned projects, and AI-adjacent rollouts such as Copilot, Claude deployments, and automation workflows.

• Participate in vulnerability remediation, system hardening, security assessments, and implementation of recommended security controls.

• Continue developing your technical and cybersecurity skills through training, mentorship, certifications, and staying current with emerging technologies and threats.

Who You Are

• 3+ years of relevant IT, systems administration, networking, or cybersecurity experience. MSP experience is a plus.

• Strong troubleshooting skills and a customer-first mindset.

• Comfortable working independently while knowing when to escalate or collaborate with senior technical resources.

• Local to Palm Beach County; this is an in-person role.

• Curious, adaptable, security-conscious, and calm under pressure.

• Interested in continuing to develop your knowledge of cybersecurity, cloud technologies, and compliance requirements.

• Able to understand that security is part of everyday systems administration — not something handled only by the security team.
