Security Systems Administrator Jobs in Colorado (NOW HIRING)

Systems Administrator

The Denver Foundation is seeking a hands-on, technically capable Systems Administrator to join our IT team. This is a full-time, exempt position with a starting salary of $96,000-$108,000 per year, depending on experience.

This is an ideal opportunity for a strong mid-level Systems Administrator who enjoys taking ownership of systems and infrastructure, solving problems independently, and working across a broad technology environment.

This is not primarily a help desk role, and it is not intended to be a senior engineering, architecture, or management position. We are looking for someone who can independently manage day-to-day systems operations while identifying opportunities to improve reliability, security, efficiency, and the overall technology experience.

What You'll Do

Systems & Identity Administration

• Administer and maintain Windows Server and Linux systems.
• Manage Active Directory / Entra ID, DNS, DHCP, Group Policy, and file services.
• Manage system patching, updates, configurations, and system health.
• Perform preventive maintenance and troubleshoot complex system issues.
• Maintain accurate system documentation and standard configurations.

Endpoint & Device Management

• Manage Windows endpoints using Intune and/or SCCM.
• Oversee device enrollment, imaging, application packaging, and updates.
• Maintain device compliance, security baselines, and standard configurations.
• Troubleshoot escalated endpoint issues and partner with the Service Desk when needed.

Network & Infrastructure

• Support network infrastructure including firewalls, switches, wireless, and VPN.
• Monitor system and network performance and troubleshoot connectivity issues.
• Coordinate with vendors for infrastructure support and maintenance.
• Maintain network and infrastructure documentation.

Cloud & Productivity Platforms

• Administer Microsoft 365, Google Workspace, and other SaaS platforms.
• Manage accounts, licenses, groups, permissions, and access controls.
• Support secure configuration and rollout of new tools and features.
• Troubleshoot email, collaboration, file storage, and other productivity-platform issues.

Security, Backup & Reliability

• Support endpoint protection, MFA, and foundational security controls.
• Manage backup operations and perform periodic restoration testing.
• Support disaster recovery and business continuity readiness.
• Participate in access reviews, audits, and security improvement initiatives.

Projects & Continuous Improvement

• Maintain system documentation, diagrams, inventories, and procedures.
• Independently plan and execute small- to medium-sized infrastructure projects.
• Identify opportunities to improve reliability, efficiency, security, and user experience.
• Partner with IT leadership and other teams on technology improvements.
• Support the secure configuration and responsible use of AI-enabled tools.

What We're Looking For

The ideal candidate will have approximately 3-7 years of experience in systems administration, infrastructure, or IT operations and be comfortable personally administering a variety of business-critical systems.

Required Qualifications

• 3-7 years of experience in systems administration, infrastructure, or IT operations.
• Hands-on experience administering Windows Server.
• Hands-on experience with Active Directory and/or Entra ID.
• Experience managing Windows endpoints using Intune and/or SCCM.
• Experience administering Microsoft 365 in a business environment.
• Working knowledge of networking infrastructure and concepts, including firewalls, switches, VPN, and Wi-Fi.
• Familiarity with virtualization technologies such as VMware or Hyper-V and backup systems.
• Strong troubleshooting, analytical, and problem-solving skills.
• Demonstrated ability to independently prioritize work and take ownership of operational outcomes.
• Strong organization, documentation, and follow-through.
• Ability to communicate technical concepts clearly to non-technical audiences.
• Strong customer-service orientation.
• Ability and willingness to learn new technologies independently.
• Authorized to work in the United States.

Preferred Qualifications

• Linux server administration experience.

• Experience supporting security or compliance initiatives.
• Experience with data classification, security, governance, or compliance platforms.
• Experience supporting new technology implementations.
• Experience configuring or managing enterprise AI tools.

AI experience is a plus, but it is not a substitute for strong core systems and infrastructure experience.

The Ideal Candidate

• Enjoys owning and maintaining systems.
• Can move comfortably between servers, identity, endpoints, cloud platforms, networking, and troubleshooting.
• Takes initiative rather than waiting to be told what needs attention.
• Investigates problems thoroughly and follows them through to resolution.
• Thinks proactively about system reliability, security, and prevention.
• Documents their work and values consistent processes.
• Can prioritize competing operational needs.
• Knows when to solve an issue independently and when to involve IT leadership or a vendor.
• Communicates effectively with both technical and non-technical colleagues.
• Is curious and comfortable learning technologies they haven't worked with before.
• Values reliability and service as much as technical sophistication.

What We Offer

• Paid time off
• Retirement plan contributions
• Tuition assistance
• Medical insurance
• Life insurance
• Disability insurance

Why Join The Denver Foundation?
