Infrastructure/Systems Administration
CACI International Inc · Danbury, CT · 3 wk ago
OTHR$104k–$218k/yrFull-time
We need to output HTML fragment with sections: About the role, Responsibilities, Requirements (or Qualifications), Benefits, Pay, Schedule? Only include sections that have real specific content. The posting includes "The Opportunity" which is about the role. Could map to "About the role". Responsibilities section present. Qualifications section present. Benefits: there is description of benefits under "What You Can Expect" includes culture, etc. Also "Our broad and competitive mix of benefits options..." and list of benefits. So we can include Benefits section. Pay: there is "The Proposed Salary Range For This Position Is $103,800 - $218,100". So Pay section. Schedule: not mentioned. So omit Schedule.
We must not repeat job title as heading. Use for each section heading. Use
for each section heading. Use - for any list of duties/requirements/benefits. Use
for prose.
We need to preserve all substantive information, not invent or summarize away detail. Remove boilerplate: navigation, EEO, etc. Remove "Job ID / requisition numbers". Not present. Remove "CACI is an Equal Opportunity Employer..." etc. Remove "What You Can Expect" maybe we keep as part of Benefits? Actually "What You Can Expect" includes culture, trust, growth. Those are not benefits per se but could be considered part of Benefits? The instruction: include a section ONLY when posting has real, specific content for it. Benefits section: we have specific benefits list: healthcare, wellness, financial, retirement, family support, continuing education, time off benefits. Also mention flexible time off benefit, learning resources. So we can include Benefits with those details.
Pay: include the salary range.
We need to format responsibilities as list items. Qualifications as list? The qualifications includes required and desired. Could split into Required and Desired subheadings? But we only have
for section headings; we could have a Qualifications section with subheadings? Not allowed? We could just list all qualifications as list items, preserving required and desired. Could separate with
indicating Required and Desired. But we must not invent headings like "Required". Could use
for prose then
for list. Probably acceptable.
Let's extract responsibilities list:
- Administer multi-OS environments including Red Hat, Ubuntu, Windows, and macOS across servers and workstations.
- Troubleshoot infrastructure issues involving servers, storage, networking, and security in remote and on-site environments.
- Perform patching, package management, and compliance activities using tools such as Red Hat Satellite, Landscape, Foreman, MECM, or similar technologies.
- Manage identity and access services, including authentication and privileged access management using Centrify or comparable PAM solutions.
- Support AWS, Azure, VMware, Nutanix, or similar cloud and virtualization platforms.
- Collaborate with engineering, security, and support teams to resolve complex cross-platform infrastructure issues.
- Support a zero-trust security posture through system hardening, encryption, device controls, and security best practices.
- Support NIST compliance and security requirements within the IT environment.
- Utilize Splunk and related monitoring/logging technologies for system visibility, troubleshooting, and operational support.
- Develop, maintain, and improve technical documentation, procedures, and operational standards.
- Identify opportunities to improve infrastructure processes, tooling, automation, and service delivery.
- Evaluate IT requirements for internal, remote, and external customers and develop effective technical solutions.
- Independently manage assigned services and technologies while maintaining accountability for operational performance.
- Propose new ideas, challenge existing processes when appropriate, and contribute to continuous improvement initiatives.
Qualifications Required list:
- Bachelor's degree in Information Technology, Computer Science, or a related field, or equivalent experience.
- 5–7 years of hands-on Systems Administration experience supporting Linux and Windows environments.
- Working knowledge of at least 3–4 of the following areas:
- Patch/package management using Satellite, Landscape, MECM, Tanium, or similar tools.
- Identity and privileged access management using Centrify or similar PAM technologies.
- Scripting and automation using Bash, Python, PowerShell, or similar languages.
- Cloud platforms including AWS or Azure, or virtualization technologies such as VMware or Nutanix.
- Security hardening, encryption, endpoint security, or device-control technologies.
- Strong analytical, troubleshooting, and problem-solving skills.
- Ability to work independently with minimal supervision and take ownership of assigned technologies and services.
- Strong written and verbal communication skills with the ability to collaborate across technical, engineering, and support teams.
- Ability to create and maintain accurate technical documentation and operational procedures.
- Demonstrated ability to evaluate customer IT requirements and develop effective infrastructure solutions.
Desired Experience:
- Experience supporting a zero-trust architecture or security environment.
- Familiarity with containerization technologies, including Docker or Podman.
- Enterprise-level macOS administration experience.
- Familiarity with WinMagic SecureDoc or comparable full-disk encryption technologies.
- Exposure to device-control technologies such as USBGuard, DriveLock, or Microsoft Defender.
Benefits list:
- healthcare
- wellness
- financial
- retirement
- family support
- continuing education
- time off benefits
- flexible time off benefit
- robust learning resources
Also mention "culture of integrity", "environment of trust", "focus on continuous growth". Those are more cultural aspects; could be included in Benefits or maybe a separate section like "About the role"? But we already have About the role from "The Opportunity". Could incorporate those cultural points into About the role? The "What You Can Expect" section includes culture, trust, growth. Could be part of Benefits or maybe a separate section like "What You Can Expect". But we only have allowed headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Could put cultural aspects under Benefits? Might be okay but not exactly benefits. Could create a section "About the role" that includes the opportunity description and also the culture expectations. The "The Opportunity" paragraph: "CACI is seeking an Infrastructure/Systems Administrator to support a zero-trust research and development IT environment. The role supports a secure, compliant infrastructure integrating on-premises and cloud-based technologies across CACI programs. Provides hands-on administration and technical support across Linux, Windows, and macOS servers and workstations. Works collaboratively with Systems Administrators, engineers, and corporate IT teams to troubleshoot complex infrastructure issues and deliver reliable technical solutions. Contributes to continuous improvement, security hardening, compliance, documentation, and operational excellence."
That's good for About the role.
The "What You Can Expect" paragraphs about culture, trust, growth could be placed under Benefits? Might be a stretch. Perhaps we can create a section "About the role" and then after responsibilities and qualifications, we can have a Benefits section that includes the benefits list and also the cultural statements as prose. The instruction: "Prefer a few substantive sections over many thin ones." So we can combine cultural expectations into Benefits section as prose.
Thus final HTML:
