Job Description

Network Security Engineer Direct Hire 100% Onsite - Downtown Las Vegas, NV Overview We are seeking a mid-level Network Security Engineer with a strong foundation in network engineering and security controls, and a solid working understanding of core systems and infrastructure. This role is ideal for someone who comes from a firewall, network security policy, or NAC background and understands how changes to network and security controls impact the broader IT environment. The Network Security Engineer will focus on the design, implementation, and operation of network security technologies, while partnering closely with systems, infrastructure, and application teams. A disciplined approach to change control, documentation, and production stability is critical. Exposure to SIEM and vulnerability management is required, though this role is not intended to be a senior security architect position. Key Responsibilities Network & Systems Integration (Security-Focused)

• Support and maintain secure network environments with an understanding of how network, systems, and identity platforms integrate.
• Evaluate the downstream impact of network and security changes on servers, applications, and end-user access.
• Partner with systems and infrastructure teams to ensure network security controls align with operational requirements.

Firewall & Network Security Engineering

• Troubleshoot complex traffic flow and policy-related issues across segmented environments.
• Enforce disciplined change control, documentation, and peer review for firewall and network security changes.

Network Access Control (NAC)

• Support and evolve network access control solutions (Aruba ClearPass or similar).
• Participate in the evaluation and potential replacement of ClearPass, including requirements gathering, architecture input, and implementation support.
• Manage device authentication, posture enforcement, and segmentation across wired and wireless networks.

Security Operations Enablement

• Support the operation and integration of security platforms such as SIEM, EDR/XDR, vulnerability management, MFA, and email security, with a strong understanding of how these tools interact with infrastructure.
• Assist with alert triage, investigation, and escalation of security events in coordination with internal teams and external SOC partners.
• Help translate security requirements into practical, implementable infrastructure controls.

Change Management, Documentation & Standards

• Drive strong change management practices, ensuring infrastructure and security changes are well-documented, tested, and approved.
• Develop and maintain technical documentation, SOPs, runbooks, and architecture diagrams.
• Support audits, risk assessments, and compliance initiatives by providing technical evidence and system knowledge.

Required Qualifications

• Strong understanding of networking fundamentals (TCP/IP, routing, switching, DNS, VPNs, segmentation, zero-trust concepts).
• Hands-on experience with firewall rule management and network security policies.
• Working knowledge of server and systems infrastructure, including operating systems, virtualization, and core services.
• Experience supporting or interacting with SIEM platforms and vulnerability scanning tools, including basic alert review and remediation coordination.
• Familiarity with formal change control processes in production environments.
• Strong troubleshooting, documentation, and communication skills.

Preferred Experience

• Experience with Palo Alto firewalls.
• Experience with Aruba ClearPass or other NAC solutions.
• Familiarity with SIEM, EDR/XDR, vulnerability management, MFA, and email security platforms.
• Experience supporting or collaborating with a Security Operations Center (SOC).
• Scripting or automation experience (PowerShell, Python, APIs) is a plus.

Education & Experience

• 3-5 years of hands-on experience in network engineering, network security, or security operations, with an emphasis on network security.
• Experience working in enterprise or regulated environments is strongly preferred.
• Associate degree in Computer Science, Information Systems, Cybersecurity, or related field preferred; Bachelor's degree is a plus.

Certifications (Preferred, Not Required)

• Security+, Network+, CySA+, SSCP, GSEC
