Original job description

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a CyberSecurity Engineer III based in the United States.

The CyberSecurity Engineer III will design, deploy, secure, and maintain mission-critical computing environments supporting government and defense operations. This role combines infrastructure engineering, cybersecurity, virtualization, and systems administration across on-premises and private cloud environments. You will work with enterprise VMware platforms, Linux and Windows systems, and network infrastructure to ensure secure, resilient, and reliable operations. A key part of your responsibilities will involve implementing security controls, remediating vulnerabilities, and maintaining compliance with federal cybersecurity standards. Working alongside infrastructure, networking, and cybersecurity specialists, you will contribute to complex technical initiatives and secure engineering solutions. This is an opportunity to apply advanced technical expertise to high-impact national security missions in a collaborative, innovation-driven environment. Accountabilities

As CyberSecurity Engineer III, you will support the engineering, administration, security, and sustainment of complex infrastructure environments while ensuring operational reliability and compliance with government security requirements.

• Design, deploy, configure, administer, and maintain secure computing infrastructure across on-premises and private cloud environments.

• Support the architecture and administration of enterprise VMware ESXi and vSAN virtualization platforms.

• Manage Linux and Windows Server environments, including Red Hat Enterprise Linux (RHEL), ensuring system availability, performance, and security.

• Implement, maintain, and remediate cybersecurity controls in accordance with NIST SP 800-53 Revision 4 and Revision 5 and DISA Security Technical Implementation Guides (STIGs).

• Automate system deployment, configuration, patching, and security hardening using tools such as Ansible, Jenkins, PDQ, WSUS, and related technologies.

• Identify, assess, track, and remediate system vulnerabilities using cybersecurity tools such as ACAS, Nessus, and Splunk to reduce infrastructure attack surfaces.

• Administer and support enterprise services and technologies, including Active Directory, databases, Veeam, VMware Horizon, Atlassian Suite, YUM repositories, and monitoring platforms.

• Design, maintain, and troubleshoot LAN/WAN and virtualized network infrastructure, including complex routing configurations involving OSPF and BGP.

• Collaborate with infrastructure, cybersecurity, networking, and software engineering teams to resolve technical challenges and implement secure, scalable solutions.

• Contribute to Authority to Operate (ATO) processes, including authorization packages, security documentation, control validation, compliance assessments, and security audits.

• Support infrastructure throughout its development, authorization, deployment, and operational lifecycle.

• Provide technical guidance and collaborate with other engineers to improve infrastructure security, automation, and operational efficiency.

Requirements

The ideal candidate combines extensive infrastructure engineering experience with strong cybersecurity knowledge and the ability to operate effectively in highly regulated, security-sensitive environments.

• At least 5 years of experience in infrastructure engineering, systems administration, network engineering, or a closely related technical field.

• Bachelor's or master's degree in a STEM discipline.

• Active U.S. Department of Defense Top Secret (TS) security clearance with SCI eligibility is mandatory. Candidates without an active clearance will not be considered.

• U.S. citizenship required, with no dual citizenship.

• Hands-on experience administering VMware ESXi and vSAN virtualization environments.

• Strong experience deploying, configuring, administering, and maintaining RHEL and Windows Server systems.

• Experience with infrastructure automation and Infrastructure as Code technologies, including Ansible, Terraform, or similar tools.

• Practical experience implementing and remediating security controls in accordance with DISA STIGs and NIST SP 800-53 requirements.

• Strong understanding of on-premises and private cloud architectures, enterprise virtualization, and secure infrastructure operations.

• Experience identifying, prioritizing, tracking, and remediating vulnerability backlogs in regulated or compliance-driven environments.

• Previous experience supporting government, defense, or other security-focused technical environments.

• Ability to collaborate effectively with infrastructure, networking, cybersecurity, and software engineering teams.

Preferred qualifications:

• Previous experience supporting government agencies or highly regulated organizations.

• Familiarity with LAN/WAN infrastructure, routing, switching, OSPF, and BGP.

• Experience with ACAS, Splunk, Nessus, Veeam, VMware Horizon, Dell Wyse, or comparable enterprise infrastructure technologies.

• Experience acting as a technical lead, mentoring junior engineers, or coordinating technical initiatives across multiple teams.

• Knowledge of DevSecOps practices and workflows in restricted or compliance-driven environments.

• Experience preparing ATO packages, conducting security control assessments, maintaining compliance documentation, or supporting cybersecurity audits.

• Familiarity with Jenkins, PDQ, WSUS, Active Directory, Atlassian Suite, YUM repositories, databases, and enterprise monitoring platforms.

Certifications:

• CompTIA Security+ certification, or ability to obtain it within 12 months of hire.

• CompTIA Network+ certification, or ability to obtain it within 12 months of hire.

• ITIL Foundation certification required.

• Additional DoD 8570 or DoD 8140 certifications are considered an advantage.

Benefits

• Competitive annual salary ranging from $120,000 to $180,000, negotiable based on experience, education, certifications, and business needs.

• Full-time remote working arrangement within the United States.

• Opportunities to work on mission-critical government and defense technology initiatives.

• Exposure to advanced cloud, infrastructure, cybersecurity, and virtualization technologies.

• Collaborative environment that encourages innovation, continuous learning, and knowledge sharing.

• Opportunities to work alongside experienced technical professionals on complex engineering challenges.

• Professional development opportunities and exposure to evolving cybersecurity and infrastructure practices.

• Domestic travel estimated at approximately 20%, primarily for customer engagements, technical coordination, and mission-related support.

• Potential opportunities to work at company offices or government facilities when required.
