Design, deploy, troubleshoot, and optimize LAN/WAN and secure network topologies. Configure VPNs, firewalls, NAT, load-balancing, and monitoring tools. Collaborate with systems engineers, resolve complex network issues, and support 24/7 operations including hardware deployment worldwide.

Design, implement, and maintain secure system architectures; translate RMF control baselines into implementable security requirements; analyze vulnerability/scanning results and drive remediation; provide security engineering input for cloud, Zero Trust, containerization, and CI/CD; maintain security artifacts and tooling; mentor junior staff and support authorization (RMF) activities to strengthen enterprise security posture.

Perform technical security assessments and design secure networking, computing, and enclave environments. Serve as ISSE on engineering teams to implement IA architectures, support risk analysis and management, enforce trusted relationships, identify security requirements for government data, and recommend system-level mitigation strategies.

Design, evaluate, and secure complex LAN/WAN wired and wireless networks. Conduct site surveys and hardware installations, perform acceptance testing and throughput analyses, develop test harnesses, identify vulnerabilities, and produce system security documentation. Recommend hardware specifications, evaluate COTS/GOTS/GFE, and ensure systems meet government security requirements.

Administer and maintain Tenable Suite (Security Center, Nessus Scanners, Nessus Manager) on Linux, perform vulnerability scans and analysis, prioritize and remediate findings with IT teams, generate reports, monitor alerts and incidents, and provide training and status reporting to stakeholders.

Lead Splunk-based data collection, ingestion, and monitoring efforts. Troubleshoot and remediate system and data issues, deploy/manage Splunk add-ons and forwarders, implement role-based access, produce deployment and accreditation documentation, and ensure compliance with DoD C&A and security guidance.

Design, evaluate, and secure complex network and SIGINT hardware systems. Conduct onsite assessments, lead hardware installations, model solutions, create test interfaces, perform MTBF/MTTR analyses, evaluate LAN/WAN and wired/wireless networks, research COTS/GOTS, produce security documentation, and deliver vulnerability assessments and actionable recommendations.

Design, implement, and maintain secure systems in classified environments by integrating security throughout the SDLC. Lead RMF A&A activities to achieve and maintain ATOs, perform DISA STIG hardening and SCAP vulnerability assessments, automate compliance, support continuous monitoring, and coordinate remediation with development and infrastructure teams. Engage with customer security stakeholders and support incident response and forensic activities.

Lead design, deployment, and sustainment of Comply-to-Connect (C2C) solutions. Manage appliances, servers, and infrastructure; produce network architecture diagrams; evaluate upgrades; monitor and troubleshoot performance; support A&A and system accreditation; collaborate with cross-functional teams and customers to integrate and communicate technical requirements.

Design, build, and scale HSM-backed cryptographic and key-management services for large-scale cloud environments. Implement PKI, TLS, client-side encryption, TEEs, and Confidential VMs. Integrate identity (OAuth/SAML/Keycloak) and secure Google Workspace services. Ensure cryptographic lifecycle, compliance (FIPS), high availability, and support secure deployments across cloud APIs, OS, and hardware.
