Role: Network/Security Engineer
Location: 500 McCullough Ave., San Antonio, TX / Remote
Duration: 6 months
Pay Rate: $50 W2
Top 3 Skills:
- Network
- Firewall
- Hybrid connectivity
- Virtualization
- Disaster recovery readiness support
Job Summary:
The Network Engineer supports a disaster recovery and virtualization strategy engagement by assessing network infrastructure, connectivity, firewall architecture, segmentation, and recovery dependencies. This role documents current-state findings, identifies risks and gaps, and helps develop practical recommendations, DR playbook inputs, and roadmap actions. The role is focused on assessment and planning; it does not include production network changes or live failover execution unless separately approved.
Key Responsibilities:
- Assess and document network architecture, connectivity, resiliency, and disaster recovery dependencies.
- Review routing, switching, WAN, VPN, DNS, DHCP, IP addressing, bandwidth, and inter-site connectivity considerations.
- Support discovery of virtualization, cloud, and hybrid network connectivity across VMware, Azure, OCI, and related environments.
- Assist with firewall and security architecture reviews, including segmentation, security zones, remote access, Zero Trust readiness, and monitoring integration.
- Identify network risks, failover constraints, operational gaps, and recovery limitations that could impact disaster recovery readiness.
- Document network paths, routing dependencies, firewall dependencies, and connectivity requirements that affect application and infrastructure recovery sequencing.
- Support development of target-state recommendations for secure recovery, segmentation, isolation, hybrid connectivity, and geographic resiliency.
- Contribute to DR testing and validation planning, including test scenarios, success criteria, failback considerations, reporting inputs, and remediation tracking.
- Help prepare network-related inputs for DR playbooks, recovery runbooks, escalation matrices, communication plans, and cyber recovery planning.
- Work with network, infrastructure, cloud, cybersecurity, application, and OT stakeholders to gather information and validate findings.
- Prepare clear documentation of findings, risks, assumptions, constraints, and recommendations for project deliverables and leadership review.
Required Qualifications
- Bachelor's degree in Information Technology, Cybersecurity, Computer Science, Network Engineering, or related field; equivalent experience may be considered.
- 5-7 years of experience in network engineering, network security, firewall administration, infrastructure support, or similar enterprise technology roles.
- Working knowledge of TCP/IP, DNS, DHCP, VPNs, routing, switching, WAN connectivity, IP addressing, segmentation, and troubleshooting.
- Experience supporting or assessing enterprise firewall platforms such as Palo Alto, Fortinet, Cisco, Check Point, or comparable technologies.
- Understanding of enterprise network architecture, including core/distribution/access layers, inter-site connectivity, resiliency, and failover design.
- Basic understanding of disaster recovery concepts such as RTO, RPO, dependency mapping, recovery sequencing, failover/failback, and DR testing.
- Ability to support assessments, stakeholder interviews, discovery sessions, data collection, and documentation reviews.
- Strong analytical, troubleshooting, written communication, and collaboration skills.
Preferred Qualifications
- Experience with hybrid cloud networking, including Azure and OCI connectivity concepts, cloud routing, and landing zone connectivity.
- Exposure to VMware virtual networking, software-defined networking, overlay/underlay design, micro-segmentation, and traffic flow analysis.
- Familiarity with OT network considerations, IT/OT segmentation, SCADA dependency awareness, and regulated operational environments.
- Experience supporting or documenting DR, backup, replication, cyber recovery, failover, validation, or recovery testing processes.
- Familiarity with Zero Trust architecture, privileged access, encryption, audit evidence, and security monitoring integration.
- Basic scripting or automation exposure using Python, PowerShell, Bash, Infrastructure-as-Code, or network automation tools.
- Relevant certifications such as CompTIA Network+, Security+, CCNA, Palo Alto, Fortinet, Cisco, VMware, Microsoft Azure, or similar credentials.
Technical Skills:
- Network architecture assessment
- SDN and micro-segmentation readiness
- Routing, switching, WAN, VPN, DNS, DHCP, and IPAM
- Zero Trust network architecture awareness
- Firewall architecture and policy review
- DR dependency mapping
- Network segmentation and security zoning
- Network resiliency and failover assessment
- Hybrid cloud connectivity: Azure and OCI
- Recovery sequencing support
- VMware virtual networking concepts
- DR testing and failback planning support
- Overlay/underlay network design
- Documentation of findings, risks, gaps, and recommendations
- Disaster Recovery Knowledge Expectations
The candidate should understand how network design and dependencies influence recovery readiness. The role should be able to support:
• Identification of network dependencies that impact application, infrastructure, and data recovery.
• Evaluation of resiliency, failover capabilities, and inter-site connectivity as part of DR readiness.
• Documentation of segmentation, isolation, and secure recovery considerations for IT, OT, and regulated environments.
• Support for DR testing frameworks, tabletop exercises, cloud failover validation, cyber recovery scenarios, and failback planning.
• Contribution to DR playbooks, recovery runbooks, validation procedures, escalation matrices, and communication frameworks.
Soft Skills:
• Attention to detail and documentation discipline.
• Structured problem-solving mindset.
• Clear verbal and written communication.
• Time management and ability to work in a project-based environment.
• Ability to work across network, security, infrastructure, cloud, application, and OT teams.
