Network Engineer

Overview

The Network Engineer will provide advanced engineering and operational support to design implement and optimize enterprise network infrastructure in support of OIM internal services and SC mission systems. This role spans the full lifecycle of network systems balancing high-level architecture and design responsibilities with day-to-day administration troubleshooting and device configuration.

The Network Engineer must apply industry best practices SC-approved lifecycle methodologies and DOE cybersecurity requirements to ensure resilient scalable and secure connectivity across cloud on-premise and hybrid environments.

Key Responsibilities

• Network Infrastructure Management: Administer and maintain a multi-site enterprise network including routers switches firewalls VPNs wireless infrastructure and load balancing technologies.
• Architecture and Design: Develop scalable and resilient network architectures that support high availability fault tolerance and future growth aligned with DOE enterprise IT strategy and security policies.
• Routing and Protocol Engineering: Engineer and support complex routing strategies using EIGRP OSPF and BGP; ensure optimal route redistribution convergence and path selection across hybrid connectivity models including DMVPN and MPLS.
• Firewall and Security Integration: Implement and manage next-generation firewall platforms (e.g. Palo Alto) including high availability configuration SSL decryption policy optimization IDS/IPS tuning and integration with cloud and on-premises security architectures.
• Cloud and Hybrid Networking: Design deploy and manage hybrid network topologies within Microsoft Azure including VNets ExpressRoute peering NAT Gateway and firewall solutions to ensure secure and performant cross-premise connectivity.
  Network Access Control (NAC): Support the implementation and management of NAC solutions such as Cisco ISE with potential integration to Microsoft Intune for endpoint compliance and identity-based access control.
• Project Leadership: Lead infrastructure modernization initiatives including planning implementation and validation of new networking technologies or re-architecture of existing environments.
• Monitoring and Performance Optimization: Utilize tools such as Cisco Catalyst Center SolarWinds and Azure Network Watcher to monitor availability perform root cause analysis and implement performance enhancements.
• Documentation and Standards Compliance: Maintain accurate technical documentation including topology diagrams configuration baselines IP address management and change control records to support audit readiness and operational continuity.
• Cross-Functional Collaboration and Mentorship: Partner with adjacent IT disciplinesincluding cloud systems and securityto deliver integrated solutions; provide mentorship and technical leadership to junior staff.
• Serve as the primary interface between OIM and network engineering functions across SC.
• Conduct Alternatives Analysis (AA) and Cost-Benefit Analysis (CBA) for emerging network technologies modernization projects or proposed architectural changes.
• Provide engineering oversight for assigned network projects ensuring timely coordination risk mitigation and issue escalation.
• Ensure consistent delivery of network engineering products aligned with SC lifecycle methodology including forms checklists review templates and acceptance documentation.
• Act as an escalation resource for advanced troubleshooting of complex network issues.
• Provide support during major outages or degraded services requiring increased coverage or coordination.
• Participate in scheduled patching upgrades and maintenance events including planning and backstop coverage.
• Lead the evaluation of new and emerging network technologies for applicability to SCs enterprise environment.
• Provide subject matter expertise to OIM leadership in support of network architecture decisions policy formulations and modernization strategies.
• Drive innovation initiatives that enhance scalability resilience and security of SCs network infrastructure.

Required Qualifications

• Bachelors degree in Information Technology or related field.
• Minimum of 7 years of relevant network engineering experience.
• US Citizen with the ability to obtain an agency clearance
• Certifications (Required):
  • Cisco CCNP (Routing & Switching or Enterprise)
