Sr. Network Engineer with Transportation Systems

About the Role

The incumbent will act as Senior Network Architect/Engineer for the DOT Transportation Safety Management and Operations (TSMO) Technology Program. This role involves building and maintaining secure, reliable, and performant communication pathways that enable the integration and operation of both IT and OT systems, ensuring smooth data flow and protection of critical industrial infrastructure. The position is critical in designing, building, and securing infrastructure from evolving cyber threats while ensuring the safety, reliability, and efficiency of transportation networks.

Responsibilities

• Network Design and Architecture:
  • Design, implement, and maintain robust and secure IT and OT network infrastructures for transportation systems (e.g., traffic management centers).
  • Develop network architectures that integrate IT and OT environments, ensuring seamless data flow and interoperability.
  • Plan for network scalability, redundancy, and disaster recovery to ensure continuous operation of critical transportation services.
• Network Implementation and Configuration:
  • Install, configure, and manage network hardware (routers, switches, firewalls, wireless access points, VPN concentrators) and software.
  • Implement and manage network protocols relevant to both IT (TCP/IP, BGP, OSPF) and OT (Modbus, DNP3, IEC 60870-5-101/104, Profinet, EtherNet/IP).
  • Configure and maintain network security devices and policies, including firewalls, intrusion detection/prevention systems (IDS/IPS), and VPNs.
  • Deploy and manage network monitoring and management tools.
• Network Operations and Maintenance:
  • Monitor network performance, identify bottlenecks, and troubleshoot network issues proactively.
  • Respond to network incidents and outages, performing root cause analysis and implementing corrective actions.
  • Perform regular network maintenance, including software/firmware updates and hardware replacements.
  • Manage network configurations and documentation, ensuring accuracy and completeness.
• IT/OT Convergence and Security:
  • Bridge the gap between IT and OT networks, understanding the unique requirements and challenges of each.
  • Implement and enforce cybersecurity best practices for both IT and OT environments, adhering to relevant industry standards (e.g., NIST Cybersecurity Framework, ISA/IEC 62443).
  • Develop and implement network segmentation strategies to isolate critical OT systems from IT networks.
  • Conduct security assessments and vulnerability testing of network infrastructure.
• Collaboration and Support:
  • Collaborate with cross-functional teams (e.g., business, technical, and security) to ensure network requirements are met.
  • Provide technical guidance and support to operations staff.
  • Participate in project planning, design reviews, and implementation phases.
  • Stay abreast of emerging technologies and industry trends in IT, OT, and transportation systems.
• Documentation and Reporting:
  • Create and maintain detailed network diagrams, configuration guides, and operational procedures.
  • Generate reports on network performance, security incidents, and project status.

Requirements

• 12+ years of experience designing and implementing computer and information networks, such as LAN, WAN, intranets, extranets, and other data communications networks, including network modeling, analysis, and planning.
• 72 months of experience in foundational IT and OT networking, including:
  • Networking protocols (routing, switching, and wireless protocols).
  • Network design and architecture.
  • Network security principles.
  • Network monitoring and troubleshooting.
• 72 months of experience in designing, building, securing, and managing IT and OT networks, with a focus on IT/OT convergence challenges and solutions, preferably in the transportation sector.
• 60 months of experience in OT, including:
  • Network protocols.
  • Cybersecurity threats and vulnerabilities.
  • IT/OT convergence challenges.
  • Real-time data processing and management.
• 60 months of experience with the specific network needs of transportation sector technologies, such as:
  • Adaptive traffic signal control.
  • Safety and reliability standards.
  • Intelligent Transportation Systems (ITS).
  • Advanced Traffic Management Systems (ATMS).
• 60 months of experience with IT and OT network operational support, including incident response and root cause analysis.
• 48 months of experience with cybersecurity specific to IT/OT convergence, including:
  • Implementation of layered security approaches.
  • Compliance with regulations and standards.
  • Zero-trust architecture and implementation.
• 48 months of experience collaborating with cross-functional teams (business, technical, and security) and producing both written and verbal communication articulating secure networking concepts to technical and non-technical audiences.
• Must hold at least one of the following certifications:
  • Cisco (CCNA, CCNP, CCIE).
  • CompTIA Network+/Security+.
  • CISSP.
• Copy of candidate identification (e.g., Driver’s License, Green Card, Visa, and Passport if applicable).
• Copies of any documents referenced in the qualifications (e.g., professional certifications, degrees).
