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

--- Day-to-Day Tasks ---
1. Responsibilities include but not limited to the following:
2. Network Design and Architecture:
3. - Design, implement, and maintain robust and secure IT and OT
network infrastructures for transportation systems (e.g., traffic
management centers).
4. - Develop network architectures that integrate IT and OT
environments, ensuring seamless data flow and interoperability.
5. - Plan for network scalability, redundancy, and disaster recovery
to ensure continuous operation of critical transportation
services.
6. Network Implementation and Configuration:
7. - Install, configure, and manage network hardware (routers,
switches, firewalls, wireless access points, VPN concentrators)
and software.
8. - 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).
9. - Configure and maintain network security devices and policies,
including firewalls, intrusion detection/prevention systems
(IDS/IPS), and VPNs.
10. - Deploy and manage network monitoring and management
tools.
11. Network Operations and Maintenance:
12. - Monitor network performance, identify bottlenecks, and
troubleshoot network issues proactively.
13. - Respond to network incidents and outages, performing root
cause analysis and implementing corrective actions.
14. - Perform regular network maintenance, including
software/firmware updates and hardware replacements.
15. - Manage network configurations and documentation, ensuring
accuracy and completeness.
16. IT/OT Convergence and Security:
17. - Bridge the gap between IT and OT networks, understanding
the unique requirements and challenges of each.
18. - 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).
19. - Develop and implement network segmentation strategies to
isolate critical OT systems from IT networks.
20. - Conduct security assessments and vulnerability testing of
network infrastructure.
21. Collaboration and Support:
22. - Collaborate with cross-functional teams (e.g. business,
technical and security) to ensure network requirements are met.
23. - Provide technical guidance and support to operations staff.
24. - Participate in project planning, design reviews, and
implementation phases.
25. - Stay abreast of emerging technologies and industry trends in
IT, OT, and transportation systems.
26. Documentation and Reporting:
27. - Create and maintain detailed network diagrams, configuration
guides, and operational procedures.
28. - Generate reports on network performance, security incidents,
and project status.
