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, Ether Net/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.
