# Network Specialist - Job Description & Qualification Tasks **Primary Responsibility:** To engineer and support the robust and secure IP network infrastructure for Building Automation Systems (BAS), ensuring seamless integration with client IT environments and reliable remote access. **Prerequisites:** - Completion of Field Specialist role with supervisor sign-off - Completion of Bridge Training modules - Minimum 18-24 months experience as Field Specialist - OSHA 40-Hour Construction Safety Certification (maintained) **Estimated Time in Role Before Promotion Eligibility:** 24-36 months **Next Possible Roles:** [[training-structure/roles/senior-field-operations-coordinator]](Dispatch) --- ## Assessment Methods - Practical demonstrations with supervisor observation and sign-off on each key task - Network design documentation reviewed by senior engineers - Successfully deployed networks with zero critical security vulnerabilities - Written exam on networking protocols and cybersecurity (80% passing score) - Client IT team feedback and acceptance of integration work - Troubleshooting case studies with documented resolution steps - Portfolio of network diagrams, documentation, and completed integration projects --- **Key Tasks for Qualification** - 1. **Network Design & Configuration:** Design a network architecture for a large-scale BAS deployment, including IP address schemes, subnet masks, and VLAN segmentation. - 2. **Network Design & Configuration:** Configure and commission managed switches (e.g., Cisco, Dell) to establish specific VLANs for BAS devices, isolating them from the main corporate network. - 3. **Security & Remote Access:** Implement secure remote access methods (e.g., VPNs, secure proxies) for BAS controllers and head-end servers. - 4. **Security & Remote Access:** Harden a BAS server by disabling unnecessary services, configuring firewalls, and enforcing strong password policies. - 5. **Troubleshooting & Documentation:** Diagnose and resolve complex network communication failures (e.g., BACnet/IP broadcast storms, IP conflicts, device timeout errors). - 6. **Troubleshooting & Documentation:** Create detailed network documentation (diagrams, IP lists, port mapping) for a completed project handover package. - 7. **IT Integration:** Successfully coordinate the integration of a new BAS server with a client's IT team, adhering to their security and naming conventions. --- ## Required Training Course List 1. **BAS Network Architecture and Design:** IP Address Schemes, Subnetting, VLANs, and Segmentation Best Practices. 2. **Managed Switch Configuration:** Vendor-specific training (e.g., Cisco/Dell) on VLAN creation and port configuration. 3. **Secure Remote Access Implementation:** Setting up and managing VPNs, secure proxies, and access control lists (ACLs). 4. **Server Hardening and BAS Cybersecurity:** Implementing firewalls, disabling services, and enforcing strong security policies. 5. **Network Troubleshooting for BAS Protocols:** Diagnosing BACnet/IP, Modbus, and general TCP/IP communication failures. 6. **Technical Documentation Standards:** Creating network diagrams, IP lists, and handover documentation packages. 7. **IT/OT Collaboration and Client Integration:** Procedures for working with client IT teams and adhering to corporate IT standards. 8. **Network Monitoring and Management Tools:** Using Wireshark, PING, traceroute, and BAS-specific diagnostic tools. --- ## Optional/Advanced Training - CompTIA Network+ Certification - Cisco CCNA Certification - Cybersecurity fundamentals (CompTIA Security+) - Advanced firewall configuration (pfSense, Fortinet, etc.) - Wireless network design for BAS applications - Enterprise network management systems - Cloud-based BAS platforms and integration - IPv6 implementation and migration strategies --- ## Cross-Training Opportunities - Shadow Programmer Developers to understand control communication requirements - Shadow Graphic Developers to understand HMI network dependencies - Attend IT industry conferences or webinars on OT/IT convergence - Work with Project Managers on network infrastructure estimation and planning - Collaborate with Field Specialists on network troubleshooting field calls - Review Service Fusion workflows for tracking network equipment and licenses - Participate in client IT coordination meetings --- ## Qualification Checklist Before advancing to Senior Field Operations Coordinator, the Network Specialist must demonstrate: - [ ] Design and deploy 5+ complete BAS networks from scratch - [ ] Configure 10+ managed switches with proper VLAN segmentation - [ ] Implement secure remote access for 5+ different client environments - [ ] Successfully integrate with 5+ different client IT departments - [ ] Harden 3+ BAS servers to meet enterprise security standards - [ ] Diagnose and resolve 20+ complex network communication issues - [ ] Create comprehensive network documentation for 10+ projects - [ ] Pass written exam on networking and cybersecurity (80%+) - [ ] Obtain at least one industry-recognized networking certification (Network+, CCNA, or equivalent) - [ ] Maintain zero critical security incidents over 24-month period - [ ] Mentor Field Specialists on basic networking concepts - [ ] Receive supervisor sign-off on all 7 key qualification tasks --- ## Timeline Expectations **Typical Duration:** 24-36 months - Months 1-6: Learning network fundamentals, working under senior Network Specialist supervision - Months 7-12: Designing networks with oversight, gaining switch configuration proficiency - Months 13-18: Managing client IT integrations, advanced security implementation - Months 19-30: Full independence on network projects, pursuing certifications - Months 31-36: Mentoring others, preparing for dispatch coordinator responsibilities **Note:** Progression depends on demonstrated technical expertise, successful client IT collaborations, certification achievement, and company need for dispatch coordinator capacity. ## Recommended Videos -
