DKW Communications, Inc – NOAA Affiliate Apr 21 – Current

Lead Telecommunications/Communications Integration Engineer

Ensure that the network solution complies with federal, NOAA, and NWS requirements include, but not limited, to baseline secure configuration, network security hardening,

Network security monitoring, network encryption, redundant connections, optimized Network configuration, right sizing network bandwidth, Managed Trusted Internet Protocol Service/Trusted Internet Connections, and integration of cloud hosting providers to the network infrastructure where required.

Directly aid the NWS EIS transition team in the creation of the NWS specific EIS Transition. Provide recommendations and update, as necessary, the NWS’s EIS transition plan to include, but not limited to, network redesign to move from Lumen & Verizon WANs to a single AT&T WAN, the management of network bandwidth, Quality of Service (QoS), tracking of decommission activities, opportunities for modernization, and evaluate new services/capabilities.

Review any proposed EIS service and system designs to ensure they are properly configured to the NWS’s technical and network security requirements.

Review business processes and provide recommendations on what is needed for seamless integration between each of the NWS service providers.

Review the NWS’s telecommunications infrastructure to obtain a deep understanding of the current functionality and their inventory.

Review the portions of the National Oceanic and Atmospheric Administration (NOAA) EIS RFP and AT&T’s awarded proposal that apply to NWS’ services. Document any areas of concern with regards to the proposed transition period to include, but not limited to, any areas that may have been missed between the RFP/RFQ and quote and any areas where proposed modernization (i.e., TDM to Ethernet circuits, SD-WAN, etc.) could occur sooner with limited impact to the accepted agency transition plan.

Conduct system architecture and configuration reviews as new, changed, improved, or modernized versions of EIS services are provided by the awarded EIS contractors.

Verify and analyze existing network architecture and configurations as well as redesign and implement a new network solution that supports the NWS’s long-haul telecommunications, Wide Area Network (WAN), Local Area Network (LAN), connectivity to NOAA and other business partners, The NWS WAN Customer Edge is primarily leveraging Cisco routers and equipment. There are some instances where Juniper routers and firewalls are leveraged within the NWS WAN

Coordinate directly with the NWS team on the circuit priorities. NWS has several large, expensive circuits that they will look to transition firs.

Ensuring that a best practice, repeatable design is implemented and that the changes limit or eliminate disruption will be extremely important to maintain NWS services during this transition.
