Title: Enhanced Communication Gateway Systems (ECGS) Subject Matter Expert (SME)

Location: Arlington, VA / Pentagon

Clearance: TS/SCI

NetCentrics is a market leader in cybersecurity, enterprise IT, and telecommunications solutions and services. We serve the DoD, DHS, Federal Civilian Agencies, and Intelligence Community. We are a diverse group of intellectually curious people living by our core values while bonded by the shared mission to secure our nation - join us!

You will serve as the Enhanced Communication Gateway Systems (ECGS) Subject Matter Expert (SME) for the NetCentrics information technology (IT) support efforts for the Defense Information Systems Agency (DISA) Joint Service Provider (JSP). You will provide SME support to a customer-focused organization that provides, manages, operates, and maintains IT shared services for the Pentagon and select agencies and organizations in the National Capital Region (NCR). The JSP performs a wide variety of enterprise support functions in order to meet service requirements. These functions may include server hosting, in which the hardware, software, infrastructure, and maintenance required to host the customer-managed applications are in a consolidated, virtualized environment where JSP manages the server environment up to the operating system and provides operational monitoring and facility support for the Operations (OPS) consolidated server rooms (CSRs). The JSP also supports the DISA Organizational Messaging Service (OMS) which enables organizations to exchange both classified and unclassified information with other organizations within the DoD, other United States (US) Government agencies, Five Eyes countries (US, Canada, United Kingdom, Australia and New Zealand), the 28 North Atlantic Treaty Organization countries, and all countries with US military bases or embassies worldwide.

The ECGS SME shall perform operations and system administration tasks as defined below for the large and small scale ECGS systems (references the complete ECGS system and a tailored version called Mini ECGS) operated at primary and alternate site locations. Both large and small ECGS systems integrate and utilize common system components to include Mailroom, thick client and web-based system application management tools (e.g. Service Desk), Microsoft SQL, Microsoft Internet Information Services (IIS), and internal Protogate Communications boards. Only large-scale ECGS systems implement high availability through the use of Microsoft Clustering Technology to provide automated failover between single site ECGS application cluster nodes located on the TS networks. Loss of both TS ECGS cluster nodes (major TS network storage failures) within a site requires manual relocation of the ECGS service to the alternate site to support National Gateway customers who subscribe to alternate site message routing and/or connect to both sites using point-to-point circuits or dial-in Secure Terminal Equipment (STE) secure modem connections. ECGS systems are connected to the DoD NIPRNET, SIPRNET and OM TS/C.

Essential Responsibilities:

  • Administer the ECGS/Mailroom Profile libraries and Message Center folders to include creation and maintenance of custom profiles to support advanced message filtering requirements on both large and small ECGSs.
  • Monitor both the National Gateway Large ECGS and all small ECGSs supporting OM and email interfaces to ensure that messages are being processed.
  • Identify, analyze, and resolve problems of all configured ECGS serial circuit communication ports, message routing database tables, Plain Language Address (PLA) databases tables, application specific configuration database tables, and all Mailroom Profiler selection, restriction, and dissemination profiles.
  • Monitor local and remote distributed applications, host Windows Operating Systems, network connections, and Protogate serial-network communication [i.e. Automatic Digital Network (AUTODIN) Mode-I, Mode-II protocols] subcomponents including the use of protocol analyzers and oscilloscopes to ensure the continued successful processing of messages between each ECGS and all connected remote stations.
  • Continuously staff the National Gateway service operator positions (Service Desk and Mailroom) to correct intercepted messages, send or respond to operational service wires, and manually associate sectional messages.
  • Support provisioning and testing of new point-to-point and dial-in STE connections to the ECGS systems.
  • Provide support to the DISA functional teams for accreditation testing of ECGS hardware and/or application updates.
  • Perform cryptographic Key Management Center updates to STE secure modem Crypto Ignition Keys.
  • Provide, within the monthly IPR and in support of monthly metric collection, reports detailing message volume by port.
  • Monitor all service queues, manually processing all intercepted messages and coordinate with connected sites. For reporting purposes, provide a report on the number of intercepted messages manually processed daily.
