We are looking for a full-time Senior Network Engineer to support the High-End Computer Networking (HECN) task under NASA's Space and Earth Science Data Analysis (SESDA) contract. The HECN team operates high-performance networking solutions for science at NASA Goddard Space Flight Center (GSFC). The work location will be at NASA GSFC in Greenbelt, MD - both remote and in-person work at the facility is required.
The focus of this position is on Network support (both hardware and software with an emphasis on software) including configuring, troubleshooting, and performance-tuning network equipment, including but not limited to routers, switches, firewalls, etc. Candidates will be expected to support the operational network through maintenance and troubleshooting. In addition, the candidate will participate in designing and building high-end, customized networking and server solutions using cutting-edge technology to meet emerging requirements.
This is an ideal position for an experienced network engineer who is well-organized and reliable to contribute to and be a part of an established team of highly experienced networking engineers to build and operate high-performance solutions for science. Candidates should be willing to take ownership of assigned tasks, meet deadlines, be willing to learn, adapt quickly to changing requirements, and work both independently and as a part of a team. In addition, applicants will interact with customers so good communications skills are essential.

- Develop and maintain scripts (shell, perl, python, ruby, etc) for monitoring the network using SNMP, sFlow, NetFlow, and the ARP, routing (IPv4 and IPv6), and MAC address tables maintained by the network switches and routers
- Work with collaborating enterprises on performing network R&D that will be beneficial to the evolution of the network and its customer base
- Implement and enforce mandated NASA/Federal network and system security requirements, while minimizing the impact to the user community to the extent possible
- Installing, configuring, and maintaining network equipment such as routers, switches, and firewalls
- Provide quality and timely network user support (end system to end system)
- Deploying critical patches and upgrades to network operating systems of switches and routers to ensure compliance with Information Technology (IT) security requirements
