About The Position

Altech Solutions is hiring a Systems Administrator to support NASA's Engineering Directorate at Langley Research Center in Hampton, Virginia. This role lives inside engineering and laboratory environments — the systems NASA researchers and engineers actually use to do their work. If you like being the person scientists come to when their compute environment has to work, this is that job. A significant part of the work is getting scientific and open-source software running: pulling source, resolving dependencies, working through configure and build failures, and getting the result deployed and supportable. You will also administer Linux and Windows servers, support Linux, Mac, and Windows workstations, run Apache web services, manage backups and storage, and stay ahead of security patching and risk.

Bachelor's degree and 4 years of relevant experience
Advanced system administration experience with exposure to Linux, Mac, and Windows
Hands-on experience compiling and troubleshooting open-source software from source
Scripting and command-line experience — Bash, Python, Perl, or similar
Experience performing system backups
Understanding of storage systems including SAN and NAS, and concepts such as RAID, NFS, and LUNs
Understanding of basic networking concepts and IT security best practices
Self-directed — proven ability to satisfy customer needs with minimal day-to-day direction
Strong communication, documentation, and customer-relations skills; effective working independently and on a team
U.S. Citizenship with the ability to obtain and maintain a NASA Public Trust clearance
Residence within 50 miles of NASA Langley Research Center, Hampton, VA

Responsibilities

Build and deploy open-source and scientific applications from source — resolving dependency chains, compiler and library conflicts, and configure/make failures, then documenting the build so it can be reproduced.
Administer Linux and Windows servers: installation, configuration, patching, tuning, and ongoing maintenance.
Support end users on Linux, Mac, and Windows workstations in an engineering and research setting.
Configure and support Apache web servers, including virtual hosts, TLS, and access control.
Debug application and system-level problems using tools such as logs, strace, gdb, and performance analysis utilities — and drive them to root cause.
Write and maintain scripts that automate the repetitive parts of the job.
Maintain system backups and ensure data and media recoverability through scheduled backup and archive operations.
Assist with monitoring and management of storage systems, including SAN and NAS.
Manage virtualized infrastructure — VMware ESXi and vCenter.
Apply configuration management practices so systems are consistent, documented, and auditable, and contribute to planning as the environment evolves.
Resolve system security issues including patching, risk analysis, and supporting security plans.
Track and resolve user issues through the ticketing system, and maintain system documentation, SOPs, and configuration records.
