About The Position
Join GDIT as a Systems Administrator and build an impactful career in enterprise IT, collaborating with people who are driven and resourceful.

Familiarity with security hardening concepts, reporting/remediation, and experience writing POAMs is expected. You will deploy approved release packages and break-fix solutions in accordance with enterprise architecture and configuration, change, and release management policies. You will monitor infrastructure, systems operations, and critical application services 24/7, provide information on system limits, and respond to critical outages. Experience developing and interpreting detailed installation instructions and supporting documentation is required. You will provide technical expertise in system design, installation, configuration, tuning, capacity planning, troubleshooting, and problem resolution. You will participate in the validation matrix role to test and validate solutions. You will set up administrator and service accounts, maintain system documentation, tune system performance, and install system-wide software. The ability to perform work under continuous deadline pressure is necessary.
