• Perform routine maintenance, patching, and lifecycle management of GOTS applications within classified environments

• Coordinate with program stakeholders and developers on GOTS software integration, compatibility testing, and issue resolution

Scripting and Automation

• Create, read, modify, and maintain automation scripts in Bash and Python to support system administration, deployment, and operational tasks

• Automate repetitive operational workflows including system monitoring, configuration enforcement, log analysis, and health checks

• Support team adoption of automation and scripting best practices

Testing and Troubleshooting

• Design and execute system-level test plans, acceptance test procedures, and regression tests

• Lead troubleshooting efforts across complex, multi-component classified systems; document findings and remediation actions

• Participate in operational readiness reviews and system validation activities prior to deployment

Qualifications:

Education: Bachelor’s degree in Computer Science, Systems Engineering, Information Technology, Electrical Engineering, or a related technical field. Equivalent experience (4+ additional years of direct systems engineering experience in lieu of degree) may be considered.

• Proven ability to create, read, and modify automation scripts in Bash and/or Python

• Strong testing and troubleshooting skills across complex, multi-component systems

• Ability to produce technical documentation and drawing packages (system designs, ICDs, test plans, as-builts)

• Comfortable operating within a small, agile, mission-focused team that interfaces regularly with users, customers, and adjacent technical teams

• Strong written and verbal communication skills in a security-controlled environment
