• Develop automation that improves consistency, repeatability, security, and operational efficiency.

• Participate in incident response, problem management, root-cause analysis, and continuous improvement.

• Collaborate with architects, network engineers, cybersecurity professionals, application teams, operators, and mission stakeholders.

• Develop and main automated provisioning, configuration, testing, monitoring, and recovery capabilities that improve system resiliency, redundancy, security, and operational efficiency.

• Verification, validation, test planning, and acceptance criteria.

• Automation, scripting, configuration management, and infrastructure-as-code concepts.

• Performance analysis, capacity planning, and technical risk management.
