Develop implementation plans, test plans, diagrams, operating procedures, and other technical documentation.
Troubleshoot complex interoperability and performance issues across multi-vendor network and security environments.
Assist deployment and sustainment teams with production implementation, transition, and technical escalation.
Collaborate with network, cybersecurity, systems, application, and infrastructure engineering teams.
Identify and communicate relevant security threats, vulnerabilities, and technology risks.
Ensure designs align with applicable security and compliance requirements, including FISMA, DISA STIG, and FIPS requirements where applicable.
Provide technical mentoring, knowledge transfer, and instructional sessions for engineering and operations personnel.
Participate in architecture reviews, project planning, technology evaluations, and engineering team meetings.
Provide concise status updates and project reporting.

This position is designed to be flexible, with responsibilities evolving to meet business needs and enable individual growth.
