Job Description

MTSI is seeking a highly skilled Senior Enclave Administrator to provide expert‑level leadership and technical oversight within our customer’s Software Branch, supporting classified programs and mission‑critical development activities. In this role, you will manage the operation, security, configuration, and sustainment of multiple secure enclaves that host software development, integration, and test environments across high‑visibility programs. The successful candidate will serve as the authoritative lead for enclave administration, ensuring compliant, reliable, and well‑controlled computing environments that support source‑code development, data storage, digital engineering workflows, mission applications, and specialized software tools. Responsibilities include establishing and maintaining enclave configurations, enforcing security controls, implementing system updates, managing user access, ensuring compliance with applicable security and classification requirements, and providing direct support to the program office across all enclave operations and sustainment activities.

Key Responsibilities

• Lead the overall configuration, security, maintenance, and lifecycle management of multiple classified and unclassified enclaves supporting software development and mission‑system activities.
• Design, deploy, and maintain enclave services, virtualized environments, compute nodes, storage systems, and development toolsets to meet program needs.
• Establish and enforce enclave policies, access controls, user‑account structures, authentication mechanisms, and privileged‑access procedures.
• Manage system updates, patches, STIG implementations, vulnerability remediation, and configuration baselines across enclave components.
• Ensure enclave environments meet all DoD, component‑level, and program‑specific cybersecurity, classification, and auditing requirements.
• Oversee enclave documentation, including system configurations, change records, SOPs, maintenance logs, security evidence, and operational procedures.
• Monitor enclave performance, availability, and security posture; proactively identify issues and implement corrective actions to ensure system reliability.
• Coordinate with system owners, developers, cybersecurity personnel (ISSM/ISSO), and network teams to support mission‑focused development and operational activities.
• Provide onboarding and training for users on enclave workflows, security procedures, tool usage, and data‑handling requirements.
• Conduct enclave readiness assessments, improvement plans, and technical recommendations for leadership and stakeholders.
• Stay current on emerging enclave technologies, secure‑system administration practices, virtualization tools, and classified‑environment requirements to continuously enhance branch capabilities.

Position Requirements

• Deep technical understanding of secure systems administration (Windows/Linux), enclave operations, virtualization, and software‑development support environments.
• Experience managing classified or highly regulated IT systems.
• Strong knowledge of DoD cybersecurity requirements, STIGs, RMF compliance processes, and vulnerability‑management procedures.
• Ability to work independently in secure environments and translate complex technical or mission requirements into practical, compliant enclave configurations.
• Strong communication skills and the ability to support multi‑disciplinary teams across a software‑centric organization.

The successful candidate will serve as the authoritative lead for enclave operations, ensuring secure, reliable, and well‑controlled computing environments that support software development, integration, and mission‑focused activities. Responsibilities include configuring and maintaining enclave systems and services, managing user access and permissions, enforcing security and classification controls, implementing system updates and patches, and providing direct technical support to the program office across all enclave administration and sustainment activities.
