Principal Systems Administrator

BigBear.ai is hiring a Principal Systems Administrator to support GALE (Generic Area Limitation Environment)-a mission-critical capability used by the Department of Defense (DoD) and the Intelligence Community (IC). In this role, you'll keep a complex Linux-based application environment healthy, secure, and ready for operational use-while working shoulder-to-shoulder with users, engineers, and mission partners. At BigBear.ai, you'll join a team of technologists and mission-focused problem solvers building tools that turn massive volumes of structured and unstructured data into actionable intelligence. If you want your work to matter-and you enjoy being the person who makes systems run reliably in high-stakes environments-this role is for you. What you will do: As a Principal Systems Administrator on the GALE support team, you will:

• Operate and sustain GALE in production across customer environments-ensuring availability, performance, and reliability.
• Maintain cybersecurity compliance by patching and hardening multiple Linux servers to meet security standards and program requirements.
• Install, configure, and upgrade GALE and supporting components across customer sites with minimal disruption.
• Troubleshoot and resolve issues-triaging tickets, identifying root cause, and coordinating fixes with the development team.
• Test new GALE builds/releases, document defects, and validate resolutions before fielding.
• Support and train users and administrators, helping mission teams get maximum value from the platform.
• Contribute analytic insight-providing feedback on enhancements, assisting with ad hoc analysis, and improving future capability.
• Stay adaptable and keep learning, picking up new tools/tech as mission needs evolve.
