• Lead systems hardening, secure configurations, STIG implementation, and cybersecurity compliance activities.
• Collaborate across cross-functional product teams (systems, software, security, cloud, DevOps, research) to align engineering decisions with mission and product goals.
• Develop automation and CI/CD workflows—including airgapped pipelines—for deployment, testing, and configuration management.
• Conduct advanced troubleshooting across hybrid infrastructures, distributed services, and mission-critical operational environments.
• Continuously evaluate new technologies, frameworks, and methods, demonstrating continuous learning and adaptability to evolving mission needs.
• Ensure project transition success by delivering strong documentation, knowledge transfer, and sustainment handoff to receiving teams.
• Provide occasional after-hours support to sustain critical operations.
• Other duties as assigned.
