• Automate infrastructure deployment, configuration management, and operational workflows using tools such as Terraform and Ansible.
• Support Kubernetes- and container-based environments used for AI applications and model serving.
• Work closely with cybersecurity teams to implement hardening, access controls, monitoring, and other security requirements for AI systems.
• Participate in threat modeling, risk assessments, and ATO-related activities for AI infrastructure and integrations.
• Monitor and troubleshoot issues across systems, networks, applications, and cloud environments.
• Develop operational documentation including architecture diagrams, runbooks, SOPs, and integration documentation.
• Advise technical leadership and mission stakeholders on implementation approaches, tradeoffs, and operational risks related to AI technologies.
• Mentor junior engineers and contribute to improving engineering and operational practices across the team.
