• Manage container orchestration platforms and deployment tooling.
• Improve system observability through logging, monitoring, tracing, and alerting.
• Support infrastructure and platform operations within high-security environments.
• Work with engineering teams to improve reliability, deployment velocity, and operational resilience and support security hardening, vulnerability remediation, patching, and compliance requirements.
• Troubleshoot infrastructure and deployment issues across development, staging, production, and customer-representative environments.
• Participate in technical planning, platform evolution, and operational readiness activities and document infrastructure standards, operational procedures, disaster recovery processes, and security controls.
• Ability to obtain and maintain security clearance.
