• Develop and maintain Kubernetes Operators and Custom Resource Definitions (CRDs) to extend and automate cluster functionality.
• Ensure that all software components adhere to relevant security and compliance standards and support secure operation in a defense environment.
• Stay current with industry best practices and emerging trends in software engineering, Linux, Kubernetes, containers, and modern programming languages.
• Collaborate with cross-functional teams, including architects and other engineers, to integrate new capabilities into the overall system.
• Contribute to architectures that support signal processing, digital signal processing (DSP), satellite, and RF-related capabilities when applicable.
• Participate in technical discussions, design reviews, and problem-solving sessions to refine system architecture and implementation approaches.
