• Oversee the integration of PHE with the PSS Local Infrastructure (PLI), ensuring seamless network connectivity and performance to all hosted PSS Products.
• Develop and implement the DevSecOps strategy for VHE, automating infrastructure provisioning, configuration management, application deployments, and security testing.
• Support the development and maintenance of CI/CD pipelines, integrating security tools into the pipeline and adhering to agile principles.
• Oversee the selection and implementation of appropriate technologies for the VHE platform, including virtualization, networking, storage, and security while considering the established architectural runway.
• Ensure compliance with DoW and Navy security standards (STIGs, RMF, CNSSI 1253).
• Collaborate with other teams, including security, network, and application development, to ensure the successful operation of the VHE platform.
• Support the adoption of agile practices within the VHE development teams, ensuring alignment with the overall agile implementation roadmap.
• Lead the deployment and management of elasticsearch enterprise clusters and its ecosystem, ensuring scalability, performance, and security.
• Design and implement Infrastructure as Code (IaC) solutions for deploying IT service infrastructure, including networking, storage, and compute resources
• Plan, develop, and execute migration strategies to enterprise platforms in alignment with portfolio management.
• Experience in architecting and designing cloud infrastructure enclaves to support hybrid cloud models with IaaS, PaaS, and SaaS solutions.
• Support corporate business development initiatives as needed.
