Administer large-scale Linux HPC clusters, automate operations with Bash and Python, install and support software, integrate storage, virtualization, and container technologies, and maintain security compliance. The engineer will collaborate across hardware, networking, storage, systems, and customer teams while documenting technical solutions and supporting long-term infrastructure sustainment.

Develop, enhance, and maintain information management software and infrastructure services for high-performance computing systems in Linux environments. Apply Python to solve engineering challenges, work with PostgreSQL and SQL, and support automated deployments using Ansible, CI/CD pipelines, and containerization technologies. Collaborate with modern development and infrastructure tools, with familiarity in Agile methodologies, DCIM platforms, and documentation systems.

Deploy and maintain secure, reliable software across high-performance computing environments. Build infrastructure automation with Ansible and Python, deploy containerized services using Kubernetes and Helm, maintain GitOps deployment pipelines, and lead Tier 3 escalations. Investigate infrastructure issues, identify root causes, develop automated remediation, and produce comprehensive technical documentation including runbooks, installation guides, and architectural diagrams.

Build and automate production HPC infrastructure using Infrastructure as Code, Ansible, Python, containers, Kubernetes, and GitOps practices. Prepare releases, maintain and troubleshoot pipelines, create Helm charts, and support secure deployments. Serve as a Tier 3 escalation lead, partnering with Operations and Maintenance teams to resolve complex infrastructure issues, identify root causes, and develop automated fixes. Produce technical documentation, runbooks, installation guides, and architectural diagrams.

Develop, maintain, test, and integrate Java-based applications using Spring frameworks. Work with Linux, containerization (Docker/containerd), Kubernetes orchestration, NoSQL (MongoDB), messaging (RabbitMQ/Kafka), CI/CD (Bamboo/GitLab CI), and IaC (Ansible). Troubleshoot, automate, and collaborate across COTS and open-source components.

Perform TEMPEST/EMSEC testing and signal analysis on cryptographic and COTS equipment, record and report results, identify and mitigate emanation vulnerabilities, work with vendors and project teams to verify test requirements (CTTA/NSITSSAM), and validate IASRD application while supporting onsite customer mission needs.

Design, develop, and sustain integrations, plugins, scripts, and automation for Atlassian-based collaboration (Jira, Confluence) in Linux. Collaborate with developers, admins, and customers to streamline workflows, automate tasks, deploy containerized services with CI/CD, and document configurations and procedures.
