About The Position

Oracle Health’s Core Platform Operations team supports the core platforms that run Millennium, including Linux infrastructure, Application Tier, WebSphere, Distributed File Systems, Business Objects, and Citrix. The team works to keep these platforms reliable, secure, and maintainable for healthcare organizations. Its work connects Linux engineering with the behavior of services running above it, using approaches such as rolling maintenance, canary environments, and maintenance orchestration to reduce manual effort and human error.

The Principal Site Reliability Engineer manages, maintains, and enhances physical and virtual Linux servers across production and nonproduction environments. The role applies technical judgment to system configuration, performance tuning, security patching, capacity planning, and complex troubleshooting, and helps shape team standards and tools. It is a hands-on individual contributor position with technical leadership responsibilities, including guiding engineering decisions, mentoring colleagues, participating in on-call support, and serving as an escalation resource for assigned services. The engineer collaborates with application, networking, security, and infrastructure partners to resolve operational problems and improve engineering practices.

Responsibilities

• Configure, update, maintain, and troubleshoot physical and virtual Linux servers across production and nonproduction environments, focusing on availability, performance, stability, and security.
• Evaluate infrastructure configurations and service dependencies, identify failure points, and recommend improvements to reliability, scalability, and maintainability.
• Analyze CPU, memory, storage, filesystem, process, and network behavior; forecast resource needs, investigate bottlenecks, and tune systems using measured results.
• Improve metrics, logging, health checks, and actionable alerts; use service trends and service-level objectives to identify degradation and prioritize engineering work.
• Diagnose complex incidents across operating systems, applications, networking, storage, and related dependencies; coordinate with partner teams to restore service and communicate findings.
• Perform root cause analysis and post-incident reviews, translating findings into corrective actions, improved diagnostics, runbooks, and engineering improvements.
• Apply security patches and updates, remediate vulnerabilities, strengthen configurations and access controls, and maintain compliance with applicable security standards and policies.
• Plan production maintenance and changes, assess dependencies and risk, prepare rollback procedures, and validate system and application behavior after changes.
• Develop, test, document, and maintain Bash, Python, Ansible, or comparable automation for configuration, maintenance, monitoring, and recovery; use version control and peer review.
• Partner with developers, network engineers, security teams, and other IT staff on deployments, environment readiness, connectivity, and server-related requirements.
• Help validate backup, restore, and recovery procedures for assigned systems and address gaps that could delay service restoration.
• Maintain architecture diagrams, standard operating procedures, troubleshooting guides, and change records; mentor colleagues, share knowledge, and communicate technical risks and recommendations to stakeholders.
• Participate in on-call rotations and planned maintenance, provide escalation support for assigned services, and improve support documentation and tooling.
