About The Position

The Senior Core Infrastructure Engineer will help deliver reliable platforms that enable controlled information sharing between networks operating at different security levels. The role calls for broad systems infrastructure experience, security-first engineering, and the ability to troubleshoot complex interactions across compute, storage, networking, virtualization, identity, and cross-domain components. The engineer works in highly controlled environments, translates security requirements into practical designs, and collaborates with security, network, application, accreditation, and operations teams. The position designs, deploys, configures, and maintains infrastructure that hosts or integrates with Cross Domain Solutions (CDS), including data diodes, guards, transfer and access solutions, and protocol or content-filtering services. It creates technical designs, implementation plans, configuration standards, system diagrams, test procedures, and operational documentation. The role also builds fault-tolerant systems, defines scalability requirements and performance indicators, and develops monitoring, telemetry, dashboards, alerting, replication, and synchronization capabilities. The engineer supports security assessment and authorization, system hardening, vulnerability remediation, patching, and lifecycle management. Operational duties include platform monitoring, complex troubleshooting, incident response, root-cause analysis, change and problem management, and operational support rotations. The role automates provisioning, configuration, compliance validation, and routine operations; develops scripts and Infrastructure as Code for cloud infrastructure; and plans upgrades, migrations, capacity improvements, and technology refreshes with minimal disruption. The position also coordinates moderately complex tasks and project deliverables, collaborates across teams and with stakeholders, provides technical guidance, contributes to engineering standards and reusable solutions, and supports continuous learning and improvement. Oracle describes a comprehensive benefits package and states that the role may be eligible for bonus and equity.

Responsibilities

Design, deploy, configure, and maintain infrastructure that hosts or integrates with Cross Domain Solutions.
Integrate CDS technologies, including data diodes, guards, transfer solutions, access solutions, and protocol or content-filtering services.
Develop technical designs, implementation plans, configuration standards, system diagrams, test procedures, and operational documentation.
Design fault-tolerant systems that support in-service updates through redundancy, replication, and automatic failover.
Define scalability requirements for owned components and ensure design and implementation requirements are met.
Define KPIs and telemetry, and build dashboards, monitoring, and alerting mechanisms for system health.
Implement data replication and synchronization techniques to maintain data integrity and availability.
Support security assessment and authorization by implementing controls, producing technical evidence, and resolving findings.
Apply system hardening guidance, configuration baselines, vulnerability remediation, patching, and lifecycle-management practices.
Troubleshoot complex issues across infrastructure, applications, networks, security controls, and CDS components.
Monitor platform health, performance, capacity, and availability, and identify risks before they affect mission services.
Participate in incident response, root-cause analysis, change management, and problem-management activities.
Participate in operational support rotations and provide guidance during incident response and root-cause investigations.
Automate provisioning, configuration, compliance validation, and routine operational tasks where appropriate.
Develop and maintain automation scripts and tools, including Infrastructure as Code, to manage cloud infrastructure.
Create and follow change-management plans for patching, updating, and rolling back applications, and design systems and components to support automation of these processes.
Plan and execute upgrades, migrations, capacity improvements, and technology refreshes with minimal operational disruption.
Coordinate moderately complex tasks, timelines, deliverables, and work across projects or initiatives; provide technical oversight and adjust plans as needed.
Collaborate with cybersecurity, network engineering, enterprise architecture, application teams, vendors, mission stakeholders, and other organizational partners.
Provide technical guidance to engineers and contribute to engineering standards and reusable solutions.
Analyze moderately complex issues, document problem-solving strategies, escalate critical or unresolved issues, and suggest potential solutions.
Pursue learning and feedback, stay current with industry trends and best practices, and coach and mentor junior team members.
Recommend and help implement improvements to processes, protocols, and workflows, incorporating feedback on alternative approaches.
