Principal Core Infrastructure Engineer - CDS

Job Title

The engineer will help deliver reliable platforms that enable controlled information sharing between networks operating at different security levels.

Key Responsibilities

• System Design & Architecture - Scalability, Reliability, and Performance:
• Design, deploy, configure, and maintain the infrastructure that hosts or integrates with Cross Domain Solutions.
• Integrate CDS technologies such as 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.
• Build and design fault-tolerant components and systems capable of withstanding in-service updates by implementing redundancy, replication, and automatic failover mechanisms.
• Define scalability requirements for owned components and ensure design and implementation requirements are met.
• Define key performance indicators (KPIs) and telemetry to identify gaps or issues in running systems.
• Build and customize moderately complex dashboards, telemetry systems, and alerting mechanisms to proactively monitor components and system health.
• Implement data replication and synchronization techniques to maintain data integrity and availability.
• Compliance & Security:
• Support security assessment and authorization activities by implementing controls, producing technical evidence, and resolving findings.
• Apply system hardening guidance, configuration baselines, vulnerability remediation, patching, and lifecycle-management practices.
• Operational Troubleshooting & Incident Management:
• Troubleshoot complex issues across infrastructure, applications, networks, security controls, and CDS components.
• Monitor platform health, performance, capacity, and availability; identify risks before they affect mission services.
• Participate in incident response, root-cause analysis, change management, and problem-management activities.
• Serve in operational support rotations, providing guidance in incident response and root cause investigations.
• Automation & Change Management:
• Automate provisioning, configuration, compliance validation, and routine operational tasks where appropriate.
• Develop and maintain automation scripts and tools (e.g., Infrastructure as Code (IaC)) to manage cloud infrastructure.
• Create and adhere to change management plans for patching, updating, and rolling back applications, and begin designing systems and components to allow for automation of these processes.
• Plan and execute upgrades, migrations, capacity improvements, and technology refreshes with minimal operational disruption.

Core Responsibilities

• Planning & Execution:
• Manage and coordinate moderately complex tasks, monitoring timelines and deliverables to ensure timely completion and adherence to requirements for a moderately-sized project or initiative. Efficiently delegate, monitor, and prioritize work across multiple projects, providing technical oversight and adjusting plans to address shifts in resources or timelines.
• Collaboration & Partnership:
• Collaborate across the organization to align expectations and achieve shared objectives. Leverage understanding of business leaders, stakeholders, and/or customers to ensure proposed solutions meet their needs. Support inclusivity by actively seeking and listening to diverse perspectives, ensuring others feel heard and respected.
• Work closely with cybersecurity, network engineering, enterprise architecture, application teams, vendors, and mission stakeholders.
• Provide technical guidance to other engineers and contribute to engineering standards and reusable solutions.
• Problem Solving:
• Identify and address moderately complex issues by analyzing a wide range of data and/or information to identify solutions in accordance with standard practices. Proactively escalate unresolved or critical issues with a thorough assessment and suggest potential solutions. Review, contribute to, and document problem solving strategies.
• Continuous Learning:
• Pursue learning opportunities to expand knowledge and skills and/or tools in new areas and stay abreast of the latest industry trends and best…
