Description

SAIC is seeking a highly skilled Cross-Domain Network & Data Systems Engineer to support our work at Naval Surface Warfare Center (NSWC) Crane, Indiana in direct support of the Mach-CORE program.

In this role, you will design, implement, and sustain secure network architectures enabling the controlled transfer of digital engineering data across multiple security classification boundaries. This position directly supports advanced weapons development environments, with a specific emphasis on enabling data exchange between external programs - most notably the Multi-Service Advanced Capability Hypersonic Accelerator (MACH-XL) - and internal analysis systems.

This is a high-visibility, on-site role that places you at the intersection of network engineering, cybersecurity, and cutting-edge hypersonic weapons development - contributing directly to programs that define the future of national defense.

Your Mission at SAIC

Network Architecture & Infrastructure

• Architect, deploy, and maintain secure network infrastructures supporting multi-level security (MLS) and cross-domain data movement
• Design and optimize data transfer pathways for complex datasets, digital engineering models, and analytical outputs between classified and unclassified environments
• Deliver hands-on expertise across routing, switching, firewall management, and secure network architecture design

Cross-Domain Solutions & RMF Compliance

• Implement and manage DoD-accredited cross-domain solutions (CDS), ensuring full compliance with all policy and operational requirements
• Conduct RMF-aligned security engineering activities including documentation, system hardening, control implementation, and continuous monitoring
• Support accreditation activities, technical reviews, and stakeholder engagements across DoD organizations

MACH-XL Integration & Data Pipeline Support

• Lead the integration of MACH-XL data pipelines into internal analysis tools and systems
• Troubleshoot and resolve network security, configuration, and data-flow issues within high-assurance architectures
• Collaborate with SAIC cyber, systems, and mission engineering teams to ensure end-to-end data integrity and security

Qualifications

Required Qualifications

• Bachelor's degree in computer engineering, Network Engineering, Information Systems, Cybersecurity, or a related field and 9 years of equivalent professional experience
• Demonstrated experience designing or supporting DoD or Intelligence Community (IC) networks operating at multiple classification levels
• Working knowledge of cross-domain technologies including radiological filters, data guards, and transfer appliances
• Familiarity with DoD RMF processes, STIGs, and system authorization requirements
• Strong foundation in routing, switching, firewall management, and secure network architecture design
• Ability to work on-site within classified workspaces at NSWC Crane, Indiana

Preferred Qualifications

• Experience integrating data workflows or engineering models for advanced weapons systems or digital engineering programs
• Hands-on experience with MACH-XL, hypersonics, or modeling and simulation data environments
• Active certifications such as Security+, CISSP, CCNA/CCNP, or equivalent
• Experience with automated data pipelines, structured data transfer protocols, and zero-trust architectures

Required Security Clearance

• Interim secret clearance required to start with the ability to obtain a secret clearance. SAIC will sponsor the clearance process.
