[Remote] Principal Network Engineer

Note: The job is a remote job and is open to candidates in USA. Rocketdyne is hiring a Principal Network Engineer to own network architecture and standards across its five sites and direct outsourced network delivery partners. The role leads network-layer security implementation, the transition from inherited infrastructure, and network support for CMMC Level 2, ITAR, and DFARS compliance.

Responsibilities

• Own end-to-end network architecture across all five sites — LAN switching, wireless, and WAN/SD-WAN design
• Design and maintain the SD-WAN architecture, including transport diversity, application-aware routing, and local internet breakout strategy to reduce backhaul dependency and improve site-level resiliency
• Define packet shaping and QoS standards to prioritize latency-sensitive traffic (voice, video, real-time engineering/manufacturing systems) across the WAN
• Set enterprise wireless standards (coverage, security, guest/BYOD segmentation) consistent across all sites
• Maintain network architecture documentation, standards, and reference designs so the environment doesn't drift back into ad hoc, inherited configuration
• Design and implement Teams Phone (or equivalent UCaaS), SBC and SIP trunking design, and PSTN connectivity strategy across all sites, ensuring voice traffic is correctly prioritized within the broader QoS design
• Implement and operate the network-layer components of the zero trust architecture — identity-aware network access enforcement and micro-segmentation — to the strategy and standards owned by the Principal Cybersecurity Engineer & Architect
• Design network segmentation to support CMMC Level 2 / ITAR / DFARS boundary and CUI data-flow requirements, working from the control framework and segmentation strategy set by cyber architecture/GRC
• Partner with the Principal Cybersecurity Engineer & Architect as the network-side technical counterpart on zero trust design — translating security strategy into network configuration, routing, and segmentation, and flagging network-layer constraints or trade-offs back into that strategy
• Execute network-layer containment actions (segmentation, isolation) in support of the security incident response plan owned by cybersecurity
• Lead technical design and execution oversight for replacing L3Harris-inherited network infrastructure and circuits with Rocketdyne-owned network infrastructure across all five sites
• Sequence site cutovers to minimize downtime for engineering, manufacturing, and business operations during the TSA exit window
• Validate WAN/SD-WAN, wireless, and segmentation architecture is fully independent of L3Harris infrastructure ahead of TSA expiration
• Direct and manage outsourced network delivery partners performing day-to-day operations, monitoring, break/fix, and moves/adds/changes across all sites
• Own technical acceptance of outsourced partner deliverables — review, test, and approve network designs and configuration changes before they move to production
• Set technical priorities and work assignments for outsourced partner teams, translating the network architecture roadmap into partner-executable scopes of work
• Escalate and manage partner performance issues (quality, schedule, cost) in partnership with vendor management/procurement
• Evaluate outsourced partner statements of work, circuit/carrier proposals, and level-of-effort estimates for technical soundness before commitment

Skills

• 8+ years in network engineering/architecture roles, with demonstrated ownership of enterprise network design (not just operations)
• Deep hands-on expertise across LAN switching, enterprise wireless, and WAN/SD-WAN platforms
• Direct experience designing and implementing SD-WAN architectures, including local internet breakout strategies
• Experience with packet shaping/QoS design for mixed voice, video, and real-time application traffic
• Experience implementing zero trust network access (ZTNA) and micro-segmentation to a security team's architecture and standards
• Working knowledge of CMMC, ITAR, and/or DFARS network segmentation and boundary requirements, and demonstrated ability to partner effectively with cyber/compliance teams
• U.S. Person status required (ITAR data access)
• Demonstrated experience directing and managing outsourced/MSP network delivery partners — assigning work, reviewing deliverables, and holding partners accountable for quality and schedule without formal supervisory authority over them
• Multi-site aerospace, defense, or complex discrete manufacturing network experience
• Experience replacing or migrating off inherited network infrastructure in a carve-out, divestiture, or M&A context
• Vendor-specific certifications (e.g., CCNP/CCIE, or equivalent for the SD-WAN/wireless platforms in use)
• Experience integrating network architecture with a broader zero trust security program alongside a cybersecurity architect
