Position Summary: As a Journeyman Network Engineer - Airborne Networking Systems, you will lead the digital thread transforming innovative ideas into flight-ready capabilities for Major Release, focusing on requirements, architecture, and model-based systems engineering across hardware, software, and operations domains. Essential Job Functions: rchitect and model the System-of-Systems using government-owned SysML/CAMEO models, DoDAF views, and interface-control documents (ICDs) capturing interactions among hardware, software, and operations with the Digital Infrastructure, SATCOM links, and cross-domain solutions. Ensure every requirement traces to a verification method and mission thread aligned with CJADC2 and Operational Imperative #2 objectives. Elicit, decompose, and manage stakeholder needs using DOORS-NG or equivalent; lead requirements reviews, delta boards, and configuration-control boards. Maintain the Technical Baseline and manage change packages through digital workflows, preserving synchronization between models and documents. Partner with IPT leads to translate digital designs into Integration SIL builds and resolve technical interface issues related to cross-domain, crypto, power, and data-bus interfaces efficiently. Integrate lessons learned back into models to ensure accurate baselines for subsequent sprints. Collaborate with Test and Flight-Test teams to develop the Verification Cross-Reference Matrix (VCRM) and apply early "shift-left" validation for safety, cyber security, and performance requirements. Provide pre-flight technical concurrence for Interim Authorizations To Test (IATTs) and air-worthiness packages. Maintain the technical risk register, conduct root-cause analyses, and communicate burn-down plans to senior leadership. Contribute schedule, maturity, and performance metrics to the Integrated Master Schedule (IMS) and digital dashboards. Mentor mid-level engineers on MBSE best practices, Agile/SAFe workflows, and DevSecOps culture within a classified environment. Foster a collaborative, "model-first" culture among government and industry team members. Required Skills and Qualifications: Bachelor's degree in Systems, Electrical, Aerospace, Computer Engineering, or a related field, with 15+ years of systems engineering experience on DoD C4ISR, avionics, or open-architecture programs; or a Master's degree with at least 12 years of experience. ctive TS/SCI security clearance. Proficient with SysML modeling tools such as CAMEO/MagicDraw, Rhapsody, or equivalents, and requirements management tools like DOORS and Jama. Demonstrated leadership in multi-disciplinary design reviews (SRR, PDR, CDR) and managing technical baselines in a digital-engineering environment. Strong understanding of MIL-STD avionics power, data links (Link-16/22, TTNT, OMS/UCI), SATCOM systems, Type-1 cryptography, and RMF/IA compliance. Desired Skills: INCOSE CSEP/ESEP or DAU ENG/SAE Level III certification. Prior experience with ABMS, CJADC2, or other open-architecture airborne networking initiatives. Familiarity with DevSecOps pipelines (Platform One/Iron Bank) and automated model validation tools (ModelCenter, Cameo Simulation Toolkit). Experience briefing senior executive service (SES) or general officer (GO) audiences and supporting acquisition strategy development (AS, SEP, SEMP, TEMP).
