• Facilitate integration discussions with engineers and stakeholders by producing architecture views that remove ambiguity (system boundaries, data exchanges, behaviors, constraints).
• Mentor engineers on model quality, modeling discipline, and stakeholder-focused view creation; support governance and publishing standards.
• Produce briefings and architecture products suitable for program reviews and working groups.

• Must have a have a master's degree in a technical or scientific field from an accredited college or university or a bachelor's degree in a technical or scientific field from an accredited college or university and an additional four (4) years of recent and relevant experience.
• 10+ years MBSE and/or systems architecture experience on complex DoD mission systems
• Demonstrated SysML modeling leadership (tool-agnostic, but must be hands-on and review-ready)
• Strong interface/integration engineering instincts (ICDs, data flows, behaviors, dependencies)
• Proven ability to translate stakeholder intent into model structure and engineering direction
• Selected candidate must pass a background investigation
• Demonstrated willingness and ability to operate effectively in environments with strong opinions and tough personalities, staying professional, calm, and outcome-focused while driving technical closure and maintaining model integrity.
• Active Top Secret required; TS/SCI eligibility a plus.
• Must be a US Citizen
• Experience producing decision-quality architecture views and model-backed technical arguments for leadership
• Experience with airborne C2, tactical data exchange, mission system integration, or sensor/comm-centric architectures
