MBSE Digital Modeler

• Develop detailed SysML models representing keyboard subsystems, including key matrices, sensors, switches, controllers, interfaces, and ergonomic considerations.
• Build and maintain MBSE artifacts such as block definition diagrams, internal block diagrams, activity diagrams, state machines, and interface models for keyboard functions.
• Model keyboard behavior including input processing, debounce logic, communication protocols, power consumption, and user interaction flows.
• Collaborate with electrical, mechanical, firmware, and humanfactors engineers to incorporate all keyboardrelated requirements and constraints into the system model.
• Ensure traceability between keyboard requirements, architecture elements, and verification activities within the MBSE environment.
• Conduct model-based analysis to evaluate performance, reliability, environmental constraints, and system interactions related to keyboard operation.
• Integrate keyboard subsystem models into larger system architectures and digital engineering pipelines.
• Apply modeling best practices, enforce model quality standards, and support configuration control of all MBSE artifacts.
• Provide mentoring and guidance on MBSE modeling techniques and keyboard subsystem representation.

• US citizenship and a secret level clearance is required
• 7+ years of handson MBSE experience with strong SysML modeling skills.
• Direct experience modeling hardware/software interactions, embedded components, or input peripherals (keyboard, keypads, HMI devices).
• Bachelor's degree in systems engineering, electrical engineering, mechanical engineering, computer engineering, or related technical field.
• Proficiency with MBSE tools such as Cameo Systems Modeler/MagicDraw, Rhapsody, or Enterprise Architect.
• Solid understanding of systems engineering principles, including requirements, architecture, interface design, and verification.
• Experience collaborating across multidisciplinary teams (electrical, mechanical, firmware, UX).
