Responsibilities

Develop and manage the electrical logical product structure, ensuring alignment between functional intent and physical architecture within CATIA/3DX

Translate logical system designs into physical 3D representations, maintaining traceability between electrical schematics, functional definitions, and routed geometry

Collaborate with systems engineering teams to ensure CAMEO-based model data (ie: SysML or MBSE architectures) is accurately mapped into the electrical logical domain

Serve as a bridge between CAMEO models, logical schematics, and CATIA physical installations, ensuring all design data remains synchronized through design changes and revisions

Identify and resolve logical-to-physical (L2P) mismatches, including wire routing conflicts, connector allocation, harness flattening issues, and interface discrepancies

Define and maintain logical-to-physical (L2P) linkage strategies to ensure digital continuity across the MBE ecosystem

Lead integration reviews focused on electrical-specific challenges, such as grounding, EMI/EMC considerations, and harness segregation between systems

Contribute to the development of process standards and data governance for electrical logical and physical model integration

Lead aircraft-level 3D design and integration using CATIA V5+, with focus on Electrical Physical Harness Routing and Harness Manufacturing Assemblies

Develop and maintain 3D master geometry, datums, interfaces, and product structures

Drive consistency in model trees, configurations, and relational design workflows

Collaborate across electrical, mechanical, and systems teams to ensure integration feasibility and compliance

Partner closely with the Mechanical CATIA Aircraft Integrator to align system geometry and interface management

Provide mentorship and technical direction to design teams and CATIA users

Champion Model-Based Engineering (MBE) and Model-Based Definition (MBD) methodologies

Stay current on emerging CAD technologies, aerospace integration trends, and process improvement initiatives

Lead training and establish standards for interacting with aircraft-level design data

Manage subsystem and component interfaces to ensure proper fit, function, and alignment

Maintain relational links, publications, and lifecycle relationships within CATIA/3DX

Support cross-functional integration reviews and digital mockups
