About The Position

The ISR (Intelligence, Surveillance & Reconnaissance), Aviation, and Security (IAS) business area is a leader in ISR and aviation, specializing in manned and unmanned aircraft systems integration for innovative, high-performance ISR and aviation systems. It provides end-to-end Command, Control, Computers, Communications and Intelligence, Surveillance & Reconnaissance (C4ISR) capabilities, encompassing design, integration, test, certification, ground/flight training, and complete logistics support. Sierra Nevada Corporation (SNC) is leading the U.S. Air Force’s (USAF) Survivable Airborne Operations Center (SAOC) mission to modernize and deliver the next-generation SAOC aircraft. As a Principal Electrical Engineer, you will serve as a strategic leader and technical authority in the design, development, and validation of electrical/electronic systems for advanced aerospace and defense projects, providing direction, mentorship, and innovative solutions. In the role of Electrical CATIA Aircraft Integrator, you will lead the design and development of aircraft-level geometry and electrical system integration activities. This position requires deep expertise in CATIA V5+ and 3DEXPERIENCE environments to ensure seamless integration of electrical and mechanical subsystems into a cohesive, manufacturable aircraft configuration. You will act as a technical leader, guiding design teams, maintaining master geometry, defining interface control, and enforcing best practices in relational and model-based design (MBD), with a specific focus on CATIA Electrical and the logical and physical product structure.
