@charlesokonski

I design, verify, and test mission-critical aerospace and defense systems.

United States
Message

At L3Harris Technologies, I design EO/IR sensor and imaging systems for submarines, surface ships, combat vehicles, and other defense platforms. I flow down and decompose requirements, verify and validate systems, and write test methods, procedures, and reports.

Across Boeing, Raytheon, Parker Aerospace, Collins Aerospace, Panasonic Avionics, and Northrop Grumman, I've delivered systems engineering, reliability analysis, integration, and testing for aircraft, satellite sensors, flight controls, space systems, and avionics. I bring hands-on experience with DOORS, requirements traceability, DFMEA, fault tree analysis, environmental testing, and regulated quality systems.
