Lead the full project to design, install, qualify, and scale in-house pre-penetrant etch capability supporting FPI, including process selection, equipment layout, and material-specific etch recipes (acids/alkalis tailored to alloys such as stainless steels, titanium, aluminum, nickel-based alloys, etc.). The position focuses on standing up safe, controlled, and scalable chemical etch operations that remove a precisely controlled layer of smeared metal (typically 0.00005–0.0002 in) from machined surfaces so that subsequent FPI can reliably detect surface-breaking defects.
