# Sr. Engineer, Process Development

Location: Rowland, CA (Onsite) Position Summary The Process Engineer is responsible for developing, optimizing, and sustaining wafer fabrication processes that support yield, quality, and throughput for InP photonic device lines, specifically InP Buried Heterostructure (BH) DFB lasers and BH Gain Chips (GC). The Process Engineer owns one or more fab process modules (photolithography, PECVD, dry etch, wet etch, and metallization), including the Mesa etch and surface preparation steps that support MOCVD epitaxial regrowth of InP current-blocking layers used to form the buried heterostructure. This role applies advanced technical training in materials, semiconductor processing, and statistical methods to resolve process excursions, improve device performance and yield, and transition new processes into volume production. Working in a III-V cleanroom environment with minimal supervision, the Process Engineer partners closely with Wafer Fab Supervisors, Technicians, Equipment Engineering, Device and Test Engineering, and Quality to maintain Process-of-Record (POR) discipline, drive data-based decisions, and support reliable, high-yield, high-volume manufacturing.
