Sr Materials Engineer, Wet Processing (Ingot/Wafer)
Core
Set technical standards for wet-process chemistry and materials to convert silicon ingots into production-ready wafers for high-efficiency solar cells.
Role type
Senior IC materials engineer (semiconductor/solar PV wet processing)
Builds
Silicon ingot and wafer production lines for Starlink solar cells
Domain
Semiconductor manufacturing / Solar PV / Chemical engineering
Deliverable
production ML models | product features | dashboards & analysis | research | client delivery | infrastructure | physical/clinical work -> production features (wafer manufacturing process)
Required skills
wet chemical processing, surface chemistry, contamination control, materials characterization, bath chemistry management, supply chain sourcing, hazardous chemical handling, data analysis (Python/JMP/MATLAB), SPC
Preferred skills
silicon wet process ownership (etch/clean/degumming), bath lifetime optimization, minority-carrier lifetime analysis, chemical delivery systems, industrial wastewater constraints, high-volume fab environment experience
Technologies
ICP-MS, TXRF, VPD, FTIR, TOC, SEM-EDS, XPS, optical microscopy, four-point probe, QSSPC/PL lifetime, Python, JMP, MATLAB
Responsibilities
Define chemical requirements, bath recipes, and acceptance criteria; lead cross-functional efforts to source and qualify wet chemicals; execute wet-process qualification programs; serve as primary technical escalation for contamination and surface-quality issues; mentor teams on wet-process problem solving; communicate technical status and risks to leadership
Seniority
Senior, hands-on IC
