• Collaborate with hardware and subsystem suppliers to evaluate and optimize process-critical components such as showerheads, gas delivery, and pressure control

• Develop new plasma process regimes and chemistry strategies to enhance reactor capabilities for advanced technology nodes

• Design and execute process experiments (DOE) to identify and mitigate defectivity, wafer damage, and plasma instability

• Select materials and precursors to evaluate new gas chemistry combinations and ensure material compatibility for advanced film applications

• Apply process metrology and diagnostic techniques (e.g., OES, mass spectrometry) to characterize plasma properties and integrate end-point control

• Collaborate closely with cross-functional teams and implement process improvement initiatives

About you

• Masters or PhD in Chemical Engineering, Material Science, or a closely related field with at least 5 years of relevant industry or academic experience

• Strong oral and written communication skills to clearly present complex technical ideas

• Structured problem-solving methodologies such as Root Cause Analysis, Six Sigma, Fishbone Diagram, and 5 Whys

• Familiarity with semiconductor process and characterization tools such as SEM, film thickness and stress measurement, plasma diagnostic tools, and OES

• Knowledge of material properties, thin film characterization, and plasma chemistry dynamics

• Hands-on experience with wafer handling, chamber maintenance, manual tool operation, and basic mechanical/gas-line assembly
