Responsibilities

Develop and optimize processes for precision machining (e.g., CNC milling, turning, tapping) of complex metal parts such as chambers, showerheads, and manifolds.
Evaluate machining risks for critical components and define appropriate tolerances, and process flow.
Identify and manage surface treatment requirements, including chemical cleaning, anodizing, electropolishing, passivation, and plating.
Define and validate process controls to ensure dimensional accuracy, surface quality (Ra/Rz), and contamination control standards (e.g., particle level, ionic contamination).
Lead root cause analysis for process failures and implement corrective actions using engineering tools (e.g., 5-Why, Fishbone, DOE).
Collaborate with quality, planning, and supplier teams to manage internal and outsourced processes.
Support new product introduction (NPI) by coordinating process development, tooling, fixture design, and pilot build.
Maintain clear and up-to-date documentation such as SOPs, process specifications, and control plans.
Additional duties as defined by manager
