Senior — hiring level requires 8+ years of semiconductor process development experience; final hiring level (Principal or MTS) depends on candidate experience and technical depth.

Responsibilities

Key responsibilities include process development, problem resolution, and technical leadership across advanced packaging assembly steps.

• Identify, diagnose, and resolve assembly process-related problems using failure analysis and structured problem-solving.
• Coordinate and implement process, equipment, and material evaluation and optimization; implement changes at process steps.
• Validate and scale innovative processes, tools, and materials for new-product introduction.
• Develop, optimize, and characterize wet chemistry processes to meet product requirements.
• Lead yield improvement, cost-reduction, productivity improvement, and risk-management activities.
• Plan and execute process baselines and new process qualifications.
• Support SPC/FDC/RMS/APC and site-to-site portability activities.
• Manage and audit material suppliers to meet quality, cost, and risk objectives.
• Support internal and external audits.
• Conceive and plan projects involving selection of new concepts, equipment automation, and development approaches.

Requirements

Must-have and preferred technical qualifications (degrees summarized in Education Requirements).

Must-have:

• 8+ years semiconductor industry experience as a process development engineer.
• Demonstrated use of failure analysis, FMEA, 8D, and statistical problem-solving (SPC/FDC) to resolve process issues.
• Experience with process transfer, new-product introduction, and process qualification.
• Experience managing supplier quality and participating in supplier audits.
• Proven ability to lead yield and cost-reduction initiatives.

Nice-to-have:

• Hands-on wet chemistry development experience in a cleanroom environment.
• Experience with Advanced Packaging, DRAM, NAND, or other memory products.
• Experience using Python and statistical tools for data collection, organization, and analysis.
• Experience leveraging AI and automation for data analysis and process improvement.
• Familiarity with material properties, characterization techniques, DOE, and model-based problem solving.

Education Requirements

Minimum: MS in Materials Science, Chemical Engineering, Chemistry, Physics, or a related field. Preferred: PhD in Materials Science, Chemical Engineering, or Chemistry.
