Senior Process Integration Engineer

About the job

• Responsibilities

• Drive new product and new process development to ensure timely and successful delivery of qualified products.

• Oversee day-to-day progress of matrix lots to keep development activities on track.

• Manage part numbers and BOM to ensure proper setup for new product introduction.

• Support the NPI team in establishing mask sets, process flows, and workflows for both front-end (wafer fabrication) and back-end (die assembly and characterization) processes.

• Assist in failure analysis by investigating issues found during wafer fabrication and product characterization and take the lead in analyzing root causes.

• Coordinate production ramp-up readiness by working closely with cross-functional teams—including EPI, process, assembly, test, and product engineering—to ensure readiness in areas such as chip design/specs, equipment, process documentation, and data infrastructure.

• Collaborate with the product engineering team to improve yield, especially in addressing characterization issues that span multiple process areas.

• Design and execute experiments related to design, process, and testing to identify and implement corrective actions for failure modes encountered during new product development.

• Experience

• 3 years of experience in III-V semiconductor laser related device design, process

development and characterization is required.

• PhD degree in electrical engineering, material science, physics, or other relevant

major.

• Skills & requirements

• Hands-on experience with design, process and characterization of optoelectronic device such as VCSEL, DFB laser, or photonic integrated chip.

• Strong statistical data analysis skills (JMP or Minitab etc.).

• Familiarity with semiconductor wafer fab operations (Manufacturing Execution System, process and quality control, change management etc.).

• Experience with optoelectronic device reliability testing and modeling is a plus.

• Strong communication skills; adept at hosting effective meetings and facilitating actions and resolving conflicts.

• Strong ability to drive actions and solutions through cross-functional teams.

• Collaborate in a professional and respectful manner with coworkers, vendors, contractors, etc.
