Coordinate technology development projects, ensure disciplined execution, and maintain tight control of lot tracking, deviations, and quality events.

Role and Responsibilities

• Coordinate the development and qualification of new photonic technologies manufactured in external fabs.


• Monitor process performance, identify deviations early, and drive rapid root-cause analysis with internal teams and fab partners


• Lead continuous improvement initiatives across quality, yield, cycle-time, and cost.


• Analyse performance drifts and translate findings into actionable improvement plans


• Establish correlations between process parameters to support SPC and technology scaling


• Prepare clear technical specifications, track deviations, and ensure timely issue resolution with fab counterparts


• Work closely with design, test, and process teams to secure smooth technology transfer from development to production

Requirements

• Advanced degree in photonics, microelectronics, or a related field


• Minimum 5-7 years of experience in PIC development, semiconductor processing, or integrated optics


• Experience in integrated optics is a strong plus


• Excellent analytical and synthesis skills


• Strong leadership and autonomy


• Good ability to work with cross-functional teams


• Be able to adapt your communication to situations (internal and external communication)


• Good computer skills are required (Python, JMP, R or equivalent) and knowledge of data analysis systems
