Process Integration Engineer - Silicon Photonics

About the role

Ligentec is a team of experts in integrated optics, delivering photonic integration platforms, design enablement and integrated solutions. The Process Integration Engineer leads the transfer, qualification and optimisation of silicon photonics and heterogeneous integration processes from development into production. The role works closely with process engineering, device design, equipment maintenance, quality and third-party foundry partners to build robust, repeatable process flows that meet product specifications, yield targets and manufacturing timelines.

Key responsibilities

• Coordinate the development and qualification of new photonic technologies manufactured in external fabs.
• Monitor process performance, spot deviations early and drive rapid root-cause analysis with internal teams and fab partners.
• Lead continuous improvement across photonic performance, quality, yield, cycle time and cost, turning performance drifts into actionable plans.
• Establish correlations between process parameters to support SPC and technology scaling.
• Prepare technical specifications, track deviations and resolve issues with fab counterparts.
• Work with design, test and process teams to ensure smooth technology transfer from development to production.

Required profile

• Advanced degree in photonics, microelectronics or a related field.
• Minimum 3 to 5 years of experience in PIC development, semiconductor processing or integrated optics; integrated optics experience is a strong plus.
• English proficiency; fluency in French is a strong plus.
• Desirable: experience in heterogeneous integration, wafer bonding and hybrid integration of III-V or other materials on silicon, hands-on automation for high-volume manufacturing, and supply-chain and capacity planning for foundry partnerships.

Required skills

• Good computer skills, with Python, JMP, R or equivalent and data analysis tools.
• Analytical and synthesis skills, strong leadership and autonomy, and good cross-functional teamwork.

What we offer

• Location: Corbeil-Essonnes, France, with 100% work share and up to two days per week home office.
• Start date as soon as possible.
• A dynamic role within an international team of specialists in photonic integration.
