Job description

About Us

We're a multicultural team of experts pushing the boundaries of what's possible in integrated optics. Our mission is to make photonic integration accessible and industrially scalable. We deliver best-in-class PIC platforms, design enablement, and integrated solutions that empower our customers to innovate faster and bring light-based technologies from concept to production.

About The Role

The Process Integration Engineer will lead the transfer, qualification and optimisation of silicon photonics and heterogeneous integration processes from development into production. Working closely with cross-functional teams including process engineering, device design, equipment maintenance, quality and third-party foundry partners, the role is accountable for establishing 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, identify deviations early, and drive rapid root-cause analysis with internal teams and fab partners.
• Lead continuous improvement initiatives across photonic performances, 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.

What You Bring

• Advanced degree in photonics, microelectronics, or a related field.
• Minimum 3 to 5 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
• Goal oriented and driven to work on the next generation photonic technologies
• Proficiency in English; fluency in French is a strong plus

Desirable

• Experience in heterogeneous integration, wafer bonding and hybrid integration of III-V or other materials onto silicon platforms.
• Hands-on history with automation for high-volume manufacturing and familiarity with industry standard data analysis tools.
• Prior exposure to supply-chain and capacity planning for foundry partnerships.

What We Offer

A dynamic role at the heart of the deep-tech revolution where your technical expertise directly impacts product adoption. You will join an international team of specialists, gain deep exposure to market-leading photonic applications, and shape how photonic integration is deployed worldwide.

Practicalities

• Location: Corbeil-Essonnes, France.
• Work percentage: 100%.
• Languages: English is our working language, other languages are a plus.
• Home office: up to two days per week.
