Wafer processing Engineer

Wafer Process Engineer (III-V Semiconductors / Laser Diodes)

Paris Area, France (Relocation Support Available)

International Travel Required

R&D / Process Engineering

About the Role

We are seeking an experienced Wafer Process Engineer to join our R&D team, focusing on the development and optimization of III‑V semiconductor processes for InP and GaAs‑based laser diodes. This is a hands‑on role at the intersection of process development, manufacturing, and supplier collaboration, with direct impact on device performance, yield, and scalability.

Key Responsibilities

• Develop and optimize wafer fabrication processes for III‑V laser diodes (InP, GaAs)
• Improve process yield, performance, and cost efficiency
• Collaborate with cross‑functional teams (engineering, reliability) to assess process impact on device performance and lifetime
• Support technology transfer from R&D to production
• Work closely with external foundries: evaluate and qualify manufacturing partners; implement and scale processes in outsourced environments; monitor performance and drive continuous improvement; contribute to process documentation and standardization

Your Profile

• 5+ years of experience in III‑V wafer processing
• Strong hands‑on expertise in lithography, wet and dry etching, thin‑film deposition/metalization
• Experience in industrial or high‑volume semiconductor manufacturing
• Familiarity with InP and/or GaAs technologies
• Understanding of laser diodes, photonics, or optoelectronic devices is a strong advantage
• Experience working with or managing external foundries is a plus

Additional Requirements

• Fluent in English (French is a plus)
• Willingness to relocate to the Paris area
• Open to international travel
