We are seeking a highly motivated and technically skilled engineer to lead the bring-up and qualification of a new Indium Phosphide (InP) photonics semiconductor fabrication facility. This role is critical to establishing high-yield, scalable, and reliable photonic device manufacturing processes in a cutting-edge fab environment. The ideal candidate will have experience with InP or compound semiconductor process development, fab tool qualification, and yield improvement. Fab Bring-Up & Equipment Qualification: Support the start-up and drive the qualification of front-end and back-end process tools for InP-based photonic device fabrication. Work closely with process engineers and other internal stakeholders to meet process and equipment milestones.Process Development & Integration: Develop and optimize process modules (etch, deposition, lithography, diffusion, metallization, etc.) for InP-based PICs (Photonic Integrated Circuits). Ensure process robustness and repeatability across the full device flow.Yield & Reliability Engineering: Establish process monitoring metrics, inline metrology strategies, and SPC to drive yield improvement. Identify root causes of process excursions or device failures; lead corrective actions using FA tools and DOE methodology.Cross-Functional Collaboration: Interface with device design, test, and packaging teams to ensure manufacturability and alignment on performance targets.Documentation & Technology Transfer: Develop and maintain detailed process documentation, FMEA analyses, and qualification reports. Support the transfer of developed processes from R&D to pilot and volume production. BS/MS/PhD in Electrical Engineering, Materials Science, or related field.Hands-on experience in compound semiconductor fabrication, with a strong preference for InP-based photonics.Understanding of semiconductor process integration, yield improvement methodologies, and cleanroom practices.Experience with fab tool bring-up and qualification, including troubleshooting and maintenance support.Strong problem-solving skills, with a data-driven mindset and familiarity with tools like JMP, Python and MES/SPC software packages.Experience with SPC, Design for Manufacturing (DfM), and six-sigma principles for continuous improvement is a plus.Excellent communication and teamwork skills; able to work in a fast-paced startup or ramp-up environment. What We OfferA chance to contribute to cutting-edge photonic technologies in a globally recognized company.A collaborative, innovative work environment with multidisciplinary technical teams.The opportunity to directly impact the development of high-performance optical networking solutions at Nokia. If you're passionate about advancing optical communication technology and eager to tackle challenging technical problems in PIC development, we invite you to apply.
