Staff Wet Etch Process Engineer

At Nokia Optical Networks, advanced photonic technologies become scalable products powering the world's communication infrastructure. Our team develops and manufactures cutting-edge Indium Phosphide (InP) photonic integrated circuits (PICs), enabling coherent optics, high-speed transceivers, tunable lasers, optical amplifiers, and next-generation networking solutions. As a Staff Wet Etch Process Engineer , you will develop, integrate, and optimize wet etch and wet clean processes used in the fabrication of advanced photonic devices. You will work hands-on with wet processing equipment, chemical delivery systems, consumables, and metrology systems to improve dimensional control, selectivity, surface morphology, contamination performance, yield, and manufacturability. MS or PhD in relevant engineering or science discipline. 5+ years semiconductor, photonics, or process engineering experience. Strong understanding of wet processing, surface chemistry, contamination control, DOE, and SPC. Strong ownership mindset and ability to independently drive projects and deliver results. Ability to prioritize and respond quickly to manufacturing challenges. Preferred Qualifications Experience with semiconductor wet benches and automated wet processing equipment. Experience processing InP, GaAs, SiN, silicon photonics, or III-V technologies. Passion for manufacturing excellence and continuous improvement. Proven ability to thrive in a fast-paced fab environment balancing production and development priorities.
