Process Engineer - Semiconductor R D Edison is seeking an experienced Process Engineer to lead the development and optimization of advanced III-V semiconductor fabrication processes, with a focus on GaAs-based laser devices. This is a hands-on, technical role spanning both research and development and device fabrication. You will play a key role in developing robust, repeatable processes and supporting the transition of experimental device concepts into reliable fabrication flows. What You'll Be Doing Own and develop end-to-end III-V device fabrication processes Work across lithography, dry/wet etching, thin film deposition, and metallization Design and execute process development, qualification, and yield improvement experiments Integrate unit processes into full device fabrication flows for photonic structures Troubleshoot process and device performance issues using data-driven analysis Collaborate closely with academic researchers and external partners on process transfer and optimization Supervise and support a process technician in daily cleanroom operations Maintain process documentation, control plans, and fabrication records Operate within a multi-user cleanroom with dynamic priorities and shared equipment What You'll Need Hands-on experience in semiconductor cleanroom process engineering Strong background in lithography, etching, and thin film deposition techniques Experience with III-V materials (e.g., GaAs, InP, GaN) strongly preferred Understanding of process control, yield improvement, and root cause analysis Experience working in both R D and fabrication environments Ability to work collaboratively across technical and academic teams Prior experience mentoring or supervising junior staff is an advantage Degree in Electrical Engineering, Materials Science, Physics, or a related field Company This is a unique opportunity to work on next-generation semiconductor and photonic device technologies for a VC backed startup in a highly collaborative research environment, with direct impact on advanced device development and process innovation.
