Senior/Staff Process Integration Engineer

About This Role

• We are seeking a highly skilled Senior Process Integration Engineer to lead the development and optimization of Indium Phosphide (InP) based Edge Emitting Lasers (EELs).
• In this role, you will be the bridge between design and manufacturing, ensuring that our high-performance optoelectronic devices transition from concept to high-volume production with world-class reliability and yield.
• You’ll be working at the frontier of photonics, handling complex material systems and sophisticated fabrication sequences to power the next generation of optical communications and sensing technologies.
• Core Responsibilities Process Flow Ownership: Design, implement, and manage the full end-to-end fabrication flow for InP-based EELs (e.g., Fabry-Pérot, DFB, and DBR lasers).
• Yield & Performance Optimization: Identify and resolve integration bottlenecks.
• Use Statistical Process Control (SPC) and Design of Experiments (DOE) to improve device electro-optical performance (threshold current, wall-plug efficiency, and slope efficiency).
• Cross-Functional Collaboration: Partner with Epitaxy (MOCVD) teams to optimize regrowth interfaces and with the Design team to ensure Layout-to-Mask integrity.
• Advanced Fabrication Management: Oversee critical steps including dry/wet etching (ICP/RIE), dielectric deposition (PECVD/ALD), metallization etc.
• Failure Analysis: Coordinate Root Cause Analysis (RCA) on fabrication failures using SEM, TEM, and FIB diagnostics to drive continuous improvement.
• Key Technical Requirements Materials Expertise: Deep understanding of III-V compound semiconductors, specifically the GaAs/InP/InGaAsP/material systems.
• Device Physics: Strong grasp of semiconductor laser physics Fabrication Proficiency: Hands-on experience or good understanding on photolithography, etching, thin film Characterization: Understanding laser characterization data and correlating results back to specific process modules.
• Qualifications Education: PhD or Master’s degree in Electrical Engineering, Physics, Materials Science, or a related field.
• Experience: 5+ years of direct experience in III-V semiconductor processing Software: Proficiency in JMP, or Python for data analysis; Mindset: A methodical troubleshooter who thrives in a cleanroom environment and enjoys the "detective work" of process integration.
• We will also consider qualified applicants with arrest and conviction records consistent with local law.
• If you are located outside USA, please be sure to fill out a home address as this will be used for future correspondence.
