Location: Alhambra, CA (Onsite) Position Summary: The Process Integration Engineer – InP Wafer Fab position is responsible for end-to-end ownership of Indium Phosphide ( InP ) wafer fabrication process flows supporting the manufacturing of DFB lasers, Semiconductor Optical Amplifiers (SOAs), and Gain Chip (GC) products. This role serves as the technical integrator across all wafer fab process modules, ensuring compatibility, robustness, and high-yield performance of the complete device fabrication flow . The position focuses on cross-module coordination, yield analysis, failure analysis, and root-cause resolution to enable stable manufacturing operations and successful new product introduction. The role requires strong systems-level understanding of InP device fabrication, data-driven problem solving, and close collaboration with process, device, reliability, and manufacturing teams. Responsibilities : End-to-End Process Flow Ownership and Integration (35%) : Own and manage the complete InP wafer fabrication process flow from epitaxy through backend processing Ensure process compatibility and robust integration across lithography, etch, deposition, metallization, and test modules Define and maintain integration requirements including layer interactions, thermal budgets, process margins, and sequence dependencies Serve as the primary technical owner for process flow integrity and change impact assessment Yield Analysis, Excursion Response, and Continuous Improvement (25%) : Lead yield analysis efforts to identify yield limiters, systematic defects, and process interactions Drive excursion response activities, including rapid containment, root-cause identification, and corrective action implementation Analyze inline and electrical test data to identify process trends and emerging risks Partner with manufacturing and process teams to implement yield improvement and defect reduction initiatives Failure Analysis and Root-Cause Resolution (20%) : Lead and coordinate failure analysis (FA) activities using structured problem-solving methodologies (e.g., 8D, Six Sigma) Identify defect mechanisms and process-induced failure modes through cross-functional investigation Leverage FA techniques such as optical inspection, SEM, FIB, SIMS, and electrical analysis (directly or via partners) Ensure corrective and preventive actions are implemented and verified for effectiveness New Product Introduction and Technology Support (10%) : Support new product introduction (NPI), process transfers, and technology changes within the InP wafer fab Evaluate integration risks associated with new designs , materials, or process changes Collaborate with device and design teams to ensure manufacturability and integration robustness Documentation, Process Control, and Manufacturing Support (10%) : Author and maintain process flows, integration specifications, travelers, and control plans Define requirements for process control monitor structures (PCM/TLM) and ensure implementation in design layouts Support day-to-day manufacturing operations by providing technical guidance and integration expertise Ensure documentation accuracy and compliance with internal quality and manufacturing standards Minimum Qualifications : Bachelor’s degree or higher in Electrical Engineering, Materials Science, Physics, Chemical Engineering, or a related field required Minimum of 5+ years of experience in semiconductor process integration or device fabrication Strong hands-on understanding of InP -based or III-V compound semiconductor wafer fabrication processes Demonstrated experience with yield analysis, defect reduction, and root-cause methodologies Experience working across multiple wafer fab process modules in a manufacturing environment Strong systems-level understanding of semiconductor device fabrication and process interactions Proficiency in data analysis and statistical process control (SPC) Ability to drive alignment and decision-making across cross-functional engineering teams Preferred experience with DFB lasers, SOAs, gain chips, or photonic device manufacturing Familiarity with reliability testing, qualification flows, and product lifecycle support preferred Experience supporting high-mix, low-volume manufacturing environments preferred The intent of this job description is to describe the major duties and responsibilities performed by incumbents of this job. Incumbents may be required to perform job-related tasks other than those specifically included in this description. All duties and responsibilities are essential job functions and requirements and are subject to possible modification to reasonably accommodate individuals with disabilities. A reasonable estimate of the pay range for this position is $93,000 - $135,000. There are several factors taken into consideration in determining base salary, including but not limited to: job-related qualifications, skills, education and experience, as well as job location and the value of other elements of an employee’s total compensation package. #LI-Onsite
Here's how to pick the right one and stand out in your application.
144.883Jobs
31.687IN
81%EN
That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
