We are looking for a Principal / Senior Silicon Photonics Process Engineer to lead process integration, NPI execution, and foundry collaboration for advanced silicon photonics platforms. Based in Asia, you will serve as the primary technical interface with external foundry partners in Asia and internal design teams in the U.S., owning process development, yield optimization, manufacturability, and program delivery. This is a fab-facing integration + program leadership role (not a design role). Foundry Interface & Process IntegrationAct as on-site technical lead for silicon photonics at the foundryDrive process integration across FEOL, BEOL, device, and module layersDefine and manage process development plans and technology roadmapsAlign design requirements with foundry capabilities NPI, Yield & Manufacturing ExecutionLead New Product Introduction (NPI) from tape-out through qualification (PRQ) and rampOwn yield learning, failure analysis, and process convergenceEnsure manufacturability targets (yield, cost, cycle time, reliability)Manage wafer lots, tracking schedule, risk, and quality Program & Cross-Functional LeadershipAct as primary fab contact for product integrationInterface with design (IPS), process, test, Q&R, planning, OSAT, and business unitsSupport customer-facing technical discussions (PL/BU engagement)Lead technology transfer to high-volume manufacturing Process Development & DFMDefine: Process flows, integration schemesDesign rules and DFM guidelinesProcess capability documentationRun DOE, SPC, and advanced data analytics to improve process performance You have:MSc or Ph.D. in Electrical Engineering, Materials Science, Physics, or related field5–10+ years experience in: Silicon photonics / semiconductor process integrationFoundry engagement and tape-out executionStrong experience in: Yield optimization, DOE, SPCProduct lifecycle: NPI → qualification → rampExcellent cross-functional leadership and communication skillsExperience in coherent optics or datacenter interconnectsProven track record in technology transfer & high-volume manufacturingFamiliarity with: Cadence Virtuoso, OptoCompilerPython, JMP, SQL for data analysisExperience with customer-facing program delivery
