Duties & Responsibilities\nDevelop silicon photonics and heterogeneously integrated device and circuit concepts for datacom, optical I/O, and related platforms.\n\nModel optical, electrical, thermal, and link-level behavior to guide design choices before prototype builds.\n\nDefine prototype verification objectives and use early trial results to refine designs.\n\nApply process-integration awareness to keep designs compatible with fabrication, test, and metrology constraints.\n\nEvaluate heterogeneous integration options when they may improve silicon photonics performance or functionality.\n\nKey Responsibilities\nAdvanced Technical Assessment and Incubation\nShape early-stage concepts, feasibility objectives, risk-reduction plans, and prototype approaches for CTO Office topics, including possible architectures such as CPO and optical I/O.\n\nLead technical evaluations, modeling, design reviews, and trade-off studies with internal or external contributors.\n\nDevelop recommendations on performance, manufacturability, integration path, scalability, reliability, and transition readiness.\n\nRoadmap Input and Technology Direction\nContribute technical input to roadmap discussions in optical interconnect, CPO / optical I/O, AI/HPC infrastructure, silicon photonics, detector technologies, and related platforms.\n\nTranslate emerging technology options into milestones, risks, decision points, and recommended next steps\n\nCross-Functional Execution and Communication\nCoordinate work across design, PDK, fabrication, process-integration, packaging, reliability, test, and external partner teams, including tapeout readiness and handoff to fabrication partners.\n\nPrepare concise design reviews, prototype summaries, and recommendations for senior technical, product, and business stakeholders.\n\nSupport partner, supplier, university, and ecosystem discussions when technical representation is needed.\n\nEducation & Experience\nPh.D. in Electrical Engineering, Applied Physics, Photonics, Materials Science, or related field.\n\n>7 years of experience in silicon photonics design, integrated photonics R&D, SiP fabrication-aware design, prototype development, device verification, or related semiconductor photonics work.\n\nHands-on SiP fabrication experience or close collaboration with SiP fabrication teams is required, with sufficient process understanding to design realistic prototype trials and interpret results.\n\nThe role benefits from experience with heterogeneous integration of non-silicon materials on silicon, including wafer bonding, die bonding, transfer printing, direct bonding, adhesive bonding, or thin-film transfer.\n\nExperience connecting design choices to optical, electrical, thermal, mechanical, reliability, process-integration, and packaging outcomes for photonic or optoelectronic devices.\n\nExperience with simulation, data analysis, DOE, documentation, and R&D decision support using Python, Lumerical, COMSOL, JMP, Excel, or equivalent.\n\nPackaging experience is a plus, including co-packaged optics, optical coupling, fiber attach, PIC / EIC integration, OSAT engagement, or prototype assembly.\n\nSkills\nStrong foundation in silicon photonics design, device physics, test vehicles, materials interfaces, PDK-based design, and process-integration constraints.\n\nFamiliarity with PDKs from multiple fabs, silicon photonics tapeout flows, and layout reviews is valuable.\n\nStructured problem-solving ability and comfort defining technical direction from trade-offs, incomplete data, and early prototype results.\n\nExperience with silicon photonics tapeouts is a valuable strength for this role.\n\nCollaborative style and ability to influence across design, process integration, packaging, reliability, business groups, suppliers, and external partners.\n\nClear written and verbal communication with senior technical, product, manufacturing, and business audiences.\n\nWorking Conditions\nIn-person position based in Santa Clara, California.\n\nCombination of design analysis, prototype planning, R&D verification, cross-functional collaboration, and external ecosystem engagement.\n\nPhysical Requirements\nAbility to work in laboratory or cleanroom-adjacent environments, follow PPE requirements, handle wafers or samples when needed, and review process, metrology, and test data.\n\nSafety Requirements\nAll employees are required to follow the site EHS procedures and Coherent Corp. Corporate EHS standards.\nQuality and Environmental Responsibilities\nCulture Commitment\nEnsure adherence to company’s values (ICARE) in all aspects of your position at Coherent Corp.:\nIntegrity - Create an Environment of Trust\nCollaboration - Innovate Through the Sharing of Ideas\nAccountability - Own the Process and the Outcome\nRespect - Recognize the Value in Everyone\nEnthusiasm - Find a Sense of Purpose in Work\nCoherent Corp. is an equal opportunity/affirmative action employer.
