At Xanadu, we are learners, innovators, researchers, collaborators and problem solvers. We are creating something that has never been built before. What we are doing is extremely hard, the classic moon shot. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems, and literally change the world. And that is something to be excited about!\nYour role and responsibilities:\n As an industry leader in photonic quantum computing, Xanadu takes hardware very seriously! In this role, you will work within the Fabrication Process Engineering team to deliver Xanadu’s photonic quantum computing hardware. With your deep technical expertise and strong experience in photonics fabrication process development and process integration, you will be responsible for developing process integration schemes used to build critical components of Xanadu’s quantum computing hardware.\nProcess Integration & Quantum Hardware Development:\nCoordinate between several internal component teams to ensure all hardware requirements are satisfied in delivered chips and circuits.\nInnovate in the space of photonic process development and process integration, especially with respect to ultra-low loss components.\nCollaborate with internal and external photonics process engineers to refine fabrication procedures for ultra-low loss photonic quantum computing chips.\nWork with Xanadu’s foundry partners to continuously improve lithography approach while balancing competing fabrication requirements.\nDeliver integrated quantum photonics chips and circuits containing multiple active and passive components.\nLithography & Tapeout Ownership:Build, define, and own the entire photolithography and tapeout module from layout receipt to final wafer patterning.\nReceive GDS design files and manage the tapeout cycle with external mask shops.\nDefine the exact specifications for OPC aggressiveness, dummy fill density rules, and Optical Rules Check (ORC) targets.\nDevelop and enforce the Lithography Design Rule Manual and provide critical Design for Manufacturing (DFM) feedback to layout teams.\nDefine scanner illumination conditions and tune Numerical Aperture/Sigma settings to maximize process windows.\nExecute rigorous focus/exposure matrices, optimize photoresist/BARC chemistries, and establish metrology baselines to ensure strict CD and overlay control.\nStay abreast of new developments in the fields of photonics fabrication process development and advanced patterning.\nBasic qualifications and experience:\n\nMS, or Ph.D. in Electrical Engineering, Physics, Materials Science, Chemical Engineering, or a related technical field.\n5+ years experience in a foundry environment for semiconductor and/or integrated photonics products, including experience owning lots, working with an MES, etc.\nFamiliarity with standard semiconductor and photonics metrology and failure analysis techniques, including some subset of: SEM, TEM, AFM, defect inspection, ellipsometry, XRR/XRD, SIMS, Raman spectroscopy.\nFamiliarity with photonic components, such as waveguides, beamsplitters, resonators, MZIs, etc.\nDeep, hands-on expertise with advanced 300mm scanners.\nDemonstrated experience managing tapeout cycles, specifying mask requirements, and reviewing ORC/OPC verification data.\nAbility to tackle challenging problems and develop innovative solutions.\nExcellent communication skills and strong sense of teamwork.\nPreferred qualifications and experience:\n\nExperience building lithography modules within a mature technology flow.\nStrong understanding of advanced mask writing technologies and the fundamental physics of lithographic imaging.\nExperience owning lots in SiView MES.\nExperience with product development cycle from R&D through volume ramping.\nExperience in photonic quantum computing hardware development.\nDemonstrated track record of delivering finished integrated photonics products.\nExperience working in fabless companies.\nPreferred location: Albany, NY area.\nThis is for a new position. Your base salary will be determined based on your location, experience, and internal benchmarks. The base salary range is 110,000 - 150,000 USD. You will also be eligible for equity and benefits.\nOur values are important. They are fundamental and lay the foundation for culture at Xanadu.
