Digital solutions are hitting a power wall as we approach the physical limits of traditional silicon. Conquering this bottleneck means rethinking the fundamental architecture of inference compute. The industry's current path can't meet the need, so we're taking a different approach.\nInstead of traditional electronic circuits, we use silicon photonics and an active, programmable metasurface to perform matrix multiplications at the speed of light. Our optical cells are 10,000x smaller than traditional photonic components, enabling unprecedented density. By using photonics instead of electricity, our chips become more efficient as they scale. This architecture will deliver up to 100 times the energy efficiency of existing solutions while significantly improving performance for large-scale AI inference.\nWe’ve assembled a world-class team of industry veterans and recently raised a $110M Series A led by Gates Frontier. Participants include M12 (Microsoft’s Venture Fund), Carbon Direct Capital, Aramco Ventures, Bosch Ventures, Tectonic Ventures, Space Capital, and others.\nJoin us and shape the future of computing!\nPosition Overview:\nWe are seeking a seasoned Principal Analog Design Engineer to play a vital role in developing cutting-edge full-custom electronic transceiver components that interface directly with our custom silicon photonics and are essential to our revolutionary photonic AI platform. You will be responsible for the full lifecycle of analog blocks, from specification and architecture down to tape-out-ready layout. Success in this role requires a deep understanding of transistor-level circuit design, linearity, noise performance, and signal integrity in CMOS processes up to GHz speeds. If you possess a proven track record of designing robust, ultra-fast analog circuits and are eager to work at the intersection of electronics and photonics, you will make a defining impact on the future of optical computing.\nLocation: San Jose, CA or Hsinchu, Taiwan. Full-time onsite position.\nKey Responsibilities:\nDesign, simulate, and verify high-speed analog circuits, including but not limited to high-swing drivers, transimpedance amplifiers, ADCs, DACs, and PLLs, in deep-submicron CMOS technologies.\n\nDefine architecture and specifications for electronic blocks based on system-level requirements.\n\nPerform full-custom schematic capture, advanced analog simulations, and complete physical layout, including DRC/LVS, of critical analog blocks using Cadence Virtuoso.\n\nEnsure rigorous signal integrity and power integrity across all high-speed interconnects.\n\nConduct layout floor planning.\n\nConduct post-layout extraction and simulation to validate performance against parasitic effects.\n\nCollaborate closely with the Photonics and Digital teams to optimize the electro-optic interface, maximizing performance across the combination of disciplines.\n\nCollaborate with team members to prepare and conduct the bench characterization and production tests.\n\nQualifications:\nMS or PhD in Electrical Engineering.\n\n10+ years of professional experience in full-custom analog integrated circuit design, 5+ years of dedicated experience in either GHz-speed RF or GHz-speed broadband analog design.\n\nDemonstrated expert proficiency in the Cadence tool suite, specifically Virtuoso schematic, simulation, and custom layout.\n\nDeep understanding of semiconductor device physics, linearity, noise analysis, and high-frequency circuit theory.\n\nProven track record of taking high-speed analog blocks from concept to mass production (successful tape-outs).\n\nPreferred Skills:\nA background in photonic transceivers or optical communication electronics.\n\nExtensive design experience in TSMC latest technology nodes, such as N5P, N3P, and N2P.\n\nExperience designing high-speed data converters.\n\nExperience designing low-jitter clocking circuits, including PLLs.\n\nProficiency in electromagnetic simulation tools such as EMX or HFSS.\n\nExperience with frequency domain simulation in Spectre RF.\n\nWhat We Offer\nThis is an opportunity to play a pivotal role in an innovative startup redefining the future of AI hardware. Work on game-changing technology at the intersection of photonics and AI as part of a collaborative, brilliant team. You’ll contribute to a platform that redefines computational performance and accelerates the future of artificial intelligence. Come help us bring this transformative technology to the world.\nBenefits\nJoin a team that invests in your future and your well-being. At Neurophos, we offer:\n100% coverage of base health plan premiums for you and your dependents, plus HSA contributions.\n\nUnlimited PTO. No rigid vacation banks, just a focus on delivery.\n\n401(k) matching and stock option opportunities to ensure our success is your success.\n\nFull suite of voluntary benefits, including Dental, Vision, Life, Hospital, Critical Illness, and Accident insurance.\n\nPersonalized Benefits.
