While neutral-atom systems offer significant advantages in scalability, challenges remain in areas such as fault tolerance and computational performance. Yaqumo combines the expertise of both research groups to address these challenges.\nIn 2025, the company secured approximately JPY 700 million in funding and was selected for a major NEDO (New Energy and Industrial Technology Development Organization) program. We are currently developing ytterbium-based quantum gates, control systems, and quantum error correction technologies, with the goal of delivering a prototype fault-tolerant quantum computer by FY2027.\nOur long-term vision is to bring neutral-atom quantum computing into practical use and tackle societal challenges that are beyond the capabilities of conventional computing.\nRecent News\nGlobal Quantum VC Quantonation Selects Yaqumo as Its First Japanese Investment https://yaqumo.com/en/news/287/(https://yaqumo.com/en/news/287/)\nYaqumo, NKT Photonics, and Hamamatsu Photonics Sign MOU on Development and Industrialization of Advanced Photonic Systems for Quantum Computing https://yaqumo.com/en/news/337/(https://yaqumo.com/en/news/337/)\nAlumni Ventures Makes First-Ever Japan Investment in Yaqumo to Back the Future of Neutral-Atom Quantum Computing https://yaqumo.com/en/news/351/(https://yaqumo.com/en/news/351/)\nJob Summary\nIn this role, you will take end-to-end ownership of the laser and optical systems, Yaqumo's neutral-atom quantum computer. Your responsibilities span the full lifecycle of the laser platform-from optical system assembly and alignment to the design and improvement of laser stabilization systems, performance evaluation, maintenance, and troubleshooting.\nWorking closely with our experimental team, you will design and implement laser and optical systems that meet evolving experimental requirements while ensuring they remain reliable and experiment-ready on a daily basis. Your work will directly improve the stability and reliability of the laser infrastructure that supports our quantum computing research.\nBecause this role involves hands-on alignment, evaluation, maintenance, and troubleshooting of experimental hardware, this position is based at our Kyoto laboratory.\nOur research environment evolves rapidly, and system requirements are not always fully defined in advance. We are looking for someone who enjoys identifying technical challenges proactively and continuously improving the reliability and maintainability of complex laser and optical systems.\nResponsibilities\nBuild and align laser optical systems Assemble, align, and commission laser and optical systems based on design requirements, including optical alignment, polarization adjustment, and beam shaping, to bring systems into an experiment-ready state.\nMaintain experiment-ready laser systems Maintain laser and optical systems in a stable operating condition by troubleshooting lock failures, optical misalignment, and other hardware issues, while continuously improving overall system stability.\nDesign and improve laser stabilization systems Design, implement, tune, and optimize frequency and intensity stabilization systems for lasers. Evaluate system performance and improve robustness to minimize lock failures and enable rapid recovery.\nDesign and evaluate laser and optical systems Work with AMO researchers to define system requirements-including frequency stability, polarization control, modulation schemes, and intensity noise-and design complete optical systems through appropriate selection of optical components and modulation techniques. Evaluate system performance against experimental requirements.\nPreventive maintenance and documentation Establish preventive maintenance practices through regular inspection, health monitoring, spare-part management, and preparation of technical documentation and recovery procedures, helping standardize maintenance processes and facilitate knowledge transfer.\nVendor management and technical collaboration Coordinate repair and RMA processes and collaborate with external vendors and optical technology partners.\nRequired Qualifications\nCandidates should satisfy multiple of the following qualifications.\nSolid understanding of fundamental optics, including Gaussian beams, polarization, and optical interference, with the ability to quantitatively evaluate optical alignment and system performance\nAt least 3 years of hands-on industrial or academic experience working with laser or optical systems\nExperience using optical measurement equipment such as power meters, beam profilers, oscilloscopes, and spectrum analyzers\nStrong troubleshooting skills, including systematic root-cause analysis and clear documentation of findings and corrective actions\nFundamental knowledge of feedback control systems or practical experience developing stabilization systems\nPractical experience with RF analog electronics and a solid understanding of RF fundamentals\nPreferred Qualifications\nExperience stabilizing laser frequency, phase, or intensity\nExperience with optical cavities and external cavity diode lasers (ECDLs)\nExperience evaluating PID control systems, loop transfer functions, control bandwidth, phase margin, and gain margin\nExperience designing and building RF or servo circuits\nExperience controlling optical frequency or optical intensity using AOMs, EOMs, PLLs, or frequency synthesizers\nExperience with fiber coupling and polarization-maintaining optical fibers\nExperience with nonlinear optics, including wavelength conversion using nonlinear crystals\nWhy this role\nDirectly improve the speed and quality of quantum computing research by increasing the stability and maintainability of the laser infrastructure.\nDesign, optimize, and maintain laser systems whose performance directly impacts day-to-day experimental research.\nApply your expertise in laser and optical engineering to enable researchers to focus on quantum physics and experimental development.\nAs an early member of the company, you will help shape-not simply maintain-the next generation of laser and optical infrastructure supporting our quantum computing platform.\nHiring Process\nCV Review → First Interview → Second Interview → Final Interview\nDepending on the position, candidates may be asked to complete a technical assignment after the first interview.\n We place a strong emphasis on mutual understanding throughout the hiring process. Depending on the role and evaluation process, additional interviews, informal meetings with team members, or offer discussions may be arranged.\nEmployment Details\nEmployment Type: Full-time\nCompensation: JPY 8M-15M, depending on experience and qualifications\nWork Schedule: Discretionary Labor System for Professional Work (R&D)\nProbation Period: 2 months (no changes to employment conditions during probation)\nWork Location: 2wa Room313b, 31-1 Shōgoin Rengezo-cho, Sakyo-ku, Kyoto, Japan 606-8357, Japan\nWorking Hours: Discretionary Labor System (deemed working hours: 8 hours/day).
