Company Overview
Yaqumo is a quantum computing startup founded on research originating from the Takahashi Laboratory at Kyoto University and the Omori Laboratory at the Institute for Molecular Science (IMS).
Our core technology is based on neutral-atom quantum computing, a promising architecture known for its scalability to large numbers of qubits. 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.
In 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.
Our 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.

Job Summary
In 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 platformfrom optical system assembly and alignment to the design and improvement of laser stabilization systems, performance evaluation, maintenance, and troubleshooting.
Working 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.
Because this role involves hands-on alignment, evaluation, maintenance, and troubleshooting of experimental hardware, this position is based at our Kyoto laboratory.
Our 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.
Responsibilities
Build 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.
Maintain 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.
Design 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.
Design and evaluate laser and optical systems
Work with AMO researchers to define system requirementsincluding frequency stability, polarization control, modulation schemes, and intensity noiseand design complete optical systems through appropriate selection of optical components and modulation techniques. Evaluate system performance against experimental requirements.
Preventive 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.
Vendor management and technical collaboration
Coordinate repair and RMA processes and collaborate with external vendors and optical technology partners.
Required Qualifications
Candidates should satisfy multiple of the following qualifications.
Solid understanding of fundamental optics, including Gaussian beams, polarization, and optical interference, with the ability to quantitatively evaluate optical alignment and system performance
At least 3 years of hands-on industrial or academic experience working with laser or optical systems
Experience using optical measurement equipment such as power meters, beam profilers, oscilloscopes, and spectrum analyzers
Strong troubleshooting skills, including systematic root-cause analysis and clear documentation of findings and corrective actions
Fundamental knowledge of feedback control systems or practical experience developing stabilization systems
Practical experience with RF analog electronics and a solid understanding of RF fundamentals
Preferred Qualifications
Experience stabilizing laser frequency, phase, or intensity
Experience with optical cavities and external cavity diode lasers (ECDLs)
Experience evaluating PID control systems, loop transfer functions, control bandwidth, phase margin, and gain margin
Experience designing and building RF or servo circuits
Experience controlling optical frequency or optical intensity using AOMs, EOMs, PLLs, or frequency synthesizers
Experience with fiber coupling and polarization-maintaining optical fibers
Experience with nonlinear optics, including wavelength conversion using nonlinear crystals
Why this role
Directly improve the speed and quality of quantum computing research by increasing the stability and maintainability of the laser infrastructure.
Design, optimize, and maintain laser systems whose performance directly impacts day-to-day experimental research.
Apply your expertise in laser and optical engineering to enable researchers to focus on quantum physics and experimental development.
As an early member of the company, you will help shapenot simply maintainthe next generation of laser and optical infrastructure supporting our quantum computing platform.
Hiring Process
CV Review → First Interview → Second Interview → Final Interview
Depending on the position, candidates may be asked to complete a technical assignment after the first interview.
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.
