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.

Mission
You will build the control software for our Y-1 machine vertically — from device drivers up to the GUI and calibration API that physicists use every day. This is a machine-facing role: you own a control feature end-to-end, from the hardware signal to the experimenter's screen, without handing it off across team boundaries. Because the work is hardware-coupled — debugging against the real machine, cameras, SLMs, and AWGs in the lab — this is an on-site role based in Kyoto. Expect incomplete requirements and shifting constraints. You'll make progress with sound engineering judgment and harden things as the machine stabilizes — not wait for a perfect spec.
What you'll do
- Own all layers, no handoffs: carry a control feature from real-time device code up to the experimenter's GUI, across team boundaries
- Device layer: EMCCD camera (ROI, atom detection, thresholding), SLM (hologram generation, uniformity, fast switching), AWG (rearrangement waveform synthesis)
- Middleware: sequence / subsystem / connection-map / hardware-setting modules, being able to work with several vendors to avoid platform lock-in
- User-facing layer: the unified GUI, calibration API, and operator tooling that experimenters rely on
- Image processing & algorithms for atom detection, rearrangement, and calibration automation
- Hardware-coupled integration testing and calibration automation, working directly with physicists and the HW group
Must-have
- High level C/C++ and Python — able to lead design and implementation
- Demonstrated vertical ownership: you have built and owned a feature from a low-level layer (driver / firmware / device code) all the way up to its user-facing application or GUI. This top-of-stack reach is what makes the role full-stack.
- Linux development experience, including low-level I/O, timing, or interrupt-level work
- On-site in our Kyoto office/lab at least 3 days per week (Kyoto-based)
- Business-level English for a global team
- Self-directed learner who picks up new languages, frameworks, and unfamiliar domains from papers and specs
Nice-to-have
- Embedded Linux / Yocto, device drivers, MCU firmware
- FPGA-coupled software design, or FPGA development (Verilog / VHDL)
- Image processing and/or algorithm development
- Modern languages (Go, Rust); a polyglot style across the stack
- Real-time / sub-microsecond timing control
- Front-end frameworks (React / Next.js, TypeScript) — the specific stack is flexible
- Control of optical / laser / vacuum physics instruments
- Interest or experience in machine learning
- Technical specification authoring for multi-module systems
Why this role
- Own a feature from "hardware signal" to "experimenter's screen" — no layer is off-limits to you
- Build the control stack 0→1 as a founding-era member
- Anchor on deep C/C++ while extending into frontend, algorithms, and embedded on your own terms
- Sit in the same team as the quantum physicists and scientists to turn experimental requirements directly into software
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.
