DevOps / Site Reliability Engineer

Location: Kyoto, Japan Employment Type: Full-time Salary: JPY 8,000,000–15,000,000 per year (depending on experience) Build the Infrastructure Behind the World's Next Generation of Quantum Computers A well-funded quantum computing startup in Japan is looking for an experienced DevOps / Site Reliability Engineer to build the operational foundation for a next-generation neutral-atom quantum computer. Founded by researchers from one of Japan's leading universities, the company has secured approximately JPY 700 million in funding and is backed by leading international investors and major government R&D programs. This is a unique opportunity to build the reliability, deployment, and operational infrastructure that will power a real quantum computer. Unlike traditional DevOps roles, you'll work directly alongside quantum physicists, hardware engineers, and software engineers to help transform cutting-edge research into a reliable production system. About the Role As the company transitions from experimental research to building a production-ready quantum computer, reliability becomes mission-critical. This is a 0→1 Site Reliability Engineering role. You'll establish the DevOps foundation from scratch, creating deployment pipelines, monitoring systems, testing infrastructure, and operational processes that enable continuous operation of quantum hardware. You'll take ownership of the entire operational lifecycle, allowing research and engineering teams to focus on developing the next generation of quantum technologies.
