We are a Tokyo-based technology company specialising in end-to-end support for generative AI agents, from strategic planning and implementation through to ongoing operation. Our work combines proprietary product development with tailored solutions for enterprise clients, helping organisations apply generative AI securely and effectively in real-world environments.
The company offers an innovative, technically ambitious setting where engineers can work across product and client projects. You will collaborate with colleagues from different disciplines, contribute to meaningful AI initiatives and help shape engineering practices as the business grows. We value ownership, thoughtful communication, quality and practical problem-solving, while providing the tools and environment needed to deliver high-impact work.
As a Software Engineer, you will design, build and operate robust applications for both internal products and client solutions. You will contribute across the full development lifecycle, translating requirements and design principles into reliable, maintainable software.
Your responsibilities will include developing backend and frontend applications and APIs using TypeScript, implementing generative AI functionality with leading large language models, and improving prompts, agents and evaluation processes. You will also address enterprise-grade operational requirements, including asynchronous processing, retries, audit logs, role-based access control, monitoring and rate control.
The role involves securely integrating client systems such as core databases, workflows and document management platforms. You will contribute to testing, observability, performance and vulnerability improvements, as well as design reviews, code reviews, technical decisions and documentation.
