Job Description: 【Company Overview】 The company operates with the mission of “Reinventing value creation systems to propel humanity forward,” leveraging cutting-edge generative AI technologies to support transformative change across a wide range of enterprises. It provides two core solutions: “Anews,” a platform for unified access to internal and external information, and “SAT (Stockmark A Technology),” which structures all types of data into valuable corporate assets. The company also supports the development of enterprise-specific generative AI models and custom system implementations. Its primary focus is currently on R&D divisions of major Japanese manufacturing companies, with adoption already underway at over 30% of the Nikkei 225 and more than 250 companies. Looking ahead, the company aims to expand from manufacturing R&D to broader domestic enterprise clients and eventually to global markets. The company is also investing heavily in the development of a Japan-originated LLM optimized for the Japanese language and business domains, having released a proprietary 100-billion-parameter model in May 2024. In October 2024, it completed a Series D funding round of ¥4.5 billion, bringing total funding to ¥8.8 billion. With its workforce now exceeding 100 employees, the company is actively hiring to accelerate further growth. 【Current Issues】・The company recently completed a ¥4.5 billion Series D funding round, and in order to elevate its product to the next level, it is essential to accelerate value validation in collaboration with product managers and designers, and actively drive the implementation of new features. ・With a growing user base, it has become increasingly critical to strengthen the development structure to rapidly advance both new feature development and ongoing improvements—such as addressing user feedback, ensuring stable product operations, and optimizing the development environment. 【Responsibilities】 You will be responsible for the development of Anews, including its web interface, batch processing, and mobile application. You will begin by working in your area of expertise, with the expectation of eventually expanding into full-stack development. In addition to core development tasks, depending on your interests and preferences, you will also have the opportunity to take on challenges such as architecture design and planning for large-scale and complex development projects, driving initiatives in collaboration with research and BizDev teams, and managing development teams. The company also plans to promote development using machine learning, particularly natural language processing, in the near future. Examples of upcoming large-scale and complex development projects include: ・Designing and developing a feature that leverages LLMs to summarize accumulated user information and extract actionable insights. ・Developing and improving the performance of a personalized recommendation system that delivers higher-quality information tailored to each user. ・Designing and developing functionality to visualize insights derived from information shared within an organization. ■Specifically [Front-end Domain] ・Planning and designing new features, front-end development and performance improvement using Vue.js ・Mobile app development using Flutter ・Improving development experience by improving development infrastructure and refactoring ・Designing and implementing common product components [Back-end area] ・Design and development of APIs using Ruby on Rails/Python ・Design and development of databases ・Design and development of architecture using AWS environment ・Design and development of batch processing using Python ・Design, development and improvement of functions using natural language processing techniques *Scope of change: development-related work 【Team Structure】 Product Engineering Unit (27 people) Breakdown: 1 VPoE, 3 lead engineers, 24 engineers 【Development Environment】 [Organization] Functional feature-based structure: 1 Product Manager (PdM), 1–2 Product Designers, and 5–7 Engineers.
