会社概要Company profile They are a startup from the University of Tokyo that develops businesses using big data and generative AI, and they support data utilization and digital transformation, mainly for major companies.
They develop their business by utilizing various alternative data such as credit card data, POS data, and location information data, and by leveraging the experience they have cultivated in building data infrastructure and generative AI.

They have recently been supporting business efficiency with generative AI, building data infrastructure and using big data to support decision-making for new store openings,
and provide support using the latest technology in a wide range of industries and fields.
仕事内容Job description In many DX projects, there are deep gaps between "strategy (drawing the picture)," "implementation (building the system)," and "execution (embedding it into operations)," and quite a few companies are unable to generate a return on investment (ROI). In the use of generative AI in particular, there are many cases where projects advance as far as PoC but stall without being incorporated into actual operations or systems.

The AI + consulting business provides end-to-end support to major financial institutions, from AI adoption to embedding it into operations and improving its operation. In addition to in-house products such as the Finstage series and MCPass, we also utilize external services such as Snowflake, Microsoft Copilot, Claude, and ChatGPT to provide solutions tailored to each client's challenges and system environment.

The FDE is the role that drives these efforts from the technical side. We are looking for people who, building on their experience implementing software and generative AI, want to expand their role into dialogue with clients, requirements definition, and taking technical leadership of projects.

4. Operational improvement and effect measurement after introduction

応募資格Requirement Development experience as a software engineer (2–3 years or more. Any area, such as frontend, backend, or native apps)
