About this role

JAPAN AI, a Geniee group company, is hiring a young Full Stack Engineer for its core team that builds the next-generation core system, the enterprise brain, on its JAPAN AI STUDIO platform. The core team has seven people and is growing toward thirty; this opening adds a slot for early-career engineers to be trained into central staff.

The engineer works with senior engineers in customers' workplaces, learning how a company's SaaS tools fit together and building workflows with AI, such as request approval, resource allocation and prospect discovery, plus API integrations with tools like Salesforce, SmartHR and kintone. The role grows in phases: implementing workflows and proofs of concept designed by seniors, then designing and implementing small workflows alone, then leading mid-sized features and joining technology choices.

Applicants need at least one year of professional software engineering, implementation in Python or TypeScript, a full-stack orientation (a main focus on back end or front end is fine if willing to learn the other), experience or strong interest in LLM and generative AI applications, and native-level Japanese. Cloud and agent-framework experience are preferred.
