Works with consultants on customer projects to design and implement tailored solution architectures, integrate company products, run PoCs, and connect field insights to product development.
About this role
This full-stack engineering role develops product features that address issues identified by operational teams and customers. The engineer works closely with non-engineering, sales, and business development teams to provide value through agile development.
Responsibilities span frontend, backend, and infrastructure. The products include internal business-support tools, products for clients, and AI-enabled conversational digital humans. The role also involves putting AI into practical business workflows and continuously optimizing those implementations.
Complex business requirements are structured and addressed using domain-driven design. The stated architecture combines Domain-Driven Design, Clean Architecture, and CQRS.
The frontend stack includes Next.js 15 with App Router, TypeScript, shadcn/ui, and Tailwind CSS. The backend uses Hono as an API framework and Prisma ORM. PostgreSQL is used for the database. Infrastructure runs on AWS ECS and is managed with Terraform. GitHub Actions is used for CI/CD.
The position is closely connected to business development rather than being limited to a separate development function. Development incorporates direct feedback from customers and operational teams, and the scope covers full-stack work with the listed technologies and architecture practices. The work location is in Minato-ku, Tokyo, at the Toranomon office address provided in the posting.
