About this role

RAKSUL is hiring a Corporate Engineer in its Corporate Technology department, which provides corporate IT to all group employees and builds in-house products and automation for HR, accounting, legal and sales planning. As the group grew, people and organization data and IT foundations became fragmented, and the role reconnects them into a next-generation shared base for about 20 group companies.

The engineer treats internal departments as customers, goes into the field to hear problems and builds a working prototype on the spot in a forward-deployed style. In a small team of one product manager and three engineers using generative AI such as Claude Code and agent tools such as Dify, the work includes moving functions out of a monolith (people and organization master, identity management, ticketing and asset management), adding subsidiary features to identity management, and building automation that links SaaS such as HRMOS, freee and Microsoft 365 with BigQuery.

Applicants need hands-on experience building or improving things with AI, such as AI coding, LLM agents or automation, plus some experience developing or improving web or internal systems; attitude matters more than years. User-first thinking and native-level Japanese are required.
