About this role
This role handles system planning and DX for in-house systems supporting Japan’s electricity markets. It translates changing rules from JEPX, EPRX and OCCTO into specifications for settlement and other business systems.
It reads regulations, guides and API specifications, identifies system rules and terms, and fixes data units, relationships, states and calculation logic with engineers. It writes glossaries, domain documents and API requirements in GitHub pull requests, defines acceptance criteria in Azure DevOps, reviews ER diagrams, API specifications and state-transition diagrams, and creates screen mockups with Claude Code, Cursor or similar AI coding tools. It also defines requirements for automating manual internal work.
Applicants must have experience interpreting unstructured regulations, laws or industry standards and converting them into system specifications. They must determine specifications with engineers at the level of data units, relationships and states, use AI coding tools as standard work tools, and independently decide undefined matters and move them forward.
