The posting describes close collaboration with management, the business owner, development teams, and other internal and external stakeholders. Migakun began service in 2024 and is currently accelerating productization. The role may also use assets from the Akerun business, including brand awareness, its customer base, and connections to IoT technology; involvement in the Akerun business strategy office or other new businesses may be possible in the medium to long term.
