About this role

Dwango's education business, which runs the systems behind Japan's largest online high schools (N, S and R High Schools, with over 30,000 active students), is hiring a School Platform Development Engineer. The student count grows by about 10,000 a year.

The engineer develops and operates the academic administration system used by students, parents, teachers, mentors and office staff, including the N Lobby portal. It manages course registration, exam grading, records, promotion and graduation, links with the ZEN Study learning system and supports online admission. Work covers detailed design, implementation, testing, release, operation and defect investigation, in TypeScript, Java and Next.js on AWS.

Applicants need three or more years each of statically typed language development, web application development and B2B business-system development, the ability to take requirements through to design, ORM experience with awareness of inefficient queries such as N+1, and pull-request-based development. React, TypeScript, schema design, PostgreSQL tuning and AWS operations experience are preferred.
