About Mantra
We're the creators of Mantra Engine, a cloud-based manga localization platform for enterprise clients. In addition to our SaaS platform, we also offer end-to-end localization services for publishers, manga distributors, and entertainment companies.
Examples of our translation initiatives include:
- Simultaneous Japanese-English serialization support for The Ancient Magus’ Bride using Mantra Engine
- Multilingual same-day manga distribution support for Shueisha titles
While manga and comics are currently our core focus, we are actively expanding into broader entertainment domains including video games, light novels, and video content.
As demand for our localization services continues to grow rapidly, we are seeking a Localization QA Specialist to help strengthen our localization pipeline and ensure high-quality localized content across projects.

- Organize feedback and provide actionable guidance to translators and reviewers
- Evaluate translation quality and provide actionable feedback to improve localization outcomes across projects
- Propose workflow improvements from a QA and quality optimization perspective
Note: Some project coordination responsibilities may be included, but the primary focus of this role is quality ownership and assurance.
