Tokyo | Flexible Remote | ¥8M–¥13M
Our client, a fast-growing Japanese tech company, is entering a bold new phase of growth, expanding from education into enterprise and global markets.
They are now seeking an experienced Senior Software Engineer (iOS/Android) to play a pivotal role in unifying their technology platform and shaping the next-generation mobile experience.
About the RoleReporting directly to the VPoE, you'll lead the transition from three separate codebases (iOS, Android, Web) to a "build once, deploy everywhere" architecture.
This is a core, high-impact position where you'll influence product direction, drive platform integration, and set technical standards across the organization.
Why You'll Love This RoleLead a company-wide innovation project: spearhead the unification of mobile, web, and backend stacks.
Work closely with senior leadership, including executives from top-tier global companies.
Gain rare full-stack exposure across iOS, Android, Web (React/TypeScript), and backend (Scala, C++).
Join a company on track for IPO, currently 100+ employees and expanding fast.
Collaborative, humble, and impact-driven culture — where good ideas win, not titles.
What You'll Bring
3+ years of native mobile development experience (Swift or Kotlin)
Strong understanding of mobile architecture and cross-functional collaboration
Flutter experience is a big plus
Business-level Japanese (written and spoken)
If you're excited to lead a technical transformation and make an impact beyond just code, this is the perfect time to join.
Apply now to explore this opportunity with one of Japan's most forward-thinking tech companies.
