Tokyo Build+ (formerly Wahl+Case)

Senior Software Engineer (iOS/Android) – Drive Cross-Platform Innovation

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 Role

Reporting 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 Role

  • Lead 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.

    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)
