Requirements

  • Native-level Japanese proficiency and experience in UX writing for Japanese users.
  • Ability to simplify difficult specialist terminology without losing accuracy.

  • Rework complex financial terminology and investment materials into clear, accessible, user-centered language consistent with Toss Securities’ voice and tone.

  • Work closely with user research, product designers, and developers to improve writing quality and consistency across the service.
  • Define the Japanese service’s voice and tone based on evidence of where users respond and hesitate.
  • Strengthen the product experience and contribute to Toss Securities’ business results through strategic marketing copy.

About the Company

Toss

Fintech super-app for payments and banking

Toss is a South Korean financial services platform that started as a peer-to-peer money transfer service and has grown into a digital 'super app' for personal finance. Its products are accessed through one mobile interface that unifies bank accounts, credit cards, loans, investments, and other financial services, including its own Toss Bank and Toss Securities. It differentiates itself by offering a broad, integrated ecosystem—combining digital banking, asset management, and brokerage services under one roof and running its own banking and securities units. Its goal is to become the leading consumer finance platform in South Korea while expanding its user base globally.
