About the Job

Requirements

  • Have at least 5 years of hands-on UX research experience for digital products in an environment with a UX research organization, and have driven product improvements through that research.

  • Be able to logically structure complex situations or concepts, identify meaningful insights, and connect them to action.
  • Submit a portfolio showing specific professional projects in which you personally designed and conducted research to improve user experience; research-only and side projects are not suitable.

Responsibilities

  • Establish Toss Incomeโ€™s research foundations and operating practices from scratch, including research operations, a recruiting pool, and insight archiving, so the team develops a shared understanding of users.
  • Design and conduct research with individual business owners and users of the comprehensive income tax refund service, including visiting offline businesses to interview and observe owners in context.
  • Partner with the silo responsible for both B2C and B2B, defining and proposing needed research proactively rather than only fulfilling requests.
  • Identify business opportunities through user context, validate the value the team should prioritize qualitatively, and ensure findings inform product direction and priorities.
  • Surface problems from usersโ€™ voices, pose questions to the team, define problems to solve, and drive the resulting action items.
  • Lead foundational research to improve the experience of individual business owners over the long term, alongside short-term projects.

Desired Qualifications

  • Interest in the gap between business goals and users, and willingness to engage actively with business contexts.
