App Growth Specialist

About this role

This position is responsible for growth initiatives involving advertising and campaign offers within Resichalle, a savings app that supports consumers’ shopping through receipt purchases for eligible products. The service also provides manufacturers and retailers with a platform for addressing marketing issues using purchasing data.

The role works with sales to analyze performance for each assigned offer. It involves tracking progress against short-term targets, breaking down the user journey to identify bottlenecks, and deciding which measures should be taken next. The person in this role plans and directs the implementation of in-app pop-ups, banners, push notifications, and campaigns. They develop hypotheses for promotional wording and creative assets, conduct A/B tests, and apply the results to subsequent offers.

Responsibilities also include designing and improving operating procedures for delivery settings, submission and setup, and numerical aggregation. Generative AI tools may be used to improve these workflows. The posting identifies Claude and Codex as AI tools used in the work, with AI also supporting analysis, measure planning, and implementation support.

After joining, the successful candidate initially learns the business alongside existing members. Once familiar with the work, they are expected to take responsibility for assigned offers as a unit. The role carries responsibility for numerical targets and discretion over the methods used to achieve them.

Measures are not limited by a fixed daily number, and the posting describes a process in which testing is not stopped because of workload or approval procedures. Results generally appear in the numbers from the following day to several days later. Offer conversion numbers directly affect business revenue, allowing the effect of improvements to be evaluated through business results. Because the area does not follow a fixed operating model, the person is expected to develop working methods that may become team standards when effective.

The initial focus is on Resichalle offers. Depending on results and interests, the role may expand across services including Offerwall and Usapo, or into broader marketing areas such as ad-network operations and MAU growth initiatives. Future responsibilities are expected to include both measure design and numerical accountability, as well as helping determine the direction of the team.

The role is part of a small team working with specialists from different areas. The posting describes a flat environment where members exchange opinions regardless of title, quick decision-making from planning to execution, and active use of current AI tools. Main tools include Braze and Lightdash for CRM and analysis, Claude and Codex for AI use, and Slack and Notion for communication. The listed workplace is in Minato, Tokyo.
