History of delivering complex features within a software team to drive business outcomes
Experience breaking down ambiguous operational requirements into concrete technical plans
Exposure to integrating with third-party platforms and managing the data contracts between systems
Familiarity with React Native is a plus — occasional contribution to mobile promotional surfaces may be required

Strong React experience — deep understanding of component lifecycle, hooks, performance optimization, and patterns for data-heavy, form-heavy internal applications
Experience with RTK Query, React Query, or similar data-fetching and caching layers for complex admin UIs
Experience building and consuming REST or GraphQL APIs; comfort reasoning about backend data models even if your primary focus is the frontend
Familiarity with Braze or similar CRM/messaging platforms — understanding how promotions, segments, and campaigns are structured and delivered
Experience with state management solutions suited to complex, multi-step workflows (form state, async data, optimistic updates)

Familiarity with CI/CD pipelines, containerized local dev environments, and web deployment workflows
Working knowledge of React Native — enough to contribute to mobile-facing promotional surfaces when needed
Autonomous — you can take an ambiguous operational problem and drive it to a well-defined technical solution
Comfortable working directly with internal stakeholders to validate requirements and surface tradeoffs
