Mobile Engineer

What Do We Do? Triple Whale is the complete intelligence platform for ecommerce, helping brands stop guessing and start knowing what’s actually driving growth, what’s wasting money, and what to do next — with total confidence. By pulling all of a company’s data into one place, delivering measurement tools teams can actually trust, and applying the smartest AI in the industry, Triple Whale turns fragmented data into clear insights and actionable recommendations. That intelligence can then be put to work through AI agents and automations that generate creative assets, take action across marketing channels, and make every tool in their stack smarter and more effective. More than 60,000 ecommerce brands including Pressed Juicery, OUAI, and True Classic trust Triple Whale to grow faster and drive revenue with fewer resources by uncovering opportunities and acting on them at a scale that would be impossible manually. Why Triple Whale Needs You: Triple Whale is launching its first native mobile app, and we need engineers who can build it right from the ground up. As our merchants increasingly rely on mobile to monitor their business in real time, we need someone who can think in systems, build performant and resilient mobile foundations, and ensure the app delivers a native-quality experience even under poor network conditions. Your experience building production mobile apps will directly impact how quickly we can ship, how reliably merchants can access their data on the go, and how confidently we can expand the mobile platform as it grows. What You'll Do: Build and maintain the Triple Whale React Native mobile app, with a strong focus on performance, offline resilience, and native-quality UX. Build and maintain mobile UI components by translating Figma designs into production code using a design token system, collaborating with design and product teams to ensure visual parity with web. Build data-driven screens with real-time streaming data, charts, and complex list rendering optimized for mobile constraints. Participate in designing the reactive data layer - state management patterns, server-state caching, and offline-first strategies that work reliably across network conditions. Participate in mobile infrastructure work: navigation architecture, gesture-driven UI, native module integration, and authentication flows. Contribute to the technical health of the mobile codebase by enforcing architecture standards, optimizing rendering performance, managing bundle size, and making informed build and tooling decisions. Leverage AI tooling to assist with development workflows - code generation, refactoring, design-to-code alignment - while applying strong engineering judgment to review and productionize results. What You'll Bring: Ability to work from our Jerusalem office (located in the Central Bus Station next to the train) 2 times a week (Monday & Wednesday) is required High level of English (spoken and written) 5+ years of hands-on experience building production React Native apps with strong TypeScript skills. Experience with native build tooling and deploying apps to both the App Store and Google Play, including release workflows, signing, review processes, and OTA updates. Ability to assess mobile architecture tradeoffs - native vs. JS solutions, listeners vs. polling, local cache vs. server state - with a deep understanding of the performance, battery, and offline implications. Solid experience with reactive state management - structuring stores, derived state, side effects, and subscriptions to minimize unnecessary re-renders and handle real-time streaming data efficiently. Strong problem-solving skills and effective cross-team collaboration. Comfortable working under pressure with tight deadlines, with high availability and responsiveness Bonus Points If You Bring Experience with offline-first caching strategies and local persistence in mobile apps. Experience building or contributing to shared component libraries or design token
