Mobile Engineer

What Do We Do?

Triple Whale is the AI operating system built for modern ecommmerce. We help you see what's actually working in your business, what's not, and what to do next. Then we take action for you — pausing the underperforming ad, generating the next batch of creative, flagging the inventory risk before it bites.

We pull every signal in your business into one place, and put it on the most trusted measurement foundation in the industry. And on top of that, we give you the most actionable AI in commerce — Moby 2 — letting you tap any LLM you want, grounded in the full context of your business. Moby 2 doesn't just surface insights, it executes decisions for you, with automations that make the rest of your stack smarter.

The result: more than 60,000 brands like Pressed Juicery, OUAI, and True Classic turn mountains of complex data into actions that actually grow profit, at a speed and scale that is not humanly possible.

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 systems.
• Comfort working and collaborating closely with designers.
• Experience with data visualization or graphics rendering on mobile.
• Familiarity with mobile CI/CD pipelines and release automation.
• Comfortable using AI-assisted development tools as part of daily workflow.

Why You'll Love This Role:

You'll be building a mobile app from the ground up, working closely with the lead engineer who architected the foundation. You'll contribute to real features end-to-end, from data streaming to pixel-perfect UI, with direct impact on how merchants interact with Triple Whale on mobile. You'll participate in meaningful architecture decisions, work with a modern stack and automated quality tooling, and ship quickly in a fast-moving environment that doesn't compromise on quality.
