Mobile Application Engineer

• Own mobile product end to end - from customer calls and spec to build and ship, across iOS and Android.
• Sit with users in the field to understand how they actually work on-site and on-the-go.
• Build production-grade cross-platform apps in React Native + TypeScript; drop into native (Swift/Kotlin) when needed - camera, sensors, background tasks, secure storage.
• Maintain existing apps and build new ones; own App Store / Google Play release and update cycles.
• Design for unreliable connectivity: local persistence, offline capture, conflict resolution, reliable sync.
• Translate messy real-world field processes into clear, intuitive mobile UX.
• Integrate AI features (LLMs, agents, model-backed APIs, on-device/voice) into mobile workflows where they help.

• Exceptional engineering pedigree (non-negotiable) - standout work at a top company, AI lab, elite trading firm, or fast-scaling startup; equally open to engineers who’ve built and shipped apps at strong startups. A famous logo isn’t required, but it helps.
• Strong TypeScript and React Native (or equivalent cross-platform framework) - RN + TS is the preference, but exceptional engineers from other mobile stacks will be considered.
• Solid native mobile fundamentals across iOS and Android (both matter at launch), and comfortable reaching into native code (Swift/Kotlin) when the RN layer isn’t enough.
• Comfortable building and consuming backend services that support complex mobile workflows (Python a plus).
• Reasons about complex workflows and offline-first constraints, not just CRUD.
• Comfortable talking directly with customers, including non-technical domain experts, in the field.
