Requirements

• 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.
