You'll contribute across the stack, with a strong focus on TypeScript, modern frontend architecture, and clean system interfaces. While we also use React Native for our app, the primary focus is TypeScript-based development, not mobile specialization.
This is a hands-on builder role in a fast-moving startup environment.

 * Contribute to our React Native app where needed.
 * Implement clean, maintainable UI logic and state management.

Backend & Integration

 * Work with APIs and backend services to integrate data and features.
 * Ensure reliable data flows between frontend, backend, and AI systems.
 * Improve application performance and robustness.

Code Quality & Speed

 * Write clear, well-structured, and testable TypeScript code.
 * Help keep the codebase clean as features evolve.
 * Move fast without breaking things unnecessarily.

Cross-Functional Collaboration

 * Work closely with Product, AI, and Engineering teams.
 * Translate product requirements into pragmatic technical solutions.
 * Actively contribute to technical discussions and decisions

Bonus: Infrastructure Awareness

 * Support cloud-related tasks when needed (CI/CD, deployments, monitoring).
 * Help improve system reliability and developer experience.
