• Implement and uphold MVVM architecture patterns and write comprehensive unit and integration tests to keep the codebase clean, testable and maintainable
• Use AI dev tooling as part of your daily workflow to improve productivity across development, testing and documentation, while maintaining full ownership of quality, security and correctness
• Solve problems with new and emerging technologies including distributed databases, real-time syncing, message queues, and distributed transactions
• Interface with and support a myriad of hardware devices while building abstractions around them

• Regular use of AI dev tooling in your daily workflow, with the judgment to verify its output and know when to rely on it
• Willingness and ability to own/manage specific aspects of the development process including implementation, testing, or deployment (CI/CD)
• Exposure to distributed systems and peer-to-peer architecture
• Restaurant tech, retail POS, or any in-store operational system background
