• Build and deliver new features and bug fixes with a strong focus on reliability, performance, and user satisfaction.
• Design and develop reusable tools, modules, and integrations that enable new AI capabilities across different model types and sizes.
• Build and maintain AI agent harnesses, including tool calling, agent loops, context management, and structured outputs.
• Develop evaluation frameworks and testing infrastructure for AI systems with non-deterministic behavior.
• Implement and evolve peer-to-peer technology to support local AI and distributed use cases.
• Maintain a high-quality codebase through consistent coding standards, code reviews, modular architecture, and automated testing.
• Design systems that can reliably handle failures such as network partitions, model errors, timeouts, and retries.
• Develop and maintain reusable npm modules and shared software components.
• Experiment with new technologies and approaches to continuously expand AI and P2P capabilities.
• Collaborate effectively with a globally distributed engineering team while communicating technical ideas clearly.

• 5+ years of experience building and maintaining production software.
• Strong proficiency in JavaScript and TypeScript, including experience modeling complex state across synchronization protocols, agent loops, or similar systems.
• Strong ability to write modular, maintainable, and reusable code.
