• Build full-stack features that combine intuitive interfaces with intelligent backend logic

• Design and build the agent framework, including context engineering and agentic workflows

• Own significant product areas end-to-end and help shape the development roadmap

• Shape and improve AI-native product delivery processes as the team scales
