Senior Full-stack Developer (AI Agent)

We're building AI agents that autonomously resolve customer support tickets for e-commerce businesses end-to-end. Our agents cancel orders, issue refunds, check inventory, communicate with suppliers, and continuously improve over time. To make this scalable, we're building an AI Manager — a higher-level agent that trains, monitors, and optimizes Support Agents with minimal human input. Our goal is an AI-run support team, where managing AI feels like managing a human teammate, not writing prompts.

• Lead the technical design of complex, cross-cutting features and systems
• Make architectural decisions with long-term impact, balancing speed, scalability, and maintainability
• Proactively identify systemic risks, bottlenecks, and failure modes, especially in AI-driven workflows
• Build and evolve AI-driven systems that manage, evaluate, and improve autonomous agents
• Develop AI-native, self-serve workflows for customers to configure and improve their agents without human-heavy setup
• Design and implement scalable backend services using Python and FastAPI
