• Design, build, and own Manny features end to end across the agent backend, tools, and UI
• Improve agent behavior, reliability, and answer quality through prompt engineering, tool design, and changes to the agent control flow
• Evolve the agent architecture: ReAct loop, routing and controller logic, multi-node graphs, tool selection, and streaming responses
• Integrate and tune LLMs across providers (Anthropic, OpenAI, Google), balancing quality, latency, and cost, including prompt caching and model selection
• Design and extend Manny's tool surface through the MCP server that connects the agent to Planera's scheduling services
• Build and own the evaluation loop: golden datasets, automated evaluators, snapshot-based replay, and offline and online quality metrics
• Implement observability for agent runs with tracing, metrics, and structured logging, and use it to debug and improve behavior in production
• Ensure safe, sandboxed execution of model-generated code and safe handling of tool side effects and mutations
• Collaborate with product, backend, and frontend to deliver AI features end to end
