Key Responsibilities

  • •Own production issues end to end: trace, reproduce, fix, or provide clean reproduction handoff across APIs/integrations, customer-side JavaScript, agent behavior, and data.
  • •Debug agents and prompts by diagnosing whether misfires come from prompts, knowledge base, config, or model; fix prompt/setup for real traffic.
  • •Build durable solutions so problems don’t happen twice by creating runbooks/tools and improving the system to catch the next occurrence.
  • •Close the loop to Product by surfacing recurring patterns from real customer incidents and driving measurable product improvements.

Key Requirements

  • •Solve production problems end to end, distinguishing customer-side causes from product bugs using logs and symptoms.
  • •Debug and iterate on LLM workflows—prompts, knowledge bases, intent classification, retrieval—and rewrite prompts when misfires occur.
  • •Read and reason through code in the core stack, including Node.js, TypeScript, React, and Express; trace browser-side JavaScript and debug backend behavior.
  • •Write diagnostic SQL against PostgreSQL and navigate backend services without needing others for basic tracing.
  • •Build automation/leverage AI coding tools (e.g., Claude Code) to script queries, clean datasets, and accelerate fixes across a growing codebase.
