You'll own the prompting layer for Abba Baba's agent behaviors — designing, iterating, and systematically optimizing prompts that control how agents negotiate, discover, QC-check, and settle transactions. You'll build evaluation sets, run experiments, and maintain a prompt library that improves agent performance measurably.

Requirements

  • prompt engineering
  • LLM evaluation
  • Python
  • experimental design
  • Claude / GPT / Gemini API
  • behavioral analysis
  • documentation

Responsibilities

  • Design and iterate prompts for core agent behaviors (negotiation, discovery, QC, settlement)
  • Build evaluation datasets that measure prompt performance against target behaviors
  • Run systematic A/B experiments on prompt variations with statistically valid sample sizes
  • Maintain a versioned prompt library with performance history for each variant
  • Identify prompt failure modes and design mitigations before production deployment
  • Document prompting patterns and anti-patterns for the engineering team
