Welo Data is seeking a Lead Prompt Engineer to spearhead the technical migration of template architectures into state-of-the-art LLM autoraters. This is a high-stakes leadership role.

  • Advanced Optimization: Direct the use of APG and APO tools, providing the high-level intervention needed when automated systems reach plateaus.
  • Launch Certification: Take final responsibility for accuracy metrics, running prompt versions against gold data to verify $F_1$ scores, precision, and recall.
  • Edge-Case Resolution: Architect manual prompt strategies to solve the most difficult "anti-patterns" in legacy architectures.

  • Location: 100% Remote (Must be based in the United States)
  • Employment Type: Freelance / Independent Contractor
  • Duration: Long-term technical migration project

  • Technical Agility: Expert-level ability to master proprietary tools and enterprise-grade interfaces like the Goose API.
  • Leadership Excellence: A natural mentor with the verbal and written communication skills required to justify technical launches to stakeholders.
