  • Integration: Work closely with software engineers to seamlessly integrate prompt logic into scalable production applications.
  • Documentation: Maintain detailed libraries of effective prompts and develop internal guidelines for AI usage across the organization.
  • Innovation: Experiment with emerging AI architectures (e.g., GPT-4, Claude, Llama) to find novel applications for our business needs.

Qualifications

  • Experience: Proven track record of using and optimizing Large Language Models (LLMs) such as GPT-4, Claude, or PaLM.
  • Technical Skills: Strong proficiency in Python and RESTful APIs.
  • Education: Bachelor’s degree in Computer Science, Linguistics, English, or a related technical field.
  • Communication: Exceptional command of the English language, including grammar, nuance, and tone.
