  • Design & Optimization: Develop complex prompt engineering strategies to maximize the performance of LLMs in various business applications.
  • Model Fine-Tuning: Collaborate with the ML team to fine-tune pre-trained models on proprietary datasets to improve accuracy and relevance.
  • Evaluation & Testing: Create rigorous testing protocols and evaluation metrics to assess the quality of AI outputs against human benchmarks.
  • Documentation: Maintain comprehensive documentation of prompt libraries, techniques, and best practices for the engineering team.
  • Cross-Functional Collaboration: Partner with UX designers and product managers to integrate AI features seamlessly into user interfaces.
  • Security & Ethics: Ensure all prompts adhere to ethical guidelines and data privacy regulations to prevent bias and misuse.

Qualifications

  • Experience: 3+ years of experience in copywriting, content strategy, or technical writing, with a strong portfolio demonstrating creative problem-solving.
  • Technical Skills: Familiarity with Machine Learning concepts, API integration, and tools like Python or LangChain.
  • LLM Proficiency: Deep understanding of how Large Language Models work, including context windows, tokenization, and temperature parameters.
  • Communication: Exceptional verbal and written communication skills with the ability to translate complex technical concepts into clear instructions.
  • Adaptability: Ability to experiment, iterate quickly, and pivot strategies based on model performance data.
  • Education: Bachelor's degree in English, Computer Science, Linguistics, or a related field is preferred.
