Prompt Engineer: LLM Migration & Optimization
Welo Data
United States. Remote Part-Time Are you an expert at navigating the complex logic of Large Language Models? Welo Data is seeking a technical Prompt Engineer to lead the end-to-end migration of template workflows into high-performance LLM autoraters. This isn't just about writing prompts—it’s about engineering a technical bridge. You will use advanced APG/APO tools and manual refinement to ensure our automated systems meet (and exceed) human accuracy baselines. The Mission: Architecting the Future of Rating Technical Migration: Take ownership of the workflow for transitioning templates to LLM autoraters. Optimization Leadership: Run and supervise Automated Prompt Optimization (APO) tools, identifying where logic plateaus and providing the manual "spark" to overcome deadlocks. Metrics-Driven Accuracy: Continuously measure quality against gold data, calculating critical performance metrics like precision, recall, and $F_1$ scores. Edge-Case Engineering: Solve complex scenarios by designing manual prompts that handle anti-patterns and broken logic in legacy architectures. Project Details Schedule: Part-Time (Flexible hours within project milestones) Location: 100% Remote (Must be based in the United States) Employment Type: Freelance / Independent Contractor Who We Are Looking For Linguistic & AI Mastery: 2+ years of experience as a Prompt Engineer. You must be comfortable tuning LLMs for structured outputs and complex classification tasks. Academic Background: BS, MS, or PhD in Computer Science, Data Science, Computational Linguistics, or a related analytical field. Technical Agility: Fast learner capable of mastering proprietary internal tools and interfaces (like the Goose API) with minimal supervision. Data Fluency: Strong ability to identify error patterns and use SQL or data analytics tools to analyze model performance. Preferred Skills Familiarity with shadowbot disagreement tracking between humans and LLMs. Hands-on experience with Chain-of-Thought (CoT) and few-shot learning. Proven ability to draft high-level Launch Certification Documentation. #J-18808-Ljbffr Welo Data
