Its products and research leverage machine learning, UX research, and strong security practices to help individuals find jobs, improve career outcomes, and navigate career transitions globally.

📋 Description

• Design, prototype, and iterate complex system prompts, few-shot exemplars, and chain-of-thought structures for consumer AI experiences, including Resume Adaptation, Personalization, and Real-time Feedback. • Partner with LLM/Machine Learning Engineers, Product Managers, and UX Designers to translate product requirements into technical prompt specifications, optimizing for latency and API costs. • Architect evaluation frameworks - automated, heuristic, and human-in-the-loop - to benchmark, test, and guardrail LLM outputs against hallucination, bias, and tone drift. • Develop standardized prompt frameworks, version-control workflows, and operational playbooks to help distributed product teams leverage AI safely and efficiently. • Monitor the evolving GenAI landscape - OSS models, new architectures, and prompt techniques - to continuously improve product performance and model throughput.

🎯 Requirements

• 5+ years of professional experience working closely with language technologies, computational linguistics, or software product development. • 2+ years of hands-on experience shipping LLM-backed features to production for consumer applications, spanning the full prompt development lifecycle and automated evaluation (eval) prompts. • Mastery of advanced prompt engineering techniques: few-shot, chain-of-thought, ReAct, and prompt chaining. • Deep familiarity with LLM evaluation tools and frameworks such as RAGAS, LangSmith, TruLens, or custom heuristic testing. • Proven ability to manage complex prompt deployment pipelines in a fast-paced, continuous integration environment.
