Job Title: AI Prompt Strategy Lead – Generative Interfaces
Location: San Francisco, CA (Hybrid or Onsite Preferred)
Industry: Generative AI, NLP, Applied Research
Job Type: Full-Time
About the Opportunity:
We are seeking a visionary AI Prompt Strategy Lead to spearhead the next wave of human-AI interaction. This role will drive the prompt architecture and design behind cutting-edge GenAI applications, working on everything from retrieval-augmented generation (RAG) systems to creative AI copilots. Join a stealth-mode innovator shaping the evolution of how language models power real-world solutions—from intuitive chat tools to intelligent enterprise agents.
Key Responsibilities:
• Design, prototype, and refine prompt strategies for large language models (LLMs), such as GPT-4, Claude, and LLaMA
• Build and iterate on advanced RAG pipelines utilizing vector databases and scalable architecture
• Engineer model behavior through techniques like system prompt tuning, few-shot prompting, and chaining
• Collaborate cross-functionally with engineering and product teams to integrate LLMs into production-ready tools and user interfaces
• Implement robust evaluation frameworks to measure model output quality, safety, and alignment
What You Bring:
• 2+ years of hands-on experience with LLMs in a research, product, or deployment setting
• Fluency in using LLM APIs and frameworks from OpenAI, Anthropic, Cohere, or open-source equivalents
• Proficiency in constructing and optimizing RAG systems with tools like Pinecone, Weaviate, or FAISS
• Knowledge of prompt engineering tactics, token efficiency, and fine-tuning behaviors
• Experience with orchestration tools like LangChain, LlamaIndex, or equivalent frameworks
Preferred Qualifications:
• Academic or applied background in linguistics, NLP, or HCI
• Exposure to fine-tuning methods (e.g., LoRA, QLoRA) or training from instruction datasets
• Experience building autonomous agents or copilots for internal or end-user environments
• Familiarity with prompt evaluation tools such as Promptfoo or TruLens
Total Rewards:
• Base compensation from $150,000 to $210,000
• Generous equity offering
• Comprehensive health and wellness benefits
Why Apply:
• Play a core role in redefining the interaction between humans and machines
• Join a tight-knit team of top-tier engineers and researchers in the epicenter of the AI transformation
• See your work impact real products and improve the future of how AI supports daily work and life
