Job Description
Key Responsibilities:
Reduction of hallucinations in listing data, token optimization, and personality tuning for different agent types (Broker vs. Lender).
Agent Persona Development: Creating and fine-tuning the "instructions" that govern how the AI behaves (e.g., making the Lender Agent cautious and the Sales Agent persuasive but honest).
Context Window Optimization: Designing prompts that efficiently use Claude’s 200k+ context window to analyze entire portfolios of property listings without losing focus.
Output Structuring: Ensuring Claude always responds in predictable formats (like JSON or XML) so the Fullstack Developer can render that data into UI components like tables or maps.
Hallucination Mitigation: Implementing rigorous "Grounding" techniques within prompts to force the AI to cite specific property data and avoid making up financial figures.
Prompt Red-Teaming: Identifying where the AI might be "tricked" into giving bad real estate advice and building defensive layers into the system prompt.
Key Activities:
A/B testing of prompts, implementing Chain-of-Thought techniques, and monitoring model performance.
Prompt Iteration & Benchmarking: Writing, testing, and scoring dozens of variations of a prompt to find the one that produces the most accurate ROI calculation for an investor.
XML Schema Design: Using Claude-specific XML tags (e.g.,<listing_data>,<financial_analysis>) to organize the information the AI receives and provides.
Collaborative Logic Mapping: Working with the Financial AI Analyst to turn a complex "Waterfall Distribution" formula into a step-by-step reasoning prompt the AI can follow.
Performance Monitoring: Analyzing "failed" AI interactions to determine if the prompt or the data was at fault, then optimizing the instructions accordingly.
Knowledge Base Curation: Selecting the "Best Examples" (Few-Shot samples) of real estate contracts and listings to show the AI exactly how we want it to write.
Academic Skills and Qualifications
Bachelor’s Degree: Linguistics, Computer Science, Philosophy (Logic focus), or Computational Linguistics.
Prompt Engineering Certification: Proven portfolio or certifications specifically in LLM optimization and prompt design.
AI Specialization: Deep understanding of the Transformer architecture and the specific "Constitutional AI" approach used by Anthropic.
Data Literacy: Ability to understand JSON, XML, and basic Python to test how prompts interact with software backends.
Key Skills and Qualifications:
Python, Anthropic Claude API, Advanced Prompt Engineering.
Mastery of Natural Language: An exceptional ability to write clear, unambiguous, and highly structured instructions in English (and Spanish, depending on the market).
Technical Logic: A deep understanding of "Chain-of-Thought" prompting—forcing the AI to "think step-by-step" before providing a final financial answer.
Anthropic Specialist: Specific knowledge of Claude’s "System Prompt" vs "User Prompt" architecture and its unique handling of long-form text.
Analytical Curiosity: The patience to test a prompt 100 times just to change a single word that improves accuracy by 5%.
Cross-Functional Communication: The ability to explain to the UX Designer how a prompt's structure will affect the speed and style of the user interface.
Work Experience:
3+ years in NLP or LLM interaction.
Daily Job Schedule:
The daily job schedule will follow the standard working hours of the company, typically from 9:00 AM to 5:00 PM. However, occasional flexibility may be required to meet project deadlines or collaborate with remote team members.
