⭐️ Key Responsibilities

• Design and Optimization of Prompts: Create, test, and continuously refine complex prompt systems for voice bots, including:
• Conversational Flows: Designing multi-turn dialogue scenarios that feel natural and intuitive for the user.
• Role-Playing Scenarios: Crafting precise persona and role-based prompts to ensure the bot adheres to its designated character (e.g., customer support agent, sales representative).
• Data Extraction: Developing prompts to accurately identify and extract key information from user speech.
• Dynamic Prompt Management: Implement and manage logic for the dynamic adaptation of prompts in real-time based on conversation context, user sentiment, and specific variables.
• Function Calling & Variable Integration: Design and integrate robust systems using function calling and variables to fetch external data, execute actions, and personalize interactions within the conversation flow.
• RAG Implementation: Utilize and optimize Retrieval-Augmented Generation (RAG) systems to provide the bot with access to specific, up-to-date knowledge bases. Specifically, calling functions and existing RAG tools to enrich agent responses with up to date live data, and extracting key data from the conversation.
• Testing and Quality Assurance: Rigorously test and evaluate LLM responses against criteria such as accuracy, relevance, completeness, safety, and brand tone alignment.
• Analysis and Iteration: Analyze problematic interactions, user feedback, and performance metrics to identify root causes and implement prompt corrections and improvements.
• Prompt is generally expected to be written in English.

⭐️ Required Qualifications & Skills

• 2+ years of hands-on experience working with Large Language Models (LLMs), preferably with commercial models like GPT-4, Claude, or similar.
• Proven experience (1+ years) in prompt engineering, specifically for developing and testing robust, multi-turn conversational agents (chatbots or voice bots).
• Strong skills in testing prompts for functionality, reliability, and resilience to varied user inputs and re-generations.
• Solid understanding and practical experience with LLM function calling to create dynamic, action-oriented bots.
• Proficiency in working with variables and context management to maintain coherent and personalized conversations.
• Basic understanding of programming (e.g., Python, JavaScript), working with APIs, and integrating with development tools.
• Strong analytical skills to debug suboptimal LLM outputs and systematically improve prompt design.
• Understanding of and experience with RAG (Retrieval-Augmented Generation) architecture.

⭐️ What Will Make You a Strong Candidate (Preferred Qualifications)

• Experience with voice-specific platforms (e.g., Google Gemini, Ultravox, Amazon Lex, 11labs) or speech-to-text/text-to-speech technologies.
• Familiarity with the cultural nuances, communication styles, and linguistic diversity of the Latin American market (e.g., understanding differences between Mexican, Colombian, and Argentine Spanish).
• Knowledge of Portuguese is a significant plus for the Brazilian market.
• A portfolio or examples of previous conversational AI projects you have contributed to.
