Mindex is looking for a Senior AI Conversation Engineer to design, architect, and implement robust conversational AI systems that drive real business value. You will work remotely to define conversation flows, optimize generative models, and integrate solutions across enterprise systems.
What You'll Do
- Define conversation flows and dialogue architectures to support multi-turn, context-aware, natural dialogs.
- Develop, write, and optimize prompts to guide large-language models (LLMs) or other generative models toward accurate, context-appropriate, safe outputs.
- Fine-tune and/or adjust models (when applicable), including prompt tuning, fine-tuning, or parameter optimization, to align model behavior with product and user goals.
- Integrate conversational AI with existing backend systems via APIs and data pipelines; ensure seamless data flow, context handling, and retrieval when needed.
- Iterate on conversation design through testing: run A/B tests, user simulations, evaluate model outputs (with both automated metrics and human review), debug edge cases, and improve performance over time.
- Collaborate closely with product managers, UX / conversation designers, data engineers, and other stakeholders to define requirements, ensure ethical and safe model behavior, and deliver polished user experiences.
What We're Looking For
- 5+ years of experience in software engineering with a strong focus on Python development and strong problem-solving skills.
- Demonstrated experience in conversation architecture / design: defining dialogue flows, state/context management, branching logic, user experience considerations in conversational UI.
- Deep expertise in prompt engineering: writing, testing, and refining prompts to guide large language or generative models toward desired behavior.
- Experience with model tuning (prompt tuning, fine-tuning, hyperparameter adjustment) or otherwise optimizing model outputs to meet quality, safety, and reliability standards.
- Practical experience with at least one conversation / agent platform (e.g., Dialogflow preferred; or other chatbot/voice-bot platforms / agent frameworks). Ability to build, deploy, and maintain agents on such platforms.
- Experience with API integration; connecting the conversational agent to backend services, databases, or external APIs.
- Solid conversation design experience; understanding of user-centered design, usability, natural language understanding / generation, user experience (UX) considerations, tone and style, context management, fallback and error handling.
- Strong communication skills, ability to collaborate across disciplines (product, design, engineering, data), and translate technical AI capabilities into user-facing solutions.
- Curiosity about latest developments in AI / NLP / LLMs, willingness to experiment, learn, and refine prompts / models / flows continually.
