Project Overview

We are partnering with a pioneering client at the forefront of immersive learning and AI-powered simulations. Their platform enables professionals to practice and master complex interpersonal skills in high-stakes environments using cutting-edge technology that blends Large Language Models (LLMs), speech recognition, natural language understanding, computer vision, and real-time voice synthesis.

What makes this project unique is its combination of human-in-the-loop orchestration with advanced multi-modal AI systems—bringing together live interactions, avatar control, and scalable LLM infrastructure to deliver incredibly lifelike and impactful training experiences. The solution goes far beyond simple chatbot interfaces or single-modal agents.

This is a mission-driven environment backed by research in learning science, psychology, and AI. The goal is to scale this system into a production-grade platform that consistently delivers predictable, stable, and low-latency GenAI performance. If you’re passionate about building enterprise-level LLM infrastructure, working across complex AI systems, and helping shape the future of human-AI interaction—this is a rare and high-impact opportunity.

Role Overview

We are working with a client who needs a strong Prompt Engineer with a deep understanding of LLM (Large Language Model) systems, structured prompt design, and simulation-driven learning environments. This role requires a unique blend of product thinking, linguistic strategy, and experience with AI systems in production. You’ll collaborate cross-functionally with simulation designers, AI engineers, and learning architects to create highly structured, effective prompts for real-world learning scenarios.

***This position is fully remote for candidates based in Colombia, Costa Rica, Mexico, Uruguay, El Salvador, or Peru.

Key Responsibilities

• Design, structure, and refine prompts for complex LLM production environments.
• Implement and manage retrieval-augmented generation (RAG) pipelines using JSON-based structured outputs.
• Develop and maintain evaluation rubrics and prompt testing datasets to measure LLM output quality and alignment.
• Translate abstract learning objectives and human-to-human interaction scenarios into effective prompt-driven AI behavior.
• Act as a strategic liaison between creative simulation teams and technical AI engineers, helping ensure narrative fidelity and technical precision.
• Guide the iterative prompt development process from ideation through implementation, grounded in psychological and communication-based rubrics.
• Contribute to the evolution of prompt engineering processes, tools, and best practices for scalable, production-level deployment.

What You Bring

• 1–3+ years of experience in AI/ML or product-related roles, with direct experience working on LLM systems.
• Demonstrated expertise designing prompts in production-grade LLM environments (e.g., OpenAI, Claude, etc.).
• Strong understanding of RAG architecture, evaluation databases, and structured output formats such as JSON.
• Background in linguistics, psychology, learning design, or communication modeling is a strong plus.
• Experience bridging creative and technical domains — able to work fluently with both instructional designers and engineers.
• Ability to work in ambiguity, rapidly prototype, and refine based on prompt performance data.
• Familiarity with learning experience platforms, human behavior modeling, or communication skill simulations is a bonus.

Nice to Have

• Experience working in simulation platforms, education tech, or virtual learning environments.
• Exposure to psychological rubric design and scenario-based learning journeys.
• Prior collaboration with voice actors, artists, or simulation scriptwriters.

Interview Process

The process is designed to be thoughtful, efficient, and focused on both technical ability and team fit.

1. 30-minute on-demand HireVue screening, where you'll respond to situational and behavioral questions to help us understand your ownership mindset, adaptability, and approach to collaboration.
2. 10-minute virtual Q&A session with our recruiter to clarify the role and answer any questions you may have. This is not an interview, just a conversation to ensure alignment.
3. 15-30-minute interview with Tech9 Hiring Manager
4. 60-minute live technical interview with Head of AI at our client team with a focus on prompt design and work experience
5. 30-minute session with the client’s CTO, focused on team fit, technical vision, and your ability to contribute to the long-term goals of the platform.

Total time investment: Approximately 2-3 hours.
