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.

We are hiring a GenAI Engineer to help scale our LLM-powered systems from R&D prototypes into stable, enterprise-ready infrastructure. This is a hands-on engineering role requiring deep technical fluency and a strong sense of ownership. You'll be designing systems that not only function reliably at scale but also handle the complexity of real-time, multi-modal interaction.

This role is ideal for someone who started in software engineering and has transitioned into AI/LLM engineering, with a demonstrated ability to deploy and maintain robust LLM systems in production.

• Architect and scale production-grade LLM systems with a focus on reliability, latency, and predictability.
   
• Lead the design of LLM orchestration systems, including plugin APIs, prompt engineering workflows, and agent frameworks.
   
• Optimize and maintain multi-modal GenAI components, including real-time voice, NLP, and visual input modules.
   
• Build and maintain infrastructure on AWS, including tools and services such as SageMaker, Lambda, EKS/ECS, and DynamoDB.
   
• Own the stability and performance of LLM services through robust observability, monitoring, and scaling techniques.
   
• Translate experimental models into enterprise-ready, consistently performing products.
   
• Contribute to architectural decisions and roadmap planning for the AI platform.
   
• Actively share learnings, mentor others, and document practices to build a collaborative and high-ownership engineering culture.
   

• 5+ years of software engineering experience, with 2+ years focused on LLM/GenAI system development and deployment.
   
• Proven experience scaling LLMs from R&D environments into production, with strong attention to reliability and system behavior under load.
   
• Deep understanding of prompt operations, plugin orchestration, and agent-based frameworks for AI applications.
   
• Strong fluency in AWS infrastructure, including SageMaker, Lambda, EKS/ECS, and data services like DynamoDB.
   
• Familiarity with frameworks like LangChain, Ray, and general LLMOps tooling for orchestration, experimentation, and deployment.
   
• Experience working with multi-module systems, particularly involving real-time voice detection, TTS/STT, and multi-modal agents.
   
• Systems-thinking approach with a commitment to maintainability, performance, and observability.
   
• A mindset of ownership, collaboration, and knowledge-sharing.
   

• Background in conversational AI, edtech, or simulation-based platforms.
   
• Prior contributions to open-source AI infrastructure projects or public LLM benchmarks.
   
• Familiarity with real-time simulation or gaming engines integrated with AI components.
   

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

1. 10-15 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.
2. 60-minute live technical Interview, designed to evaluate your creativity and technical problem-solving in the context of LLM architecture and system design.
3. 45-minute live client interview with one of the AI leaders on the client team.. Expect a deep dive into your hands-on experience scaling LLM systems, multi-modal systems, your architectural thinking, and your approach to building stable, performant infrastructure.
4. 60-minute session with client team, focused on technical ability, and your ability to contribute to the long-term goals of the platform.

Total time investment: Approximately 4–5 hours.
