AI/LLM Engineer

We are looking for an innovative AI/LLM Engineer to drive the advancement of our conversational AI capabilities. You'll join our Tech&Product team as an AI/LLM Engineer, focusing on prompt engineering, multi-agent orchestration, automated testing, and deploying integrations in production with LLM systems. You'll work closely with Backend Engineers to deliver world-class AI experiences to end users.

What will you do?

Core Development

• Design, optimize, and version prompts for production voice and chat LLM applications
• Architect and orchestrate multi-agent systems for complex conversations
• Build automated testing and validation frameworks for LLM outputs
• Implement prompt versioning, storage, and retrieval systems

System Integration & Deployment

• Collaborate with Backend Engineers to deploy and scale LLM-based systems
• Integrate LLMs with communication APIs (Twilio, WhatsApp, ElevenLabs)
• Implement RAG (Retrieval-Augmented Generation) solutions and vector search for multilingual environments
• Monitor performance metrics and conversation quality

Research & Innovation

• Research and prototype multi-agent frameworks (open-source and commercial)
• Experiment with cutting-edge conversational AI and real-time speech processing techniques
• Contribute to evolving the team's LLMOps best practices
• Continuously improve conversational quality, RAG pipelines, and reduce latency

Must have

• 2+ years hands-on experience with LLMs (OpenAI or similar, open-source models)
• Strong knowledge in prompt engineering and LLM optimization strategies
• Experience in evaluating LLMs, designing and running evaluation frameworks, creating test datasets, and defining success metrics
• Familiarity with automated testing pipelines, building CI/CD-integrated eval systems that run on every prompt change
• Experience in multi-agent architecture, from design to development of orchestration of complex LLM systems
• Good understanding of transformer architectures and proficiency in LLM frameworks such as LangChain, LlamaIndex, or similar frameworks
• Proficiency in Python
• Experience with RAG pipelines and vector databases
• Experience in cross-functional teams, ability to work in fast-moving environments where you own outcomes, not just tasks. You're comfortable with ambiguity and excited by the challenge of figuring things out.

Nice to have

• Experience in healthcare industries
• LLM integration with voice platforms (Twilio, ElevenLabs)
• Background in conversational AI, chatbots, voice assistants
• Knowledge of real-time speech processing and multi-modal systems
• Functional programming principles and advanced NLP
• Exposure to OOP stacks (.NET, PHP)
• Understanding of security and privacy in conversational AI
