We are seeking a dynamicAI Engineer with 2-4 years of experience to join our growing team. You will be responsible for designing, building, and deploying cutting-edge AI solutions that deliver autonomous, user-facing capabilities. This role focuses on creating LLM-powered applications & data enrichments, agenting workflows, and intelligent systems that directly impact our users\’ experiences.

What You\’ll Do:

As an AI Engineer on our team, you will take ownership of end-to-end AI solution delivery, from initial concept through production deployment and ongoing optimization. You\’ll architect and implement LLM-powered applications&enrichments, multi-agent workflows, and autonomous AI systems that directly impact our users\’ experiences. Your work will involve orchestrating large language models, building sophisticated prompt engineering frameworks and fine-tuning, as well as creating robust RAG (Retrieval-Augmented Generation) systems using vector databases and semantic search technologies.

You\’ll be responsible for deploying and operating these LLM applications at scale, ensuring they perform reliably in production environments. This includes containerizing AI services, implementing deployment pipelines for rapid iteration, and establishing monitoring systems that track both performance metrics and AI-specific indicators like response quality, hallucination rates, and autonomous decision accuracy.

Your role encompasses ensuring our AI systems are production-ready and enterprise-grade. You\’ll manage the infrastructure that powers our AI applications, optimizing for both performance and cost-effectiveness, establishing automated evaluation frameworks for LLM applications, and build robust fallback mechanisms. You\’ll ensure our AI systems meet security and compliance requirements while maintaining the ability to rapidly iterate and improve AI capabilities based on user feedback and performance data.
