Requirements

• At least four years of experience building ML/AI systems in production with hands-on LLM experience
• Deep understanding of LLM ecosystem including model architectures and fine-tuning approaches
• Hands-on experience with prompt engineering, LLM pipeline design, agentic frameworks (LangGraph, Pydantic AI, or equivalent), RAG patterns, vector databases, and deploying LLM applications
• Strong Python skills; Kotlin knowledge a plus
• Excellent communication skills and proficiency in English

Responsibilities

• Designing and building ML/LLM solution for data ingestion, knowledge extraction and retrieval, and reasoning
• Creating datasets, metrics, and pipelines that drive measurable improvements
• Architecting and improving AI agents, including prompt engineering, model selection, and inference optimization
• Contributing to MLOps practices including orchestration, observability, and experiment tracking
