AI assistant / chatbot for querying advertising data, content data and business performance.
Python, PyTorch, Transformers, LangChain / LlamaIndex, FastAPI, Vector Database, PostgreSQL, ClickHouse, Redis, Docker, [protected info], NestJS, Golang, TikTok API, Facebook API.
Experiment with different model architectures and approaches to improve model quality and system performance.
Improve LLM response quality by using retrieval, memory, structured outputs, validation and post-processing.
Design guardrails and fallback strategies to reduce hallucination, incorrect answers and unsafe outputs.
Work with vector databases such as Qdrant, Milvus, Weaviate, Pinecone, FAISS or equivalent tools.
Optimize retrieval quality using hybrid search, reranking, metadata filtering and query rewriting.
Monitor and improve agent reliability, response quality and tool execution accuracy.
Apply fine-tuning techniques such as LoRA, QLoRA, instruction tuning or supervised fine-tuning when suitable.
Optimize model inference using quantization, batching, caching and distributed inference.
Proactively suggest improvements to AI pipeline, model quality, data quality and system performance.
Collaborate with QA team to design test cases for AI outputs, RAG results and agent behavior.
Use AI tools such as ChatGPT, Claude, Gemini or equivalent tools to support research, coding, debugging, documentation and evaluation.
Working in a startup environment, the product develops quickly and has many opportunities to participate in AI system design from an early stage.
