Python LLM Fine-Tuning NLP RAG Architectures Vector Databases SQL Generation PyTorch / Transformers
As an AI/ML Engineer at Nexalytica, you will design and improve the core intelligence layer that powers our conversational analytics platform. Your work will directly determine how well our product understands user questions, generates accurate SQL, and delivers trustworthy insights from complex datasets.
You will build and refine retrieval-augmented generation (RAG) pipelines, develop prompt engineering strategies, and create evaluation frameworks that measure answer quality at scale. You will also work on anomaly detection models, predictive analytics features, and the statistical reasoning capabilities that set Nexalytica apart from simple query translators.
This is a high-impact role on a small team. You will collaborate closely with product designers and full-stack engineers to ship features that real customers use every day. If you care about making advanced AI capabilities feel simple and reliable, this is the place to do it.
