Data Scientist

🚀 Join Visor.ai as a Data Scientist!

At Visor.ai, we’re on a mission to revolutionize AI and automation for Contact Centers. By humanizing AI Agents, we help companies automate up to 85% of customer interactions, enhancing efficiency without compromising experience.

Founded in 2016 with big dreams and an innovation award, we've since grown into a trusted AI partner for leading brands across multiple industries and countries. Now, we're looking for a Data Scientist to join our AI Team and help us build the next generation of our intelligent platform!

🤖 Your Mission

As a Data Scientist, you'll play a critical role in designing and advancing the AI systems that power our platform. From classical NLP to cutting-edge LLM architectures, you'll shape the intelligence behind every conversation. Your responsibilities will include:

• Design and develop end-to-end NLP pipelines — from classical text processing to state-of-the-art LLM-powered architectures

• Build and maintain systems for intent detection, NER, entity extraction, and text classification, both standalone and as components feeding into larger LLM workflows

• Design and optimize Retrieval-Augmented Generation (RAG) systems — chunking strategies, vector store architecture, hybrid search (dense + sparse), and re-ranking pipelines

• Work with embedding models for semantic search, document retrieval, and intent classification in contact center contexts

• Design and implement agentic architectures — tool use, function calling, multi-step reasoning, and orchestration with frameworks like LangChain, LlamaIndex, or custom-built solutions

• Develop memory and context management strategies — short-term conversation memory, long-term user context, and context window optimization for multi-turn interactions

• Evaluate and benchmark models rigorously: hallucination detection, faithfulness scoring, latency/token cost tradeoffs, and continuous performance monitoring

• Integrate AI components into scalable, production-ready microservices with a focus on low-latency inference pipelines

• Collaborate with product and engineering to design new AI-powered features and drive innovation across the platform

• Conduct practical research with a scientific mindset and a focus on delivery — publications are possible and encouraged

😎 Your Skills & Experience

• 1-3 years of experience in a Data Science, AI or NLP Engineer role

• Strong programming skills in Python and core Data Science & ML libraries (Pandas, scikit-learn, NLTK, spaCy, Gensim)

• Solid understanding of NLP fundamentals — word embeddings, NER, information extraction, intent classification, text similarity

• Experience building and delivering ML products in production environments

• Hands-on experience with LLMs in production (OpenAI, Anthropic, Mistral, LLaMA, Gemini, or equivalent)

• Familiarity with RAG pipelines

• Experience with vector databases (Pinecone, Weaviate, Qdrant, pgvector, etc.) and modern embedding models

• Understanding of context window management, token budgeting, and prompt design for multi-turn conversations

• Experience with LLM Observability and Monitoring

• Experience with LLM frameworks such as LangChain, LlamaIndex, or Hugging Face Transformers

Bonus

• Experience with agentic frameworks, function calling, or structured outputs

• Exposure to voice AI pipelines or speech-to-text systems

• Comfortable with cloud infrastructure and ML deployment (AWS, GCP, or Azure)
