Razer is **a place to do great work**, offering you the opportunity to make an impact globally while working across a global team located across 5 continents. Razer is also **a great place to work,** providing you the unique, gamer-centric #LifeAtRazer experience that will put you in an accelerated growth, both personally and professionally.## **Job Responsibilities :**We are seeking a highly skilled and innovative Data Scientist to join our software team, leveraging user configuration data and software configuration schemas to fine-tune large language models (LLMs) in the 8B–32B parameter range. You will build an AI-powered configuration assistant that combines LLM fine-tuning, prompt engineering, retrieval-augmented generation (RAG) with VectorDB & GraphDB, and model optimization (including quantization) to deliver accurate, fast, and cost-effective recommendations to users. This is a full-stack applied AI role, covering data handling, model training, deployment, monitoring, and optimization in production.**Key Responsibilities****1. LLM Fine-tuning & Evaluation*** Fine-tune and adapt LLMs for domain-specific configuration assistance.* Apply instruction tuning, LoRA, RLHF, and domain adaptation.* Establish automated evaluation pipelines for accuracy, latency, and safety.**2. Prompt Engineering*** Design, test, and optimize prompt strategies for varied scenarios, personas, and workflows.* Develop reusable prompt templates and dynamic context injection logic.* Run A/B tests to measure prompt impact on user outcomes.**3. Retrieval-Augmented Generation (RAG) with VectorDB & GraphDB*** Implement semantic retrieval with **VectorDB** (e.g., FAISS, Pinecone, Weaviate).* Build **GraphDB** (e.g., Neo4j, TigerGraph) pipelines to represent and query configuration relationships.* Combine embedding search with graph reasoning for richer context in LLM outputs.* Optimize retrieval for both latency and relevance.**4. Model Quantization & Optimization*** Apply quantization, pruning, and distillation to right-size LLMs for deployment.* Benchmark trade-offs between quality, speed, and cost across CPU/GPU/edge.* Collaborate with infrastructure teams on inference optimization.**5. Data Handling & Engineering*** Extract, clean, and structure configuration and schema data (JSON, YAML, XML).* **Proficiency with SQL** for querying and transforming relational datasets.* Build automated pipelines for continuous retraining and RAG index updates.* Apply schema-aware data modeling for improved retrieval and training.**6. Production Deployment & Monitoring*** Collaborate with software engineers to integrate AI into live products.* Develop APIs and microservices for LLM-powered features.* Set up monitoring dashboards, drift detection, and feedback loops.* Implement safety guardrails to prevent hallucinations and unsafe recommendations.**7. Security, Privacy & Compliance*** Ensure compliance with data privacy regulations (e.g., GDPR, SOC 2).* Apply data anonymization and access control practices.* Design output filtering to avoid sensitive or incorrect recommendations.## Pre-Requisites :**Requirements****Must-Have:*** 3+ years in Data Science, ML, or NLP with hands-on **LLM fine-tuning** experience.* Proven skills in **prompt engineering** and **RAG pipeline development**.* Experience with **VectorDB** and **GraphDB** integration.* Hands-on experience with **model quantization** and optimization.* Proficiency in **Python** (Hugging Face Transformers, PyTorch, LangChain).* **Proficiency with SQL** and relational data modeling.* Knowledge of YAML, JSON, XML, and schema-based data structures.* Strong grasp of MLOps principles for production deployment.**Preferred:*** Experience with GPU optimization tools (ONNX Runtime, TensorRT).* Background in software configuration management systems.* Familiarity with CI/CD, Docker, Kubernetes for ML services.* Experience in LLM evaluation frameworks (e.g., Ragas, HELM, OpenAI Evals).At Razer, you'll be at the forefront of the most exciting industry in the world — gaming.
