Summary: We are looking for a Machine Learning Engineer (RAG Specialist) to join an AI hyperscaler client on a 6–12 month contract. The role involves designing, building, and optimizing Retrieval-Augmented Generation (RAG) systems for large language model solutions. This position offers the chance to work with advanced infrastructure and collaborate with leading AI teams. The ideal candidate will have proven expertise in RAG techniques and experience with large-scale AI/ML deployments.
Key Responsibilities:
- Design, implement, and optimize RAG pipelines for large-scale AI/ML deployments.
- Develop and maintain data ingestion, retrieval, and indexing workflows across distributed environments.
- Work with vector databases, embeddings, and information retrieval systems to ensure high performance and low latency.
- Collaborate with researchers, ML engineers, and data scientists to integrate RAG into production-grade LLM applications.
- Contribute to scaling and deployment strategies across a hyperscaler environment (cloud-native).
- Monitor, debug, and fine-tune ML pipelines for robustness and efficiency.
- Produce high-quality documentation and knowledge transfer for internal stakeholders.
Key Skills:
- Proven expertise in RAG (Retrieval-Augmented Generation) techniques and real-world implementation.
- Strong experience with LLMs, transformers, and embeddings.
- Hands-on experience with vector databases (e.g., FAISS, Pinecone, Weaviate, Milvus, Vespa).
- Deep knowledge of Python and modern ML/AI frameworks (e.g., PyTorch, Hugging Face, LangChain, LlamaIndex).
- Strong background in distributed systems, data pipelines, and cloud-native environments (Azure, AWS, or GCP).
- Previous work with AI hyperscalers or large-scale ML infrastructure is highly desirable.
- Excellent problem-solving skills, with the ability to optimize systems for performance and scalability.
