## About the Role

Do you have experience in Software development?, * Extensive data engineering experience with a track record of delivering complex projects.

 * Hands-on experience building and shipping AI/ML products in production.
 * Practical experience with LLM-based systems: RAG architectures, embedding pipelines, prompt and response logging, and evaluation frameworks.
 * Hands-on expertise with vector databases, graph databases, and knowledge graphs.
 * End-to-end exposure to the model development lifecycle, including experience training and deploying ML models in production environments.
 * Solid knowledge of LLM APIs, prompt engineering, and conversational AI patterns.
 * Strong expertise in MLOps and LLMOps, ensuring scalable, reliable, and monitorable model deployments.
 * Proficiency in Python and modern software development practices (testing, code review, CI/CD).

Desirable

 * Hands-on experience with cloud-native ML infrastructure platforms.
 * Knowledge of vector databases (e.g., Pinecone, Weaviate, Qdrant) and embedding models.
 * Experience with model serving frameworks (e.g., vLLM, TensorRT, Ray).
 * Background in forecasting, planning, or analytics applications.
 * Experience with A/B testing and experimentation frameworks for AI features.
 * Experience with model observability tools (e.g., LangSmith, W&B, MLflow).

## Description

* Contribute to the data architecture, design, and deployment of scalable Generative AI and Machine Learning systems into production environments.
 * Develop end-to-end GenAI features, including backend API services, model integration, model monitoring, evaluations, and deployments.
 * Integrate and optimise LLMs for specific use cases in business planning, including prompt engineering and RAG implementation.
 * Design and build the retrieval and knowledge layer powering our RAG and agentic workloads, such as vector databases, graph databases, knowledge graphs, hybrid search, and embedding pipelines.
 * Help design the knowledge graph that captures the semantics of customer models, metrics, hierarchies, and relationships.
 * Build the data plane for evaluation and continuous improvement, working with cutting-edge conversational and agentic AI technologies.
 * Engineer the feature and context pipelines that feed forecasting and anomaly-detection models at customer scale, balancing batch and streaming patterns.
 * Implement evaluation frameworks to measure and improve GenAI feature quality, including accuracy, latency, and user satisfaction metrics.
