- Design, develop and deploy machine learning and Generative AI solutions for conversational understanding, summarisation, classification and insight generation.
- Build and optimise LLM-powered applications using prompt engineering, model orchestration and foundation models.
- Design and implement RAG pipelines integrating structured and unstructured data sources to generate context-aware and reliable insights.
- Develop embedding-based solutions and vector search systems for semantic search and information retrieval.
- Build AI agent workflows using frameworks such as LangChain, LangGraph, LlamaIndex or similar.
- Perform data exploration, feature engineering, model development, evaluation and optimisation.
- Integrate foundation models using AWS Bedrock and leverage AWS SageMaker for machine learning workflows.
- Develop scalable data pipelines and distributed processing systems to support real-time and batch AI workloads.
- Implement model evaluation frameworks, LLM guardrails and responsible AI practices.
- Apply MLOps and LLMOps practices, including CI/CD, model versioning, automated evaluation, deployment and monitoring.
- Monitor and optimise production AI/ML solutions using Datadog, AWS CloudWatch or similar observability tools.
- Analyse model outputs, communicate findings and continuously improve model performance and business impact.
- Collaborate with product, business and engineering teams to translate requirements into effective AI-driven solutions.
Requirements:
- 7 - 10 years of experience in Data Science, Machine Learning, AI/ML Engineering or related fields.
- Strong proficiency in Python and hands-on experience developing production-grade AI/ML applications.
- Strong understanding of statistical modelling, machine learning algorithms, predictive analytics and data analysis.
- Practical experience developing Generative AI applications using LLMs, prompt engineering and model orchestration.
