About the Role
We are seeking a GenAI/Data Scientist to join our AI Innovation Team. This role will focus on experimenting, optimising and applying Generative AI off the shelf models to extract valuable insights from large-scale patent datasets and enhance our search and analytics tools. You will collaborate with data scientists, product teams, and stakeholders across different geographies, driving innovation through LLMs (Large Language Models) and advanced AI methodologies.

Responsibilities:

• Perform EDA, design, build, and deploy pipelines utilizing LLM models to enhance patent search and analytics applications.
• Stay up to date with the latest research and developments in the field of natural language processing (NLP) and machine learning.
• Work on GenAI techniques like Prompt Engineering, RAG (Retrieval-Augmented Generation) and perform evaluation using frameworks to optimise LLM performance.
• Develop and implement machine learning workflows, focusing on the integration of GenAI with existing data infrastructure.
• Collaborate with the team to explore Generative AI use cases, including automated summarisation, natural language understanding, and text generation.
• Conduct experiments to evaluate model performance, identify areas for improvement, and implement enhancements.
• Perform continuous evaluations and improvements of models to handle large volumes of patent data.
• Work with stakeholders across teams to identify key areas for AI-driven innovation and enhancement in data products.
• Use Python, SQL, PySpark and related technologies to develop scalable solutions, focusing on large-scale data processing.

Qualifications:

• Demonstrate 3+ years of experience in data science, with a focus on NLP, Generative AI and LLMs.
• Proficiency in Python and experience working with transformer based LLMs and NLP frameworks (e.g. Hugging Face, Spacy, Pytorch/Tensorflow etc).
• Knowledge of Prompt Engineering, RAG techniques and various evaluation methodologies for integrating GenAI with search/retrieval systems and measure the quality.
• Experience working with cloud platforms like Azure, AWS, or GCP for machine learning workflows.
• Understanding of data engineering pipelines and distributed data processing (e.g., Databricks, Apache Spark).
• Strong analytical skills, with the ability to transform raw data into meaningful insights through AI techniques.
• Experience with LangChain / LlamaIndex, vector databases (e.g., FAISS), fine-tuning models on domain-specific data would be an advantage
