Stay informed on emerging trends across AI, automation, tax technology, data science, and intelligent systems
Help evaluate external tools, platforms, and ecosystem opportunities relevant to Tax Transformation
Contribute to a culture of experimentation, innovation, and continuous improvement

Qualifications & Experience

Master’s degree or PhD in Computer Science, Data Science, Machine Learning, AI, or related quantitative discipline preferred
3+ years of experience building and deploying machine learning or AI solutions in production environments
Strong proficiency in Python and modern data science libraries including Pandas, NumPy, Scikit-Learn, TensorFlow, or PyTorch
Experience with NLP, generative AI, LLMs, vector databases, embeddings, or knowledge graph technologies preferred
