Informacje o stanowisku

We are building an advanced AI platform focused on automating and enhancing tax-related processes across global finance organizations. The project leverages Large Language Models (LLMs), Generative AI, and Deep Learning to support consolidation, reconciliation, reporting, and interpretation of complex, unstructured tax documentation.

As a Senior Data Scientist, you will play a key role in designing, developing, and deploying scalable AI solutions that meet regulatory, legal, and performance requirements in cloud-based environments.

Senior Data Scientist – Platform & AI Assets (Generative AI & LLMs for Tax Solutions)



Your responsibilities

  • Collaborate with software engineers, data scientists, and business analysts to gather requirements, refine AI models, and integrate LLM-based solutions into enterprise platforms
  • Design and implement Generative AI and LLM solutions tailored to tax-specific use cases
  • Apply RLHF (Reinforcement Learning from Human Feedback) and advanced optimization techniques to improve model outputs
  • Embed AI workflows into consolidation, reconciliation, and financial reporting processes
  • Develop and deploy Deep Learning models for NLP and GenAI use cases
  • Leverage LLMs to analyze and interpret unstructured tax and legal documentation
  • Preprocess and prepare raw data, including text normalization, tokenization, and feature extraction for NLP models
  • Set up, train, fine-tune, and evaluate Large Language Models and other state-of-the-art neural networks
  • Conduct thorough testing, validation, and statistical analysis to ensure accuracy, robustness, and reliability
  • Optimize model performance across various computational environments, including cloud and edge platforms
  • Monitor, maintain, and scale generative models in production environments
  • Perform model audits to identify risks, biases, and compliance gaps
  • Partner closely with tax, finance, IT, and legal teams to ensure regulatory compliance and successful AI adoption
  • Research emerging trends in Generative AI and apply cutting-edge techniques to ongoing projects
  • Propose innovative AI-driven use cases to enhance tax and finance functions
