about-project :


  • 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.

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

requirements-expected :


  • 6+ years of hands-on experience in Data Science or Applied Machine Learning
  • Strong programming skills in Python, with experience using PyTorch, TensorFlow, and related ML libraries
  • Solid understanding of object-oriented design patterns, concurrency/multithreading, and scalable AI model deployment
  • Proven experience in developing, training, and fine-tuning LLMs and advanced AI models
  • Practical knowledge of Deep Learning architectures and techniques, including CNN, RNN, LSTM, GANs, Transformers, RAG, and LangChain
  • Expertise in Prompt Engineering and working with vector databases
  • Proficiency in NLP tools and techniques, including RegEx, SpaCy, NLTK, semantic extraction, and text representation
  • Experience with Vector Databases (e.g., Milvus, PostgreSQL) and general database technologies
  • Familiarity with Azure Cloud Platform and cloud-native AI solutions
  • Hands-on experience with Docker, Kubernetes, and CI/CD pipelines
  • Strong analytical skills with the ability to perform statistical evaluation and model optimization
  • English proficiency at B2 level or higher
