• Hands‑on experience with modern Machine/Deep Learning frameworks such as PyTorch, TensorFlow, or Hugging Face Transformers.
• Familiarity with both pre‑training and fine‑tuning of large‑scale models.

• A strong understanding of probability, statistics, machine learning and large‑data set manipulation.
• Proven ability to produce reliable and maintainable Python code and adapt to new languages and technologies.
• Strong communication skills to present findings to a diverse business‑focused audience.
• Drive for continued learning through internal and external focus to develop industry‑leading solutions.
