  • Familiarity with AI/ML: Proficient knowledge of AI and machine learning platforms/APIs, frameworks (e.g., TensorFlow, PyTorch), and algorithms
  • Cross-functional Collaboration: Track record of optimizing technical outcomes that account for engineering, product, and business partners and requirements
