  • Deep familiarity with contract lifecycle and workflows at law firms or legal departments.
  • Analytical mindset and experience with handling large data sets, setting out testing frameworks and using data to inform decisions.
  • Experience with legal tech products (such as eDiscovery systems, clause extraction projects, legal research or contract management tools) and enthusiasm for the industry.


  • Experience with crafting code to prepare data, define model architectures and configure training pipelines.
  • Experience working with machine learning or AI-driven products, and an understanding of core machine learning concepts.
  • Basic coding experience in Python.
  • Prior experience working directly with large language models and prompt creation.
