  • Solid understanding of cloud-based infrastructure (AWS, GCP, or Azure).
  • Experience applying LLMs and generative AI in production, including prompt engineering, RAG, and LLM deployment.
  • Strong grasp of fundamental data science and machine learning techniques, with the ability to balance research and engineering tradeoffs.
  • Demonstrated ability to translate business problems into data solutions that drive business value.
  • Proven track record of shipping user-facing features with measurable impact.
  • Excellent written and verbal communication skills; ability to collaborate across data, engineering, and product teams.
  • Startup experience preferred.

Benefits:
