  • Design, build, and manage distributed data science inference systems across multi-cloud environments, including AWS and GCP (and more).

What we’re looking for:

  • Bachelor’s or Master’s degree in an engineering discipline (BEng/MEng)

  • 1-2 years of experience in a technical field

  • Competency in Python and SQL

Compensation (for US based employees):

The anticipated salary for this position is between $100,000 and $130,000. Within the range, individual pay is determined by factors such as job-related skills, experience, and relevant education or training. If your compensation expectations fall outside of this range, it may still be worth having a conversation.
