As a team, we are a collaborative, cross-functional group with backgrounds in ETL, information retrieval, and distributed systems. We provide thought leadership across a variety of mediums including open code repositories, publishing blogs, and speaking at conferences.

You will lead and manage a talented team of engineers. You’ll perform frequent 1on1s, deliver quarterly reviews, lead in “All Hands” discussions, onboard, coach and mentor new and existing team mates.
