Staff Backend Software Engineer, Userdata

    • New York, NY

Beeswax’s mission is to build great advertising software. Our product is an easy to use, massive scale and high availability advertising platform founded by industry veterans who worked together at Google. We offer our customers the most extensible and transparent advertising system in the world and process millions of transactions per second. We offer our employees a culture of transparency and one with many challenging problems to solve - whether our employees are competing at game night or coming up with bee puns, they remain a close-knit group.

Beeswax is looking for a Staff Backend Software Engineer to join our Userdata team.

These pipelines feed caches that are then queried by our real-time infrastructure at millions of queries per second.

Because of the scale of our data that the Beeswax Userdata team works with, engineers on this team have a meaningful impact that can directly affect our bottom line. If large volume, complex ETL is your jam (or honey), then keep reading!
