To become a member of this team, you need to be a software engineer fluent in Python, you need a genuine interest in the full open source infrastructure stack from metal to containers, and you need the ability to work in a high pressure operations environment with mission-critical services for global brand name customers.
As a member of the team you will gain experience in a broad range of cloud technologies. We evolve our offerings as the state of the art improves, so you get to stay current with the latest capabilities in open source infrastructure. We drive upgrades to keep our customers on the latest, best solutions.
