We’re working in the open to bring the foundational capabilities that all the big guys use (private networking, peering, direct interconnection, etc) into the hands of builders and modern “alt clouds” — no network team required.One of Datum’s core values is to be connectors: of applications, services, networks, and people. As such, this role (just like all roles at Datum) will work directly with users, customers, partners, and the broader community.Another key value is to be open by default, from how we license our code (AGPLv3) to how we communicate, engage with, and document our work. We believe this engenders trust from our customers and community, but also because open is the best way to build. It's more secure, more operable, and even more enjoyable.Still interested?
