Senior Engineer - Kubernetes
Datum’s mission is to help 1k clouds thrive in the AI era by unlocking internet superpowers for every builder. 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? Read on! The Role We're seeking a Senior+ Engineer to build and run critical components of the Datum Cloud control plane. This is a senior technical leadership role focused on designing and building features woven into our open source business operating system, Milo, a toolkit for modern AI-forward alt-clouds. You'll work extensively with distributed systems, vendor APIs, networking protocols, software-defined networking, and cloud-native infrastructure while solving complex orchestration challenges across multiple cloud providers and edge locations.
