DoubleZero builds a global network of private fiber-optic links—using underutilized carrier lines and partner-operated infrastructure—to provide low-latency, high-bandwidth connectivity and permissioned testnet access for blockchain validators and RPCs.
We’re looking for a network engineer with a true CCIE-level routing & switching background who is equally comfortable writing production code. This is not a traditional NOC role — it’s for someone who treats networks as software systems. WHAT YOU’LL DO - Design and operate large-scale, high-availability, low-latency networks - Work on BGP, EVPN, MPLS, segment routing, and carrier-grade routing architectures - Build automation frameworks in Go and Python to manage network config, deployment, and monitoring - Partner with hardware, protocol, and systems engineers to optimize for latency, reliability, and scale - Debug real-world production network failures across physical and virtual layers WHAT WE’RE LOOKING FOR - CCIE or equivalent hands-on routing & switching expertise - Strong experience in ISP / carrier / backbone network environments - Solid production Go + Python experience (not just scripts) - Deep understanding of routing protocols, convergence, and network failure modes - Experience treating infrastructure as code and systems as software - Preference for telecom / ISP / infrastructure backgrounds over HFT ABOUT DOUBLEZERO DoubleZero is a high-performance, permissionless global network purpose-built for distributed systems. The mission is simple: increase bandwidth and reduce latency. DoubleZero increases bandwidth by filtering junk data that currently plagues validators and other network operators. DoubleZero reduces latency by connecting these filters via underutilized private fiber links, forming a mesh network. By combining these improvements and routing the right data through optimized, low-latency paths, the DoubleZero protocol empowers blockchains and other systems to achieve performance levels previously impossible. In short, DoubleZero is a new Internet for distributed systems. It is supported by many independent contributors. Among them, DoubleZero Foundation drives the adoption, decentralization, security, and advancement of the protocol. Malbec Labs develops the technical components of the protocol itself. We look forward to hearing from you.
