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 an SRE who thinks like a systems architect and builds reliability through automation. You should have lived inside large production environments and be allergic to manual processes. WHAT YOU’LL DO - Design and build automation-first reliability systems in Go - Treat infrastructure as pipelines: provisioning, observability, deployment, failover - Build internal tooling, control planes, and reliability infrastructure - Own production readiness, alerting, and operational maturity - Work across protocol, networking, and hardware boundaries WHAT WE’RE LOOKING FOR - Big tech SRE / Production Engineering background or similar - Strong Golang engineering skills in production environments - Systems thinker: you design for scale, reliability, and operational simplicity - Experience building internal platforms rather than just operating existing ones - Comfort with distributed systems, networking, and low-level system behavior 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.
