Not every great engineer fits into a predefined job description. We’re open to talking with exceptional technical builders who have done hard things before and want to do them again — at a bigger scale, with sharper constraints, and more freedom to shape the work. This role is intentionally undefined. We’re looking for people who: Have built or operated complex systems in demanding environments Think deeply about performance, correctness, and architecture Are comfortable working across layers: software, systems, networks, and hardware Gravitate toward hard problems without needing a roadmap handed to them Care more about the system than the title We care less about specific tools or credentials and more about how you think, what you’ve shipped, and the kinds of problems you’re drawn to. If you’ve: Built infrastructure that other engineers depend on Solved problems that don’t come with documentation Owned systems where failure wasn’t an option Or just consistently found yourself at the hardest edge of the stack We’d like to talk. 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 with underutilized private fiber links in the form of 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 reach performance levels that were previously impossible. In short, DoubleZero is a new Internet for distributed systems. It is supported by two organizations: DoubleZero Foundation, which drives the adoption, decentralization, security, and advancement of the protocol; and Malbec Labs, which develops the technical components of the protocol itself. We look forward to hearing from you
