DoubleZero is hiring a Open Role: Exceptional Systems Builders in Malbec Labs — Remote. The overview below is synthesized from the employer posting on jobs.ashbyhq.com: factual requirements and scope are preserved, but prose is rewritten with editorial context. Verify details and apply via the employer link.
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
Company context from the listing:
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.
In short, DoubleZero is a new Internet for distributed systems. It is supported by many independent contributors.
Build a standout application
For the Open Role: Exceptional Systems Builders at DoubleZero, reviewers look for concise evidence over buzzwords. Mirror the language of the posting sparingly, quantify support or delivery outcomes, and show how you handled ambiguity, time-zone collaboration and user empathy. Keep your resume to impact, keep your cover note to one page, and link to artifacts — tickets resolved, docs shipped, dashboards owned — that prove you can operate in a fast-moving Web3 team. Prepare to discuss a time you turned a confusing user report into a clear fix and how you measure quality in support and operations.
Web3 hiring values reliability: on-time follow-through, clear writing, and a track record of improving runbooks and tooling. Treat the application as a work sample. For interviews, be ready to walk through how you prioritize across time zones, handle a difficult user, and decide when to escalate versus resolve directly. Show how you document decisions so the next teammate benefits.
In a distributed Web3 org, trust builds through written clarity. Use the cover note to demonstrate it. Add links to public work, keep formatting scannable, and close with a clear ask. Hiring managers skim — make impact obvious in the first half-page.
Career growth in Web3 rewards continuous learning. Follow protocol changelogs, practice with testnets, and contribute to open issues. Small, consistent contributions compound into credibility more than one-off credentials.
