About the role

  • Own reliability end-to-end for the auction sandbox and related services: deployment, upgrades, incident response, and operational hygiene.
  • Audit and consolidate today’s scattered components into a coherent system with a clear roadmap, interfaces, and single DRI ownership.
  • Build and automate containerized environments for latency-sensitive searcher workloads (e.g., atomic arbitrage), including reproducible builds and safe defaults.
  • Create first-class operator + user docs: runbooks, examples, troubleshooting guides, and “known failure modes” playbooks that searchers can trust.
  • Partner across teams (TEE, infra, product) to expand sandbox capability while tightening security, isolation, and developer experience.

Requirements

  • You have operated Linux production systems with real ownership: on-call/incident responsibility, upgrades, and long-lived maintenance.
  • Strong Linux + networking fundamentals; you debug below the dashboard (processes, sockets, filesystems, resource isolation).
  • Hands-on containers experience (Docker/Podman, image/build workflows, debugging inside containers). Ochestration familiarity is a plus.
  • A track record as a DRI for a complex service used by others (internal or external), including “boring” reliability work.
  • You write excellent docs, not as an afterthought, but as part of how systems become scalable and trustworthy.
  • User empathy: you ask about constraints, workflows, and success metrics before shipping changes that break someone’s setup.
Benefits
  • Significantly above market rate equity compensation package
  • Unlimited PTO with a high level of freedom and autonomy for your work
  • Attractive health coverage package for US employees
  • $3000 Yearly budget for your individual learning and development goals
  • Work alongside the brightest minds in the crypto space
  • Help save the world by ensuring crypto remains decentralized, permissionless and censorship-resistant
  • Remote working, while we have a preference for EU/US time zones, you can work from anywhere in the world
  • Paid travel - 2 x team on-site in different parts of the world per year plus periodic travel to events
