Full Job Description

đź“‹ Description

  • • Own and evolve the global control plane that orchestrates every VM, GPU, and bare-metal instance across Vultr’s 32 data centers—directly impacting the experience of 1.5 million users and the stability of a $3.5 B cloud platform.
  • • Design, deploy, and harden hypervisor fleets at scale: automate the life-cycle of KVM/QEMU/libvirt hosts, enforce golden-image standards, and eliminate single points of failure before they surface to customers.
  • • Build self-healing network automation for Open vSwitch fabrics and BGP-driven edge routing; reduce MTTR from hours to minutes by codifying runbooks into deterministic, testable pipelines.
  • • Instrument deep observability into every layer—compute, storage, network—using Grafana, Sentry, and SumoLogic; define SLIs/SLOs that translate business goals into measurable reliability targets.
  • • Lead production incident response: coordinate cross-functional war rooms, drive blameless postmortems, and turn outages into systemic improvements that prevent recurrence.
  • • Continuously profile and tune performance: from NUMA topology on bare metal to NUMA-aware CPU pinning in guests, squeeze every microsecond of latency and every watt of efficiency.
  • • Evolve CI/CD and configuration management (GitLab CI, Puppet) to deliver infrastructure changes dozens of times per day with zero-downtime guarantees and automated rollback.
  • • Partner with software, network, and product teams to translate customer-facing features into rock-solid infrastructure requirements, ensuring new services launch with reliability baked in.
  • • Create living documentation—architecture decision records, runbooks, and automation playbooks—that empowers the entire engineering org to operate at your level.
  • • Mentor junior SREs and systems engineers through pair debugging, design reviews, and weekly tech talks, raising the reliability bar across the company.
  • • Champion a culture of toil reduction: every manual step is a candidate for code, every alert is a candidate for automation, and every metric is a candidate for an SLO.
  • • Influence long-term platform strategy: capacity forecasting, multi-region disaster recovery, and chaos engineering practices that keep Vultr ahead of customer growth.
  • • Stay hands-on with low-level Linux internals—cgroups, eBPF, kernel tracing—and turn arcane system behavior into deterministic, reproducible fixes.
  • • Contribute upstream to open-source projects (libvirt, QEMU, OVS) and bring back patches that improve Vultr’s operational posture and the broader community.
  • • Participate in an on-call rotation that respects work-life balance: follow the sun with global teammates, automate yourself out of 3 a.m. pages, and use every incident as a forcing function for better tooling.

🎯 Requirements

  • • 5+ years running large-scale distributed systems and control-plane infrastructure in production, preferably in a cloud or hosting environment.
  • • Expert-level proficiency with KVM, QEMU, and libvirt; you can debug live-migration failures and NUMA mis-alignments without googling man pages.
  • • Strong networking chops: hands-on experience with BGP, Open vSwitch, and Linux traffic control; you’ve automated network changes via Ansible or custom Go/Python tooling.
  • • Deep observability mindset: you’ve implemented SLIs/SLOs, built Grafana dashboards, and tuned alert fatigue out of existence with Sentry and SumoLogic.
  • • Proficiency in PHP (or similar) for scripting and automation; you treat infrastructure as code and code as infrastructure.

🏖️ Benefits

  • • 100 % company-paid medical, dental, and vision premiums for employee-only plans—zero payroll deductions for core coverage.
  • • 401(k) with 100 % match up to 4 % of salary, vested immediately—start building retirement wealth from day one.
  • • $2,500 annual professional-development stipend—conferences, courses, certs, or that new homelab you’ve been eyeing.
  • • Remote-first culture with $500 first-year home-office setup stipend and $400 annual refresh—plus up to $75/month internet reimbursement.
