About the role

  • Northern Light is seeking an experienced Senior Linux Infrastructure Engineer to take hands-on ownership of our Linux-based infrastructure.
  • In this role, you'll be responsible for operating, maintaining, and evolving a mission-critical environment that runs on a mix of bare-metal and virtualized systems in our private colocation datacenter.
  • This is a highly technical, hands-on position for someone who enjoys working close to the hardware, values operational excellence, and thrives in environments where reliability, security, and scalability matter.

Responsibilities

  • Operate and maintain a Linux infrastructure of ~70 HPE DL360 Gen9/Gen10 bare-metal servers and ~150 virtual machines
  • Develop and maintain standard operating procedures covering:

Requirements

  • Must be authorized to work in the United States (unfortunately, we cannot sponsor visas).

  • Proven experience designing and maintaining high-availability and redundant architectures in production - not just operating them
  • Direct, hands-on experience with HPE ProLiant (or equivalent enterprise) servers, including iLO/IPMI management, firmware updates, hardware diagnostics, and component replacement
  • Experience performing all physical datacenter tasks independently: rack and stack, structured cabling, labeling, power management, and hardware lifecycle tracking in a private colo or equivalent environment
  • active experience with vulnerability management tools (Tenable, Qualys, or equivalent): scan interpretation, remediation prioritization, and patch compliance tracking
  • Track record of leading incident response, conducting post-mortems, and producing root-cause analyses with lasting corrective actions
  • strong technical documentation discipline (SOPs, runbooks, infrastructure diagrams) and ability to communicate clearly to both technical and non-technical stakeholders
  • Familiarity with Docker and Kubernetes

Nice to have

  • rack and stack, structured cabling, labeling, power management, and hardware lifecycle tracking in a private colo or equivalent environment
  • Production-level administration of VMware vSphere/ESXi environments (vCenter, VM lifecycle, resource pools, snapshots, HA/DRS) and KVM-based virtualization (libvirt, virt-manager, bridged/NAT networking)
  • experience supporting platform migrations (e.g., VMware to open-source hypervisors) is a strong plus
  • Experience managing on-prem package repository infrastructure (Foreman or equivalent) and enforcing controlled patching workflows across a large server fleet
  • Hands-on experience with enterprise monitoring and alerting platforms (LogicMonitor, Zabbix, Nagios, or equivalent), including building meaningful alerting thresholds and dashboards
  • active experience with vulnerability management tools (Tenable,
  • RHEL-based distributions are required
  • Oracle Linux 9 is strongly preferred
