We are seeking a hands-on Linux Systems Engineer to build, maintain, and scale our on-premise infrastructure. This role is focused on bare-metal Linux systems, with significant ownership across server provisioning, storage, and system reliability.

The ideal candidate is detail-oriented, highly disciplined, and comfortable operating in a demanding, production-critical environment. This is not a cloud-focused role-success requires deep experience with physical infrastructure, Linux internals, and automation in a high-performance setting.

Responsibilities

  • Build, provision, and maintain bare-metal Linux servers, including OS installation, configuration, and lifecycle management
  • Own server infrastructure from hardware through operating system and core services, ensuring stability and performance
  • Configure and manage storage systems, including ZFS and enterprise storage platforms (e.g., NetApp, Dell, or similar)
  • Monitor system health and performance; troubleshoot issues and implement durable, long-term fixes
  • Develop and maintain automation using Ansible and Bash to standardize provisioning, configuration, and operations
  • Perform system patching, upgrades, and capacity planning across a growing server fleet
  • Participate in incident response, root cause analysis, and continuous improvement of system reliability
  • Collaborate with engineering and infrastructure teams to support application performance on Linux systems
  • Contribute to documentation, runbooks, and operational best practices

Support data center operations as needed, including hardware troubleshooting, racking, cabling, and server replacements

  • Travel to data centers periodically for maintenance, expansions, and issue resolution
