We are looking for a Linux System Engineer to help manage, maintain, and evolve our Linux-based in- store systems. This role combines deep Linux expertise with hands-on experience in packaging, troubleshooting, and device monitoring, while also leveraging web development skills to support interactive and dynamic menu board experiences.

Essential Job Functions

  • Design, package, and distribute software for Linux-based Digital Menu Board (DMB) devices.
  • Troubleshoot system-level issues (using syslog, journalctl, etc.) to ensure device stability and uptime.
  • Manage and optimize graphical systems (X, Wayland) and desktop environments (GNOME,KDE).
  • Collaborate with frontend and backend teams to integrate dynamic menu board features.
  • Implement and maintain monitoring solutions (Prometheus, Grafana, Datadog, or similar) with custom metrics for device performance and health.
  • Contribute to the hardening, security, and update processes for in-store Linux devices.
Requirements
  • Experience Range: 4–8 years of professional experience in Linux systems engineering, device management, or a related field.
  • Strong expertise in Linux (Debian/Ubuntu) and package management.
  • Hands-on experience creating packages for distribution (e.g., .deb, Snap).
  • Direct experience with on-premises, distributed physical devices is essential.
  • Familiarity with Linux logging and troubleshooting tools (syslog, journalctl).
  • Working knowledge of Linux graphical subsystems (X, Wayland) and desktop environments (GNOME, KDE).
  • Some frontend and backend web development experience — ideally with React, Python, Ruby, C/C++, Go, or Java.
  • Experience with monitoring tools (Prometheus, Grafana, Datadog) and building custom metrics.
  • Flexibility to work until 5:00 PM EST to ensure alignment with cross-time-zone teams.
  • Comfortable with a permanent work-from-home (WFH) arrangement and working with BYOD (Bring Your Own Device) setup, ensuring a secure and reliable working environment.

Preferred Qualifications

  • Experience building production Linux images for distributed devices.
  • Knowledge of device hardening, security, and OTA update processes.
  • Prior work in retail technology, digital signage, or in-store device ecosystems.
