What is a Unix Linux systems engineer?

Unix Linux Systems Engineers are IT professionals responsible for designing, implementing, maintaining, and troubleshooting Unix and Linux-based operating systems within an organization. They ensure server reliability, security, and performance, often managing system upgrades, patching, and user permissions. Their expertise is crucial for supporting enterprise applications, automating tasks through scripting, and maintaining system backups and disaster recovery processes. These engineers frequently work with other IT teams to ensure seamless integration between hardware, software, and network resources.

What are the key skills and qualifications needed to thrive as a Unix Linux systems engineer?

To thrive as a Unix/Linux Systems Engineer, you need deep expertise in Unix/Linux operating systems, shell scripting, and system administration, often supported by a degree in computer science or related certifications such as CompTIA Linux+ or Red Hat Certified Engineer (RHCE). Familiarity with configuration management tools (like Ansible or Puppet), virtualization platforms, and monitoring systems is commonly required. Strong problem-solving abilities, attention to detail, and effective communication are standout soft skills in this role. These skills ensure the reliability, security, and optimal performance of critical IT infrastructure in diverse business environments.

What are some common challenges faced by Unix Linux systems engineers in managing large-scale server environments?

Unix Linux Systems Engineers often encounter challenges such as ensuring system uptime, managing configuration consistency across numerous servers, and applying security patches without disrupting critical services. Automating repetitive tasks and monitoring system performance are essential skills to efficiently handle scale and prevent issues before they impact users. Collaborating closely with network, security, and application teams is crucial for seamless operations and resolving complex incidents quickly.

Job description

Title: Sr. RHEL Designer/Engineer (OT/SCADA)
Location: preference for Houston, TX or in Miami, FL, Houston, TX or Reston, VA
Term: Full Time, Direct Hire – remote but may need to travel to client locations periodically, especially at the start or kick off of a project.
Position Overview
Our client delivers turnkey clean energy and power infrastructure solutions across the Americas. We design, build, and operate advanced Battery Energy Storage Systems (BESS) and mission-critical networks for data centers, utilities, and industrial clients. Our technology-first mindset powers systems from SCADA to cloud—and everything in between.
About The Position
The Senior RHEL engineer will own the OS and container platform behind our on-premises energy-management deployments. You'll build and harden the tailored RHEL image and the containerized Ignition SCADA workload running on industrial PCs across U.S. data-center sites, and act as our deep RHEL authority and L3 escalation point. This is a platform-engineering and expertise role — not field installation.
You will own our OS architectures, container builds and configuration, and the runtime that hosts Ignition, while the SCADA team owns everything configured inside Ignition (tags, screens, logic). On the network side, the host firewall and OS-level networking (interfaces, routing, DNS, firewalld/nftables) are yours, while the physical and site network beyond the host NIC belongs to Operational Technology (OT).
Travel to third-party data-center sites is for troubleshooting and support only. The separate OT team commissions and deploys every machine, so you won't install systems in the field.
Responsibilities:
  • Build, version, and maintain a reproducible, turnkey RHEL image tailored to the SCADA host's needs (time sync, firewall/ports, storage, service ordering, resource tuning).
  • Own the SCADA container image end to end: Containerfile, base image, JVM, persistence, ports, hardening, scanning, and registry.
  • Run containers as systemd services via Podman and quadlets.
  • Harden the OS and images to a recognized baseline (CIS/STIG) and define a patching and lifecycle strategy for OT uptime and restricted/disconnected sites (offline/mirrored registry).
  • Troubleshoot full-stack — OS, container runtime, and application runtime behavior — remotely and on-site, handing off application-level issues to the SCADA team.
  • Own host-level networking and firewall configuration (interfaces, routing, DNS, firewalld/nftables, and port exposure for the SCADA container), and lead connectivity troubleshooting between the host and site infrastructure.
  • Document runbooks for the OT team and help define the connectivity and security posture.
  • Maintain the Windows image pipeline (Packer-based) in steady state once established: periodic patching, hardening updates, and image rebuilds.

Qualifications
  • 7+ years of senior, hands-on production RHEL/Linux engineering.
  • Container-native delivery: Podman, quadlets/systemd, building and owning container images (including packaging a JVM-based app such as Ignition), and registry management.
  • Reproducible, turnkey, versioned RHEL image building (bootc, Kickstart, Image Builder/osbuild, or Ansible-driven).
  • OS and image hardening to a recognized baseline (CIS/STIG).
  • Patch and lifecycle management for restricted/disconnected environments, including offline/mirrored content and registries.
  • Automation (Ansible) and version control.
  • Strong Linux networking and diagnostics: firewall administration (firewalld/nftables) and packet/connectivity tooling (Wireshark, tcpdump, ss, ip), plus containerized debug environments (toolbox).
  • Confidence operating as the RHEL authority, with strong documentation habits.
