Industry UsageIndustrial automation, OT systems, manufacturingIT infrastructure, corporate networks, data centers
Job FocusOT network security, industrial protocols, system integrationNetwork setup, troubleshooting, security, and maintenance

The Remote Ot Network Engineer and Remote Network Engineer roles share certifications and work environments but differ mainly in industry focus. The Ot Network Engineer specializes in industrial and operational technology networks, while the Network Engineer focuses on IT infrastructure across various sectors.

What are the key skills and qualifications needed to thrive as a remote OT network engineer?

To thrive as a Remote OT Network Engineer, you need a solid background in network engineering, industrial control systems (ICS), and operational technology security, typically supported by a relevant degree and certifications such as Cisco CCNA/CCNP or GIAC GICSP. Familiarity with SCADA systems, firewalls, VPNs, and remote monitoring tools is essential for managing and securing OT networks. Strong problem-solving skills, attention to detail, and the ability to communicate complex technical issues clearly are critical soft skills for this role. These skills ensure the reliability, safety, and security of critical infrastructure while effectively supporting remote operations.

What is a remote OT network engineer?

A Remote OT (Operational Technology) Network Engineer is a professional who designs, implements, and manages the networks that support industrial systems and processes, such as those found in manufacturing plants, utilities, and critical infrastructure. They work remotely to ensure the reliability, security, and efficiency of networks that connect operational devices like sensors, controllers, and industrial machines. These engineers play a key role in integrating IT and OT environments, troubleshooting connectivity issues, and protecting against cybersecurity threats. Their work helps maintain continuous and safe operations in industries that rely heavily on technology.

How does a remote OT network engineer typically collaborate with on-site teams to address urgent network issues?

As a Remote OT Network Engineer, collaboration with on-site teams is essential, particularly when troubleshooting critical network incidents. You’ll often rely on clear documentation, remote diagnostics, and regular video or phone communication to guide on-site technicians through physical checks and interventions. Building strong relationships with local staff and establishing effective escalation procedures ensures that urgent issues are resolved efficiently, even when you’re not physically present. Familiarity with remote management tools and a proactive communication style are key to success in this environment.

RHEL Systems Engineer

ASCENDING LLC

Houston, TX • On-site, Remote

Full-time

Posted 17 days ago

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.
