Remote Network Firewall Engineer information

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

To thrive as a Remote Network Firewall Engineer, you need a solid understanding of network protocols, firewall configuration, and security principles, usually backed by a degree in computer science or a related field. Familiarity with firewall platforms (such as Cisco ASA, Palo Alto, or Fortinet), security tools, and certifications like Cisco CCNP Security or CompTIA Security+ is typically required. Strong problem-solving, attention to detail, and effective communication skills help you address security risks while supporting remote teams. These skills are crucial for protecting organizational networks, ensuring uptime, and responding quickly to emerging threats in distributed environments.

What does a remote network firewall engineer do?

A Remote Network Firewall Engineer is responsible for designing, implementing, managing, and monitoring firewall systems to protect an organization's networks from unauthorized access and cyber threats. Working remotely, they configure firewall policies, perform regular security assessments, troubleshoot network security issues, and ensure compliance with security standards. They also work closely with IT and security teams to update firewall rules and respond to incidents, ensuring the organization's data remains secure.

What are some common challenges faced by remote network firewall engineers and how can they be addressed?

Remote Network Firewall Engineers often encounter challenges such as troubleshooting complex network issues without on-site access, maintaining secure remote connections, and coordinating with distributed teams across different time zones. To address these, it's essential to use robust remote management tools, establish clear communication channels with team members, and keep thorough documentation of network configurations and changes. Additionally, staying up-to-date on the latest security threats and best practices helps ensure effective firewall management and incident response.

What is the difference between Remote Network Firewall Engineer vs Remote Network Security Analyst?

RHEL Systems Engineer

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.
