Role Title: Senior Linux Systems Engineer (Networking)

Role Description:
We are seeking an engineer to manage our core network infrastructure, which is built on Red Hat Enterprise Linux. This hybrid role requires a strong background in both Linux systems administration and network engineering. You will be responsible for configuring, securing, and maintaining the RHEL 9 hosts that function as our primary routers, firewalls, and service gateways.

Key Responsibilities:

Design, implement, and manage OS-level network security using firewalld and/or nftables (e.g., defining zones, services, and rich rules).
Configure and troubleshoot advanced networking on RHEL, including static routing, policy-based routing, and network-teaming.
Maintain and configure nginx as a reverse proxy for internal web services.
Manage KVM virtualization (libvirt) and associated bridged/routed networking for guest VMs.
Secure and manage remote access protocols, primarily OpenSSH.
Collaborate with the systems team on the migration to RHEL 9.
Contribute to infrastructure planning and the implementation of new systems or upgrades.
Management of updating and patching of the OS and software.
System Administration tasks as required, such as software deployment, upgrade installation, security remediation tasks and account management.
Management of monitoring and logging solutions.

Essential Requirements:

Expert-level knowledge of Red Hat Enterprise Linux (RHEL 8/9) administration (RHCE-level skills or equivalent experience).
In-depth understanding of the Linux networking stack (iproute2, firewalld, nftables).
Proven experience with nginx for reverse proxy and load-balancing configurations.
Strong understanding of core networking protocols (TCP/IP, subnetting, routing, DNS, DHCP).
Familiarity with RHEL-based virtualization (KVM, qemu).
In-depth knowledge of Red Hat Satellite Server, including lifecycle management, patch deployment, and system provisioning.
Thorough understanding of operating system standard operating environments (SOEs), including risk mitigation strategies and security hardening techniques.
Proficient in maintaining technical documentation, including process and architecture documentation using Confluence or similar platforms.
Demonstrated ability to communicate complex technical and policy requirements across varying levels of seniority.
Proven ability to manage multiple concurrent projects, while also providing business-as-usual (BAU) operational support.
Relevant Linux or Red Hat credentials.

Required Security Clearance Level: NV1 minimum/NV2 preferred

Location: ADL

Weekly Hours: 40
