Linux / Systems / Network Engineer (Infrastructure Platform Focus)

Linux Infrastructure Engineer

Location: Johannesburg working Hybrid
Type: Contract to Permanent Conversion

About the Opportunity

We are looking for an experienced Linux / Systems / Network Engineer to join a growing infrastructure team at a leading organization undergoing a major technology transformation.

As the company modernizes its on-premise infrastructure and prepares for a hybrid future, you'll play a critical role in building, supporting, and maintaining stable and secure systems. This is not a cloud-native DevOps role its hands-on, infrastructure-focused, and highly technical, ideal for engineers who thrive working at the systems and networking layer of enterprise environments.

Key Responsibilities

• Provision and configure VMware virtual machines to support evolving infrastructure needs

• Install, configure, and maintain Linux-based systems (e.g., RHEL, Ubuntu, CentOS)

• Support systems across multiple environments (development, staging, production)

• Configure and manage critical network services and components, including:

  • DNS servers and records

  • TLS/SSL certificates

  • Load balancers (front-end/back-end rules)

  • Firewall and routing rules

• Troubleshoot and optimize system and network performance

• Assist in the integration of APIs for internal systems and services

• Implement and support security protocols in line with compliance requirements

• Collaborate with the Infrastructure/IS Operations Manager to ensure system reliability and business continuity

• Create and maintain clear documentation of systems, processes, and configuration standards

Must-Have Skills & Experience

• 5-10 years in roles such as Linux Systems Engineer, Infrastructure Engineer, or Systems Administrator

• Strong command of Linux operating systems:

  • Systemd, kernel tuning, package management, file systems

• Solid understanding and hands-on experience with enterprise networking:

  • DNS, SSL/TLS, load balancers, routing and firewall configuration

• Experience working in on-prem or hybrid environments

• Strong Bash or Python scripting for automation and maintenance

• Skilled in system-level monitoring, log analysis, and performance tuning

• Familiarity with VMware virtualization

Nice-to-Have

• Exposure to DevOps or infrastructure-as-code tools (e.g., Ansible, Terraform, Git, Jenkins)

• Experience with hybrid cloud setups (e.g., AWS, Azure), though not core to the role

• Understanding of security tools and practices, such as multi-factor authentication, data encryption, etc.

• Previous experience supporting IS Operations or enterprise platforms

What We're Looking For

• A self-starter who takes ownership of systems and delivers results independently

• A problem-solver who thrives in lean teams with hands-on responsibilities

• Someone who values clarity and documentation

• A strong communicator who collaborates well with both technical and non-technical stakeholders

This is an opportunity to join a technically challenging project environment with the freedom to own infrastructure and influence systems from the ground up. If you're an engineer who enjoys solving deep platform-level challenges and working across Linux systems and networks, this is the role for you.
