Job description

Linux Infrastructure Engineer

Location: Johannesburg working Hybrid

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.
