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 Were 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
