Full Job Description

The Senior Linux Engineer is responsible for the design, implementation, maintenance, and optimisation of Linux-based systems that support the organisation’s IT infrastructure. This role plays a critical part in ensuring the availability, security, and performance of Linux environments essential to core business operations.

As the senior Linux Engineer, you will collaborate with cross-functional teams to manage system configurations, automate workflows, resolve technical issues, improve system reliability and its security. Your contributions will also include enhancing system architecture, applying security best practices, overseeing patch management, and driving continuous improvement initiatives.

This role requires advanced expertise in Linux system administration, scripting, and automation tools, coupled with a proactive, solution-oriented mindset focused on system efficiency and operational excellence.

Key Responsibilities -

Develop infrastructure architectures that align with business objectives, ensuring scalability, reliability, and security.
Participate in technical design discussions and provide input on best practices.
Support capacity planning and forecasting to ensure infrastructure can scale with organisational growth.
Develop scripts and tools to automate provisioning, configuration, and management of infrastructure components (servers, storages and networks) using Infrastructure as Code (IaC)
Implement container technologies like Docker and orchestration platforms such as Kubernetes to manage deployment, scaling and maintenance.
Supporting enterprise Linux environments with strong secure coding practices (OWASP, secrets management, vulnerability remediation)
Support disaster recovery (DR), backup strategies, and high availability solutions to ensure business continuity.
Ensure infrastructure and platform services align with organisational security policies, audit requirements, and regulatory standards.
Maintain technical documentation, operational procedures, and architecture standards for infrastructure and platform environments.
Strong understanding of Linux security hardening, patch management, access control, SELinux, MFA integration, privileged access management, and compliance standards (ISO 27001, NIST, CIS benchmarks).

Qualifications, Skills and Experience Required:

Bachelor’s degree in Computer Science, Information Technology, or related field.
7+ years of hands-on experience managing, configuring, and troubleshooting Linux-based operating systems (e.g., RHEL, OEL, Debian)
Experience with Ansible for system automation and infrastructure as code (IaC). Experience with tools like Puppet, or Chef could also be considered
Hands-on experience with virtualization (KVM & some VMware) .
Experience using monitoring tools (Nagios, Zabbix, Prometheus, Grafana) and optimizing system performance.
Familiarity with cloud platforms (AWS, Azure, GCP) and hybrid cloud deployments, including cloud-based Linux systems.
Knowledge of Linux security hardening, patch management, access control, SELinux, and compliance standards (ISO 27001, NIST, CIS benchmarks).
Storage & Filesystem Management – Experience with LVM, RAID configurations, NFS, and other Linux storage technologies.
Experience working in DevOps environments with CI/CD pipelines (Jenkins, GitLab CI, ArgoCD) to support application deployment and system integration.
Experience of database management for MySQL, PostgreSQL, or NoSQL databases in Linux environments.
Experience working in enterprise-scale environments, supporting mission-critical Linux infrastructure
Scripting & Automation – Proficiency in Bash, Python, or other scripting languages to automate system tasks and deployments.
Server & Network Management – Strong understanding of networking protocols, DNS, firewalls, load balancers, and system security best practices.
Incident Response & Troubleshooting – Strong problem-solving skills to diagnose and resolve system failures, log analysis, and performance issues.
Collaboration & Documentation – Ability to work in cross-functional teams, document system configurations, and create technical guides for operational teams.
