DevOps & Cloud Infrastructure Engineer

Birrama Digital Commerce PLC is seeking a hands-on, highly skilled DevOps & Cloud Infrastructure Engineer to manage, secure, automate, and continuously scale the company's technology infrastructure. Working across Linux operating systems, local/private and public cloud platforms, networking, containerized workloads, Kubernetes, CI/CD pipelines, and observability stacks, this role ensures production environments remain secure, highly available, and reliable. Strong practical expertise in on-premises/private cloud infrastructure, production Linux administration, and container orchestration is core to this position.

1. Operating Systems, Systems Administration & Networking

• Administer, patch, and maintain production Linux distributions (Ubuntu, RHEL, Alpine Linux).

• Manage system users, access controls, permissions, package dependencies, and server performance optimization.

• Configure and troubleshoot networking protocols, including DNS, TCP/IP, HTTP/HTTPS, SSH, and SSL/TLS certificate management.

• Maintain firewall rules, network access controls, routing, and secure remote management access.

2. Cloud Infrastructure, Storage & Virtualization

• Deploy, maintain, and scale virtual machines and compute resources across local/private cloud and public cloud platforms.

• Configure and administer object storage platforms (S3-compatible, Google Cloud Storage, Azure Blob Storage).

• Design and manage Virtual Private Clouds (VPCs), subnets, NAT gateways, load balancers, and IAM access policies based on the principle of least privilege.

• Support backup, disaster recovery (DR), business continuity, and maintain strict isolation between dev, staging, and production environments.

3. Containerization, Kubernetes & Orchestration

• Build, optimize, and secure Docker images using multi-stage builds and container vulnerability scanning.

• Deploy and manage Kubernetes (K8s) workloads (Pods, Deployments, StatefulSets, Ingress Controllers, ConfigMaps, Secrets, Persistent Volumes).

• Manage application deployments and release configurations using Helm charts.

• Troubleshoot deployment failures, pod errors, resource limits, and network bottlenecks within containerized clusters.

4. CI/CD, Automation & Infrastructure Management

• Maintain source code repositories and version control workflows in Git (GitHub, GitLab, Bitbucket).

• Design, automate, and optimize CI/CD pipelines using GitHub Actions, GitLab CI/CD, Jenkins, and GitOps tools (ArgoCD).

• Manage deployment secrets, environment variables, and rollback procedures safely across environments.

• Automate repetitive infrastructure and operational tasks.

5. Monitoring, Observability & Incident Response

• Implement continuous monitoring, alerting, and operational dashboards using Prometheus, Grafana, Datadog, or New Relic.

• Establish centralized log aggregation and tracing stacks (ELK Stack, Fluentd/Fluent Bit, CloudWatch, GCP Cloud Logging).

• Investigate production incidents using metrics, logs, and traces; conduct root-cause analysis (RCA) and implement preventive measures.

6. Infrastructure Security, Reliability & Documentation

• Apply security best practices across Linux OS, networks, cloud resources, containers, and Kubernetes environments.

• Maintain complete documentation for infrastructure architecture, runbooks, operational guides, and recovery procedures.

• Collaborate closely with software development teams to enhance deployment pipelines, environment consistency, and system performance.

• Bachelor's Degree in Computer Science, Software Engineering, Information Technology, Computer Engineering, Information Systems, or a closely related technical field.

• Demonstrated hands-on experience in DevOps, Cloud Engineering, Systems Administration, Site Reliability Engineering (SRE), or Infrastructure Engineering.

• Proven experience administering production Linux environments and networking infrastructure.

• Practical experience deploying containerized applications, managing Kubernetes clusters, and building automated CI/CD pipelines.

• Direct experience managing private/local cloud or virtualized infrastructure is highly preferred.

• Operating Systems & Scripting: Strong command of Linux administration (Ubuntu, RHEL, Alpine), bash scripting, package management, and system troubleshooting.

• Networking & Security: Practical knowledge of TCP/IP, DNS, HTTP/HTTPS, SSH, SSL/TLS, firewalls, VPCs, subnets, routing, and IAM principles.

• Containers & Kubernetes: Hands-on experience with Docker, multi-stage builds, Kubernetes workloads, Ingress, and Helm charts.

• CI/CD & Automation: Proficiency with Git, GitHub Actions, GitLab CI/CD, Jenkins, or GitOps (ArgoCD).

• Monitoring & Observability: Experience setting up Prometheus, Grafana, ELK Stack, or Fluentd for centralized logging and metrics.

• Troubleshooting: Analytical problem-solving skills for debugging production incidents, performance bottlenecks, and infrastructure faults.

• Certifications: CKA/CKAD (Kubernetes), RHCSA/RHCE (Linux), AWS, Azure, GCP, or networking/security certifications.

• Infrastructure as Code (IaC): Hands-on experience with Terraform or OpenTofu.

• Configuration Management: Experience with Ansible, Puppet, or Chef.

• Database Infrastructure: Experience with database cluster deployment, backup, and restore procedures.
