Workplace Architect

Role Overview

• Install, administer, and maintain Linux operating systems, including Debian and RHEL distributions.
• Design, deploy, and maintain virtualisation environments (libvirt) and containerisation tools (LXC, Docker).
• Manage Kubernetes (K8s) clusters — deployments, services, scaling, and troubleshooting in production environments.
• Strong knowledge of networking protocols and services: IP, routing (static, OSPF, BGP), DNS, VPN, HA technologies (bridging, keepalive), firewalls, and Cisco Meraki.
• Design and maintain secure, high-availability network infrastructure across distributed environments.
• AWS: EC2, VPC, IAM, S3, RDS, EKS, CloudWatch, CloudTrail, Lambda. Experience with cost optimisation (Cost Explorer, Savings Plans) and security groups/policies.
• GCP: Compute Engine, GKE, Cloud Storage, Cloud SQL, VPC, IAM, and Cloud Monitoring. Familiarity with Terraform or similar IaC tools for cloud resource management.
• Experience managing multi-tenant cloud environments and migration projects (on-prem → cloud).
• Understanding of cloud security principles: encryption, secrets management (HashiCorp Vault, AWS Secrets Manager), Zero Trust networking.
• Configure and manage web servers: Nginx, Apache, PHP.
• Database administration with MySQL/MariaDB, including replication technologies (bin-log, Galera).
• Experience with Redis, Memcache, Supervisord, and Logstash.
• Infrastructure monitoring using Nagios, Zabbix, Grafana, Prometheus, and Netdata.
• Apply cybersecurity principles including vulnerability management, SIEM, and XDR.
• Certificate lifecycle management (PKI, Let's Encrypt) and vulnerability scanning.
• Infrastructure as Code using Terraform, Ansible, or Puppet.
• Scripting in Bash, Python, or similar languages to automate repetitive operational tasks.
• Experience with CI/CD pipelines (GitLab CI, GitHub Actions, or equivalent) is a plus.
• Create and maintain technical documentation, knowledge base articles, and runbooks — Atlassian Stack (Confluence, Jira).

Requirements

• Degree in Computer Science, Information Technology, or a related field — or equivalent practical experience.
• 5+ years of experience in Linux systems administration and IT infrastructure management.
• Proven hands-on experience with AWS and/or GCP in a production environment.
• Strong understanding of the technologies listed above.
• Excellent problem-solving skills with the ability to troubleshoot complex issues independently.
• Strong communication and interpersonal skills; ability to collaborate effectively across teams and with external stakeholders.
• Demonstrated ability to work independently and manage multiple priorities simultaneously.
• Relevant certifications are a strong plus: RHCE, CCNA, AWS Solutions Architect, GCP Associate Cloud Engineer, or equivalent.
• Fluent written and spoken English.
