Your journey

We are seeking an experienced Senior Infrastructure/System Engineer to help operate, maintain, and improve our on-premise infrastructure environment. You will work hands-on with Linux systems, Kubernetes, RabbitMQ, Redis, and Elasticsearch, ensuring that our platforms are secure, scalable, and highly available.

This role is ideal for a technically driven engineer who thrives in complex, production-grade infrastructure environments and enjoys optimizing systems for reliability and performance.

Key Responsibilities:

  • Manage and enhance Kubernetes clusters, including configuration, upgrades, scaling, and deployment automation using Helm and Docker.
  • Operate, maintain, and optimize Linux-based systems in an on-premise datacenter environment.
  • Manage, monitor, and troubleshoot RabbitMQ clusters, ensuring message delivery reliability, scalability, and fault tolerance.
  • Administer and optimize Redis, Elasticsearch, and MySQL databases for performance, stability, and data integrity.
  • Support and execute database migration and infrastructure modernization projects within the on-prem environment.
  • Implement and maintain infrastructure-as-code practices using Terraform, Ansible, and GitLab CI/CD.
  • Maintain and improve monitoring, logging, and alerting systems (e.g., Prometheus, Grafana, Zabbix, ELK).
  • Collaborate with development and product teams to support deployment pipelines and performance optimization.
  • Participate in incident response, root cause analysis, and on-call rotations to ensure system reliability.
  • Ensure all systems meet security and data protection requirements.

*Qualifications:*

  • 5+ years of hands-on experience in system or infrastructure engineering, focused on on-premise environments.
  • Strong expertise in Linux system administration (Debian/Ubuntu or RHEL/CentOS).
  • Deep understanding of RabbitMQ, including clustering, high availability, performance tuning, and troubleshooting.
  • Experience managing and optimizing Redis and Elasticsearch in production.
  • Solid practical knowledge of Kubernetes, Docker, and Helm, including cluster management, deployments, upgrades, and troubleshooting.
  • Experience with infrastructure automation and configuration management using Terraform, Ansible, and GitLab CI/CD.
  • Strong understanding of networking, including routing, firewalls, VPNs, and secure access.
  • Experience with monitoring and observability tools (Prometheus, Grafana, Zabbix, ELK).
  • Excellent problem-solving and analytical skills, with attention to performance, reliability, and maintainability.
  • Familiarity with cloud providers such as AWS would be a plus.

*Preferred Qualifications:*

  • CKA (Certified Kubernetes Administrator) certification.
  • Experience managing RabbitMQ, Redis, Elasticsearch, and MySQL at scale in production environments.
  • Experience working with high-availability and distributed on-prem systems.
  • Familiarity with container security and system hardening best practices.
  • Knowledge of disaster recovery and business continuity planning for on-prem environments.
