We are looking for a DevOps Engineer to join our high caliber team.

The Role

We are seeking an experienced DevOps Engineer to design, automate, and continuously improve our modern, high-availability infrastructure. Our environment is built on open-source technologies and cloud-native practices, with a strong emphasis on reliability, observability, and scalable deployments. You will be a key contributor in bridging the gap between development and operations, ensuring our platforms run efficiently and resiliently at scale..

Your contribution to the success of the team

  • Design and manage robust, high-availability Linux-based infrastructure (Ubuntu), ensuring uptime, performance, and security across production environments.
  • Configure and maintain web infrastructure and reverse proxy solutions using Nginx, including load balancing, SSL termination, and traffic routing.
  • Administer and optimize relational databases (MySQL / MS SQL), including performance tuning, backup strategies, and high-availability configurations.
  • Automate infrastructure provisioning and configuration using Ansible, driving consistency and repeatability across environments.
  • Build, maintain, and improve CI/CD pipelines using GitLab CI and/or Jenkins, enabling fast, reliable, and automated software delivery workflows.
  • Manage containerized workloads using Docker, including image building, registry management, and container lifecycle operations.
  • Orchestrate and scale containerized applications with Kubernetes, managing deployments, services, ingress, autoscaling, and cluster health.
  • Implement and maintain monitoring and alerting systems using Prometheus and Grafana, ensuring full visibility into system health and proactive incident detection.
  • Manage centralized logging, troubleshooting, and data analysis using the ELK Stack (Elasticsearch, Logstash, Kibana), enabling fast root cause analysis and operational insights.
  • Collaborate closely with development, security, and product teams to support deployments, resolve incidents, and continuously improve platform reliability.
  • Champion DevOps culture by promoting automation-first thinking, documentation, and continuous improvement practices across the engineering organization.

Your Qualifications & Competencies

  • 3+ years of experience in a DevOps, Infrastructure, or SRE role in a production environment.
  • Strong Linux administration skills (Ubuntu), including system configuration, performance tuning, networking, and security hardening.
  • Solid understanding of networking fundamentals — DNS, TCP/IP, HTTP/S, load balancing, firewalls, and VPNs.
  • Hands-on experience with CI/CD tools (GitLab CI, Jenkins, or equivalent) and a deep understanding of automated delivery workflows.
  • Proficiency with Docker — image creation, multi-stage builds, Docker Compose, and container security best practices.
  • Working experience with Kubernetes — deployments, services, ConfigMaps, Secrets, Helm charts, and cluster operations.
  • Experience with configuration management and automation using Ansible or similar tools.
  • Familiarity with monitoring and observability stacks — Prometheus, Grafana, and ELK (Elasticsearch, Logstash, Kibana).
  • Database administration experience with MySQL and/or MS SQL, including query optimization and backup/recovery procedures.
  • Strong troubleshooting skills in production systems, with the ability to perform root cause analysis under pressure.
  • Fluent in English.

Nice to Have

  • Experience with cloud platforms (Microsoft Azure preferred) and cloud-native architectures.
  • Knowledge of Infrastructure as Code (IaC) tools such as Terraform or Bicep.
  • Familiarity with service mesh technologies (Istio, Linkerd).
  • Experience with GitOps workflows (ArgoCD, Flux).
  • Understanding of security best practices in DevOps (DevSecOps), including secrets management and vulnerability scanning.
  • Relevant certifications (e.g., CKA/CKAD, Azure DevOps Engineer Expert, AWS DevOps Professional).
  • Passion for open-source technologies and active engagement with the community.
