You'll work with a diverse set of modern technologies, including Linux, Kubernetes, Infrastructure as Code (IaC) tools, monitoring systems, and distributed databases.

This position offers the opportunity to work at the heart of a high-performance global platform, directly influencing its scalability, reliability, and resilience. You will collaborate with experienced engineers, shape best practices, and contribute to the continuous evolution of our infrastructure — ensuring that our systems remain robust, secure, and efficient at scale.

• Operate and support core infrastructure services such as Nginx, Puppet, GitLab, Artifactory, Nexus, Harbor, Grafana, etc.

• Manage and evolve infrastructure following the Infrastructure as Code (IaC) paradigm.

• Handle and resolve incidents related to infrastructure operations.

• Collaborate closely with cross-functional teams (network engineers, developers, and other technical stakeholders).

• Design and implement high-availability, fault-tolerant, and scalable software solutions.

• Monitor service performance and availability using modern observability tools, ensuring system reliability and optimal resource utilization.

WHAT WE ARE LOOKING FOR

• 4+ years of experience in Linux administration, DevOps, or Site Reliability Engineering (SRE).

• Strong proficiency in automating tasks using Bash or similar scripting languages.

• Solid understanding of networking fundamentals (TCP/IP stack, routing, DNS, etc.).

• Hands-on experience managing bare-metal infrastructure in production environments.

• Experience with configuration management systems such as Ansible or Puppet.

• Experience with distributed databases (Elasticsearch, Cassandra, MongoDB, MySQL, PostgreSQL, etc.).

• Expertise in Kubernetes administration and managing containerized workloads.

• Experience with IaC tools such as FluxCD or ArgoCD.

• Ability to design and implement high-performance, fault-tolerant, and secure infrastructure solutions.

• Experience with monitoring and observability systems — Zabbix, VictoriaMetrics, Loki, Grafana, etc. — including building dashboards and configuring alerting.

WHAT SETS YOU APART

• Programming experience in Python, Go

• Experience with cloud providers (AWS, GCP, Alibaba Cloud, or others).

• Familiarity with distributed storage systems (Ceph).

• Experience with service meshes (e.g., Istio).

• Proven track record of working on high-load, large-scale distributed systems.
