[Hiring] Linux Administrator @Quadcode

Role Description

We’re looking for a Linux Administrator to join our Ops team — a team working at the intersection of infrastructure and software development, supporting applications built with PHP and Go.

The Ops team is responsible for keeping the infrastructure and services behind our products stable, secure and reliable in production. The team works across:

• Virtual machines
• Databases
• CI/CD
• Monitoring
• Automation
• Internal platform services such as Thanos, Prometheus, Grafana, Ceph and profiling systems

Our infrastructure includes:

• 2,000+ virtual machines
• 500+ physical servers

We work with Scrum, Agile and a data-driven approach, with two-week sprints and a strong focus on continuous improvement.

The position is full-time remote, with a flexible start time — anytime before 12:00 pm EET/EEST.

Why this role?

• You won’t be focused on just maintaining servers or working with isolated infrastructure components.
• You’ll be part of the team responsible for the production environment behind products used by millions of users.
• You will work directly with development teams, helping them troubleshoot infrastructure-related issues and keep their services running reliably in production.
• It’s a good fit for an engineer who enjoys troubleshooting, automation and making infrastructure more reliable and scalable, rather than simply maintaining servers.

Qualifications

• 3+ years of hands-on experience administering Linux servers in production environments.
• Strong practical knowledge of Linux internals, networking, system services and troubleshooting.
• Experience administering PostgreSQL and/or Greenplum.
• Experience with containerization and orchestration technologies, including Docker and Kubernetes.
• Hands-on experience with Ansible for infrastructure automation.
• Good scripting skills with Python and/or Bash.
• Hands-on experience with CI/CD, particularly GitLab CI and/or Jenkins.
• Experience with monitoring, logging and system profiling, particularly Prometheus and Grafana.
• Fluent Russian (C2 or higher) for communication with the team.
• English B1+ for technical documentation and written communication.

Requirements

• DBA experience, including hands-on administration of databases and data infrastructure.
• Experience with Patroni.
• Experience supporting high-load or distributed production systems.
• Experience with AWS and OpenStack.
• Experience with PCI DSS.
• Experience reading and/or writing code in PHP/Go.
• Experience with Chef.
• Experience with fintech/trading.

Benefits

• Full-time remote work (service provider contract).
• Competitive compensation (EUR).
• Flexible working hours.
• Corporate AI subscriptions (Claude, Gemini, GPT, etc.).
• Access to a rewards marketplace offering products and language courses, redeemable using the company’s internal currency.
• A strong team of engineers.
• Positive and friendly atmosphere.
