Linux Administrator (Ops)

About the Team

We are Quadcode, a fintech company excelling in financial brokerage activities and delivering advanced financial products to our global clientele. Our flagship product, an internal trading platform, is offered as a Software-as-a-Service (SaaS) solution to other brokers.

About the role 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 and internal platform services such as Thanos, Prometheus, Grafana, Ceph and profiling systems. Our infrastructure supports the stable operation of a large-scale trading platform and includes 2,000+ virtual machines and 300+ physical servers, running predominantly on Ubuntu. 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, working 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.
