Job Description

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 Infrastructure team, responsible for building, operating and continuously improving a private cloud infrastructure based on OpenStack and Kubernetes.

Our infrastructure supports the stable operation of a large-scale trading platform and includes 2,000+ virtual machines and 500+ physical servers, as well as a wide range of Linux systems and infrastructure services such as DNS, GitLab, Artifactory, Prometheus, Loki and Vault.

You’ll work in a team of experienced infrastructure engineers, using Scrum and Agile practices, with two-week sprints and a strong focus on automation, reliability and continuous improvement.

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

Why this role?

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.

Tasks

• Oversee various services and associated infrastructure components, including DNS, Gitlab, Artifactory, Vault, etc;
• Perform day-to-day operational tasks such as upgrades, CVE patching, backup and restore, security scans, and monitoring;
• Manage and support private clouds (Openstack and Kubernetes);
• Design, configure, maintain and troubleshoot Linux systems across different environments, including bare metal, virtual machines and containers.
• Resolve incidents, provide support coverage, categorize issues, conduct post-mortems, and perform root cause analysis;
• Ensure environments are stable and adhere to availability SLAs;
• Work towards reducing operational effort;
• Automate repetitive operational tasks and continuously reduce manual effort;
• Collaborate with development teams to troubleshoot infrastructure-related issues in production;
• Keep infrastructure documentation and operational procedures up to date;
• Engage in constant upskilling to stay updated with industry best practices.

Requirements

Nice to have

• Hands-on experience with Kubernetes, including troubleshooting workloads and cluster-related issues.
• Hands-on experience with OpenStack, including deployment, configuration, maintenance or troubleshooting of private cloud environments.
• Experience with GitLab CI/CD, Jenkins or GitHub Actions.
• Experience working with fintech/trading, or other high-load and mission-critical systems.

We offer

With a team of 500+ creative and tech-driven people across the globe, Quadcode is the place where ideas turn into impact, where every project is a chance to grow, innovate, and make your mark.

Join us today, and let's shape the future of fintech together!
