Who We’re Looking For

We’re looking for a System Administrator to own the servers, network and database layer that payment platform runs on. This is hands-on infrastructure work: keeping high-availability systems up, fast and secure, from the operating system and firewall up to MySQL clusters and the web tier.

Position Overview

As a System Administrator you will manage and maintain the servers, databases, networks, and security infrastructure supporting our global payment platform. You will ensure high availability, security, performance, and reliability while working closely with the DevOps team on infrastructure and platform operations.

Key Responsibilities

• Keep our high-availability server infrastructure healthy: monitoring, capacity planning and performance tuning.
• Administer Linux and BSD servers: provisioning, hardening, patching and upgrades.
• Run the database layer: highly available MySQL-family clusters, including replication, backups, restore tests, and query and server tuning.
• Manage network and perimeter security: host and network firewalls, intrusion prevention, and L4/L7 load balancers and proxies.
• Configure and tune the web and application tier: Nginx and the runtimes behind our polyglot backend (PHP, Go, Node.js and more).
• Maintain and regularly test backup and disaster-recovery procedures.
• Apply PCI DSS controls in day-to-day work: access management, logging, patch timelines and network segmentation.
• Set up servers and infrastructure for new company projects.
• Respond to incidents, find root causes and write them up. Take part in a shared on-call rotation.

Qualifications

• Bachelor’s degree in Computer Science, Information Technology or a related field, or equivalent practical experience.
• 5+ years administering Linux servers in production.
• Advanced MySQL / MariaDB / Percona: performance tuning, replication and troubleshooting under load.
• Hands-on experience running multi-node or clustered database setups (e.g. Galera, group replication).
• Firewall and network security experience on Linux and/or BSD (e.g. iptables/nftables, pf/ipfw,fail2ban).
• Working knowledge of load balancers and proxies (e.g. HAProxy, LVS/IPVS, database proxies).
• Nginx configuration and tuning, and running application runtimes in production (PHP-FPM, Go,Node.js or similar).
• Solid Bash scripting.
• Monitoring with Prometheus and Alertmanager.
• Strong written and spoken English (B2 or higher).

Nice to have

• FreeBSD or other BSD administration: a strong plus.
• PCI DSS experience in a cardholder-data environment.
• Ansible for configuration management.
• Python scripting.
• Docker and basic Kubernetes.
• Google Cloud Platform (GCP).
• Experience in payments, fintech or other regulated, high-availability environments.
• Using AI assistants (Claude, ChatGPT, Copilot, etc.) for scripting and troubleshooting, and checking their output before it touches production.
