Infrastructure Engineer

Описание

Responsibilities

• You
• Build, maintain, and optimize server and network infrastructure
• Configure and maintain VPNs, private networks, routing, firewalls, and secure connectivity between infrastructure components
• Manage infrastructure across AWS, Hetzner, and dedicated/bare-metal environments
• Automate provisioning and configuration
• Improve infrastructure reliability, performance, fault tolerance, and security
• Optimize systems for performance-sensitive trading workloads
• Build and improve monitoring, observability, and alerting
• Evaluate new technologies, providers, hardware, and architectural approaches
• Work closely with developers and the trading team to understand where infrastructure can improve the performance of the overall trading stack

Requirements

• Hands-on experience setting up Kubernetes on bare metal (Hetzner, private DCs, or similar) — not just managed clusters like EKS/GKE
• Solid command of Prometheus, Grafana, and a logging stack (Loki / ELK / equivalent)
• Production experience with both Ansible and Terraform
• CI/CD pipeline design for container images (GitLab CI / GitHub Actions / ArgoCD / similar)
• Understanding of ML infrastructure specifics: GPU nodes, job queues, large datasets, long-running jobs
• Ability to read and assess legacy infrastructure code and make pragmatic decisions about what to reuse vs. rewrite
• Independence — this is a sole-infrastructure role on the project

Nice to have

• Experience with trading/HFT infrastructure, low-latency systems, advanced networking, bare-metal optimization, or high-performance computing would be a strong advantage
• VPN setup, network policies, secrets management (Vault)
• Familiarity with ML tools

We offer

• Office-based work in Limassol, Cyprus, working closely with the core team
• Full ownership of the infrastructure — you’ll have the freedom to shape, improve, and rethink the systems you work with
• Real engineering freedom — propose new tools, providers, hardware, network setups, automation, or architectural changes if you believe there’s a better way
• Challenging trading infrastructure — work with performance-sensitive systems, dedicated servers, networking, and infrastructure where speed, reliability, and efficiency actually matter
• Direct impact — infrastructure improvements can directly affect the performance and reliability of our trading systems
• Competitive compensation, based on your experience and technical level
