Note: The job is a remote job and is open to candidates in USA. Pragmatike is recruiting on behalf of a European deep-tech company developing a decentralized, energy-efficient alternative to traditional cloud providers. The SRE / Network Engineer will maintain and support core infrastructure systems, design scalable networks, automate operations, and manage observability stacks while working with advanced cloud technologies.

Responsibilities

• Maintain and support core infrastructure systems with deep knowledge of Linux (Debian/Ubuntu preferred)
• Work close to the metal: BIOS, IPMI, RAID setups, and hardware-level diagnostics are part of your comfort zone
• Design and maintain scalable networks using VLANs, L2/L3 routing, VPNs, and especially UniFi equipment
• Automate infrastructure provisioning and operations with Ansible, Bash/Python, and Git-based workflows
• Set up and manage observability stacks, including Prometheus/Grafana for metrics and Graylog, ELK, or Loki for log centralization
• Build tooling for server discovery, config auto-generation, automated OS deployments, PXE/Preseed/Cloud-init, and strong MAAS-based provisioning
• Integrate and/or develop internal APIs for tracking compute and GPU resource allocation, as well as external APIs (billing, monitoring, OpenStack, etc.)
• Deploy and maintain virtualization and orchestration systems such as OpenStack (preferably with Kolla-Ansible), Proxmox VE, or VMware ESXi
• Support container-based workloads and isolate services efficiently
