Senior Infrastructure & Security Engineer
The Role
We are looking for a sharp, security-minded Infrastructure Engineer to help us build out a high-performance colocation environment and keep it locked down.
We’re deploying a mix of bare-metal Linux servers and high-density NVIDIA GPU nodes. Because we handle enterprise workloads, security is our top priority. We need someone who knows physical hardware, network engineering, and system hardening inside out.
What You’ll Do

Hardware Setup: Rack, cable, network, and provision physical bare-metal servers and GPU nodes in our colocation space.
System Hardening: Build strict defense-in-depth security—firewalls, segmented VLANs, zero-trust access, SSH hardening, and OS-level security policies.
Secure Self-Hosted Tools: Harden and manage our internal tools (GitHub Enterprise, Nextcloud, chat, n8n, etc) and client environments.
Monitoring & Backups: Set up log auditing, SIEM/intrusion detection, real-time alerts, and automated offsite backups.

What We Need

Bare-Metal & Datacenter Skills: True sysadmin/datacenter experience—L2/L3 networking, IPMI/iDRAC, switch configuration, RAID, and Linux OS deployment.
Security Mindset: You treat security as a baseline, not an afterthought. Deep knowledge of network isolation, VPNs (WireGuard/Tailscale), firewall policies, and system auditing.
Core Linux Admin & Automation: Master-level Linux skills (Ubuntu/Debian/RHEL, systemd, storage, bash scripting) alongside Infrastructure as Code (Ansible, Terraform) for bare-metal OS provisioning and automated config management.
Hands-On & Reliable: You like working with real hardware and take pride in running clean, stable, highly secure systems.

Nice-to-Haves

Compliance: Experience working under TISAX, SOC 2, or ISO 27001 standards.
Tooling Integration: Familiarity with hosting n8n or LiteLLM gateways securely.
AI Hardware: Prior experience managing NVIDIA GPU drivers, CUDA environments, and enterprise GPU nodes.
