You'll work closely with our exploit developers and threat researchers to ensure they have reliable, secure, and reproducible environments for testing against real-world hardware and software.

Manage lab network architecture - including segmentation, VLANs, out-of-band management, and isolated test environments to safely run exploit code against live devices.
Maintain firmware libraries and device inventories, ensuring researchers have access to specific hardware and software versions needed for vulnerability analysis.
Collaborate with researchers to understand upcoming research targets and proactively prepare the lab environments they need.
Manage vendor relationships for hardware procurement, warranties, and RMA processes.
Document lab architecture, procedures, and runbooks to ensure operational continuity.

Requirements

8+ years of experience in systems administration, lab operations, or infrastructure engineering.
Strong hands-on experience with Linux system administration (Ubuntu, CentOS/RHEL, or similar) install and ownership.
Experience managing and configuring networking equipment (Cisco, Juniper, MikroTik, etc), must have physical firewall and network switching experience..
Experience with virtualization and containerization technologies (VMware, Proxmox, KVM, Docker).
Experience with configuration management and infrastructure-as-code tools (Ansible, Terraform, or similar).

Prior experience supporting a security research, penetration testing, or red team lab environment.
Prior cybersecurity work experience (at a vendor or in government).
