About the roleWe’re looking for a hands-on Cybersecurity Lab Designer to build realistic, reliable training environments. You’ll design Linux-based machines and multi-host labs, including Active Directory environments, interconnected attack paths, and standalone challenges. You’ll work with our security team to turn learning objectives into safe, reproducible labs.

What you’ll do

- Design and build Linux machines for cybersecurity training.
- Create standalone challenges and interconnected environments with realistic networks, services, users, and attack paths.
- Build Active Directory labs involving Linux systems and services integrated with Windows domains.
- Develop scenarios covering reconnaissance, initial access, privilege escalation, lateral movement, and remediation.
- Create repeatable build and reset processes using scripts, configuration management, or infrastructure-as-code tools.
- Test labs for functionality, difficulty, stability, and clear learning outcomes.
- Write setup notes, hints, objectives, and solution documentation.
- Work with other designers and reviewers to improve lab quality.

What we’re looking for

- Strong Linux administration skills, including networking, services, permissions, logging, and troubleshooting.




- Practical knowledge of Active Directory concepts and Linux integration with AD, including protocols such as LDAP, Kerberos, and SMB.
- Experience building multi-machine environments and understanding trust boundaries, routing, and segmentation.
- Proficiency in scripting with Bash and Python; familiarity with PowerShell is helpful.
- Experience with virtualization or lab platforms such as Proxmox, VMware, VirtualBox, KVM, or cloud environments.
- Ability to build realistic scenarios while keeping environments isolated and secure.
- Clear technical writing and an ability to explain the intended learning path.

Nice to have

- Experience designing CTF, cyber range, or penetration-testing training labs.
- Familiarity with Docker, Terraform, Ansible, Packer, or similar automation tools.
- Knowledge of common Linux and Active Directory attack techniques and defensive mitigations.
- Experience balancing challenge difficulty, reproducibility, and learner experience.
