We are looking for: A Cyber Range Engineer who will architect, deploy, and maintain cloud-based cyber ranges and training environments. You will be responsible for designing and implementing scalable, realistic training infrastructure that emulates enterprise environments across multiple cloud platforms. Working alongside security researchers and training specialists, you'll create the technical foundation that enables high-fidelity security simulations and exercises. As a Cyber Range Engineer, you will ensure our ranges provide authentic cloud experiences while maintaining isolation, monitoring capabilities, and resource efficiency.

What will you be doing as a Cyber Range Engineer?

• Design, implement and maintain local and cloud-based cyber range architectures that support multiple concurrent training scenarios and user sessions
• Develop automation frameworks for rapid deployment, teardown, and reset of range environments using Infrastructure as Code (IaC) principles
• Create emulated cloud services and resources when direct cloud integration isn't feasible or cost-effective
• Maintain security controls and network isolation to prevent range escape or resource abuse
• Be an expert on Sim Space software providing guidance and documentation for many different use cases
• Develop and maintain documentation for range architectures, deployment procedures, and troubleshooting guides
• Occasional travel to other customer or partner locations (estimated 10%) may be required in the future

What are the qualifications to apply? To be successful as a Cyber Range Engineer, you need to have:

• Expertise in networking knowledge including:
  • Virtual networking architecture and segmentation subnets, routing)
  • Network security and access control (firewalls, security groups, NACLs)
  • Secure connectivity solutions (VPN and direct…
