• Develop and implement infrastructure standards, patterns, and best practices for lab deployment.
• Optimize lab performance and resource utilization for thousands of concurrent users, including workspace-based and private lab sessions.
• Lead infrastructure migrations, cost optimization initiatives, and high-availability implementations.
• Implement automation using Infrastructure-as-Code tools (Terraform, Ansible) and create self-service capabilities for teams.
• Establish observability, monitoring, logging, and disaster recovery procedures to maintain uptime and performance.
• Design network architectures, including VPNs, VLANs, software-defined networking, and security controls appropriate for vulnerable lab environments.
• Collaborate with cross-functional teams, provide mentorship, and contribute to architectural reviews and process improvements.

• 4+ years of experience in SRE, Site Reliability Engineering, or Infrastructure Architecture roles.

• Production experience with OpenStack and hybrid cloud platforms (AWS, Azure, GCP).
• Advanced knowledge of Linux and Windows Server environments.
• Expertise in networking, including TCP/IP, routing protocols, VPNs, firewalls, and network security.
• Proficiency in Infrastructure-as-Code tools (Terraform, CloudFormation, ARM templates) and configuration management.
• Experience with containerization and orchestration (Docker, Kubernetes).
• Proven track record in large-scale distributed systems design, high availability, disaster recovery, and cost optimization.
• Strong strategic thinking, analytical problem-solving, and proactive approach to infrastructure challenges.
• Excellent communication and leadership skills, with experience mentoring engineers and driving technical standards adoption.
• Background in cybersecurity, penetration testing, or vulnerability research environments is a plus.

• Competitive compensation and flexible work arrangements.
• Fully remote work with flexible hours.
