📋 Description

• Design and operate firewall, segmentation, and zero-trust controls across data center, corporate, and cloud (AWS) networks. • Build and maintain network security infrastructure as code — including firewall rules, policy automation, and CI/CD-driven deployment. • Lead network lifecycle management: design review, configuration baselines, change automation, and ongoing rule hygiene. • Build detection capabilities for network-based attacker behaviors and partner with the Detection & Response team on response playbooks. • Implement and operate network access controls including ZTNA, VPN, and remote access patterns. • Drive periodic firewall rule reviews, segmentation audits, and remediation campaigns to reduce risk and complexity. • Document network security architecture, controls, and operating procedures in clear runbooks.

🎯 Requirements

• Master's degree or higher in computer science. • Deep expertise with industry leading firewalls, including policy design, automation, and operations. • Strong proficiency with infrastructure as code (Terraform, Ansible) and at least one scripting language (Python preferred). • Hands-on experience operating network controls in a major cloud environment (AWS preferred), including VPCs, transit gateways, security groups, and cloud-native firewalls. • Practical understanding of ZTNA, segmentation, and modern network access patterns. • Solid fundamentals in TCP/IP, routing, switching, DNS, and TLS — with the ability to troubleshoot across the stack. • Excellent written communication skills, with the ability to create clear documentation for both engineers and operators.

🏖️ Benefits

• People who are serious about software make their own hardware. • Build a breakthrough AI platform beyond the constraints of the GPU. • Publish and open source their cutting-edge AI research. • Work on one of the fastest AI supercomputers in the world. • Enjoy job stability with startup vitality. • Simple, non-corporate work culture that respects individual beliefs.
