Job description

Network & Infrastructure Security Analyst (AI Training)

About The Role

We partner with the world's leading AI research labs to build smarter, more capable AI systems — and we need real security practitioners to make it happen. As a Network & Infrastructure Security Analyst, your hands-on experience with firewalls, EDR, SIEMs, and enterprise environments will directly shape how AI understands and reasons about cybersecurity threats.

This is a unique opportunity to move beyond reactive incident response and contribute to something bigger: building the security intelligence layer inside next-generation AI.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

What You'll Do

• Analyze realistic network, endpoint, and email security scenarios drawn from modern enterprise environments
• Review firewall logs, EDR alerts, and infrastructure security cases to determine root causes and failure points
• Classify incidents, misconfigurations, and control failures based on real operational data
• Create, label, and validate security training datasets used to improve AI reasoning and response quality
• Clearly explain security issues, their root causes, and business impact in structured formats

Who You Are

• 2+ years of hands-on experience in network, infrastructure, or endpoint security roles
• Solid familiarity with firewalls, EDR platforms, email security, IAM, SIEMs, and enterprise tooling
• Strong understanding of how real organizations deploy and operate security controls at scale
• Able to communicate complex security concepts clearly and concisely in writing
• Self-directed and comfortable working asynchronously on task-based assignments

Nice to Have

• Experience with threat hunting, incident response, or red/blue team operations
• Background in security architecture, cloud security, or zero-trust environments
• Familiarity with AI or data annotation workflows

Why Join Us

• Work directly on frontier AI systems alongside top security and research teams
• Fully remote and flexible — work on your schedule, from anywhere
• Freelance autonomy with meaningful, intellectually engaging work
• Contribute to AI that will help defend real organizations against real threats
• Potential for ongoing work and contract extension
