Job details

Network & Infrastructure Security Analyst (AI Training) About The Role We're partnering with the world's leading AI research labs to build smarter, safer security intelligence — and we need practitioners who've lived it in the real world. As a Network & Infrastructure Security Analyst, you'll analyze real-world enterprise security scenarios — firewall events, EDR alerts, email threats, and infrastructure misconfigurations — and use your hands-on experience to help train and evaluate cutting-edge AI systems. Your expertise directly shapes how AI understands, reasons about, and responds to cybersecurity threats. This is a remote, flexible contract role ideal for experienced security professionals looking to contribute to frontier AI while working on their own schedule. Organization: Alignerr Type: Hourly Contract Location: Remote Commitment: 10–40 hours/week What You'll Do Analyze network, endpoint, and email security scenarios across modern enterprise environments Review firewall, EDR, SIEM, and infrastructure security cases to determine what went wrong and why Classify incidents, misconfigurations, and control failures based on realistic operational data Create, label, and validate security training and evaluation datasets used to improve AI systems Clearly articulate root causes, attacker techniques, and business impact in structured formats Work independently and asynchronously on task-based assignments Who You Are 2+ years of hands-on experience in network, infrastructure, or endpoint security roles Familiar with enterprise security tooling: firewalls, EDR platforms, email security gateways, IAM, and SIEMs Strong understanding of how real organizations deploy, operate, and fail at security controls Able to communicate complex security issues clearly — not just identify them, but explain them Detail-oriented with a systematic approach to analysis Self-motivated and comfortable working remotely without close supervision Nice to Have Experience with threat hunting, incident response, or security operations Familiarity with frameworks like MITRE ATT&CK, NIST, or CIS Controls Background in red team, blue team, or purple team activities Prior experience contributing to AI, data labeling, or security research projects Why Join Us Work directly on frontier AI systems with top-tier research labs Fully remote and flexible — work when and where it suits you Freelance perks: autonomy, variety, and meaningful contribution to AI safety Put your real-world security knowledge to use in a uniquely impactful way Potential for ongoing work and contract extension

What you’ll do

Analyze enterprise network, endpoint, email, and infrastructure security scenarios to identify incidents, misconfigurations, control failures, root causes, attacker techniques, and business impact. Create, label, and validate structured security datasets for training and evaluating AI systems.

Requirements

Requires at least two years of hands-on experience in network, infrastructure, or endpoint security, along with familiarity with enterprise firewalls, EDR, email security gateways, IAM, and SIEM tools. Candidates should understand how organizations operate security controls, communicate findings clearly, and work independently; threat hunting, incident response, security frameworks, or AI data-labeling experience are advantageous.
