Network & Infrastructure Security Analyst (AI Training)

About The Role

At Alignerr, we partner with the world's leading AI research teams and labs to build and train cutting-edge AI models. We're looking for experienced infrastructure and network security professionals to help us make AI smarter about how real-world security works.

Your hands-on knowledge of enterprise security — the tools, the failures, the edge cases — is exactly what's needed to evaluate and improve the next generation of AI-driven security systems. This is a unique opportunity to apply your practitioner expertise to frontier AI development, on your own schedule.

What You'll Do

- Review firewall, EDR, and infrastructure security cases to identify what went wrong, why, and what the business impact was

- Classify incidents, misconfigurations, and control failures based on real operational data

- Create, label, and validate security training and evaluation datasets used to improve AI systems

- Clearly articulate root causes, attacker techniques, and defensive gaps in a structured format

Who You Are





- 2 years of hands-on experience in network, infrastructure, or endpoint security

- Familiar with firewalls, EDR platforms, email security gateways, IAM systems, and SIEMs

- Strong understanding of how security controls are deployed and operated in real enterprise environments

- Able to explain complex security issues clearly — root causes, business impact, and remediation — in plain language

- Self-motivated, detail-oriented, and comfortable working independently and asynchronously

Nice to Have

- Experience in threat hunting, incident response, or red/blue team operations

- Familiarity with cloud security (AWS, Azure, GCP) or hybrid enterprise environments

- Background in writing security documentation, post-mortems, or runbooks

- Prior experience working with AI or data labeling workflows

Why Join Us

- Work directly on frontier AI systems alongside top-tier research labs

- Fully remote and flexible — complete tasks on your own schedule
