Senior Machine Learning Engineer

About us

Radiant Security is the maker of the industry’s first AI SOC Analyst, which uses Gen AI to emulate the experience, processes, and decision-making of top-tier security analysts. With Radiant, alerts are sent to our AI analyst before they go to the SOC. Each alert is subjected to dozens to hundreds of dynamically selected tests used to determine maliciousness. Within 3 minutes decision-ready results are available that include a detailed incident summary, root cause analysis, and an incident specific response plan. This means, by the time an analyst sees an incident they know if it was real, what happened, what caused it, and have a plan to fix it. After reviewing the report, analysts can respond manually using AI generated, step-by-step instructions on how to respond to this incident, using single-click responses which run over API connections to take corrective actions, or with fully automated response that runs without human intervention. With Radiant, SOC teams detect more attacks, respond more rapidly, and get more done.
