The Opportunity

We're looking for a Security Engineer to join our Security Intelligence Team to achieve our ambitious goals. This role will contribute to our Security Intelligence team as an experienced, hands-on practitioner across offensive security, threat intelligence, threat hunting, and detection engineering.

You'll conduct research across security domains and automation technologies, identifying opportunities to enhance our capabilities through cutting-edge approaches and intelligent automation. Finally, you'll bring an attacker mindset into Grammarly's engineering and security culture, bridging the gap between offensive operations and defensive capabilities while driving forward our automation-first security approach.
