This role will contribute to our D&R team as hands-on practitioner across incident response, detection engineering, threat hunting, and threat intelligence. You'll plan, execute, and debrief complex security operations, leveraging those insights to enhance our threat mitigation capabilities and build robust, automated security tooling across all Superhuman environments. Additionally, you'll own key workstreams in executing and advancing our security vision, translating strategic objectives into tactical implementations through strong technical execution and innovative solution building, with particular emphasis on automation and AI-powered security solutions. 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 Superhuman’s engineering and security culture, thinking like a threat actor to defend our systems in a way that is grounded in how real attacks happen. Superhuman's engineers and researchers have the freedom to innovate and uncover breakthroughs—and, in turn, influence our product roadmap. The complexity of our technical challenges is growing rapidly as we scale our interfaces, algorithms, and infrastructure. Curious how we build and operate our AI agents?
