In this role, you will be an executive engineering leader with experience building massive-scale distributed data systems, driving high-reliability platform engineering, and advocating advanced security automation and agentic defense. You will bridge software engineering with cyber defense partnering closely with Detection and Response domain leads, and enterprise platform teams to transform Google’s security posture from reactive "Detect and Respond" to proactive "Infer and Interrupt". Additionally, you will manage, grow, and mentor a globally distributed organization of Software Engineering Managers, Tech Leads, and Software Engineers across multiple global sites. You will own the long-term architectural road map for the Detection and Response teams core infrastructure. You will lead the engineering and deployment of automated threat containment (e.g., automated mitigation pipelines, and dynamic endpoint mitigation) to disrupt high-risk access abuse, workspace DLP, and intrusion attempts in real-time. You will drive the integration of AI models and agentic reasoning into operational workflows, automating alert triage, incident summaries, and investigative workflows. You will ensure platform reliability, multi-region resilience, and SLO compliance, reducing operational toil and on-call burden to established target of engineering bandwidth. ## At a glance - Posted by the employer: Not stated - First seen by OpenNash: Oct 30, 2026 - Last checked: Oct 30, 2026 - Listed for: Under a day - Location: San Francisco, CA, USA +1 more[Apply on Alphabet’s careers site →](https://www.google.com/about/careers/applications/jobs/results/142285540920566470-director-security-defense-platforms) ## Hiring at Alphabet - Open jobs: 3,591 - New in the last 7 days: After two weekly collections - Tracked since: Aug 20, 2026 [All Alphabet jobs](https://jobs.opennash.com/companies/alphabet/) · [Weekly hiring report](/reports/hiring/) ## More jobs at Alphabet ### [AI Threat Defense Engineer, Google Cloud Consulting](https://jobs.opennash.com/companies/alphabet/jobs/ba28081fdcac4cd82141/) San Francisco, CA, USA +1 more ### [Brand Marketing Manager, AI Education, Consumer Apps Marketing](https://jobs.opennash.com/companies/alphabet/jobs/c4389ec72c61e83b1e17/) San Francisco, CA, USA +1 more ### [Customer Growth Associate, Google Customer Solutions (English)](https://jobs.opennash.com/companies/alphabet/jobs/ffb8cd2594b19712ce3f/) San Francisco, CA, USA +1 more ### [Customer Growth Associate, Google Customer Solutions, University Graduate, 2027 Start (English)](https://jobs.opennash.com/companies/alphabet/jobs/d80568b2483376e74f43/) San Francisco, CA, USA +1 more ### [Energy Strategic Negotiator, Power Generation Solutions](https://jobs.opennash.com/companies/alphabet/jobs/4a14fd22299b0950b4c5/) San Francisco, CA, USA +1 more ## Similar jobs at other companies ### [Director, Proactive Defense Operations](https://jobs.opennash.com/companies/gsk/jobs/3c4dc0d29b8880a5ace5/) GSK · Philadelphia, Pennsylvania, United States of America ### [Lead Software Engineer - Security Platforms](https://jobs.opennash.com/companies/jpmorganchase/jobs/46dbcaf3f93dc811d42e/) JPMorganChase · Columbus, OH, United States ### [Principal Software Engineer - Security Platforms](https://jobs.opennash.com/companies/jpmorganchase/jobs/840d796d17ca7a9bcced/) JPMorganChase · Columbus, OH, United States ### [Manager Director - Aerospace & Defense](https://jobs.opennash.com/companies/huntington-bank/jobs/83276c564e6d939f8863/) Huntington Bank · Farmers, TX Charlotte, NC VA MI IL NY ### [Lead Security Engineer - Threat Management Platforms & Integrations](https://jobs.opennash.com/companies/target/jobs/d56507f880c3142d058b/) Target · Mongolia OpenNash lists jobs from employers’ own careers sites and does not handle applications.
