Amazon's Corporate Security Response (AWS CorpSec) team is the front line defending one of the world's largest and most complex corporate environments. We detect, investigate, and respond to security threats across Amazon — from targeted campaigns to advanced persistent threats — operating as part of a global, follow-the-sun security response capability.

We are seeking a Security Engineering Manager to serve as a Site Lead for our APAC location. This is a hands-on technical leadership role where you will lead a team of security engineers while personally driving complex investigations, shaping autonomous security tooling, and raising the bar for operational excellence across the team. This is not a coordination role. You will investigate. You will build. You will lead from the front.

Key job responsibilities
**Lead Security Incident Response Operations**

• Own and drive complex security investigations end-to-end — from triage through containment, remediation, and closure
• Lead cross-functional incident coordination with Legal, Security, and engineering leadership, delivering clear risk assessments and recommended actions
• Maintain situational awareness of the global threat landscape and translate intelligence into actionable defensive measures

**Shape Autonomous Security Investigation**

• Define investigation user stories that codify expert security tradecraft into autonomous agent behavior
• Own the quality feedback loop: review agentic output, validate scoring, and drive precision/recall toward production targets
• Review guardrails and policies governing autonomous agent actions, balancing automation velocity with safety

**Build and Lead a High-Performing Team**

• Recruit, develop, and retain security engineers who thrive in ambiguity, form independent risk assessments, and drive outcomes through direct action
• Provide technical mentorship across incident response, threat analysis, forensics, and security automation

**Drive Automation and Process Improvement**

• Identify recurring patterns and systemic gaps, then deliver detection rules and automation to close them
• Lead the transition from manual investigation to scalable agentic capabilities, measuring throughput improvements

About the team
CorpSec Response operates 24/7 as a global, follow-the-sun team protecting Amazon's corporate infrastructure. We combine deep human expertise with leading autonomous investigation capabilities. Our engineers are hands-on investigators who also shape the AI systems that augment their work — creating a unique feedback loop between human security expertise and machine-scale automation.

Inclusive Team Culture
We are committed to building a diverse and inclusive team. Amazon's culture of inclusion is reinforced within our Leadership Principles, which remind team members to seek diverse perspectives, learn and be curious, and earn trust.

Work-Life Balance
We value sustainable performance. Our follow-the-sun model means you're not carrying a pager 24/7 — your node owns its shift, and clean handoffs are a core operational discipline.

Growth and Impact
This role offers a rare combination: hands-on technical security work at massive scale, leadership of a high-performing team, and direct influence over an AI-augmented security platform. You'll grow as both a security practitioner and a technical leader.

Mentorship and Career growth
We’re continuously raising our performance bar as we strive to become Earth’s Best Employer. That’s why you’ll find endless knowledge-sharing, training, and other career-advancing resources here to help you develop into a better-rounded professional.
