Security Engineer, AmSec

Amazon Security is seeking a Security Engineer who thrives in ambiguity and is motivated to build scalable security solutions. The Secure Third Party Tools (S3T) team has bold ambitions to redefine how Amazon protects customer trust across all third-party interactions - shifting from reactive assessments to proactive, automated protection at global scale. Security Engineers are integral to this mission, combining deep technical review expertise with a builder's mindset to influence the AI-powered tooling that scales our impact.

They must demonstrate excellent written and verbal communication skills, strong ownership on review engagements, integrating GenAI to improve operationally efficiency, and solid understanding of vendor security risk and effective controls.

Key job responsibilities

• Perform technical deep-dive security reviews of third-party services across diverse and ambiguous use cases, including AI/ML integrations, cloud architectures, and services handling sensitive customer data
• Identify and trace data flows through complex systems, evaluating where security controls are lacking or require supplementation
• Evaluate vendor penetration test reports, assessing finding applicability and severity within the context of each engagement
• Threat model third-party use cases to rapidly surface sharp edges and drive risk-proportionate decisions
• Influence and contribute to AI-powered security tooling that automates and scales review decisions across the organization
• Clearly communicate identified risks and recommendations to service teams and leadership, driving resolution through escalation when needed
• Author and improve security baselines, decision rubrics, and implementation patterns for novel third-party use cases

A day in the life

Security Engineers work backwards from customer risk to identify what matters most in a third-party engagement - there is no checklist. You'll apply threat modeling, architecture analysis, and enterprise security control knowledge to bottom out on key risks quickly, then translate findings into clear, actionable guidance. When barriers arise, you focus on solutions: scripting, leveraging AI tools, and codifying decisions in S3T tooling so the next review is faster and more accur.
