• Design and implement practical security controls across cloud platforms, applications, products, and data, and guide engineering teams in doing the same;
• Develop and apply threat models to identify architectural risks, trust boundary issues, and failure modes before they become incidents;
• Partner with engineering, product, and operational teams as a trusted security adviser by providing patterns, guidance, and guardrails;
• Contribute to the detection, investigation, and containment of security incidents, and drive systemic improvements based on lessons learned;
• Build automation, improve tooling, and embed secure-by-default practices to reduce manual and reactive security work;
• Contribute technical expertise to audits, certifications, and customer security reviews, ensuring controls are effective and not only documented.

• Influence outcomes without relying on formal authority;
• Apply a risk-based mindset and make proportionate, well-reasoned decisions under uncertainty;
• Experience working across multiple teams and technical domains simultaneously;
• Track record of identifying gaps and driving security improvements to resolution in ambiguous or loosely scoped problem spaces;
