• Develop Python-based tooling and automation to improve investigations, enrichment, response, and operational scale.
• Partner with Product Security to translate threat models, security reviews, and product risks into production detections and response playbooks.
• Investigate security events end to end, including triage, scoping, containment support, and follow-through on remediation.
• Support vulnerability management and operational security practices in ways that align with PCI and SOC 2 expectations.
• Participate in proactive threat hunting, detection improvement, and a 24x7 security incident response on-call rotation.
