Offensive Security Engineer

About the team

The Attacker Engineering team performs offensive security assessments and penetration testing to identify vulnerabilities and weaknesses in Stripe's systems, applications, and networks before they impact Stripe’s business or users. We partner with other Stripe teams to defend against external attacks and respond to security incidents. The team is distributed, working primarily in Eastern and Pacific time zones, and will regularly coordinate with stakeholders in Europe and Asia.

What you’ll do

Using your security expertise, you'll uncover security weaknesses within Stripe by simulating the tactics, techniques, and procedures (TTPs) of real-world adversaries. This will involve utilizing both threat intelligence and collected telemetry to emulate cyber and criminal threat actors who may target Stripe. Lastly, your analytic capabilities will be critical during security incidents to reduce uncertainty, uncover root causes, and inform future prevention and detection mechanisms.
