## Description

Help us protect CrowdStrike and its customers from the most advanced threats by securing our applications. CrowdStrike's Product Security team breaks the mold of traditional internal security, and focuses on active threats to CrowdStrike's products. As a Senior Application Security Engineer you will dig deep into web applications, find design and implementation flaws, help our product engineers fix defects, and play a role in shipping secure code. You'll be actively involved in fixing defects rather than just reporting them and hoping for the best. Additionally, you will be integral to cross-cutting projects to further harden internal systems and processes against active and emerging threats.

What You'll Do:

 * Join engineering teams working on applications as a security expert and advisor, influencing the design and capabilities of our products
 * Create, maintain, and mature threat models to drive security architecture review and eliminate threat surface area
 * Review application source code, looking for security defects and risk
 * Attack applications throughout the Secure Development LifeCycle
 * Work with developers to help them understand defects, risks, design weaknesses, etc. and implement proven solutions
 * Build integrated tools and automation to make life easier for you, your team, and our engineering partners
 * Drive response efforts to our bug bounty program, hunt for similar issues across the platform, and improve the security of our applications
