Employment Type: Full time

About The Role

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 an Application Security Engineer you will dig into web applications, find design and implementation flaws, help our product engineers fix defects, and play a role in shipping secure code. You’ll hunt for security defects and play a part in fixing those defects rather than just reporting them and hoping for the best. Additionally, you will be involved in 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 and maintain threat models to drive security decisions and minimize 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
• Assist in responding to our bug bounty program, hunt for similar issues, and improve the security of our applications

We’re hiring this role at multiple levels, so we still want to hear from you even if you think you can’t do all of that – or if you can do more!

What You’ll Need

• A moderate understanding of how software products are created and shipped in Agile/DevOps like environments
• Moderate experience with threat modeling, especially using STRIDE
• Code review experience for apps built with Go (Golang), Python, or Java
• Knowledge of secure configuration of cloud-native and containerized apps in one or more Cloud environments (GCP, Azure, AWS)
• Experience using and/or maintaining commercially available AppSec tools like SAST, DAST, CSPM, DSPM, and ASPM suites
• An understanding of common software weaknesses that impact cloud and web applications (not just the OWASP Top 10) and experience in application penetration testing
• Comfort with collaborating across technical teams: asking technical questions, challenging assumptions, getting or providing context for decisions, etc.
• Experience with driving ambiguous research projects

Bonus Points

These skills are not required and/or we’re willing to teach them, but they are helpful.

• Self-motivated to identify security problems and engage with teams to find solutions
• Demonstrable experience developing/maintaining automation for application security tasks and defect identification
• Example(s) of having a positive working relationship with product engineers (software product development experience is a huge bonus)
• Knowledge of Docker and Kubernetes (k8s)
• Can explain and demonstrate the limitations of AI
