As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission hasn’t changed — we’re here to stop breaches, and we’ve redefined modern security with the world’s most advanced AI-native platform. We work on large scale distributed systems, processing almost 3 trillion events per day and this traffic is growing daily. Our customers span all industries, and they count on CrowdStrike to keep their businesses running, their communities safe and their lives moving forward. We're proud to work for a mission-driven company leveraging AI to transform the way we work. CrowdStrikers drive their careers through flexibility and autonomy while also being expected to contribute to a culture of responsible AI adoption, experimentation, and innovation. We use an AI-first mindset as a force multiplier to proactively and continuously accelerate execution, build expertise, uncover insights, and solve complex problems. We’re always looking to add talented CrowdStrikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other. Ready to join a mission that matters? The future of cybersecurity starts with you.

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

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
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

Bonus Points

• 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 assisted development and associated security implications
• Engaged in providing security enhancements to open source projects
• Experience with threat intelligence driven testing and adversarial emulation

Education/Certifications

Technical security certifications or academic background are a plus.

Benefits of Working at CrowdStrike

• Market leader in compensation and equity awards
• Comprehensive physical and mental wellness programs
• Competitive vacation and holidays for recharge
• Paid parental and adoption leaves
• Professional development opportunities for all employees regardless of level or role
• Employee Networks, geographic neighborhood groups, and volunteer opportunities to build connections

CrowdStrike was founded in 2011 to fix a fundamental problem: The sophisticated attacks that were forcing the world’s leading businesses into the headlines could not be solved with existing malware-based defenses. Founder George Kurtz realized that a brand new approach was needed — one that combines the most advanced endpoint protection with expert intelligence to pinpoint the adversaries perpetrating the attacks, not just the malware. There’s much more to the story of how Falcon has redefined endpoint protection but there’s only one thing to remember about CrowdStrike: We stop breaches.
