Job description

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 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

• 7+ years of experience in CyberSecurity, with expertise in identifying security defects and engage with engineering teams to find solutions
• A deep understanding of how software products are created and shipped in Agile/DevOps like environments
• Experience with threat model framework(s), especially using STRIDE
• Proven experience in manual secure code review for apps built with Go (Golang), Python, or JavaScript
• Understanding of browser security implementations across platforms (Chrome, Firefox, etc. for desktop and mobile) with strong experience across the following: TypeScript, React, Node.js, Electron
• Demonstrable proficiency in hands-on review and testing of API endpoint security
• A working knowledge of secure configuration of cloud-native and containerized apps in multiple Cloud environments (GCP, Azure, AWS)
• Experience using and/or maintaining commercially available AppSec tools like SAST, DAST, CSPM, DSPM, and ASPM suites
• A solid understanding of common software weaknesses that impact cloud and web applications (not just the OWASP Top 10) and demonstrable experience in application penetration testing
• Examples of collaborating across technical teams: asking technical questions, challenging assumptions, getting or providing context for decisions, etc.
• Demonstrable experience developing/maintaining automation for application security tasks and defect identification.
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

• Experience working at extremely large scale
• Comfortable with ambiguity and capable of determining direction
• Example(s) of having a positive working relationship with product engineers (software product development experience is a huge bonus)
• Deep knowledge of Docker and Kubernetes (k8s)
• Experience with WebAssembly (WASM), Kotlin, or Scala
• Engaged in providing security enhancements to open source projects
• Experience in mentoring, coaching, and/or improving team culture

• 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
• Vibrant office culture with world class amenities
• Great Place to Work Certified™ across the globe

About the role

This is a Senior Level role in the Technology field (Cybersecurity) at CrowdStrike. Senior roles usually expect substantial experience, ownership of results and often the ability to guide others.

We could not match this job title to one occupation in the official wage statistics, so no pay estimate is shown. Pay is not in the source listing; ask the employer for the range and compare in the 240 job niches.

How to prepare and behave

This is editorial guidance, not information from the employer.

• Read the whole description and match your examples to its requirements; use the same words the posting uses where they are true for you.
• Research the employer before the interview: what it does, who its customers are and recent news; prepare two or three questions about the work.
• Arrive early (or log in early for a video call), dress one step above the daily dress code, and test your camera and audio beforehand.
• Answer with short stories: the situation, what you did and the result. Give numbers when you have them and never invent them.
• Be honest about gaps; say what you did to learn and how fast you can close them.
• Ask about the team, the first 90 days, how success is measured and the schedule; do not open with salary and time off.
• When pay comes up, know the market range for the occupation and your lowest acceptable offer before you answer; ask for the full package in writing.
• Send a short thank-you message within a day, mentioning one thing you discussed.
• The listing mentions a remote or flexible location. Confirm with the employer whether remote work applies to your state: taxes, licensing and benefits can depend on where you live.
• Have code, data work or projects you can show, and be ready to think aloud: many technical interviews test how you reason, not only the answer.

Know your rights as a candidate and an employee:

• U.S. Equal Employment Opportunity Commission: prohibited employment practices
• U.S. Department of Labor: Wage and Hour Division
