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

Our team is growing, and we’re looking for a Senior Product Security Engineer to dig deep into our endpoint products, find design and implementation flaws, and help our product engineers fix problems and ship secure code. If you like to rip apart Linux applications to see how they work and find security flaws; if you want to actually play a part in fixing flaws rather than just reporting them and hoping for the best – we want to hear from you!

What You’ll Do

• Join project teams working on product improvements and new products as a security expert and advisor, influencing the design and capabilities of our world‑class endpoint protection products, with a focus on the endpoint sensors
• Create and update threat models to help drive security decisions
• Read and review source code for applications, looking for security flaws and vulnerabilities; you’ll have tools to help you but you’ll be digging deeper than tools can
• Think like a hacker and attack endpoint applications with kernel components, mostly before they go to production; again, you’ll have tools to help you, but you’ll do more than tools can
• Work with developers to help them understand problems, risks, design weaknesses, etc. and figure out good solutions
• Build tools and automation to make your life/your team’s life/developers’ lives easier
• Validate and replicate some kinds of bug bounty reports, and hunt for similar issues in affected applications

What You’ll Need

• 10+ years of experience in engineering, ideally in security. Experience programming in or assessing security of C/C++ apps for Linux
• Proficiency of system internals and security features for Linux
• Comfort with concurrency considerations in multi-threaded applications
• Understand the security implications of containerization and virtualization
• A working understanding of how software products are created and shipped in Agile/DevOps like environments – enough to have a positive working relationship with product engineers (software product development experience is a huge plus, but not a requirement)
• A solid understanding of common software weaknesses that impact endpoint and client/server applications; you’ll be hunting for these, you need to know them when you see them and be able to help product engineers understand and fix them
• Comfort with collaborating across technical teams: asking technical questions, challenging assumptions, getting or providing context for decisions, etc.
• Proven experience utilizing AI technologies to enhance decision‑making, streamline workflows and processes, improve efficiency and drive business outcomes.

Bonus Points

• Rust & Go programming
• Experience with debuggers like Ghidra, IDA Pro, or other similar tools
• Experience developing/maintaining automation for application security tasks
• Experience developing and using threat models, especially using STRIDE
• Application penetration testing experience, especially if it includes testing against install packages and control bypass methods
• Reverse‑engineering or malware analysis, or related security research capabilities

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

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.
