Job summary

CrowdStrike Inc. is seeking a Software Engineer to build the development infrastructure powering our Falcon sensor platform across Windows, Linux, and macOS. You’ll design test frameworks, deployment pipelines, and developer tools that scale across 10+ OS/architecture combos.

Hybrid role requiring 2 days on-site per week at Redmond, WA, and collaboration with sensor teams to boost developer productivity and ship production code faster and more reliably.

Qualifications

• 5+ years building production systems with focus on platform engineering, test frameworks, developer tools, or systems programming.
• Extensive Python expertise.
• Cross-platform development experience - you've dealt with the reality of Windows/Linux/macOS differences.
• Test framework experience - you understand test frameworks and the complexity involved to make them robust, reliable, backwards compatible, and work on all platforms.
• Collaboration skills - you can work with distributed teams and translate needs into technical solutions.
• Experience with GenAI-assisted development workflows or building AI-powered developer tools.
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

Responsibilities

• Build production-grade systems that power cross-platform sensor development across Windows, Linux, and macOS.
• Architect test and release infrastructure that handles dependency management and fast, reliable builds at scale.
• Design developer-facing APIs and tools that abstract away platform complexity and accelerate feature velocity.
• Engineer CI systems that provide fast feedback loops and enable confident, frequent merges.
• Drive platform evolution by identifying bottlenecks, prototyping solutions, and shipping improvements that measurably improve developer productivity.
• Collaborate with sensor teams to understand their workflows and build leverage points that multiply their effectiveness.

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

CrowdStrike's Falcon sensor runs on millions of endpoints globally, protecting more than half of the Fortune 500 companies. It's a high-performance, lightweight agent that detects and prevents sophisticated threats in real-time. It's one of the most widely deployed security platforms in the world, running across every major OS and architecture.

We're looking for a Software Engineer to build the development infrastructure that powers this massive-scale, cross-platform system. You'll architect the test frameworks, deployment pipelines, and developer tools that enable our sensor teams to ship production code faster and more reliably. Think of this as building the platform that builds the platform - solving complex challenges, creating frameworks and tools that eliminate friction at scale.

This role sits at the intersection of systems programming, developer productivity, and production infrastructure. You'll work in Python (primarily) with touches of C/C++ when needed, solving problems like: How do we build and test across 10+ OS/architecture combinations in minutes? How do we give developers instant feedback on cross-platform compatibility? How can we make sensor developer's lives better? How do we deploy sensor updates to millions of endpoints with zero downtime?

Location

This role is hybrid, requiring 2x days per week on-site at one of the posted locations.

What You'll Do

• Build production-grade systems that power cross-platform sensor development across Windows, Linux, and macOS
• Architect test and release infrastructure that handles dependency management and fast, reliable builds at scale
• Design developer-facing APIs and tools that abstract away platform complexity and accelerate feature velocity
• Engineer CI systems that provide fast feedback loops and enable confident, frequent merges

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

Bonus Points

• C/C++ experience for low-level system integration
• CI platform architecture (Jenkins, GitHub Actions, or similar at scale)
• Track record of measurably improving developer productivity (e.g., "reduced build times by 60%", "eliminated 80% of cross-platform bugs pre-merge")
