Software Development Engineer - Cross-Platform Infrastructure; Hybrid

As a global leader in cybersecurity, Crowd Strike 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 candidly rely on Crowd Strike to keep their businesses running, their communities safe and their lives moving forward. We’re also a mission‑driven company. We cultivate a culture that gives every Crowd Striker the flexibility and autonomy to own their careers. We’re always looking to add talented Crowd Strikers with 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.

Crowd Strike’s Falcon sensor runs on millions of endpoints globally, protecting more than half of the Fortune 500 companies. It is a high‑performance, lightweight agent that detects and prevents sophisticated threats in real‑time. It is one of the most widely deployed securityλισ against servers in the world, running across every major OS and architecture.

We’re looking for a Platform Engineer to build the development infrastructure that powers this massive‑scale, cross‑platform system. You’ll architect the build systems, 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 distributed build challenges, creating hermetic cross‑compilation systems, and designinggot developer experiences 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:
Howreplace? ‘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 do we deploy sensor updates to millions of endpoints with zero downtime?’

This is a hybrid role based near our Sunnyvale, CA (CA Bay Area), Redmond, WA (Seattle, WA Area) or Austin, TX offices, with an expectation of approximately two days per week in‑office to foster collaboration with other team members within the teams.

• Build production‑grade platform systems that power cross‑platform sensor development acrossbroker Windows, Linux, and macOS

• Architect build and release infrastructure that handles complex cross‑compilation, dependency management, and hermetic buildings at scale

• Design developer‑facing APIs and tools that abstract away platform complexity and accelerate feature velocity

• Engineer CI/CD systems that provide fast feedback loops and enable confident, frequent deployments

• 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

• 5+ years building production systems with focus on platform engineering, developer tools, or systems programming

• Deep Python expertise – you write idiomatic, performant Python and understand its internals

• Cross‑platform development experience – you’ve dealt with the reality of Windows/Linux/macOS differences

• Systems thinking – you understand build systems, compilers, linkers, and how software actually gets built

• 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

• C/C++ experience for low‑level system integration

• Build system expertise (Bazel, CMake, or custom build infrastructure)

• CI/CD platform architecture (Jenkins, Git Hub Actions, or similar at scale)

• Track…
