Sr Software Engineer, Cloud – Platform Foundations (Hybrid)

Hybrid - Sunnyvale, California, United States

Jul 1, 2026

$140,000 - $215,000/year

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:

You'll be joining the cloud backend team in the Platform product group responsible for managing the customer lifecycle and their product experience. Whenever a new customer onboards on the Falcon platform, our team manages the automation of orchestrations to give our customers a seamless experience, and for this we build and extend services that are capable of making millions of decisions per second! As part of this team, you will play a critical role in enhancing the existing flow and building the next generation cloud-based access and resource management systems.

Getting customers operational could mean initializing them in our customer stores, setting up requires policies, setting up management groups for their machines, enabling configuration for them in several different dependent services, as well as handling both authN and authZ across internal (e.g. Service-to-service authorization, etc.) and external (e.g. user login, etc) integrations. The group is a critical part of our flagship Falcon Platform product, frequently working collaboratively with many other product groups.

Bring your experience in distributed technologies and algorithms, your great API and systems design sensibilities, and your passion for writing code that performs at extreme scale. You will help build a platform that scales to millions of events per second. If you want a job that makes a difference in the world and operates at high scale, you have come to the right place
