## 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:

Lightning is a suite of services in the CrowdStrike cloud that expose sub-second, near-real-time APIs enabling Falcon Sensors to rapidly obtain threat information. Operating at massive scale, Lightning processes trillions of threat events daily within tight latency constraints - where performance and availability are critical to sensor operation and customer protection., CrowdStrike is seeking a Senior Software Developer in Test (SDET) to enter our team as a bit of a hybrid contributor wearing hats for both the design and creation of custom test tooling, frameworks and systems, as well as for contributing to sub- and main branches of the core product code. In effect, you would ostensibly be the Sr backend developer who is also designated as test SME, validating key features and functionality that spans our processing, data and customer facing application layers to ensure it's able to support low-latency prevention of malware, manage thousands of events per second, query across terabytes of data and deliver accurate information to the endpoint, ensuring it also processes the data properly. To that end, you will guide design discussions and code reviews with a focus on quality, serve as the team's SME for code hygiene, and contribute to service operations - all while continuously expanding test coverage and capabilities. Testing
concerns span functional, performance, contract, and chaos/resilience engineering. Cybersecurity experience is a plus, not a prerequisite.

This is a team which prizes collaboration over competition and places high-trust in contributors. You'll find you have high ownership and high schedule flexibility, as well as high trust placed in your expertise as the team's dedicated SME, in the design and implementation of custom test architecture.

This role is hybrid, requiring 2-3 days per week on-site in one of the posted locations.

What You'll Do:

 * Both build stuff and break stuff!
 * Own end-to-end validation of Lightning services across cloud-side and Falcon Sensor interactions, spanning component, integration, and application levels, while continuously improving test and validation processes
 * Build and own Lightning-specific test tooling and frameworks, while leveraging and contributing to shared organization-wide testing tools and infrastructure
 * Define and drive testing strategies across functional, performance, contract, and chaos testing concerns
 * Guide technical design reviews in quality SME capacity, to provide clear guidance on testability, quality, and code hygiene
 * Leverage new open source solutions to build new tools that test things in new ways.
 * Own code reviews with a focus on quality, serving as the team's SME for code hygiene
 * Contribute to service operations, including improving overall service observability and monitoring, root cause analysis of production issues, and implementing quality improvements to prevent future outages
