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, We're building a welcoming & flexible team that prizes collaboration over competition, one which provides opportunities to learn new skills, mentor junior and senior developers and contribute to the direction of both the team & the products for which we're responsible. This is a high trust environment where we allow team members to manage their own time, take holidays as they need it and reward them with competitive salaries and equity. The Falcon endpoint agent is able to react in near-real-time to changes in the threat landscape, and underpinning this is the ability of the endpoint agent to quickly query our cloud for new information. This system operates within tight latency and response time constraints at a scale matched by few other environments, and the scale is only growing. CrowdStrike is seeking a Software Developer in Test for our Cloud Detections Platform team, which is tasked with building CrowdStrike's next generation detection platform. In this capacity, you will be in charge of developing and operating the team's CI/CD pipeline, making sure our solutions work, and raising the alarm when they suddenly don't. You'll be building out an end-to-end validation pipeline, largely from scratch, leveraging existing frameworks and tooling where possible, but able to color outside the lines when necessary., * Verify component, system integration and application level features and functionality to ensure our reliability, accuracy and performance reaches our standards for quality. * Participate in code and design reviews and provide technical guidance and feedback to team members. * Review engineering technical design documents and requirements. Provide guidance and strategy about how and where to build in testability. * Engage in continuous improvement of our end-to-end test and validation processes. * Increase and improve our automated test coverage, and contribute to existing tools, frameworks and related solutions. * Leverage new open source solutions to build new tools that test things in new ways. * Improve our delivered product quality across our entire platform and applications. * Collaborate on determining root causes of production outages and adding quality improvements to prevent outages in the future. * Crowdstrike is a remote-friendly company, but we do get together from time to time. Some travel will be required for in-person meetings. * Build and manage CI/CD pipelines using Jenkins, Github actions or similar tools.
