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.\nAbout the Role:\nWe're looking for a Senior UI Platform Engineer to lead the design and build of the shared quality foundation for our next-generation front end. It's a strategic role for someone who wants to shape how hundreds of UI engineers ship, test and operate their code across the organisation.\nUI Platform owns the paved road for UI engineering at CrowdStrike. As Product Groups migrate onto the new UI, we're consolidating quality, release, observability and developer tooling into a single internal platform that teams pick up themselves. This role is central to that mission where you'll build the testing framework, pipelines and quality signals that every UI team relies on.\nWhat You'll Do:\nLead the shared UI testing framework that every Product Group uses, from unit and component tests through to end-to-end and visual regression.\nDesign and run the CI pipelines that gate every UI release across GitLab CI and Jenkins, keeping them fast, reliable and honest about failures.\nShip the UI Quality Score as a public signal that brings together coverage, escaped defects, skipped tests, incident data and dependency health.\nWire automated dependency management, security testing and AI-assisted test authorship into the paved road so upgrades, vulnerability response and quality work don't fall on individual teams.\nWork with UI Developer Tooling, UI Release and Observability so the platform feels like one thing through a single CLI.\nPair with Product Group leads to move legacy testing patterns onto the paved road and get the testing strategy adopted across the organisation.\nMentor engineers on testing practice and quality patterns and give thoughtful code review across the platform and its consumers.\nBuild the quarantine and triage system for flaky tests so intermittent failures stop blocking releases and get fixed rather than ignored.\nWhat You'll Need:\nYou've built shared frameworks, tooling or platforms that other engineers rely on day to day\nYou know Playwright well for browser end-to-end testing and you're comfortable with unit and component testing (Vitest or similar) and visual regression.\nYou're fluent in TypeScript, Vite and modern front-end tooling.\nYou've designed GitLab CI pipelines that stay fast and reliable and give engineers a clear signal when something breaks.\nYou've set engineering standards that autonomous teams have genuinely adopted and you can influence senior engineers and leaders when it matters.\nYou've used AI in earnest to change how engineering work gets done, not as a novelty.\nProven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.\nYou don't need to tick every box. If most of the “What you'll need” list sounds like you, we'd like to hear from you.\nBonus Points:\nAutomated dependency management (e.g. Renovate) and pulling security testing (SAST, SCA) into developer workflows.\nContract testing and mocking frameworks for large distributed systems.\nWorking with developer experience metrics like DORA or SPACE.\nRunning Jenkins alongside modern CI during a platform migration.\nBenefits of Working at CrowdStrike:\nMarket leader in compensation and equity awards\nComprehensive physical and mental wellness programs \nCompetitive vacation and holidays for recharge \nPaid parental and adoption leaves\nProfessional development opportunities for all employees regardless of level or role\nEmployee Networks, geographic neighborhood groups, and volunteer opportunities to build connections\nVibrant office culture with world class amenities\nGreat Place to Work Certified™ across the globe\nCrowdStrike is proud to be an equal opportunity employer.
