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 developer tooling foundation for our next-generation front end. It's a strategic role for someone who wants to shape how hundreds of UI engineers scaffold, build, integrate and ship 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 developer tooling, build infrastructure, dependency management and CI into a single internal platform that teams pick up themselves. This role is central to that mission and you'll build the module federation foundations, build pipelines, scaffolding and automation that every UI team relies on to stay productive at scale.\n What You'll Do:\nOwn the module federation architecture that lets dozens of Product Groups ship independent microfrontends into a single UI shell, keeping contracts stable, versions honest and cross-team breakage rare.\nLead the shared Vite build and dev-server tooling that every UI engineer runs locally and in CI, keeping hot reload fast, sub-package watch reliable and cold starts honest.\nDesign and run the CI pipelines that build, verify and publish every UI package across GitLab CI and Jenkins, keeping them fast, cacheable and giving engineers a clear signal when something breaks.\nShip the single CLI that is the front door to the platform to scaffold a repo, wire it into module federation, run its tests, cut a release with one command for everything a UI engineer does locally and in CI.\nWire automated dependency management (Renovate), security scanning and AI-assisted upgrades into the paved road so version bumps, vulnerability response and monorepo hygiene don't fall on individual teams.\nShift left: move linting, type checks, build validation and contract checks into the developer's editor and pre-push hooks so engineers catch issues in seconds, not in a failed pipeline twenty minutes later.\nWork with UI Quality, UI Release and Observability so the platform feels like one thing through a single CLI.\nPair with Product Group leads to migrate legacy build and tooling patterns onto the paved road and get the tooling strategy adopted across the organisation.\nMentor engineers on build tooling, module federation and monorepo patterns, and give thoughtful code review across the platform and its consumers.\nBuild the ephemeral environments and preview deployments per MR so engineers get fast, honest feedback on their changes before they merge.\n What You'll Need:\nYou've built shared frameworks, tooling or platforms that other engineers rely on day to day.\nYou know Vite and modern front-end build tooling well, and you're comfortable diagnosing issues deep in the module graph.\nYou've shipped module federation (or equivalent microfrontend architecture) in production at scale, and you understand the versioning, contract and runtime pitfalls.\nYou're fluent in TypeScript, monorepo tooling (Nx, Turborepo or similar) and modern package management (pnpm workspaces).\nYou've designed GitLab CI pipelines that stay fast and reliable and give engineers a clear signal when something breaks.\nYou've automated dependency management (Renovate or similar) and pulled security tooling (SAST, SCA, Snyk) into developer workflows.\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.\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.\nProven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.\nBonus Points:\nPlaywright and modern browser test tooling wired into CI as a fast, reliable signal.\nRunning Jenkins alongside modern CI during a platform migration.\nEphemeral preview environments per MR and the infrastructure automation behind them.\nDeveloper experience metrics like DORA or SPACE, and using them to drive tooling investment.\nContract testing between federated remotes in a large distributed front end.\n#LI- GO1\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.
