Sr. Engineer, Frontend - Data Platform Experiences (Hybrid, London)

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.

We're looking for a Senior UI Engineer to join Data Platform Experiences, a new team inside CrowdStrike's Data Platform group. Our charter is to own the customer-facing surface of the Data Platform: making it easy to publish new data and to find, understand, and query existing data. That work spans three pillars: a centralized UI/UX capability specialized in data-first interactions (schema exploration, lineage, query surfaces, semantic layers); the Data Platform Concierge — an agentic front door that turns a business question into the right dataset with the right context; and self-service onboarding and enablement so new consumers and domain teams can operate without a tour guide. If you get excited about building a UI that turns dense, technical data surfaces into experiences people can actually use — dashboards, query builders, exploration tools, semantic layer UIs, and the agentic surfaces that increasingly sit on top of them — we want you on our team. Our frontend stack is a mix. External customer-facing work is transitioning from an Ember-based platform to a new UX that keeps Ember at its core (routing, services, dependency injection) while opening the door to Web Components, Lit, and other frameworks at the page and component level. React has a meaningful footprint today, especially in our AI-adjacent surfaces, where it typically lives inside a Web Component host. TypeScript runs through most of it. Internal tooling has room for other modern frameworks where they fit. You'll work across all of it, and you'll help shape the shared component language the rest of the Data Platform builds on. What You’ll Do: Design and build data-first UI surfaces — schema exploration, lineage, query, semantic modeling, dashboards, and the interfaces around the Data Platform Concierge. Contribute to and extend a shared component language used across Data Platform surfaces so consumers get a consistent experience wherever they land. Partner closely with UX, backend, and platform engineers to turn platform primitives into experiences a consumer can walk through on their own. Raise the bar on frontend engineering practices — testing, build and deploy pipelines, component architecture, and accessibility — in a large, complex application landscape. Mentor other engineers on the team and act as a design-review partner for customer-facing surfaces across the Data Platform group. What You’ll Need: TypeScript & Modern JavaScript — Strong proficiency with TypeScript, ES6+, and modern JavaScript patterns for large-scale applications. Frontend framework depth — Strong working knowledge of at least one major JavaScript framework (React, Vue,
