Summary Generated by Built In

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 also a mission-driven company. We cultivate a culture that gives every CrowdStriker both the flexibility and autonomy to own their careers. 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:

The Counter Adversary Operations (CAO) Team is a team that brings together CrowdStrike Falcon® Intelligence and the CrowdStrike® Falcon OverWatch™ threat hunting team to disrupt today’s adversaries and ultimately raise their cost of doing business. Both threat hunting and intelligence operations are essential to detect, disrupt and stop today’s adversaries. CrowdStrike Counter Adversary Operations will have the power of both — along with the trillions of telemetry events from the AI-powered CrowdStrike Falcon® platform — to quickly act and intensify its impact on adversary activity. CrowdStrike’s deep adversary knowledge, expertise in pursuing and stopping threats, and visibility derived from the Falcon platform make us uniquely qualified to deliver the most effective method of stopping breaches and protecting customers.

You can also take a closer look at some of the CAO projects here.

CrowdStrike is looking for a Front-end Software Engineer to build globally distributed, robust and customer-centric solutions.  You and your team will provide a high-quality user experience that our customers around the world use 24/7 to protect their systems from the most sophisticated adversaries.
We build Falcon Console on top of a cutting edge frontend framework leveraging Web Components, but if you have used React or other modern UI frameworks, you will feel right at home. Since we only support evergreen browsers, we can push the boundaries of what’s possible on the web platform while working with truly massive amounts of data. Our ideal candidates are sensitive to the needs of the users and love to find solutions in a unique and dynamic problem space.

We’re a highly collaborative, friendly, inclusive and diverse group that prizes collaboration over competition. We provide opportunities to learn new skills, mentor fellow engineers, and contribute to the direction of both the team and the products for which we’re responsible. We work in a distributed, remote-first, high-trust environment where you manage your own time and have the flexibility to balance your work and personal life.
 
Our ideal candidate will be responsible for taking full ownership of the delivery of our products, driving the technical aspects, helping the team to define the architecture and coordinating with stakeholders in terms of scope and priorities.

What You’ll Do:

  • Hands on engineering–creating world-class user experiences built on our micro-frontend architecture using Web Components and the Lit framework.

  • Build and maintain single page web applications written in JavaScript using Ember.js and Kestrel.

  • Write automated tests for your code.

  • Collaborate with fellow UX Engineers, Cloud Engineers, UX Designers, User Researchers, QA Analysts, Product Managers, and others.

  • Continually learn about the ever-evolving challenges and complexities of the cybersecurity industry.

  • Have fun solving hard problems      

What You’ll Need:

  • 7+ years of end-to-end UI/UX ownership, with a proven track record of leading design strategy and user flows from concept to delivery.

  • A good understanding of JavaScript, particularly TypeScript, and experience building web application user interfaces with modern frameworks such as React, Vue or Angular.

  • Strong web development fundamentals, starting with HTML & CSS skills.

  • Experience with testing frameworks, tools and methodologies such as Jest, Playwright, or Cypress.

  • Knowledge & interest in developing genuinely accessible interfaces.

  • Comfortable with Git or similar version control systems and workflows.

  • A desire to work closely with others to deliver quality software and solve problems.

Bonus Points:

  • Familiarity with client-side build processes and tools (e.g. Webpack, Vite etc.).

  • Experience creating or contributing to open-source projects.

  • Experience with graphics and visualization tools such as D3 or Three.js.

  • Experience with UI performance measurement and optimization.

  • Experience with web accessibility testing and support.

  • Familiarity with Amazon Web Services.

  • Prior experience in cybersecurity.

  • Prior experience building enterprise software as a service.
