• Optimize component performance and bundle size for production environments
• Maintain and extend design tokens (CSS variables) to ensure coded components remain in sync with Figma design specifications
• Conduct thorough code reviews and provide constructive technical feedback to team members
• Drive technical decision-making for component architecture and implementation patterns
• Serve as a subject matter expert for engineering teams integrating with the design system
• Collaborate with UX architects, product designers, and QA engineers to ensure components meet our design and engineering standards
• Monitor integration support channels and provide timely technical assistance
• Create and maintain comprehensive component documentation, including usage guidelines, API specifications, and integration examples
• Proactively gather feedback from consuming teams and iterate on components to improve developer experience
• Document patterns and best practices to enhance the overall developer experience
• Provide short demos showcasing your work and new component capabilities
• Implement and maintain CI/CD pipelines for automated testing and quality assurance
• Participate in scrum ceremonies, team planning sessions, and roadmap reviews to ensure team alignment on short and long-term goals
• Support multiple initiatives by providing essential UI components and UX patterns
• Mentor junior engineers and provide technical guidance on design system best practices

Requirements

• 5+ years of professional frontend engineering experience

• Hands-on experience building user-centric and scalable UI frameworks and design systems
• Experience with REST APIs and GraphQL
• Strong understanding of responsive design principles and implementation
• Experience with Playwright or similar modern testing frameworks
• Hands-on experience with design tokens and CSS-in-JS solutions
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.
• Deep experience with Accessibility (a11y) best practices, tools, and techniques including: Keyboard navigation compatibility, Screen reader support, WCAG 2.2 AA compliance
• Proven experience with localization and internationalization (i18n) implementation
• Track record of achieving and maintaining high test coverage standards
• Knowledge of CI/CD best practices and tools for improving and maintaining performance and code quality
• Experience with monorepo architectures and tooling (Nx, Turborepo, or similar)
• Experience with Storybook or similar component documentation tools

Qualifications

• Experience with frontend frameworks such as React/Next.js, Vue, or Ember
• Experience with AgGrid or similar data grid libraries
• Experience building UIs for data-intensive security or cybersecurity products
• Understanding of security best practices in frontend development
• Experience working with globally distributed teams
• Contributions to open-source design systems or component libraries
• Experience with design system migration projects
• Comfortable leveraging AI tools (Claude, Copilot, etc.) to accelerate development and improve productivity

Preferred Qualifications

• Experience with AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.
• Experience with design system governance, including establishing and enforcing component standards and patterns
• Experience with design system migration projects
• Experience with AI tools (Claude, Copilot, etc.) to accelerate development and improve productivity

How You'll Demonstrate CrowdStrike Leadership Principles

• Customer Focus: Build components with internal engineering teams and end users in mind. Treat developers as valued customers deserving of an excellent experience. Ensure consistent experiences through accessibility and thoughtful design.
• Partnering: Collaborate with designers, engineers, and stakeholders across the organization. Build strong working relationships with cross-functional teams. Support and unblock teams integrating with the design system. Ensure accountability. Own component quality through comprehensive testing and documentation. Follow through on commitments and hold yourself to high standards. Establish clear quality metrics and consistently deliver against them. Cultivate innovation. Drive improvements in design system architecture and developer experience. Introduce new approaches to component development and testing. Stay current with industry trends and bring fresh ideas to the team. Communicate effectively. Provide clear technical guidance through documentation and demos. Adapt communication style for different audiences (technical and non-technical). Actively listen and incorporate feedback from stakeholders.
• Demonstrate self-awareness: Proactively seek feedback on your work and approach. Reflect on team processes and suggest improvements. Openly discuss challenges and learn from experiences.
