About the RoleWe're looking for a creative and technical Platform Design Engineer to join our Platform Engineering team. This role is central to advancing our Platform + Design initiatives, tackling key customer pain points, and delivering high-quality, scalable experiences across all of Cloudflare. You will be a critical bridge between design and engineering, turning ambitious concepts into production-ready code and making high-impact improvements to areas that span our entire product suite.
You'll partner closely with the Design organization to scope, build, and ship everything from large-scale strategic overhauls to foundational design patterns and fixes to customer experiences. This role is perfect for a frontend-focused engineer who has a passion for design, a strong eye for detail, and a desire to build systems that empower other developers.
Key Responsibilities

• Implement Strategic UX Overhauls: Partner with Design to execute high-impact projects, such as overhauling company-wide interaction patterns, standardizing templates, or re-imagining dynamic customer journeys.
• Build Foundational Design Patterns: Engineer, update, and maintain reusable components and patterns that accelerate feature delivery for all product teams.
• Contribute to the Design System: Ensure new and updated patterns are scalable, performant, and contributed back to our internal design systems for global use.
• Explore "North Star" Concepts: Pair directly with designers to explore future-state "North Star" proposals, building prototypes in both Figma and code to validate ideas and inform future roadmaps.
• Targeted UX enhancements: Triage, prioritize (with design), and rapidly fix small enhancements, polish items, and bugs reported by customers and internal teams.
• Add Polish and Enhancements: Elevate the user experience by adding thoughtful microinteractions and polish to components and core workflows.

Qualifications

• 4+ years of experience in a hybrid Design Engineer, UI Engineer, or Frontend Engineer role with a strong design focus.

• A strong portfolio showcasing your ability to translate complex design concepts (Figma, Sketch, etc.) into high-quality, pixel-perfect code.
• Hands-on experience building, maintaining, or contributing to a component library or design system (e.g., using Storybook).
• Excellent communication and collaboration skills, with a proven ability to work effectively with designers and product managers to scope work and find scalable solutions.
• A pragmatic and product-oriented mindset, capable of balancing technical debt, design intent, and development velocity.

Preferred Skills

• Experience with UX prototyping and iterating in both high-fidelity (Figma) and code-based tools.
• A keen eye for motion design and experience implementing subtle microinteractions and animations.
• Familiarity with web accessibility (WCAG) and building inclusive interfaces.
• Experience working on large-scale, platform-level products used by multiple teams.
• Ability to triage and prioritize a backlog of small enhancements and bugs based on impact and effort.
