Design Engineer

Who you are

• Experience in a hybrid design and engineering role with the ability to bridge both disciplines
• Proficiency in web technologies including HTML, CSS, JavaScript/TypeScript, and at least one modern framework such as React, Vue, or Next.js
• Experience building or operating AI application tooling, such as MCP server integrations, custom agent development, evaluation harnesses, or comparable infrastructure for LLM-based products
• Systems thinking across tool chains, with the ability to design how separate tools compose into a single coherent workflow
• Experience with hosting, deployment, and CI/CD pipelines (e.g., GitLab Pages, AWS)
• Familiarity with API integration and working with real data in prototypes or tools, including secure credential handling
• Experience building or maintaining shared tooling, component libraries, or developer and designer toolchains
• Working knowledge of security and compliance requirements relevant to web applications, including PII handling and secure data access
• Familiarity with AI-assisted development tools such as Cursor, Figma Make, Claude, v0, or similar
• Strong communication skills with the ability to collaborate effectively with both designers and engineers from different backgrounds
• Design experience or strong design sensibility, including the ability to participate meaningfully in a design critique, read a Figma file fluently, and recognize when a prototype needs more than a technical fix
• A degree in Computer Science, Design Engineering, Human-Computer Interaction, or a related field, or equivalent practical experience

What the job involves

• Serve as the technical owner of the platform AI-assisted design workflows are built on, acting as the primary point of contact for workflow leads and engineering
• Build and maintain integrations that connect AI tooling to the systems designers already work in
• Maintain practices that keep AI-assisted work reliable, including versioning, evaluation, and quality regression checks
• Partner with leads across UX to establish an integrated, AI-assisted design process that raises both quality and efficiency
• Map and maintain how work moves between stages, ensuring the right context travels with it and each stage produces what the next one needs
• Make outputs structured and legible so the team can measure and improve the parts of the process that matter most
• Establish and maintain secure, compliant patterns for designer-built tools and prototypes that touch real product data, in partnership with security and privacy teams
• Build infrastructure that lets designers prototype against real data and live content safely
• Serve as the technical support resource for designers building AI-assisted prototypes, unblocking authentication issues, broken integrations, and environment problems
• Own hosting and deployment infrastructure for designer-built prototypes, micro-apps, and tools
• Help designers develop and maintain a shared library of AI tools and workflows, including reusable assistants, automations, and commands
• Support designers as they build out a shared UI component library for prototyping
• Act as the primary liaison between UX and engineering on infrastructure matters, aligning on shared standards and ensuring consistency with Roku's broader technical systems
