Qualifications

• 5+ years of design engineering, front-end engineering, or a related hybrid role.
• Degree in Computer Science, Human-Computer Interaction, Design, or equivalent practical experience.
• Portfolio of relevant work and code samples demonstrating strong interaction design sensibility, technical execution, and polished final outcomes.
• Strong experience using generative AI tools to assist with coding and design-related tasks.
• Strong experience working with design tools such as Figma and Adobe Creative Suite
• Proven experience contributing to software projects in a team environment, including peer code reviews, version control, and shared coding standards
• Strong written, verbal, and presentation skills, with the ability to clearly explain ideas to technical and non-technical audiences
• Strong experience building and/or consuming APIs and working with live or structured data
• Demonstrated ability to work cross-functionally with designers, engineers, product managers, and user researchers
• Comfort working autonomously in ambiguous problem spaces, from concept through execution
• Solid understanding of interaction design principles, user experience best practices, and modern design workflows
• Experience presenting and demoing work to peers, cross-functional partners, and leadership
• Experience integrating AI capabilities into prototypes, internal tools, or workflows
• Curiosity and technical fluency around AI models, APIs, and limitations, with an emphasis on practical application over theory
• Experience developing Figma plugins and working with the Figma API
• Experience working with video content or media-rich interfaces
• Familiarity with modern frameworks and languages such as TypeScript, Next.js, or LightningJS
• Experience with platforms and tools such as Node.js, GraphQL, GitHub, AWS, Azure, GCP, Cloudflare, Firebase, Mixpanel, Contentful, Vercel, Xcode, and Apache

Responsibilities

• Partner closely with designers, product managers, engineers, and user researchers to build prototypes that support design exploration, usability testing, experimentation, and stakeholder alignment
• Rapidly translate abstract ideas and early concepts into interactive, high-fidelity prototypes across web, mobile, and TV platforms
• Design and build internal tools, utilities, and Figma plugins that improve design quality, consistency, speed, and scalability
• Explore and apply AI-driven approaches to design, prototyping, automation, content exploration, and workflow optimization
• Integrate live or simulated data into prototypes by building or consuming APIs
• Improve and evolve initial design concepts through iterative prototyping and feedback
• Build and maintain shared toolkits, frameworks, and codebases that accelerate prototyping across the team
• Take technical and creative ownership of projects, including starting new frameworks, tools, or experimental codebases from scratch
• Stay current with industry trends, emerging interaction patterns, and new technologies, and proactively apply them where they create leverage
• Continuously look for opportunities to improve how the team prototypes, experiments, and collaborates
• Mentor and support other design engineers, helping raise the bar for craft, technical quality, and impact across the team
