ResponsiveAds Senior UI/UX Design Developer

ResponsiveAds is an advanced creative ad technology suite producing fully-fluid responsive ads that outperform IAB engagement benchmarks by 20x. Our patent-protected runtime engine adapts a single creative tag to any slot, screen, or environment without re-trafficking. We are looking for a rare individual who bridges senior UI/UX design, front-end development, and AI-assisted asset workflows, someone who can own the experience layer of Creative Studio 4 and the integrations that connect it to the tools designers live in every day.

You will partner closely with our development team as well as the other product managers/designers while you drive the AI design system, plugin panel UX, asset bridge, AI ingestion interface, and stock library integration. This is not a ticket queue, it is real ownership in a lean, high-trust startup.

What You Will Do

• Own the UX design and front-end build unique AI, Agentic driven projects; the preview, asset mapping, and live push experience
• Design the asset bridge UX: layer-to-element mapping, version history, and one-click push to live ad
• Build the AI ingestion UX: upload, validate, classify, and pass AI-generated assets and models (e.g. Claude Design, Nanobanana, ChatGPT, Runway, Firefly) to the CS4 layout engine
• Design the brand-safe stock library experience (Getty, Adobe Stock, etc..) embedded directly inside the CS4 builder
• Maintain and evolve the CS4 design system with the product team; components, interaction patterns, and visual language across all surfaces
• Bring product thinking to integrations: synthesise user feedback, write lightweight specs, and help sequence the roadmap
• Run usability testing with designers and agency teams to validate concepts before full engineering investment
• Be the internal champion for the designer perspective across every product decision

Skills & Tools

• Expert Figma ; design, prototyping, and component library management
• HTML5, CSS3, JavaScript ; able to build interactive prototypes and production UI components. Hand coding, vibe coding.
• Working knowledge of SVELTE ; enough to contribute UI components directly to the CS4 codebase
• Adobe CC (Photoshop, After Effects) used professionally, not just academically
• Familiarity with AI creative tools (Firefly, Runway, Midjourney) used in a real production workflow
• REST API fundamentals; comfortable working with developers on data flow between systems
• Stock library API experience (Getty, Adobe Stock) is a strong plus
• HTML5 ad production or rich-media format experience is a significant plus
• Highly innovative, award-winning attitude; great communicator, customer-first, startup-ready

If you have strong opinions about interaction design, build prototypes before slide decks, and can talk Photoshop layer structures and CSS animation in the same breath — we want to hear from you.
