Job Title Founding Designer Salary Not Disclosed + Equity Company Description Balderton-backed AI music startup making studio-quality creation universal

You will own design end-to-end for a breakthrough music platform, bridging the gap between a pro-grade studio tool and a viral consumer creator product. Working alongside the founders in London, you'll leverage AI-native workflows to ship branding, design systems, and frontend code that defines the future of musical expression. Location London, UK Why this role is remarkable

• Join a tier-1 venture-backed team (Balderton) as the first design hire, owning up to 0.8% equity and defining the entire visual and creative identity of the brand.
• Solve a unique dual-mode design challenge, building a product that serves both "tourist" casual creators and professional bedroom producers without compromising on power or accessibility.
• Ship at extreme velocity using an AI-native toolchain (Cursor, Claude Code), where your designs move from Figma to production in hours rather than weeks. What You Will Do
• Execute a full consumer rebrand and ship a unified design system across product, marketing, and motion within your first 60 days.
• Run at least four design-led cohort experiments per month, using data and first-principles thinking to drive signups, activation, and paid conversions.
• Directly bridge the design-to-code gap by writing React and Tailwind CSS, ensuring every pixel in production perfectly matches your high-fidelity interactive prototypes. The ideal candidate
• A consumer-focused designer with a portfolio of emotional, high-engagement brands (e.g., Spotify, Instagram) rather than B2B SaaS or administrative dashboards.
• An AI-native power user who treats tools like Cursor and Claude as a core part of their design discipline to ship frontend code and interactive prototypes quickly.
• A musician, producer, or beatmaker who speaks the language of creators and possesses deep intuition for what makes music-making tools feel fun and approachable. === Who are Jack & Jill?
