Founding Designer at Mozart AI

Are you a designer who actually makes music? This Balderton-backed startup is seeking a Founding Designer to own the identity of a platform making studio-quality music creation as universal as listening. You'll move beyond static mockups to ship real frontend code using AI-native tools, building a brand that appeals to both casual creators and pro producers. With up to 0.8% equity and a mission to redefine a multi-billion dollar creative industry, this is the chance to lead design at a 10-person team moving at extreme velocity. If you're a high-output generalist who lives in Figma and Cursor, this role is for you.

Overview

Role overview

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.

Responsibilities

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.

Candidate profile

Who this is a fit for

  • 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.

What makes it remarkable

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.
