Senior Product Designer (Brazil)

Moises is a music creation and editing tool used by 70 million musicians worldwide. As a Product Designer, you’ll shape how musicians experience AI by designing intuitive products that help them learn, practice, and create. You will collaborate closely with Product, Engineering, AI, and Data teams to define problems and deliver engaging products.

Responsibilities:

• Own end-to-end design for major product areas, including discovery flows, core interaction patterns, and final visual execution that can span from iOS, Android, and web
• Translate complex audio AI capabilities into interfaces that feel immediate and intuitive, without exposing the complexity underneath
• Run and synthesize user research with musicians across skill levels and use cases, turning what you learn into decisions the team can act on
• Contribute to and evolve the design system, keeping it coherent and scalable across platforms
• Partner with PMs and engineers from early problem framing through to shipped feature, helping define what the problem is before designing a solution
• Give and receive direct, specific design critique that raises the quality bar for everyone working on the product

Requirements:

• 5+ years designing complex software that real people use daily, with a portfolio showing powerful technology made to feel simple
• Fluency moving between fidelities fast, from napkin sketch to coded prototype in a day, because the fastest way to settle a debate is to make the thing real
• Comfort in ambiguity and zero-to-one work: you have shipped before the problem was well-defined, without a design system, a clear spec, or a playbook to copy
• Track record of defining interaction paradigms, not just executing within them, including patterns you invented rather than iterated on
• Strong written communication: you can explain the reasoning behind a design decision as clearly as you can show it in Figma
• Proven ability to do your own research and bring it back as product direction, not just design artifacts. You talk to customers, watch how they work, and walk out knowing what to build next
• Prototypes in code as a default, not a last resort. Cursor, Claude Code, or similar tools are already part of how you work
• Experience designing AI-native products and the unique UX challenges of probabilistic systems
• Experience with music production, audio engineering, or playing an instrument
• Familiarity with DAWs, VST plugins, or other professional music software
• Experience designing cohesive experiences across multiple platforms and devices
• Motion design, interaction animation, or advanced prototyping skills
