Senior Product Designer

What we're building Mutiny is the self-improving AI infrastructure for GTM teams to execute faster and close more revenue. Our ambition is to do for revenue velocity what Cursor and Claude Code did for engineering velocity. With Mutiny, everyone in sales and marketing gets a bench of GTM athletes that handle any work across their revenue motion and learn from what's actually moved their deals. In April we re-launched the product as an agent-first platform. Anthropic showcased us as a leader in AI GTM. MRR is growing more than 70% month-over-month, with customers like Uber, Rippling, and Snowflake. We're backed by Sequoia, YC, and Insight, and we're building a generational company. The opportunity Most design hires inherit a system. You'll build it. As a founding designer, you'll partner with the founders and engineering to define how Mutiny looks, feels, and behaves, from the first interaction with the creative agent to the final published asset. They have high standards and strong opinions and you'll hear from them constantly. The patterns you set become the shared language for what AI-native GTM software feels like. This role is in person in New York City, five days a week. What you'll own The end-to-end product. From the first interaction with the creative agent to the final published asset. Design new surfaces, rethink existing ones, and figure out which tedious parts of GTM work AI should take over so customers spend their time being strategic. The creative agent's output. The work the agent produces matters as much as the surface around it. Partner with engineering on better defaults, smarter constraints, and stronger adherence to brand guidelines. An AI that's genuinely creative and knows how to color inside the lines when it needs to. Taste as a system. Curate what good looks like. Build the feedback loops that make the model's output sharper every week. Decide what ships and what doesn't. The design system. Components, patterns, and guardrails that let product and engineering ship well-designed work without you in the room. Quality at speed, including the internal tools that make the team faster. Product strategy. You're not a feature receiver. You're in the room shaping what we build, pushing back when something doesn't feel right, and pulling engineers into design conversations before there's a screen to react to. Who you are Shipped, not just shown. You've taken ambiguous problems, found the right shape, and shipped something people use. The quality of your thinking matters more than the logos on your resume. A point of view on AI and creativity. You've thought about where AI should lead and where humans should steer. You can name what makes AI-generated work feel good versus feel generic. These questions excite you, not intimidate you. Obsessive about craft. You sweat the 4px decisions. You won't ship something that's "fine" because fine compounds badly. Your work feels thought-through to the last pixel. A builder. You prototype, you ship, you iterate. You vibe code side projects, your AI toolkit is broad, and you'd rather make a thing than write a brief about it. A systems thinker. You see patterns across features and create the shared foundations that make everything better. You're not solving one screen at a time. You sharpen the room. Design here isn't a service org. You shape product strategy, push back when something doesn't feel right, and pull engineers into design conversations before there's anything to react to.
