ABOUT THE TEAM At Mural, we’re reimagining how teams think and create together. The Design and Research team brings clarity to complexity, shaping experiences that help people collaborate, ideate, and solve problems visually. We partner deeply with engineering, product, and research to invent the next generation of collaborative work combining craft, systems thinking, and bold exploration. YOUR MISSION As a Lead Product Designer focused on Growth, you’ll define how Mural earns user trust at the moments that matter most when someone first encounters the product's value, decides to go deeper, or chooses to stay. This is end to end growth journey ownership. It's about designing the logic of how Mural grows: the moments where clarity converts, where friction is a design failure, and where the line between growth and product quality either holds or breaks. You'll work across discovery, activation, and pricing surfaces, onboarding paths, upgrade flows, lifecycle touchpoints, and in-product nudges. Most importantly, you'll orchestrate how those surfaces work together and set the standard for how growth design is practiced at Mural. You'll succeed if you can bring full journey thinking, rigor and craft to a domain that often defaults to shortcuts and if you can help a cross-functional team understand what good growth design actually looks like. WHAT YOU'LL DO Player Responsibilities (Individual Contributor Work): Define high-quality, user-centered discovery, activation, and monetization experiences across problem to success flows, upgrade flows, pricing surfaces, and lifecycle touchpoints — setting patterns that scale across the platform. Work from concept to production, delivering thoughtful UX, polished visual design, and vibe coded prototypes that help the organization understand direction, risk, and value. Use behavioral data as a primary design input: interpret funnel metrics, experiment results, and user signals to inform design decisions, not just validate them. Desi

ABOUT THE TEAM The Canvas Core team builds and maintains the foundational platform that powers Mural’s visual thinking experience. This includes the infinite canvas, key editor components, document editing behaviors, asset management, real-time collaboration, and the systems that enable fast, reliable, and intuitive interaction on the canvas. We’re also responsible for the Mural UI, the real-time message protocol that enables seamless remote collaboration, and the developer-friendly APIs that internal teams use to build features like diagramming, workshops, presentations, integrations, and AI-enabled product capabilities. Our mission is to ensure the Mural editor is fast, reliable, intuitive, and easy to build on. We prioritize performance, simplicity, developer experience, and platform quality, enabling teams across the company to ship quickly and safely on top of Canvas Core. YOUR MISSION As a Senior Software Engineer, you’ll help design, build, and improve the Canvas platform so that the Mural editor remains reliable, high-performing, and intuitive for our users. You’ll work on the systems that power real-time collaboration, shared document editing, spatial interactions, rendering and interaction performance, asset management, developer APIs, and AI-enabled product capabilities across the Mural editor. Your role will be to reduce platform complexity, improve the quality and speed of Canvas development, and help teams ship high-quality editor experiences quickly and safely. You’ll partner closely with Product, Design, Engineering, and other stakeholders to turn ambiguous product and platform problems into clear, maintainable technical solutions. Senior Engineers at Mural lead by example through strong technical execution, thoughtful design, high-quality implementation, and collaborative problem-solving. They help raise the bar for their team through design discussions, code reviews, mentoring, documentation, and pragmatic improvements to engineering practices. WHA
