Senior Software Engineer, Canvas Core

About the role

The Canvas Core team builds and maintains the foundational platform that powers Mural's visual thinking experience, including the infinite canvas, real-time collaboration, and developer-friendly APIs. As a Senior Software Engineer, you will design, build, and improve these systems to ensure the editor remains reliable, high-performing, and intuitive. You will partner with cross-functional teams to turn complex technical problems into maintainable solutions while mentoring team members and raising engineering standards.

Responsibilities

• Own and deliver new Canvas platform capabilities and improvements from problem definition through implementation, release, measurement, and iteration
• Partner with Product and Design to shape high-quality user experiences, balancing pragmatic technical delivery with long-term platform needs
• Design and build maintainable Canvas platform systems, with accountability for quality, performance, reliability, and developer experience
• Contribute to developer-friendly APIs, service boundaries, and platform contracts that internal teams can build on quickly and safely
• Use AI-assisted tools and agentic workflows as part of your engineering practice to prototype, implement, test, document, and measure work effectively
• Strengthen the team through technical design reviews, demos, code reviews, mentoring, and improvements to engineering practices
• Build and evolve canvas systems with rich document and object models, including hierarchical scene or document structures, spatial indexing and querying, layout behavior, asset management, and selection mechanics
• Work on large-scale concurrent and real-time collaboration systems that keep shared documents synchronized across users, contributing to design decisions around event ordering, latency, conflict handling, and failure-mode management
• Help design, build, and integrate AI-enabled product capabilities where they intersect with the canvas, document model, real-time collaboration systems, or developer platform
• Improve performance through profiling, bottleneck analysis, architectural simplification, targeted optimization, and moving expensive work out of critical interaction paths so systems remain responsive as document complexity and user activity scale
