[Hiring] Staff Software Engineer, Core Canvas @Mural

Role Description

As a Staff Software Engineer, you’ll play a key role in shaping the technical direction of the Canvas platform and ensuring the Mural editor is reliable, high-performing, and intuitive for our users.

• Help design and maintain systems that power real-time collaboration, shared document editing, spatial interactions, rendering and interaction performance, asset management, developer APIs, and AI-enabled product capabilities.
• Reduce platform complexity, improve the quality and speed of Canvas development, and help teams ship high-quality editor experiences quickly and safely.
• Partner closely with Product, Design, Engineering, and other stakeholders to turn ambiguous product and platform problems into high-quality technical solutions.
• Lead, design, and implement complex technical projects that affect multiple teams.
• Contribute to team, department, and company-wide engineering standards, processes, and culture.
• Provide mentorship and support for other engineers.

Qualifications

• Fluency in modern JavaScript/TypeScript, with familiarity in React, Node.js, or comparable modern frameworks.
• 10+ years building and shipping large-scale production software as part of an agile engineering team.
• Systems architecture judgment, with a track record of delivering scalable, reliable, high-performance systems and developer-facing abstractions that balance simplicity, developer experience, and long-term maintainability.
• Experience designing clean API contracts and service boundaries, including thoughtful data models, versioning, validation, error handling, documentation, and long-term maintainability.
• 3+ years building distributed, concurrent, or real-time systems, such as collaboration tools, MMO games, shared-state systems, messaging protocols, or other low-latency user experiences.
• Strong background architecting complex systems with rich object models, including hierarchical scene or document structures, spatial indexing and querying, layout behavior, asset management, selection mechanics, and performance-sensitive user interactions.
• A track record of building or integrating AI-enabled product capabilities in production.
• Performance optimization expertise, including profiling, bottleneck analysis, memory and CPU efficiency, latency reduction, and responsiveness as document complexity and user activity scale.
• Familiarity with parallel processing, off-main-thread architectures, rendering pipelines, background computation, or other multithreaded systems is a plus.
• A practical, outcome-oriented approach to AI-driven development practices.
• Proven technical project leadership, including planning and delivering new systems and features iteratively with a focus on customer value.
• Communication and collaboration skills, with a low-ego approach to working with Product, Design, and Engineering.
• Comfort operating in high-growth, fast-paced environments or scale-ups is a plus.

Requirements

• Elevate the team’s skills and knowledge through technical design reviews, demos, code reviews, mentoring, and improvements to team, department, and company-wide engineering standards, processes, and culture.
• Build and evolve complex canvas systems with rich document and object models.
• Work on large-scale concurrent and real-time collaboration systems.
• Design, build, and integrate AI-enabled product capabilities.
• Improve performance through profiling, bottleneck analysis, architectural simplification, targeted optimization, and moving expensive work out of critical interaction paths.

Benefits

• Equal Opportunity: We will ensure that individuals with disabilities are provided reasonable accommodation to participate in the job application or interview process.
