• Create a world-class creative tool and workflow engine • Architect and implement foundations that power engineering organization • Write shared abstractions that are extensible for future changes • Design data models evolved in an open source environment • Introduce new core types, such as VIDEO or 3D • Partner with product design and frontend engineers to ship user-facing features

• You will be a core contributor to ComfyUI Desktop, the native application that brings one of the most popular open source AI projects to millions of users on Windows, and macOS. • Your mission is to make that first moment magical. When someone downloads ComfyUI, you're the reason it just works. • You'll build the native experience that transforms a powerful but complex tool into something that feels effortless. • Example projects include… - Building a seamless installation and onboarding experience that installs Python environments for all operating systems and GPUs supported by ComfyUI - Designing a system to back-up a user's files (models, custom nodes) to be accessible from any environment - Implementing a way to manage multiple ComfyUI environments - Smoothly integrating the desktop application with ComfyUI Cloud to unlock hybrid usage

• Lead and develop a distributed team of 8+ engineers across Identity Management, Payments & Billing, and Internal Admin Platform; spanning junior to senior-level talent • Drive engineering execution: sprint planning, technical prioritization, and delivery across multiple concurrent workstreams • Engage deeply with the PHP monolith; code reviewing, architectural decision-making, and guiding incremental modernization without disrupting production systems • Build and maintain a high-performance team culture through 1:1s, career development, and structured feedback loops • Partner closely with product, design, and adjacent engineering leadership to align on roadmap priorities and technical strategy • Develop team processes that balance velocity, quality, and operational stability at scale • Own hiring and headcount planning for your teams, including defining roles and evaluating candidates • Perform technical risk assessments and guide teams through complex system changes; including IAM/SCIM integrations, billing infrastructure, and account lifecycle work

• Design and build reliable, well-documented RESTful APIs consumed by internal teams and external customers at scale • Navigate and extend a large, mature PHP monolith… understanding existing patterns, respecting stability, and improving incrementally • Identify and address technical debt in a principled way, balancing immediate delivery needs with long-term maintainability • Integrate and maintain third-party SDKs and external services, ensuring reliability, error handling, and graceful degradation • Write clean, testable code that meets and elevates team coding standards… leaving every surface better than you found it • Collaborate closely with engineering peers and leads to review code, share context, and raise the technical bar across the team • Debug and resolve production issues across a complex, interconnected system… quickly, thoroughly, and with clear communication • Contribute to architectural discussions and help evaluate technical tradeoffs as systems evolve
