In short, you will help define the future of ComfyUI’s frontend experience from prototyping new ideas to shipping polished releases.

Requirements

• Engineering leadership: 6+ years of software engineering experience, including several years in a senior role (Tech Lead or Engineering Manager). Proven track record leading or mentoring engineering teams in a fast-paced environment.
• Shipping large-scale apps: Demonstrated experience building and shipping complex, high-performance web applications (and preferably cross-platform desktop apps). You’ve taken products or features from 0→1 to production, serving real users at scale.
• Frontend expertise: Deep expertise with modern frontend frameworks and languages in our stack - Vue 3, Typescript, (plus Vite, Tailwind, Electron, etc.)
• Performance & UX: Strong understanding of UI/UX principles. You know how to build fast, responsive, and accessible interfaces. You pay attention to the details (animations, layouts, interactions) that make a UI feel refined.
• Tooling & processes: Hands-on experience with frontend build tools, module bundlers, and modern development workflows. Comfortable setting up and managing CI/CD pipelines, automated testing, and code review processes. Familiarity with tools like Vite, Nx, Jest, Playwright, or similar is valuable.
• Ownership & communication: Excellent communication and collaboration skills. You take ownership of your projects, can articulate technical ideas clearly, and drive initiatives end-to-end. You thrive in a small team where everyone wears multiple hats.
• Passion & mindset: A startup mindset – you thrive in fast-moving environments, love solving hard problems, and are willing to roll up your sleeves wherever needed. You care deeply about building a great product and enjoy working closely with teammates who are just as passionate.

Responsibilities

• Lead frontend architecture: Drive the design and development of ComfyUI’s core frontend systems from the ground up. Set the long-term vision for how our interface is structured and evolves.

• Mentor & grow the team: Mentor and manage frontend engineers, fostering a high-caliber team and strong engineering culture. Help recruit, hire, and onboard new members.
• Define best practices: Establish and enforce best practices for frontend code quality, testing, performance, and maintainability. Maintain, evolve, and improve our CI/CD and automated testing process to keep our front-end rock-solid as we scale.
• Collaborate cross-functionally: Work closely with Product, Design, Backend, AI/ML to shape the end-to-end user experience. You’ll translate complex requirements into elegant interfaces and connect the frontend to our generative AI pipelines.
• Project planning & execution: Oversee project execution by setting timelines, prioritizing tasks, and ensuring timely delivery of frontend milestones. Balance short-term goals with long-term technical health.
• Prototype & iterate: Rapidly build and iterate on UI features to test new concepts, validate user flows, and ensure a polished end-user experience. You’ll turn product ideas into working prototypes and refine them into production features.
• Stay on the cutting edge: Keep up-to-date with the latest frontend technologies and trends. Evaluate new tools, libraries, or approaches (e.g. improvements in Vue.js, TypeScript, tooling like Vite/Nx, or UI frameworks) to keep ComfyUI’s frontend modern and scalable.
• Quality & optimization: Identify and troubleshoot frontend performance bottlenecks. Optimize for speed, responsiveness, and accessibility across our UI. Advocate for users and ensure that every interface feels polished and intuitive.
