As ComfyUI’s Frontend Tech Lead Manager, you will shape our user interface and lead a team of frontend engineers. You will own the architecture and development of our core UI, ensuring ComfyUI’s interfaces are fast, robust, and user-friendly. You will remain technically hands-on where it adds leverage, while focusing primarily on architecture, technical direction, and team leadership. In short, you will help define the future of ComfyUI’s frontend experience from prototyping new ideas to shipping polished releases.
What you’ll do
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.
Technical leadership: Contribute to key technical and product decisions as part of the leadership/engineering team. Drive architectural discussions and ensure alignment across the stack.
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.
Must-have experience
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.
Comfy (https://www.comfy.org) is the AI creation engine for visual professionals who demand control over every model, every parameter, and every output. The most powerful workflow engine for visual AI.
Unlike tools that hide everything behind a prompt box, Comfy lets you connect models, processing steps, and outputs on a canvas where every decision is visible and every step is inspectable. It gives you the building blocks to create workflows nobody's imagined yet, and share them with everyone.
What started as an open-source project in 2023 now has 4 million users, 60,000+ community-built nodes, and 150,000+ daily downloads. It's used by artists, filmmakers, game studios, designers, researchers, and VFX houses, including teams at OpenAI, Netflix, Amazon Studios, Ubisoft, EA, and Tencent.
We're a small, intense team in San Francisco. Our team comes from Stability AI and Google, and many contributed to the ComfyUI ecosystem long before working here. Low ego, high ownership. We work hard and demand a lot of each other, but we have fun. Everyone here is building something meaningful that will end up being our life's work.
If this mission excites you and you view yourself as top-tier talent, your future latent self is waiting for you at Comfy.
Check out our Github (https://github.com/comfyanonymous/ComfyUI) and blog (https://blog.comfy.org). We recently raised $30M at a $500M valuation. The round was led by Craft, with participation from Pace Capital, Chemistry, TruArrow, and others.
