Founded by MIT PhDs Muyang Li, Yujun Lin, and Zhekai Zhang with CMU Professor Jun-Yan Zhu, Nunchux brings together deep research expertise and production systems experience. Our work is built on nearly a decade of research from MIT and CMU, including nunchaku https://github.com/nunchux-ai/nunchaku project, whose models have surpassed 4 million downloads. We have top VC backing, and we build for enterprises and for millions of developers.\n\n \n\n\nTHE ROLE\n\nHelp Nunchux bring new image and video models to Modelverse as soon as they become available. Your focus is speed to launch: get the model running, connect it to the platform, and ship a working first version.\n\nYou will own the initial integration and the Day 1 release, working with the cloud team on deployment and with the product engineers on the API and Modelverse integration. After launch, you will hand off the further work on performance, cost, and model quality to the relevant teams. Between launches, you will maintain and extend our shared code for model integration and serving.\n\n\n\n\nWHAT YOU’LL DO\n\n - Prototype new models: Get new image and video models running quickly with the available code and weights. Run test examples and identify what each model needs for launch.\n\n - Ship the first version: Coordinate the deployment with the cloud team, and the API and Modelverse integration with the product engineers. Get the basic parameters, examples, and developer instructions ready for Day 1.\n\n - Speed up the launch process: Find bottlenecks, automate manual steps, and simplify the handoffs with the cloud and product teams. Build reusable adapters and launch scripts to reduce the work each new model takes.\n\n - Verify and hand off: Test the integration end to end, including the outputs and the error handling. Fix launch blockers, and document the known limitations for the teams that take on further optimization.\n\n - Maintain the integration platform: Between launches, fix bugs and add support for new model interfaces, providers, and modalities in our shared integration and serving code.\n\n\nWHAT YOU BRING\n\n - Image or video model experience: You have run and adapted generation models, or integrated provider APIs.\n\n - Python and PyTorch: Strong in both, and comfortable reading model code, adapting inference pipelines, and debugging model behavior.\n\n - Production systems experience: You have deployed a model or built an API integration. Comfortable working with existing serving tools, reading logs, and debugging failed requests.\n\n - Working style: Quick to learn unfamiliar model code and get a prototype working. Able to keep the first release focused, resolve launch blockers, and coordinate with teammates to ship.\n\n\nBONUS POINTS\n\n - Experience with Hugging Face, Diffusers, ComfyUI, or model-serving frameworks such as SGLang or vLLM.\n\n - Experience working with external model providers, or building a multi-model API platform.\n\n - Contributions to open-source ML or inference projects.\n\n\nWHY JOIN\n\n - Own model launches: Take new models from their first run to a release developers can use on Modelverse.\n\n - Work with new models: Get hands-on with image and video models as they ship, across providers and architectures.\n\n - Proven traction: Build on open-source work with more than 4 million model downloads, and on growing industry partnerships.\n\n - The team: Work with researchers from MIT, Berkeley, and CMU, and with industry veterans from NVIDIA, AMD, Snowflake, and Adobe.\n\n - Compensation: $170,000 to $240,000 USD base salary, plus equity and comprehensive benefits that include health insurance and a 401(k). Actual compensation will depend on relevant experience, skills, and qualifications.\n\nLocation: San Francisco, CA. 4 days in office, 1 day remote.   \n\nStart date: As soon as available   \n\nVisa: We sponsor H-1B and other work visas for exceptional candidates.   \n\nLearn more: nunchux.ai http://nunchux.ai   \n\nApply: Please apply through our Ashby careers page.\n\nNunchux AI is an equal opportunity employer.
