Senior Machine Learning Engineer

SENIOR MACHINE LEARNING ENGINEER Location: San Francisco ABOUT HUM.AI http://Hum.ai Hum.ai http://Hum.ai is building planetary superintelligence. Backed by top funds, we’ve raised $10M+ and are now heads down building. Join us at the cutting edge, where we’re scaling generative transformer diffusion models, designing next-gen benchmarks, and engineering foundation models that go far beyond LLMs. You’ll be at the core of a moonshot journey to define what’s next in agentic AI and frontier model capabilities. We are looking for an experienced Senior Machine Learning Engineer who is eager to advance the frontier of AI, help us design, build, and scale end-to-end novel foundation models, and leverage their hands-on experience implementing a wide range of pre-training and post-training models, including large foundation models (beyond just LLM fine-tuning). This role is focused on: - Designing, implementing, and scaling state-of-the-art models - Productionizing research codes, models and technologically complex systems - Shaping benchmark design and model evaluation frameworks - Building agentic AI capabilities and long-term technical bets WHO ARE WE? Hum is a seed-funded startup on a mission to create positive impact through earth observation and AI. Founded at the University of Waterloo by a team of PhDs and engineers, we’re backed by some of the best AI and climate tech investors like HF0, Inovia Capital and Propeller Ventures, angels like James Tamplin (cofounder Firebase) and Sid Gorham (cofounder OpenTable, Granular), and partners like Amazon AWS and the United Nations. WHAT DO WE DO? We’re building multimodal foundation models for the natural world. We believe there’s more to the world than the internet + more to intelligence than memorizing the internet. Our models are trained on satellite remote sensing and real world ground truth data, and are used by our customers in nature conservation, carbon dioxide removal, and government to protect and positively impact ou
