Research Scientist, Model Architectures

Zyphra is an artificial intelligence company based in Palo Alto, California.The Role:As a Research Scientist, Model Architectures, you will be a core contributor to Zyphra’s AI Architecture Research Team. This will involve designing and rigorously testing novel model architectures and training methodologies, with a focus on improving core modeling capabilities (in terms of loss per flop or loss per parameter) and solving fundamental bottlenecks in contemporary models. You will also work extremely closely with our pretraining team, who will integrate your insights into our next-generation models.What you need:Strong research taste and intuitionThe ability to work through a research project from conception to execution to write-upStrong implementation and prototyping ability can take an idea from conception to experimentation extremely quicklyThe ability to work well and cooperate with others in a high-paced research settingCuriosity, interest, and joy in understanding intelligence.Requirements:Previous experience with long-term memory, RAG/retrieval systems, dynamic/adaptive computation, and alternative approaches to credit assignmentExperience with reinforcement learning, control theory, and signal processingGenerally, a joy in inventing and seriously assessing ‘crazy’ ideas, and the ability to have a unique perspective on thingsUnderstanding of modern training pipelines and the hardware requirements to design efficient architectures for GPU hardwareStrong grasp of proper experimental methodology for running rigorous ablations and other hypothesis testingHigh proficiency with PyTorch and Python.Strong ability to jump into large pre-existing codebases and rapidly get up to speed and become productivePreviously published machine learning research in well-respected venuesPostgraduate degree in a scientific subject (Computer Science, EE/EECS, Math, Physics)Why Work at Zyphra:Our research methodology is to make grounded, methodical steps toward ambitious goals.Both deep research and engineering excellence are equally valuedWe strongly value new and crazy ideas and are very willing to bet big on new ideasWe move as quickly as we can; we aim to minimize the bar to impact as low as possibleWe all enjoy what we do and love discussing AIBenefits and Perks:Comprehensive medical, dental, vision, and FSA plansCompetitive compensation and 401(k)Relocation and immigration support on a case-by-case basisOn-site meals prepared by a dedicated culinary team; Thursday Happy HoursIn-person team in Palo Alto, CA, with a collaborative, high-energy environmentWe’re building something new, and we want someone with strong research taste and intuition.
