Zyphra is an artificial intelligence company based in San Francisco, California. The Role: As a Research Engineer - Brain Computer Interface Models, you will be a core contributor to Zyphra’s BCI work, building the next generation of open-source EEG and brain–computer interface models. You will be involved across the full model lifecycle, from data collection and preprocessing to designing novel architectures and training methodologies. You’ll Work Across: • Large-scale EEG model training runs and evaluation • Architecture and training methodology ablations and innovations • Dataset collection and preprocessing for EEG and other BCI modalities • Performance optimization of the training stack • Integration of models into real-world BCI applications What We're Looking For / Requirements: • Organized, methodical researcher who can take ownership of a project component, communicate their process clearly, and deliver a working module • Excellent communication and collaboration skills, with clean and concise coding practices • Strong implementation and prototyping skills, with comfort working across both research and engineering at scale • Ability to learn new domains quickly, orient oneself in the academic literature, and implement new ideas, creatively borrowing concepts from other modalities and applying them to EEG domain • Interest in neural data such as EEG, MEG, fMRI as well as building foundation models in a much less explored space • Proficiency with PyTorch and Python Qualifications / Additional Skills: • Experience with VAEs, GANs, diffusion models, and contrastive learning • Familiarity with signal processing (especially for EEG) and time-series analysis • Experience training on large-scale (multi-node) GPU clusters • Experience contributing to large existing codebases and ramping up quickly • Previously published machine learning research in well-respected venues Why Work at Zyphra: • Our research methodology is grounded in methodical, step-by-step approaches to ambitious goals. Both deep research and engineering excellence are equally valued • We strongly value new and crazy ideas and are very willing to bet big on new ideas • We move as quickly as we can; we aim to minimize the bar to impact as low as possible • We all enjoy what we do and love discussing AI Benefits and Perks: • Comprehensive medical, dental, vision, and FSA plans • Competitive compensation and 401(k) plan • Relocation and immigration support on a case-by-case basis • In-office snacks and meals provided • Unlimited PTO and company holidays • In-person team in San Francisco with a collaborative, high-energy environment
