This role spans a broad spectrum of activities: Architect high-performance infrastructure for training large-scale models and running complex simulations. Design and optimize custom RL environments informed by neuroscience. Write clean, fast, production-grade code that boosts our research velocity. Turn research prototypes into scalable production systems. Tackle any technical bottleneck, from low-level optimization to high-level system design, to unblock the research team. Qualifications High-Velocity Craftsmanship: You produce clean, maintainable, and well-tested code at a startup pace. You know how to balance engineering rigor with the need to iterate quickly on research prototypes. System Architecture Intuition: You have deep experience architecting complex systems from scratch. You understand the trade-offs, and you can design infrastructure that survives the chaos of research. Extreme Adaptability: You might be an expert in distributed systems today, but you are ready to become a novice in neuroscience tomorrow. You have a track record of diving into complex domains and mastering them quickly. Mastery of Hard Problems: You have a track record of tackling difficult engineering challenges, whether it is massive scale distributed systems or low-level optimization. You do not shy away from what your peers consider hardcore. Location & Visa This role is in-person in Emeryville, CA. Visa sponsorship may be available for qualified candidates.
