ByteDance, San Jose, California
We are seeking an experienced Research Scientist or Engineer to help define and build the next generation of AI infrastructure. In this role, you will work at the intersection of large-scale systems, AI, and emerging hardware to design infrastructure that enables reliable, efficient, and scalable AI workloads at ByteDance.
You will work closely with tech leaders, architects, and product teams to translate evolving AI requirements into robust infrastructure architectures. The role involves identifying emerging trends in AI algorithms and systems, designing scalable system architectures, and driving innovations that improve performance, reliability, and cost efficiency across the AI stack.
We are a lean architect & research team responsible for defining the next generation of AI infrastructure at ByteDance. AI is a fast-evolving horizon — pretraining, RL, and agentic workloads each reshape the requirements faster than traditional cloud abstractions can absorb — and our team is built to keep pace rather than simply react. We approach the problem as an end-to-end AI factory: a tightly coupled production system spanning data, applications, software infrastructure, chips, energy, and the broader supply chain.
In this role, you will work at the intersection of large-scale systems, AI, emerging hardware, and the cognitive foundations of intelligent agents — including next-generation AI memory systems informed by cognitive science and psychology — designing scalable architectures and driving innovations across the full AI factory stack.
