Job description
from Baseten careersABOUT BASETEN
Baseten powers mission-critical inference for the world's most dynamic AI companies, like Cursor, Notion, OpenEvidence, Abridge, Clay, Gamma and Writer. By uniting applied AI research, flexible infrastructure, and seamless developer tooling, we enable companies operating at the frontier of AI to bring cutting-edge models into production. We're growing quickly and recently raised our $300M Series E, backed by investors including BOND, IVP, Spark Capital, Greylock, and Conviction. Join us and help build the platform engineers turn to to ship AI products.
THE ROLE
This role sits at the frontier of our research agenda. You will pursue open problems at the intersection of post-training methodology and performant inference and then collaborate with research engineering to translate findings into production systems. Roughly a third of your time will be dedicated to pure research: questions that may not have immediate product application but deepen our understanding of models ability to learn, alignment, or architectural efficiency. The remainder will be directed toward research that solves concrete training problems for Baseten's platform and customers which are the fastest growing AI companies in the world like Cursor, Lovable, Notion etc.
