Post-Training Research Scientist

We are looking for someone with sharp research taste and genuine creative instinct for problem selection. Someone who can identify questions that matter, design clean experiments to answer them, and push the state of the art. The environment here is not theoretical, but rather research that can be validated with eager customers who are serving billions of tokens a second.

- Towards infinite context windows: neural KV cache compaction

- Distillation without the dark - replicating black-box on-policy distillation on Baseten

- Define and pursue a research agenda spanning both foundational and applied work, with the applied component connected to Baseten's platform and customer needs.

- Design and execute rigorous experiments, frequently at meaningful scale (multi-node, trillion parameter models).

- Work with customers to translate domain-specific requirements into research problems, where relevant to your agenda.

- Publish at top venues (NeurIPS, ICML, ICLR) and establish Baseten's research presence.

- Collaborate with model performance and training infrastructure teams to bridge research findings and inference production systems.

- Mentor junior researchers and shape the technical direction of the research organization as it grows.

- Master's or PhD research depth in machine learning, with first-author publications at top venues

- Demonstrated ability to move from theory through implementation to empirical results - not exclusively theoretical or exclusively engineering work

- Judgment about problem selection, the ability to distinguish research that advances a metric from research that changes how systems are built

- Willingness to operate in a startup environment where the majority of research informs product decisions, with timelines measured in months rather than years

- Background spanning multiple research areas (e.g., both interpretability and RL, or both systems and training methodology)

- Track record of open-source contributions or community building in ML research

Many of the labs that exist today run a credentialist talent model. Concentrate the most already-legible researchers, and assume the concentration compounds. The best researchers in this field are very often not yet legible.

Research engineers who have spent years inside a production stack and developed insights no PhD program teaches; PhDs working on the wrong-shaped problem at the right-shaped lab; operators who have been close to real systems long enough to see things credentialed researchers have never had to see. If you don't have the traditional qualifications and are doing exceptional work, we'd love to chat.
