*   **Devinterp of language models**: Scaling up techniques like local learning coefficient (LLC) estimation to larger models and validating next-generation SLT-derived techniques for analyzing neural network structure.
*   **Near-term applications of SLT**: Investigating refined LLCs for immediate safety-relevant applications, such as measuring the reversibility of safety fine-tuning, measuring susceptibility to jailbreaking, detecting backdoors, and quantifying weight-exfiltration risk.
*   **Theoretical foundations**: Advancing our understanding of singular learning theory and its applications to AI alignment.

**Benefits and Salary**
-----------------------

Your starting salary range is USD70,000 – USD140,000, depending on prior experience and location. There may be flexibility in salary for exceptional candidates with significant experience.

Our benefits include:
