Research Scientist​/Engineer, Honesty

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

As a Research Scientist/Engineer focused on honesty within the Fine tuning Alignment team, you'll spearhead the development of techniques to minimize hallucinations and enhance truthfulness in language models. Your work will focus on creating robust systems that are accurate and reflect their true levels of confidence across all domains, and that work to avoid being deceptive or misleading. Your work will be critical for ensuring our models maintain high standards of accuracy and honesty across diverse domains.

• Design and implement novel data curation pipelines to identify, verify, and filter training data for accuracy given the model’s knowledge
• Develop specialized classifiers to detect potential hallucinations or miscalibrated claims made by the model
• Create and maintain comprehensive honesty benchmarks and evaluation frameworks
• Implement search and retrieval‑augmented generation (RAG) systems to ground model outputs in verified information
• Design and deploy human feedback collection specifically for identifying and correcting miscalibrated responses
• Design and implement prompting pipelines to generate data that improves model accuracy and honesty
• Develop and test novel RL environments that reward truthful outputs and penalize fabricated claims
• Create tools to help human evaluators efficiently assess model outputs for accuracy

• Have an MS/PhD in Computer Science, ML, or related field
• Possess strong programming skills in Python
• Have industry experience with language model fine tuning and classifier training
• Show proficiency in experimental design and statistical analysis for measuring improvements in calibration and accuracy
• Care about AI safety and the accuracy and honesty of both current and future AI systems
• Have experience in data science or the creation and curation of datasets for fine tuning LLMs
• An understanding of various metrics of uncertainty, calibration, and truthfulness in model outputs

• Published work on hallucination prevention, factual grounding, or knowledge integration in language models
• Experience with retrieval‑augmented generation (RAG) or similar fact‑grounding techniques
• Background in developing confidence estimation or calibration methods for ML models
• A track record of creating and maintaining factual knowledge bases
• Familiarity with RLHF specifically applied to improving model truthfulness
• Worked with crowd‑sourcing platforms and human feedback collection systems
• Experience developing evaluations of model accuracy or hallucinations

Education requirements: We require at least a Bachelor's degree in a related field or equivalent experience.

Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.

Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. If we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.

We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work.

We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team.

The expected salary range for this position is: $280,000—$425,000 USD.

Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.
