Research Engineer, Model Evaluations

About the roleWe are looking for Research Engineers to build evaluations for our Claude family of Large Language Models. Your job will be to design and implement evaluations that allow Anthropic researchers and decision makers, and members of the public, to understand Claude’s abilities and personality.  We aim to produce extremely well-benchmarked large language models with known performance on a wide range of tasks, turning ambiguous notions of “intelligence” into clear metrics.  
About AnthropicAnthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

You may be a good fit it you:

• Have significant Python programming experience / machine learning research 
• Are excellent at data visualization
• Have experience using Large Language Models such as Claude
• Are results-oriented, with a bias towards flexibility and impact
• Pick up slack, even if it goes outside your job description
• Enjoy pair programming (we love to pair!)
• Want to learn more about machine learning research
• Care about the societal impacts of your work
• Have clear written and verbal communication

Strong candidates may also have experience with:

• Building user interfaces for data analysis
• Developing robust evaluation metrics for language models
• Handling textual dataset sourcing, curation, and processing tasks at scale
• Statistics

Representative projects:

• Designing and running a new evaluation that tests Claude’s reasoning capabilities, and creating a compelling visualization that illustrates the results
• Running experiments to determine how prompting techniques affect results on industry benchmarks
• Improving the tooling that researchers use to implement evaluations
• Explaining our evaluations and their results to internal decision makers and Stakeholders
• Collaborating with a research team to develop a robust evaluation for a new model capability they are developing

LogisticsLocation-based hybrid policy: Currently, we expect all staff to be in our office at least 25% of the time.
Deadline to apply: None. Applications will be reviewed on a rolling basis.US visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate; operations roles are especially difficult to support. But if we make you an offer, we will make every effort to get you into the United States, 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.
