About Anthropic

Anthropic'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 committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

About The Role

As a Research Engineer on the Model Performance team, you will help solve one of our greatest challenges: systematically understanding and monitoring model quality in real‑time. This role blends research and engineering responsibilities, requiring you to train production models, develop robust monitoring systems, and create novel evaluation methodologies.

Note: For this role, we conduct all interviews in Python.

Representative Projects

• Build comprehensive training observability systems – Design and implement monitoring infrastructure to keep an eye on how model behaviors evolve throughout training.
• Develop next‑generation evaluation frameworks – Move beyond traditional benchmarks to create evaluations that capture real‑world utility.
• Create automated quality assessment pipelines – Build custom classifiers to continuously monitor RL transcripts for complex issues.
• Bridge research and production – Partner with research teams to translate cutting‑edge evaluation techniques into production‑ready systems, and work with engineering teams to ensure our monitoring infrastructure scales with increasingly complex training workflows.

You May Be a Good Fit If You

• Are proficient in Python and have experience building production ML systems.
• Have experience with training, evaluating, or monitoring large language models.
• Are energized by the high stakes and intensity of production training, and ready to jump in wherever needed.
• Are naturally curious about debugging complex, distributed systems and thinking about failure modes.
• Enjoy collaborative problem‑solving and working across diverse teams – you'll work on virtually all stages of our model training pipeline.
• Can balance research exploration with engineering rigor.
• Have strong analytical skills for interpreting training metrics and model behavior.
• Want to directly impact the quality and safety of deployed AI systems.

Strong Candidates May Have

• Experience with reinforcement learning and language model training pipelines.
• Experience designing and implementing evaluation frameworks or benchmarks.
• Background in production monitoring, observability, and incident response.
• Experience with statistical analysis and experimental design.
• Knowledge of AI safety and alignment research.

Strong Candidates Need Not Have

• Formal certifications or education credentials.
• Academic research experience or publication history.
• Prior experience in AI safety or evaluation specifically.

We're looking for thoughtful engineers who are excited about the challenge of measuring and monitoring capabilities we're still discovering. This role offers the opportunity to shape how the field approaches model quality assessment while working on systems that will be critical as AI capabilities continue to advance.

The expected base compensation for this position is below. Our total compensation package for full‑time employees includes equity, benefits, and may include incentive compensation.

Annual Salary

$315,000—$340,000 USD

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. But 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.

Other: 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.
