Research Engineer, Domain Scaling

About the role

The Domain Scaling team has the goal to make Claude world-class at real-world knowledge work in domains like finance, healthcare, and legal. This is a unique role that combines executing directly on applied research and data sourcing (real-world and synthetic) to improve our models. You'll own the end-to-end process of creating RL environments for new capabilities: identifying high-value tasks, designing reward signals, managing vendor relationships, and measuring impact on model performance.

Responsibilities

•

Own the data strategy for knowledge work verticals end-to-end, from task sourcing through RL training

•

Manage technical relationships with external data vendors, including evaluation of data quality and reward design

•

Collaborate with domain experts to design data pipelines and evaluations

•

Explore novel ways of creating RL envs for high value tasks

•

Develop and improve QA frameworks to catch reward hacking and ensure env quality

•

Run generalization experiments to measure how data strategy changes improve model capabilities

•

Partner with other RL research teams and product teams to translate capability goals into training envs and evals

You may be a good fit if you

•

Have experience with fine-tuning large language models for specific domains or real-world use cases

•

Have experience with reinforcement learning, reward design, or training data curation for LLMs

•

Are comfortable managing technical vendor relationships and iterating quickly on feedback

•

Find value in reading through datasets to understand them and spot issues

•

Have strong cross-functional collaboration skills

•

Are passionate about making AI more useful and accessible across different industries

•

Are excited about a role that includes a combination of applied research and hands-on data work

Strong candidates may also

•

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.

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.

How we're different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.

The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences.
