US H-1B: cap-subject employers enter a lottery weighted by wage level — Level I gets 1 entry, Level IV gets 4 (DHS projected selection odds ≈15% at Level I to ≈61% at Level IV). Universities and non-profit research employers are cap-exempt. The $100,000 fee for new petitions from abroad is currently blocked by a court order (appeal pending).

About the role: Multi-Agent systems are becoming an increasingly important part of how AI is deployed, whether via fast small-model subagents inside a product, or large groups of agents solving very large problems . Training Claude to be maximally effective and safe within large groups is a challenging new area of reinforcement learning, and represents a new axis for scaling test time compute. We are looking for researchers who have experience training multi-agent systems at the largest scale and an appreciation for the incentives and mechanism design that come into play. Responsibilities: • Help create and optimize environments and data for model training that maximize Claude’s performance or ease of use on agentic tasks • Ideate, develop, and compare the performance of different agent harness configurations (eg memory, context management, communication architectures for agents) • Design and implement rigorous quantitative benchmarks for large scale agentic tasks • Work with our product org to find solutions to our most vexing challenges in applying agents to our products You may be a good fit if you: • Have experience with large-scale RL on language models • Have experience training multi-agent systems • Enjoy going deeply into the roots of a problem and understanding its foundations, rather than its surface. • Have good communication skills and an interest in working with other researchers on difficult tasks • Have a passion for making powerful technology safe and societally beneficial • Are excited for a mission-driven org with fast-paced, impactful work Representative projects: • Design and build reinforcement learning environments to train groups of Claudes how to solve problems together efficiently • Design and build agent affordances that unlock new capabilities and scales of agents, while keeping the Bitter Lesson in mind • Design and build a novel eval that measures how large teams of agents interact in groups to solve problems The annual compensation range for this role is listed below. For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role. Annual Salary: $500,000 — $850,000 USD Logistics Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position 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. 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 w
