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.
Come work with us!
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.

Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.
Research Scientist, Discovery (Engineering & Applied Sciences)
About the Team
Our team is organized around the north star goal of building an AI scientist – a system capable of solving the long term reasoning challenges and basic capabilities necessary to push the scientific and technological frontier.
About the role
On the Discovery team at Anthropic, we're expanding our work on engineering and the applied sciences. Our goal is to contribute to training Claude to invent, design, and engineer across every discipline and scale, reliably and safely: new manufacturing and experimental techniques, processes, materials, devices, instruments, machines, energy systems, and factories. We want this work to accelerate science and technology and benefit people widely.
To achieve these goals, we're seeking exceptional machine learning researchers with deep expertise in training and evaluating frontier models. In this role, you'll work end to end across the model stack, developing training environments, rewards, data, and evaluations that measure and improve Claude's performance on complex engineering and scientific tasks, and carrying what works into production training runs. You'll collaborate closely with researchers, engineers, and partners across Anthropic and industry to build AI systems that can engage in all phases of research and development, and that learn from real-world feedback. A background in engineering or the sciences is a plus but not required.
Key responsibilities
Design, build, and study reinforcement learning environments, rewards, and training data that improve Claude's capabilities in engineering and the applied sciences
Create benchmarks and evaluation frameworks that measure model performance on realistic engineering and scientific workflows
Develop simulation-based training environments and verifiers, working with domain experts to validate them against real-world data
Develop approaches to long-horizon task completion, multi-agent collaboration, and complex reasoning essential for real engineering and research work
Research how models can learn efficiently from experiments and real-world feedback.
Study how environments and rewards behave in large-scale training, including robustness, calibration, and generalization, so that training produces models that are both capable and well aligned
Scale research ideas from prototype to production training runs
Collaborate with domain experts and industry partners to build and test what Claude invents, designs, and engineers, and turn that feedback into training and evaluation signal
Help chart how Claude’s engineering capabilities reach real-world use: where they matter most, what stands in the way of adoption, and how that should shape research priorities
You may be a good fit if you have:
Proficiency in Python and hands-on experience with a modern machine learning framework such as PyTorch or JAX
Hands-on experience training or evaluating machine learning models
Track record of machine learning research: forming hypotheses, designing and running experiments, and drawing sound conclusions from the results
Ability to implement your own research ideas and diagnose problems in complex systems
Ability to learn unfamiliar technical fields quickly and work productively with experts in them
Clear communication and a collaborative approach to solving problems
Excitement about improving Claude’s scientific capabilities and the downstream impact on science and technology
Commitment to developing AI that is safe and beneficial
Strong candidates may also have:
Experience with reinforcement learning and pre-training on large language models, including environment and reward design
Familiarity with large-scale language model training, evaluation, and inference pipelines
Published research or practical experience in AI for science or engineering, or in long-horizon reasoning
A degree or work experience in an engineering or applied science discipline, such as mechanical, electrical, materials, chemical, aerospace, systems, or manufacturing engineering, applied physics, or computational simulation
Experience building simulators, surrogate models, or simulation-based environments and verifiers, and calibrating and validating them against real-world data
Experience with large-scale data pipelines and technical or multimodal datasets
Demonstrated ability to work across multiple domains, such as language modeling, systems engineering, and scientific computing

For roles performing work in California:
We will consider for employment all qualified applicants, including those with arrest or conviction records or criminal histories, in a manner consistent with the requirements of applicable state and local laws, including the San Francisco Fair Chance Ordinance, the City of Los Angeles’ Fair Chance Initiative for Hiring Ordinance, the Los Angeles County Fair Chance Ordinance for Employers, and the California Fair Chance Act.
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.
Your safety matters to us.
To protect yourself from potential scams, remember that Anthropic recruiters only contact you from @anthropic.com email addresses. In some cases, we may partner with vetted recruiting agencies who will identify themselves as working on behalf of Anthropic. Be cautious of emails from other domains.

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.
Come work with us!
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.

**GigaChat увидит мир через данные, которые соберёте вы.**
За GigaChat стоит одна из крупнейших ML-команд в России, которая обучает LLM и VLM полным циклом — от претрейна до релиза. Наша команда отвечает за то, с чего начинается любая сильная модель, — за данные: мы собираем визуальный корпус претрейна — ищем источники, фильтруем и дедуплицируем сырьё, ставим эксперименты и меряем влияние на бенчмарки. Именно состав и качество претрейн-данных определяют, каким получится финальный результат, и у вас будет возможность влиять на него напрямую.
Обязанности
* ставить эксперименты: формулировать гипотезы, какие данные и в каких пропорциях улучшат модель, и проверять их: продумывать сетап и бейзлайны, запускать обучающие прогоны, по замерам решать, что попадёт в финальную смесь
* автоматизировать подготовку данных: выстраивать очистку, дедупликацию и валидацию так, чтобы любой новый датасет без ручной доводки приходил в готовый к обучению вид
* добывать редкие и дефицитные домены: обучать классификаторы и кластеризаторы, которые вылавливают ценные сэмплы из сырых данных, и нарезать корпус на чистые датасеты по таксономиям
* собирать данные разных форматов: генерация VQA, синтетические задачи, interleaved-данные — каждый формат устроен по-своему и требует своего подхода
* обрабатывать миллиарды изображений: писать распределённый код, который прогоняет пайплайны на всём корпусе быстро и стабильно
* находить слабые места в данных: разбираться, где модель проседает из-за корпуса — чего не хватает, что зашумлено или разбалансировано, — и исправлять это
* развивать контур оценки: подключать свежие бенчмарки, следить за чистотой методики и не пускать тестовые данные в обучающий корпус
Требования
**Кто нам подходит:**
Человек, который сможет провести данные от поиска источников до состава финальной смеси. Главное — умение ставить эксперименты и делать из них честные выводы. Опыт именно с VLM или LLM не обязателен: специфика осваивается быстрее, чем культура эксперимента
**Что мы хотели бы видеть:**
* хорошая база ML, твёрдое знание CV и NLP
* понимание, как данные влияют на качество модели, и привычка при странностях в метриках первым делом смотреть в данные
* уверенный Python и опыт обучения моделей на PyTorch
* умение спланировать эксперимент и довести его до вывода, которому можно верить
* самостоятельность и проактивность: берёте тему, разбираетесь, доводите до результата
**Плюсом будут:**
* опыт построения дата-пайплайнов и процессов контроля качества данных
* опыт с распределённой обработкой (Spark, Dask, Airflow, YTsaurus)
* опыт проведения ML-экспериментов на больших объёмах
* публикации на профильных конференциях.
Мы открыты к кандидатам разного уровня, и попадать во все пункты не обязательно. Если задачи откликаются — напишите нам, остальное обсудим.
Условия
**Что мы предлагаем:**
* опыт претрейна из первых рук. Команд, обучающих VLM полным циклом, в стране единицы — вы пройдёте весь путь от сырых данных до готовой модели
* вычислительные ресурсы под ваши эксперименты. Один из самых больших GPU-кластеров в России: проверка гипотезы о данных стоит обучающего прогона, и на такие прогоны вычислений у нас хватает
* инфраструктура, которая уже работает. S3, YTsaurus, Airflow, DataLens, GitLab CI, wandb — всё для данных и экспериментов на месте, время уходит на исследования, а не на обвязку
* задачи, на которые ещё нет ответа. Как собрать лучшие визуальные данные для претрейна, пока не знает почти никто в мире — разбираться предстоит в том числе вам
* короткий путь от гипотезы до модели. Данные, которые вы отберёте, и гипотезы, которые подтвердятся, уходят в обучение следующей модели — а ей пользуются миллионы людей
* комфортный современный офис рядом с м. Кутузовская
* возможность выбрать удобный график – офис/гибрид/удаленка (в РФ)
* годовая премия
* корпоративный спортзал и зоны отдыха
* более 400 образовательных программ СберУниверситета для профессионального и карьерного развития
* расширенный ДМС, льготное страхование для семьи и корпоративная пенсионная программа
* ипотека для сотрудников по дисконтной прогамме
* бесплатная подписка СберПрайм+, скидки на продукты компаний-партнеров
* вознаграждение за рекомендацию друзей в команду Сбера.
