About the role
- Joining us as a Research Engineer, you'll be at the forefront of tackling one of the most critical challenges in AI today: safety and alignment.
- The Safety team is dedicated to pioneering and implementing techniques that make our models more robust, honest, and harmless.
- As a Research Engineer, you will bridge the gap between theoretical research and practical application, writing high-quality code to test hypotheses and integrating successful safety solutions directly into our products.
Responsibilities
- Develop and implement novel evaluation methodologies and metrics to assess the safety and alignment of large language models.
- Collaborate with engineering and product teams to translate safety research into practical, scalable solutions and best practices.
Requirements
- Experience working with GPUs (training, serving, debugging)
- Experience with data pipelines and data infrastructure
Nice to have
- Experience with product experimentation and A/B testing
- Experience training large models in a distributed setting
- Familiarity with ML deployment and orchestration (Kubernetes, Docker, cloud)
- Experience with explainable AI (XAI) and interpretability techniques.
- Have research in AI safety, alignment, ethics, or a related area.
- Knowledge of the broader societal and ethical implications of AI, including policy and governance.
