• Present and disseminate research results at scientific conferences and in peer-reviewed publications.

• M.S. in Computer Science, Applied Mathematics, Statistics or related field or the equivalent combination of education and related experience.
• Experience in at least one machine learning research area, such as, foundation models, representation learning, safety & robustness, uncertainty quantification, interpretability, physics-constrained ML, or graph-based learning as demonstrated in software artifacts or publications at high impact AI/AL focused venues.
• Experience developing, implementing, and applying advanced statistical or machine learning models and algorithms using modern software libraries such as PyTorch, TensorFlow, or similar as evidence through medium to large scale deep learning models and experiments.
• Experience in working with diverse teams to solve complex problems and deliver practical solutions.
• Comprehensive analytical and problem-solving skills necessary to craft creative solutions and solve complex problems.

In Addition, at the SES.3 Level

• Ph.D. in Computer Science, Applied Mathematics, Statistics or related field or the equivalent combination of education and related experience.
• Demonstrated research productivity, as documented by publications, reports, presentations, and/or open-source software in high impact AI/ML focused venues, such as, NeurIPS, ICML, ICLR, CVPR, AAAI, AISTATS, UAI, KDD, or JMLR
• Advanced verbal and written communication skills necessary to interact with a multi-disciplinary research team, author technical and scientific reports and papers, and deliver scientific presentations.

Desired Qualifications

• Experience with high-performance computing, GPU programming, parallel programming, cloud computing, and/or related methods including running numerical simulations or complex workflows.
• Experience in working with subject matter experts in one or more areas, such as physics, biology, or engineering.
• Background in statistics, applied mathematics, or related area.
