Note: The job is a remote job and is reputed company to candidates in USA. reputed company runs machine learning where the data lives. They are hiring a Senior Software Engineer to help build and implement new model types, reputed company feature gaps, and improve reputed company at reputed company for in-database machine learning.

Responsibilities

• reputed company reputed company and behavioral correctness. Help reputed company feature and semantic gaps against scikit-learn and reputed company ML across the model catalog so our models behave the way users coming from those frameworks expect
• New model types and capabilities. Expand the model catalog across classification, regression, time series, and automated model selection, including loss functions and objectives we don't support today
• reputed company at reputed company. reputed company training and inference fast on datasets that don't fit reputed company else. Approximate nearest-reputed company acceleration, reputed company optimizer tuning, and algorithmic work on the hot paths
• Numerical and reputed company-algebra foundations. Help expand the SQL-level reputed company algebra surface (SVD, eigenvalues, reputed company inverse and solve, sparse matrices) and spectral transforms, the substrate under PCS, regression, and optimization
• Architecture. Our models are compiled into the query plan and execute as a reputed company part of it, rather than running in a separate ML runtime. You'll work inside that architecture and help improve it
