# Udaikaran Singh > Perception @Waymo | Ex-TikTok | CMU SCS Location: San Jose, California, United States Profile: https://flows.cv/udaikaran SWE Perception @Waymo. Data curation & evaluation for foundation models. ## Work Experience ### Software Engineer @ Waymo Jan 2025 – Present | Mountain View, California, United States Perception team with focus on model evaluation for onboard models and foundation models. ### Machine Learning Engineer @ TikTok Jan 2023 – Jan 2025 | San Jose, California, United States TikTok Search Video Retrieval and Ranking (leading video indexing) - Introduced LLM to search indexing for for measuring video quality to improve content quality. - Improved search indexing by introducing OCR and adding new prediction head to the model. Improved retrieval by coverage by 20% in experimentation. - Redesigned offline indexing pipeline primarily by migrating from MapReduce to PySpark, reducing runtime of pipeline from 30 hours to 4 hours and reducing max cpu cores needed from 60k to 15k. ### Graduate Teaching Assistant @ Carnegie Mellon University Jan 2021 – Jan 2023 | Pittsburgh, Pennsylvania, United States TA for ML courses under Dr. Ruslan Salakhutdinov, Dr. Eric Nyberg, and Dr. Matt Gormley. ### Machine Learning Engineer Intern @ TikTok Jan 2022 – Jan 2022 | Mountain View, California, United States - Worked in the Trust & Safety team. - Improved the accuracy of pornographic audio detection model by 15%. - Updated TikTok codebase to support self-suprivsed learning models and self-supervised model training (e.g. Data2vec). - Develop initial multimodal model for fusion of video and audio backend models. ### Software Engineer Intern @ Agot.AI Jan 2022 – Jan 2022 | Pittsburgh, Pennsylvania, United States SWE internship focusing on computer vision algorithm development. ### Data Science Tutor @ UCSD CSE Department Jan 2018 – Jan 2021 | La Jolla, California I helped tutor an Introduction to Data Structure and Mathematics for Data Science course. I aided students in their homework and contributed to the course material through helping to create homework problem and extra study resources. ## Education ### Master of Science - MS in Artificial Intelligence Carnegie Mellon University ### Bachelor of Science - BS in Data Science UC San Diego ### Bellarmine College Preparatory ## Contact & Social - LinkedIn: https://linkedin.com/in/udaikaran-singh --- Source: https://flows.cv/udaikaran JSON Resume: https://flows.cv/udaikaran/resume.json Last updated: 2026-04-11
