These datasets are used to power our generative audio models. \nYour work will create the foundational dataset that powers our research by building robust, scalable systems for linking, deduplicating, reconciling, and enriching data at massive scale. This role centers on high-impact bulk ingestion and advanced data linkage. You will design the logic, algorithms, and strategies that transform many independent datasets into a unified, high-quality canonical asset used throughout the company.\nYou will collaborate closely with ML researchers and product teams, working with tools such as BigQuery, Dataflow/Beam, TFRecords, and-where beneficial-distributed systems frameworks like Ray. Familiarity with ML workflows using JAX or multihost training is a plus, as the datasets you produce will directly support that ecosystem.\nWhat You'll Do\nBuild high-throughput bulk ingestion workflows to integrate datasets from multiple external providers. \nDesign and implement scalable entity-resolution solutions, including record linking, deduplication, clustering, and conflict arbitration. \nCreate and refine matching logic, decision rules, and similarity functions to align datasets with high accuracy and strong coverage. \nDefine and track data quality indicators, such as overlap metrics, match precision/recall, duplicate rates, and completeness. \nPrepare training-ready datasets in formats such as TFRecords, and structure data to meet ML research requirements. \nDevelop processing components using Dataflow (Beam) and manage large analytical workloads in BigQuery. \nLeverage frameworks like Ray to accelerate large-scale experiments, feature extraction, and research-oriented data preparation. \nCollaborate with ML researchers to anticipate downstream requirements and evolve linkage strategies as new sources and use cases emerge. \nWhat We're Looking For \nExperience working with large, heterogeneous datasets from multiple providers or domains. \nStrong background in entity resolution, deduplication, data unification, or related large-scale data integration techniques. \nProficiency in Python, with an emphasis on efficient, scalable data processing. \nExperience with BigQuery, Google Dataflow/Apache Beam, or similar batch-processing frameworks. \nFamiliarity with data validation, normalization, reconciliation, and building consistent views across diverse data sources. \nAbility to craft well-structured matching and decision strategies that balance accuracy, completeness, and computational efficiency. \nComfortable iterating quickly on pragmatic solutions, balancing correctness with time-to-delivery. \nClear communication skills and the ability to collaborate closely with ML and research teams. \n Nice to Have\nKnowledge of architecting Google Cloud Platform systems at scale\nExperience with distributed compute frameworks such as Ray, Spark, or Flink. \nUnderstanding of JAX-based ML pipelines, multihost training setups, or large-scale data preparation for accelerator-backed workflows. \nFamiliarity with TFRecords or other high-volume training data formats. \nExposure to ranking, clustering, or statistical similarity modeling. \nExperience with Go, NextJS, and/or React Native to contribute to full-stack development\nWhy Join Us\nYou will design the core dataset that underpins our research, product development, and generative audio models. \nYou'll work on large-scale data challenges that require creativity, algorithmic thinking, and engineering excellence.\nYou'll join a small, fast-moving team where your decisions shape the direction of our data and research capabilities.\nBenefits\nHighly competitive salary and equity \nQuarterly productivity budget\nFlexible time off\nFantastic office location in Manhattan\nProductivity package, including ChatGPT Plus, Claude Code, and Copilot\nTop notch private health, dental, and vision insurance for you and your dependents\n401(k) plan options with employer matching \nConcierge medical/primary care through One Medical and Rightway\nMental health support from Spring Health\nPersonalized life insurance, travel assistance, and many other perks\nUdio’s success hinges on hiring great people and creating an environment where we can be happy, feel challenged, and do our best work. \nUdio provides equal employment opportunities (EEO) to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability, genetics, sexual orientation, gender identity, or gender expression. We are committed to a diverse and inclusive workforce and welcome people from all backgrounds, experiences, perspectives, and abilities.\nThis role is eligible for a compensation package of base salary, equity, and benefits.
