multi-sensor data\r\nCreate robust backfill and reprocessing frameworks for historical data\r\nApply new filters, synchronizations, label corrections, and metadata enrichments across large datasets\r\nEstablish lineage, versioning, and reproducibility standards for ML experiments\r\nBuild dataset discovery and access APIs/SDKs for downstream users\r\nEnable teams to query datasets by time, region, modality, labels, and quality flags\r\nInstrument data quality metrics across completeness, corruption, drift, label density, class balance, and regional coverage\r\nBuild dashboards, alerts, and canary dataset builds to improve data reliability\r\nOptimize storage layouts for fast reads, parallelization, compression, chunking, sharding, locality, and prefetching\r\nPartner closely with ML, perception, hardware, and product teams to map data contracts to model needs\r\nWhat We're Looking For\r\nStrong experience building data platforms, ML infrastructure, or large-scale data processing systems\r\nExperience owning dataset quality, reproducibility, lineage, and evaluation fidelity\r\nStrong Python experience and comfort with modern data tooling\r\nExperience with tools such as PyArrow, Polars, Pandas, NumPy, SciPy, or similar libraries\r\nExperience working with audio, vision, telemetry, sensor, or time-series data\r\nStrong understanding of data pipelines, dataset versioning, metadata, and quality monitoring\r\nExperience building APIs, SDKs, or access layers for data discovery and consumption\r\nAbility to design systems that support both real-time and historical reprocessing workflows\r\nComfort working closely with ML, perception, hardware, and product teams\r\nStrong ownership, technical judgment, and ability to operate in a fast-moving startup environment\r\nBonus Experience\r\nExperience owning “dataset-as-a-product” systems used across multiple model families\r\nExperience building curated corpora with strong lineage, documentation, and reproducibility\r\nExperience designing dataset splitting or sampling strategies by time, platform, geography, class, signal quality, or similar dimensions\r\nExperience preventing data leakage and improving model generalization through thoughtful dataset design\r\nHands-on experience with labeling workflows, ontologies, consensus systems, QA, or label-store integrations\r\nExperience with Go, Rust, or TypeScript for services\r\nExperience with orchestration tools such as Airflow or Prefect\r\nExperience with metadata and lineage tools such as MLflow or Weights & Biases\r\nExposure to edge
