We bring characters to life, transforming how people tell stories, connect, and create. We build and power ecosystems. Cantina, our flagship social AI platform, is just the beginning.\nAbout the Role:\nCantina is expanding, and we're looking for an ML Engineer to join our growing Singapore team! In this role, you will build and scale systems for ingesting, processing, and delivering large-scale video and multimodal data for model training. You'll own the full pipeline - from raw content to curated, filtered, and training-ready datasets - with a focus on speed, reliability, reproducibility, and cost-efficiency. You'll partner closely with curation and modeling teams to operationalize evolving dataset recipes and iterate on approaches that improve model outcomes.\nWhat You’ll Do:\nDesign and scale distributed data pipelines for preprocessing, dataset generation, and repeated dataset refreshes\n\nOwn workflow orchestration, job scheduling, monitoring, and failure recovery for large-scale data processing jobs\n\nImplement and maintain containerized pipeline infrastructure using Kubernetes or equivalent orchestration systems\n\nOptimize cloud-based data storage and movement across providers (AWS, GCS, or Azure) for cost, throughput, and operational efficiency\n\nDefine and implement best practices for dataset storage layout, versioning, caching, retention, and access patterns\n\nDesign and implement curation pipelines that determine which video and image content is selected, filtered, and retained for model training, including image-text pair datasets used in joint training regimes\n\nBuild and improve VLM-based captioning and metadata generation workflows at scale across both video and image data\n\nDevelop and apply quality and aesthetic scoring models, CLIP-based semantic filtering, and other signal-extraction approaches for data selection\n\nBuild tooling to support deduplication workflows at scale, including near-dedup and exact deduplication pipelines over large video corpora\n\nAnalyze dataset composition, identify quality issues, and iterate on curation logic to improve training outcomes\n\nDefine and evolve standards for what constitutes high-quality, training-ready video data across different training regimes\n\nWhat You’ll Bring:\nStrong hands-on experience building or scaling large-scale data systems and pipelines for machine learning, including dataset curation, filtering, and quality improvement\n\nExperience with distributed data processing frameworks such as PySpark or Ray, and orchestration tools such as Airflow or equivalent\n\nFamiliarity with containerization and container orchestration, including Docker and Kubernetes\n\nExperience working with cloud-based data storage and compute (AWS, GCS, and/or Azure), including tradeoffs around cost, throughput, storage layout, and access patterns\n\nExperience with VLM-based captioning pipelines or quality/aesthetic scoring models for video or image data, including curation of image-text pair datasets for joint image-video training\n\nFamiliarity with CLIP-based or embedding-based filtering and semantic data selection techniques\n\nFamiliarity with video and media processing tools such as FFmpeg, PyAV, DALI, or OpenCV, and relevant libraries such as Decord, torchvision, PyTorchVideo, or torchaudio\n\nProficiency in Python\n\nStrong problem-solving, communication, and documentation skills\n\nBenefits We Offer:\nCompetitive salary and generous company equity\n\nPersonal time off and paid holidays\n\nHealth insurance\n\nGlobal travel insurance: Covers you when traveling internationally\n\nMonthly spending stipend: $500 (~S$635)\n\nEquipment: All equipment needed for your home office","description_format":"text","description_chars":3812,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Health
