About the role

  • Your work will directly shape the capabilities and quality of our foundational models.
  • Define Cartesia's multi-modal data strategy across pre-training and post-training, spanning human, synthetic, and web-scale sources, with particular depth in audio.
  • Establish and enforce rigorous standards for data quality, with a tight feedback loop between dataset characteristics and model behavior.

Responsibilities

  • Design and operate scalable, high-throughput data pipelines for text, audio, and video - covering ingestion, preprocessing, augmentation, dataset versioning, and data loading for training.
  • Partner closely with research and inference teams so data systems are co-designed with training and serving infrastructure (batching, GPU-aware loading, evaluation pipelines).
  • Identify and source novel datasets; manage relationships and budgets with external data vendors and partners.
  • Our team combines deep expertise in model innovation and systems engineering paired with a design-minded product engineering team to build and ship cutting edge models and experiences.
  • We're funded by leading investors at Index Ventures and Lightspeed Venture Partners, along with Factory, Conviction, A Star, General Catalyst, SV Angel, Databricks and others.

  • Experience leading cross-functional technical efforts in a fast-moving, research-driven environment.
  • Strong modern engineering execution: clean, well-tested code, fluency with current tools, and a willingness to pick the right tool for the problem rather than defaulting to familiar patterns.
