Reka AI builds natively multimodal models (Spark, Edge, Flash, Core) for video, image, audio, and text. Used by enterprises in security, media, and defense.
About the role
Work with model researchers to define what “good data” means for our models, including quality metrics, validation checks, and acceptance thresholds Explore open source datasets and create internal ones most suitable to build fundamental World Models
What they're looking for
- Strong ML and deep learning fundamentals with experience building and operating large-scale data and/or compute systems
- Comfortable moving between research questions and production engineering: you can dig into data, run analyses, and also ship reliable systems
- Demonstrated research experience with data compositions, quality, and dataset releases
- Ability to design and execute experiments with convincing unbiased outcomes
- Practical experience with distributed processing and orchestration (Spark, Ray, Airflow, or equivalents)
- Solid Python skills, and familiarity with the tooling around modern model training workflows (datasets, checkpoints, experiment tracking)
More about this role
In this role, you’ll work closely with model researchers, data infrastructure engineers, and cross-functional partners to make sure our data is high quality and can be produced at petabyte scale in a reliable, efficient way. From understanding how data choices show up in model behavior, to building processing pipelines and running the compute behind them, you’ll help ensure our models are trained on the best data we can get.
