Karya is building the data infrastructure for the next generation of AI. We work across languages and real-world contexts to create high-quality datasets and evaluations, while creating meaningful digital work for underserved communities. We’re looking for a Senior Backend Engineer to take ownership of important parts of our platform and help shape the next generation of Karya’s engineering infrastructure.
