Join us in building the future of responsible AI adoption and digital integrity.

Responsibilities
Manage and grow a high-performing team of AI researchers and engineers, fostering technical excellence.
Drive the design and training of multimodal models applications (Text, Image, Audio, Video) using PyTorch.
Own the AI roadmap from initial concept to scalable, high-throughput production.
Partner with Product, Backend, and Security teams to integrate AI solutions globally.
Stay at the forefront of GenAI/LLM research to continuously improve our detection engines.
Requirements
BSc in Computer Science, Mathematics, or a related quantitative field (MSc/PhD preferred).
4+ years of hands-on experience as a Data Scientist or AI Engineer, with a proven track record of training and deploying models at scale.
1+ years of experience leading or managing a technical team.
Expert-level proficiency in PyTorch and the “usual” ML stack (Python, NumPy, cikit-learn, etc.).
Demonstrated experience working with at least two of the following domains: NLP, Computer Vision, Audio processing, or Video analysis.
Experience with Cloud-native environments (GCP preferred), Docker, and Kubernetes.
Familiarity with modern LLM frameworks (Transformers, Peft, TRL, LangChain, etc.).
Experience building and maintaining distributed data pipelines for ML training.
