Company Overview: We are building Protege to solve the biggest unmet need in AI — getting access to the right training data. The process today is time intensive, incredibly expensive, and often ends in failure. The Protege platform facilitates the secure, efficient, and privacy-centric exchange of AI training data.
Solving AI’s data problem is a generational opportunity. We’re backed by world-class investors and already powering partnerships with some of the most ambitious teams in AI. The company that succeeds will be one of the largest in AI — and in tech.
We’re a lean, fast-moving, high-trust team of builders who are obsessed with velocity and impact. Our culture is built for people who thrive on ambiguity, own outcomes, and want to shape the future of data and AI.
Data is the foundation of AI performance, and we believe model quality starts with data quality. You’ll be at the heart of shaping how we curate, assess, and prepare the training data that powers real-world AI systems.
We’re seeking a Senior Member of the Core Data Team to lead the evaluation and optimization of large-scale datasets used to train state-of-the-art AI models. In this role, you’ll help define what "high-quality data" means in practice, using statistical, computational, and ML-driven methods to ensure our data is diverse, representative, and high-impact. You’ll work closely with research and engineering teams to improve model performance through better data. This is an ideal role for someone with a PhD in machine learning, CS, or a related applied field who is passionate about the role of data in AI training and excited to advance Protege’s mission to become the ubiquitous platform for AI training data.
