We're a small, cross-functional team focused on building AI systems that reason and code. We care deeply about understanding how people interact with these systems and how we can use data to make them safer, smarter, and more useful. We're looking for a Data Engineer to build and own the pipelines and data infrastructure that power our product and research efforts. Your work will directly support model training, evaluation, product analytics, and safety systems. You'll partner closely with team members building our coding agents to make sure we're capturing the right signals and using them well. If you're excited about turning messy product data into actionable insights, and building systems that can scale with our research, we'd love to get connected!
