This role is ideal for an engineer who is equally comfortable training and evaluating models, designing production-ready pipelines, and shipping tools that help internal teams make better decisions. You'll work across computer vision, structured data, and agentic AI workflows, with direct impact on products used by graders, researchers, and collectors. You'll partner closely with product, engineering, operations, and domain experts to turn ambiguous problems into measurable, reliable ML solutions. What You'll Do * Design, build, and deploy end-to-end machine learning systems that support AI/ML product initiatives * Own projects from problem framing through implementation, evaluation, launch, and post-launch monitoring, with clear accountability for outcomes * Develop production-grade computer vision, multimodal, and agentic pipeline solutions that can ingest images and other inputs, reason over uncertainty, and return structured, reliable outputs * Build and improve data pipelines, model evaluation frameworks, and feedback loops that ensure training and inference systems remain accurate, scalable, and maintainable over time * Partner with annotation, operations, product, and domain experts to define data requirements, labeling standards, success metrics, and rollout plans * Translate experimental findings into clear technical recommendations, balancing model quality, latency, cost, and operational complexity * Contribute high-quality code, documentation, and technical design artifacts, and collaborate effectively through design reviews, code reviews, and cross-functional discussions, U.S. residents: for disclosures relating to personal information we collect during the employment application and recruitment process, please see ourPrivacy Notice for U.S. Applicants.
