Job Description

About us Encord is the universal data layer for AI that helps 300+ AI teams train and run models on the right data. Our platform indexes, curates, annotates, and evaluates data across the full AI lifecycle, from development through production. Trusted by Woven by Toyota, AXA, UiPath, Zipline, and more. We're an ambitious team of 100+ working at the frontier of AI and have raised $60M in Series C funding from Wellington Management, CRV, Next47 and Y Combinator. The Role We're looking for great engineers with experience building complex UIs to help build out our editor interface — the part of our product that lets users visualise and annotate their data. We handle a wide range of data modalities, including image, video, audio, text, PDFs, medical images, and data from LiDAR and other sensors in robots and autonomous vehicles. For this role, we are particularly looking for engineers who are excited about technically challenging frontend work, such as rendering complex 3D/4D scenes with thousands of objects, combining data from several modalities, all while maintaining high performance in the browser. You'll join us at a crucial stage of accelerated development, as part of a small, highly collaborative group where you'll be a key driver of progress on a core part of our product — operating with a high degree of autonomy and crafting performant, reliable, and maintainable solutions at speed.
