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.
What you'll do
-
Build and own complex UI and editor interfaces for visualising and annotating multi-modal data
-
Render high-performance 3D/4D scenes with thousands of objects in the browser
-
Work across the full stack when needed, from backend services to deployment and styling
-
Take end-to-end ownership of projects, from product and architectural decisions through to deployment, monitoring, and measuring user impact
-
Collaborate closely with a lean, high-trust team to tackle challenging problems together
-
Take initiative, be proactive in problem-solving, and continuously seek improvements
Who we're looking for
-
You've seen and built a lot. You have personally developed and maintained multiple systems from scratch, and you know what trade-offs are involved in building reliable, performant software at speed
-
You want your work to have a tangible outcome for people. You're not satisfied with building products that do not see the light of day
-
You are a builder. You enjoy all aspects of building not only software but a complete product, and are comfortable moving across the stack when necessary.
