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.
You enjoy problem-solving and thinking from first principles, and are always ready to pick up new skills and build quickly
You're happy to tackle problems without a predefined, clear definition or obvious solution, and are excited to have autonomy to make decisions as you go
You understand that being a member of a high-performing team requires two things. You contribute your best work and help others contribute their best. You'll always lend a helping hand when needed and level up those around you
Experience requirements
Strong frontend engineering experience, with production-grade work on complex, high-performance UIs
Proficiency in TypeScript and React
Experience with 3D rendering, WebGL, Canvas, or similar browser-based visualisation technologies is a strong plus
Familiarity with Python and backend development
Experience with Kubernetes and GCP is a plus
Tech stack
We are technology agnostic at Encord and not looking for experience across all of these — as long as you're open to learning, please apply.
