Job Title: Senior Full-Stack Engineer (Front-End Leaning) at Encord

Salary: £80-150k + Equity

Company Description: Encord - Series C AI infrastructure platform backed by CRV and Y Combinator

Job Description:
You will lead development of Encord’s sophisticated editor interface, solving high-performance rendering challenges for multimodal AI datasets. Operating with end-to-end ownership, you’ll build systems that visualize complex 3D scenes and LiDAR data in the browser. This role is perfect for engineers who enjoy the intersection of computer vision, graphics-heavy front-end development, and physical AI infrastructure.

Location: London, UK

Why this role is remarkable:

• Work on cutting-edge browser-based visualization for massive datasets including LiDAR, 3D point clouds, and medical imaging at a scale of 5+ petabytes.

• Join a high-growth leader that recently raised $60M in Series C funding at a $550M valuation to power the next generation of physical AI and robotics.

• Enjoy high autonomy and end-to-end ownership in a small, elite engineering team composed of veterans from Oxford CS, Meta, and top-tier startups.

What you will do:

• Design and implement complex, performance-critical UI components for rendering thousands of objects in 3D/4D scenes at 60fps using TypeScript and React.

• Lead full-stack projects from architectural decisions and product design through to deployment, monitoring, and measuring direct customer impact.

• Collaborate with a high-performing team to build simple, robust solutions for managing multimodal data used by industry giants like Toyota and Skydio.

The ideal candidate:

• Deep expertise in TypeScript and React with a proven track record of building complex, rendering-intensive web interfaces or graphics tools.

• Strong foundation in Computer Science with experience in canvas rendering, WebGL, or GPU-accelerated graphics within a production environment.

• A proactive builder mentality, comfortable navigating ambiguity and moving across the stack (Python/Rust) to ensure reliable, performant product delivery.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
