Frontend Graphics Engineer | High-Performance Charting

Frontend Graphics Engineer | High-Performance Charting | London to £200,000 depending on exp. Most data visualisation roles sit on top of libraries. This one builds the engine behind them.

I’m hiring a Senior Engineer to work on a widely-used charting library used by thousands of developers building data-intensive applications. This is core product engineering — focused on rendering, performance, correctness, and API design. This is not a typical frontend role.

You’ll be working closer to a graphics engine than an application layer. What you’ll be doing Designing and building core features across rendering, chart types, animations, and APIs Solving performance-critical problems in Canvas and SVG Working on correctness and precision in data visualisation Taking features end-to-end — from design through to release Collaborating with senior engineers on a highly integrated visual system Optionally contributing to technical content, demos, or talks What they’re looking for Strong JavaScript or TypeScript fundamentals Experience working with Canvas, SVG, or other 2D graphics systems Solid grounding in algorithms, data structures, and software design Experience building complex systems — not just application-layer UI Exposure to a statically typed language (C++, Java, C#, Rust, etc.) Understanding of performance trade-offs in rendering and interaction Working knowledge of basic linear algebra Why this role stands out You’ll be working on core library and graphics problems, not UI glue code The work is visible — used in production by engineering teams globally You’ll deepen skills that compound: performance, systems thinking, and rendering High ownership — no layers of process or unnecessary handoffs Engineering-led culture with high standards and low noise Package Salary up to £200,000 Hybrid working (London-based) Private healthcare, pension, and additional benefits If you’ve ever wanted to move beyond dashboards and into building the systems that power them, this is that opportunity.
