Job description

Software Engineer | Canvas | SVG | 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.
