Senior Software Engineer – Data Visualisation & Graphics | London

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

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.
