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.
