Job Description
Senior Software Engineer | Data Visualisation & Graphics | London
London (Hybrid)
Salary up to £200,000 + benefits
Most engineers consume visualisation libraries.
A small number build them.
We’re working with a highly successful software company whose charting technology powers applications used by thousands of organisations worldwide, from global financial institutions to technology businesses and enterprise software providers.
As adoption continues to grow, they’re looking for a software engineer to help build the rendering systems, charting components, and visualisation infrastructure that sit at the heart of the product.
This is not a dashboard‑building role. You’ll be working on the underlying systems that make complex visualisations fast, accurate, and scalable.
The challenges range from rendering performance and interaction design through to algorithms, graphics, API design, and numerical correctness.
What you’ll be doing
- Designing and building core charting features used by developers around the world
- Working across rendering, interaction, animation, and visualisation infrastructure
- Solving performance‑critical problems involving Canvas, SVG, and large datasets
- Improving correctness, precision, and usability across a sophisticated charting platform
- Designing APIs that are elegant, flexible, and easy for developers to adopt
- Taking features from initial concept through to production release
- Collaborating with a small team of highly experienced engineers building a market‑leading product
What they’re looking for
- Strong JavaScript or TypeScript engineering skills
- Experience working with Canvas, SVG, WebGL, graphics systems, visualisation products, or rendering pipelines
- Strong understanding of algorithms, data structures, and software architecture
- Experience building complex software products rather than purely application‑layer development
- Exposure to such as C++, Java, C#, Rust, Go, or similar
- Understanding of performance optimisation and rendering trade‑offs
- Appreciation of the mathematical concepts underpinning data visualisation and graphics
- Passion for engineering quality and technical excellence
Particularly interesting backgrounds include
- Charting libraries
- Data visualisation platforms
- Graphics or rendering engines
- CAD, GIS, mapping, simulation, or scientific software
- Developer tools
- High‑performance frontend systems
- Financial technology visualisation platforms
Why this role stands out
- Build technology used by thousands of engineering teams globally
- Work on rendering and graphics problems rarely found in commercial software roles
- Join an engineering‑led organisation with exceptionally high technical standards
- High levels of ownership and autonomy
- Small team, significant impact
- Opportunity to deepen expertise in performance, graphics, visualisation, and systems design
Package
- Salary up to £200,000
- Hybrid working (London)
- Private healthcare
- PensionAdditional benefits
If you’re interested in building the technology behind modern data visualisation rather than simply consuming it, we’d be keen to speak with you.
