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, 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.
