Senior Software Engineer | Charts Engineer | Data Visualisation | JavaScript | TypeScript London | to £200,000 depending on exp. I'm hiring a Senior Engineer to work on a widely-used, open-source charting library relied on by thousands of engineers building data-intensive products. This is not a typical frontend role.

You’ll be working at the heart of a graphics and visualisation engine — solving problems around rendering, performance, correctness, and API design. You’ll deepen fundamentals that actually last: algorithms, performance, graphics, and system design. You’ll be contributing to a well-known open-source project used in serious production environments — experience that carries weight long after this role.

High standards, good planning, and engineers who care about craft. As tooling gets automated, engineers who understand systems, performance, and primitives become more valuable — not less.
