Job Description

Senior Data Visualisation Engineer | TypeScript | JavaScript | SVG | Canvas | London

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.


Why engineers take this role


You work on the hard stuff

This is core library engineering: rendering engines, chart primitives, 2D graphics, and public APIs — not feature churn or framework glue.

Your skills compound, fast

You’ll deepen fundamentals that actually last: algorithms, performance, graphics, and system design. The kind of experience that makes you harder to replace and easier to trust.

Real ownership, end to end

You take features from concept through to release. No product theatre. No endless hand-offs. Just proper engineering responsibility.

Your work is visible and respected

You’ll be contributing to a well-known open-source project used in serious production environments — experience that carries weight long after this role.

A grown-up engineering culture

No outsourcing. No heroics. No late nights disguised as “passion.” High standards, good planning, and engineers who care about craft.

It future-proofs your career

As tooling gets automated, engineers who understand systems, performance, and primitives become more valuable — not less.


What you’ll be doing


  • Designing, building, testing and releasing features end-to-end
  • Working across rendering, chart types, animations, and APIs
  • Solving performance-sensitive and correctness-critical problems
  • Collaborating with other senior engineers on integrated visual systems
  • Optionally contributing to technical blogs, talks or demos


What I'm looking for

  • 5+ years building serious software (products, platforms, or libraries)
  • Strong JavaScript and/or TypeScript fundamentals
  • Experience with 2D graphics (Canvas, SVG, Processing, or similar)
  • Solid grounding in data structures, algorithms, and software design
  • Experience with at least one statically typed language
  • Working understanding of basic linear algebra


Apply in confidence.
