JavaScript TypeScript Engineer | D3 | SVG | Canvas | Data Visualisation | 2D Graphics

• *JavaScript TypeScript Engineer | D3 | SVG | Canvas | Data Visualisation | 2D Graphics
• *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.**
