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. Company details shared at first conversation.
