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: core library engineering, rendering engines, chart primitives, 2D graphics, and public APIs — not feature churn or framework glue.
- You’ll deepen fundamentals that actually last: algorithms, performance, graphics, and system design.
- Real ownership, end to end: your work is visible and respected. You take features from concept through to release.
- 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).
- 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.
