Software Engineer | Canvas | SVG | High-Performance Charting | London to £200,000 depending on exp. Most data visualisation roles sit on top of libraries. This one builds the engine behind them. I’m hiring a Senior Engineer to work on a widely-used charting library used by thousands of developers building data-intensive applications. This is core product engineering — focused on rendering, performance, correctness, and API design. This is not a typical frontend role. You’ll be working closer to a graphics engine than an application layer. What you’ll be doing • Designing and building core features across rendering, chart types, animations, and APIs, • Solving performance-critical problems in Canvas and SVG, • Working on correctness and precision in data visualisation, • Taking features end-to-end — from design through to release, • Collaborating with senior engineers on a highly integrated visual system, • Optionally contributing to technical content, demos, or talks What they’re looking for • Strong JavaScript or TypeScript fundamentals, • Experience working with Canvas, SVG, or other 2D graphics systems, • Solid grounding in algorithms, data structures, and software design, • Experience building complex systems — not just application-layer UI, • Exposure to a statically typed language (C++, Java, C#, Rust, etc.), • Understanding of performance trade-offs in rendering and interaction, • Working knowledge of basic linear algebra Why this role stands out • You’ll be working on core library and graphics problems, not UI glue code, • The work is visible — used in production by engineering teams globally, • You’ll deepen skills that compound: performance, systems thinking, and rendering, • High ownership — no layers of process or unnecessary handoffs, • Engineering-led culture with high standards and low noise Package • Salary up to £200,000, • Hybrid working (London-based), • Private healthcare, pension, and additional benefits If you’ve ever wanted to move beyond dashboards and into building the systems that power them, this is that opportunity.

We are working with a Series A AI technology company building automation software that sits directly in the operational core of key businesses. This is not experimental AI. This is production critical software used daily by hundreds of customers. This is a hands on individual contributor role suited to engineers who want ownership, pace, and impact without layers of process getting in the way. What you will be doing: • Designing, building, and maintaining backend services and APIs using Flask & FastAPI, • Building and evolving user facing web components using React/TypeScript, • Integrating third party services and AI models into production workflows, • Investigating production issues and contributing to root cause analysis, • Collaborating closely with product, operations, and non technical stakeholders, • Participating in code reviews and shaping engineering standards What they are looking for: • Someone who genuinely enjoys building and shipping software frequently, • Strong problem solving ability with a pragmatic engineering mindset, • Comfort owning features end to end from build through deployment, • A bias to action while still caring about scalability and reliability, • Ability to work across the stack or depth in one area with curiosity in others, • Experience with Python based backend systems and modern frontend frameworks They value engineers who focus on outcomes over perfection, who simplify rather than over-engineering, and who take responsibility rather than waiting for instruction. What you can expect: • Meaningful equity, • London based role (hybrid) with regular in person collaboration & opportunities for international travel, • Extensive company benefits This role will suit engineers who want to work close to the product, close to customers, and close to real world impact.
