Design sits at the centre of this mission and its purpose is to deliver a seamless, accessible and enjoyable experience for our users. Our team of 40+ product designers work across different tracks that are divided into cross-functional squads each consisting of Engineering, Product and Design. Autonomy, trust and transparency are the key values upon which our culture is built, this is directly reflected in how our designers operate on a day-to-day basis.

At Pennylane, designers are expected to actively contribute all the way from defining the problem space, to research and testing.

We are seeking a Design System Designer to grow and maintain Purse, our design system, alongside our Design System Manager.

You’ll partner closely with engineering on design–code parity, with product designers as their support for system usage, and with our Design System Manager on the long-term direction of Purse.

• Hands‑on experience contributing to a design system at scale: designing components, defining variants and APIs, modeling tokens, and maintaining Figma libraries used by 40+ designers

• Strong understanding of design token systems, semantic naming, and theming / multi‑brand patterns

• Skilled at running design system audits, spotting inconsistencies in product surfaces, and bringing them back into the system

• Experience writing component documentation that is clear for designers, engineers, and product managers

• Expertise in what makes a design system interpretable and usable by AI: structured content, machine-readable patterns, AI‑ready documentation conventions, and how an LLM or codegen agent consumes a design system

• Solid grounding in accessibility (WCAG) and inclusive design practices

• You want to push the design system toward an ambitious vision, but you know how to slice the path into small intermediate milestones that deliver value at every step, rather than…
