What you'll do Suitcase is Perk's design system, supporting 25+ designers and the engineers who build with them across web and mobile. Our ambition is for it to be a complete, consumer-grade, accessible and distributable system, so Perk feels like one consistent product on every surface our customers use, including AI agents and assistants. As a Senior Design Systems Designer you'll own the craft and visual direction of Suitcase, and work with front-end engineers, content designers and product designers to make high quality design the default standard. You will: Set the direction for Suitcase with design and engineering leadership, turn the vision into a roadmap with named resources, and report progress against it.

Own the visual language, token architecture, and foundations of Suitcase: typography, colour, space, motion, and interaction states.

Work with content design and localisation on content tokens, so components carry their language requirements.

Design, document, and refine components with complete states, variants, platform coverage and usage guidance.

Write component specs that AI prototyping tools can read, so generated prototypes use real Suitcase components and tokens.

Bring components to WCAG 2.2 AA, and make conformance part of how new components are built and reviewed.

Define adoption, component health, accessibility, and Figma-to-code parity measures with engineering, and report against them.

Run the contribution governance model, with defined routes for components between an experimental layer and the core system.

Champion Suitcase across Builders, explain the reasoning behind decisions, and coach designers and engineers on using and contributing to the system.

What you'll need Strong product design experience, including time spent designing and scaling design systems for a fast-growing product on web and mobile.

A deep grasp of typography, colour, layout, motion, and micro-interactions.

Judgement on when the system needs a new component and when an existing one should be used.

Experience designing and maintaining token systems, including naming, theming, documentation, and Figma-to-code workflows, and working knowledge of HTML, CSS and JavaScript.

Practical experience designing components for WCAG 2.2 AA standards, including keyboard and screen-reader behaviour.

Experience prototyping with AI tools and with Storybook, Code Connect and MCP tooling, and an understanding of how they connect design systems to code and AI tools.

The ability to take non-designers from the problem to the decision to the outcome and build adoption by persuasion.

A clear opinion of what good looks like, and the ability to make trade-off decisions and defend them.

Experience using customer insight from research, support and sales as well as team data, and taking ownership of business outcomes.

A clear voice in shaping roadmap, sequencing and scope, and the ability to push back, including when the system is being bypassed, without damaging the relationship.

Experience integrating or consolidating design systems.

Familiarity with content and localisation considerations in components.

AI at Perk AI is embedded in how we work across every function. The tools you'll use day-to-day are AI-enabled so you can move faster and spend more time on the work that matters. In practice, that means using AI to research and prioritise accounts, draft and refine outreach, handle customer interactions more effectively, synthesise information, and cut through shadow work - the invisible tasks that pull people away from the work only they can do - so you can focus on relationships and outcomes.
