About the role

Key responsibilities & impact

Build and maintain components, patterns, and tokens in Purse, partnering closely with engineering to ensure design–code parity across web, mobile, and tablet
Write and maintain component documentation that serves designers, engineers, and AI tools — including usage rules, anatomy, variants, accessibility, and worked examples
Run audits, support product designers, and turn recurring needs into systemic improvements, working alongside the Design System Manager to evolve Purse toward our long-term vision through incremental, high-value milestones

Requirements

What you’ll need

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 waiting for the perfect end state
You are pragmatic: you don't overthink, you don't always work by the book, and you know when a "good enough" solution beats a perfect one
You are curious about how design systems are evolving in 2026 (AI, codegen, token automation, MCP)
You enjoy switching between deep craft work and pragmatic system-level decisions
Strong technical acumen with a clear understanding of how design systems are implemented in code
Comfortable working in a production-first environment where code is the source of truth, and Figma reflects what ships
Experience partnering with engineering teams to ensure design–code parity and smooth implementation of new components
Experience supporting product designers through office hours, a support model, or peer review
Demonstrated ability to evangelize a design system, present design rationale, and translate component-level decisions for non-design stakeholders
Ability to handle complex support requests and turn recurring questions into permanent improvements (docs, lint rules, worked examples)
Nice to have: Experience with B2B SaaS products or fintech environments
Nice to have: Familiarity with multi-language / internationalization design challenges
Nice to have: Experience contributing to or maintaining a tokens pipeline (Style Dictionary, Tokens Studio, MCP-based pipelines)
Nice to have: Background in accessibility standards and inclusive design practices
Nice to have: Experience working in fast-growing scale-ups
