Description

Portuguese B2B fintech and software house with over 120 employees building digital products for the banking sector. The company runs a white-label Design System in production that serves multiple brands. The challenge is to evolve the system for product teams and structure it so it can be consumed not only by humans but also by LLMs as context for AI agents. Work is 100% remote with collaboration, autonomy and trust.

Responsibilities

Design, iterate and document DS components and patterns, ensuring they work well across different brands and product contexts
Evolve the architecture of semantic and brand tokens for scalable multi-brand theming
Document the DS in a structured, adoption-oriented way – decision rationale, usage guidelines, accessibility and governance, readable by teams and LLMs
Create clear handoffs per feature – flows, states and responsive behaviour
Improve the design-to-dev workflow with Figma Dev Mode, Figma MCP and Claude
Audit adoption, identify detaches and overrides, and turn signals into concrete improvements
Review implemented features, validating consistency, usability and accessibility
Participate in DS governance: triage, contributions and backlog prioritization with the Lead

Requirements

3 to 6 years of experience in UX/UI or Product Design, with at least 2 years focused on design systems
Portfolio with real DS work – creation of components, patterns, documentation
Advanced command of Figma: variants, properties (boolean, instance swap, text), slots, variables and extended collections for multi-mode theming, plus use of internal or third-party plugins that speed up DS work
Experience with Figma Dev Mode and a clear understanding of developer handoff
Solid understanding of design tokens (primitives, semantic, component)
Experience with Figma MCP and use of Claude (or other LLMs) in the design workflow
Direct collaboration with frontend developers; ability to clarify constraints with backend when necessary
Command of accessibility and responsive design applied to components
Organized, detail-oriented profile with autonomy to execute and judgment on when to involve the Lead
Experience with white-label or multi-brand DS will be an advantage
Familiarity with Storybook, ZeroHeight or equivalents will be an advantage
