Company mission
To bring quantum computing to society and use cases with great impact on society and on the technological wealth of the national and international territory.
Role
Who you are
- 2–5 years of experience as a UI/UX Designer, Product Designer, or similar role working on modern web applications
- Strong proficiency in Figma (design systems, auto-layout, component libraries, prototyping)
- Demonstrated ability to design complex dashboards, data-heavy UIs, configuration screens, and workflow-oriented applications
- Solid understanding of user-centered design, information architecture, interaction design, and usability principles
- Experience collaborating closely with product managers and engineers to translate business needs into intuitive user flows
- Ability to deliver production-ready UI specs, design tokens, component references, and clear documentation for developers
- Comfortable running lightweight user research: interviews, usability testing, concept validation, heuristic evaluation
- Strong visual design skills: spacing, layout, typography, hierarchy, consistency
Desirable
- Experience designing interfaces for AI/ML tools, LLM-powered products, or automation workflows
- Familiarity with design systems used in modern frontend stacks (Tailwind, ShadCN, Material UI)
- Experience with data visualization and storytelling (charts, tables, metric views, drill-down patterns)
- Ability to work in fast iteration cycles, supporting experiments and internal prototypes
- Understanding of how engineering constraints influence design decisions — ability to balance feasibility and UX quality
- Experience defining or maintaining a Design System for consistency across multiple internal tools
- Bonus: basic familiarity with frontend technologies (React, TypeScript) to improve designer–developer collaboration
What the job involves
- Own the end-to-end design process for internal and customer-facing products: discovery → flows/wireframes → UI/UX → handoff
- Create clean, scalable UI designs for dashboards, account management tools, configuration panels, and LLM-driven interfaces
- Build and maintain a Figma component library aligned with our engineering stack
- Collaborate daily with product managers, engineers, and domain experts in AI/quantum to translate highly technical concepts into usable interfaces
- Conduct small research loops with users and internal stakeholders to validate assumptions and improve the product experience
- Ensure design consistency and accessibility across applications
- Fixed-term contract ending in June 2026
Application process
- We are looking to fill this role immediately and are reviewing applications daily. Expect a fast, transparent process with quick feedback
