Software Engineer (UI/UX Designer) (Fixed-term contract)

We are looking to fill this role immediately and are reviewing applications daily. Expect a fast, transparent process with quick feedback.

Why join us?

We are a European deep‑tech leader in quantum and AI, backed by major global strategic investors and strong EU support. Our groundbreaking technology is already transforming how AI is deployed worldwide — compressing large language models by up to 95% without losing accuracy and cutting inference costs by 50–80%. Joining us means working on cutting‑edge solutions that make AI faster, greener, and more accessible — and being part of a company often described as a “quantum‑AI unicorn in the making.”

We offer

• Competitive annual salary starting from €45,000, based on experience and qualifications.
• Two unique bonuses: signing bonus at incorporation and retention bonus at contract completion.
• Relocation package (if applicable).
• Fixed‑term contract ending in June 2026.
• Hybrid role and flexible working hours.
• Be part of a fast‑scaling Series B company at the forefront of deep tech.
• Equal pay guaranteed.
• International exposure in a multicultural, cutting‑edge environment.

What you’ll do

• 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.

Required Qualifications

• 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.

Preferred Qualifications

• 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.
