About Us

Base360.ai is the AI operating system for B2C brands, a platform that lets operators run their entire business on autopilot. Born out of a fast-growing short-term rental operator that scaled to an 8-figure portfolio on its own software, Base360.ai is now launching as a standalone product to power the next generation of consumer brands.

We're expanding globally and seeking a world-class UX/UI Designer to help us create intuitive, beautiful, and high-converting product and marketing experiences.

Role Overview

As a UX/UI Designer, you'll be responsible for turning complex workflows into delightful user experiences across Base360.ai's product, marketing site, and customer touchpoints. You'll work directly with the CEO, product managers, and engineers to design features that solve real problems for B2C brands — and look stunning while doing it.

You Will

  • Work on Base360.ai's core product, designing intuitive dashboards, workflows, and integrations.
  • Create marketing assets including our main landing pages, product pages, and demo flows.
  • Help define and maintain our design system for speed and consistency.
  • Gather user feedback to iterate and improve designs rapidly.
  • Shape the Base360.ai brand as it grows.

Key Responsibilities

  • Translate product requirements into wireframes, prototypes, and final UI designs in Figma.
  • Build conversion-focused landing pages for product launches and campaigns.
  • Ensure a consistent visual language across all product modules and touchpoints.
  • Collaborate closely with developers to ensure pixel-perfect implementation.
  • Conduct user research, usability testing, and A/B experiments.
  • Maintain and expand our design system and component library.

Why Join Base360.ai?

  • Be part of an innovative and fast-growing company building the AI operating system for B2C brands.
  • Opportunity to build a team and establish a long-term presence in one of Europe's most vibrant cities.
  • Competitive salary and performance-based incentives.
  • A chance to grow professionally in a hands-on, entrepreneurial role.

You Should NOT Apply If

  • You are looking for a corporate 9 to 5 job.
  • You are political and enjoy gossiping and talking about people behind their backs.
  • You are looking for a stable and slow dead-end job.
  • You do not aim to be one of the best in the world at what you do.
