Job description

Ascendix Technologies is an AI and Real Estate Technology partner founded in 1997 and headquartered in the United States, in Dallas, Texas. The company has branch offices in Poland, Portugal, and Ukraine, and distributed teams all over Europe, as we have cooperated remotely since 2020.

We help commercial real estate teams spend less time managing systems and more time closing deals - backed by 25+ years of hands-on experience in real estate and a full stack of AI, Salesforce, and custom development built for real estate workflows. Trusted by industry leaders who rely on us for their most critical software development initiatives.

We're looking for a Senior UI/UX Designer- someone who can turn complex problems into clear, thoughtful product experiences. You're independent by nature, confident explaining your decisions, and comfortable working closely with BAs and engineers. You're curious about AI, quick to adopt new tools, and take ownership from the first idea all the way to the released feature.

Sound like you? Here's what we're looking for.

Requirements:

• Senior-level product design: discovery, user interviews, usability testing, A/B testing, and turning research into design decisions;
• Interactive prototyping with AI-assisted design tools, not static mockups only;
• Produces structured design artefacts that development teams use as specification input (flows, states, edge cases, acceptance-level detail);
• Strong Figma skills, including components and design systems;
• SaaS product design experience, ideally data-heavy business applications;
• Strong spoken and written English for direct work with US stakeholders and users.

Would be a plus:

• Design of AI-driven product features (chat, agents, generated content);
• Experience working with spec-driven or AI-assisted development workflows;
• Building and maintaining a design system from scratch.

Responsibilities:

• Own product design for Ascendix IQ and others;
• Run discovery: user interviews, usability sessions, A/B tests, and turn findings into design decisions;
• Produce design artifacts detailed enough to feed the spec-driven development workflow: flows, screen states, edge cases, and component behavior;
• Maintain and extend the design system in Figma;
• Work daily with dev teams from idea to released feature.

Ascendix offers you:

• 20 paid vacation

Career and professional growth:

• B2B and remote cooperation
• Career development and professional growth
• Technical performance reviews and 360 Evaluation
• Collaboration with a personal Direct Manager, Technical leads, and mentors

Learning and Development:

• Internal knowledge-sharing opportunities

Corporate spirit:

• Online and offline events & team-buildings
• Friendly and supportive atmosphere
